  • Primefaces datatable in-cell edit to update other rows in the same datatable with ajax rowEdit event processing

    - by Java Thu
    I have issue to update other rows in the same datatable when one row updated using primeface datatable in-cell edit ajax rowEdit. But failed to update other row with ajax call. The ajax response only return the same row data which was updated. The codes are as following: <h:form id="testForm"> <p:dataTable id="testDT" var="d" rowIndexVar="rowIndex" value="#{testBean.lists}" editable="true"> <p:column> <f:facet name="header">No</f:facet> <h:outputText value="#{rowIndex}" /> </p:column> <p:column headerText="Value"> <p:cellEditor> <f:facet name="output"> <h:outputText value="#{d.value}" /> </f:facet> <f:facet name="input"> <p:inputText value="#{d.value}" size="5" /> </f:facet> </p:cellEditor> </p:column> <p:column headerText="Edit" style="width:50px"> <p:outputPanel rendered="#{d.editable}"> <p:rowEditor> </p:rowEditor> </p:outputPanel> </p:column> <p:ajax event="rowEdit" update=":testForm:testDT" listener="#{testBean.onRowUpdate}" /> </p:dataTable> </h:form> My TestBean: package web.bean.test;

  • WPF storyboard animation issue when using VisualBrush

    - by Flack
    Hey guys, I was playing around with storyboards, a flipping animation, and visual brushes. I have encountered an issue though. Below is the xaml and code-behind of a small sample I quickly put together to try to demonstrate the problem. When you first start the app, you are presented with a red square and two buttons. If you click the "Flip" button, the red square will "flip" over and a blue one will appear. In reality, all that is happening is that the scale of the width of the StackPanel that the red square is in is being decreased until it reaches zero and then the StackPanel where a blue square is, whose width is initially scaled to zero, has its width increased. If you click the "Flip" button a few times, the animation looks ok and smooth. Now, if you hit the "Reflection" button, a reflection of the red/blue buttons is added to their respective StackPanels. Hitting the "Flip" button now will still cause the flip animation but it is no longer a smooth animation. The StackPanels width often does not shrink to zero. The width shrinks somewhat but then just stops before being completely invisible. Then the other StackPanel appears as usual. The only thing that changed was adding the reflection, which is just a VisualBrush. Below is the code. Does anyone have any idea why the animations are different between the two cases (stalling in the second case)? Thanks. <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xml:lang="en-US" xmlns:d="http://schemas.microsoft.com/expression/blend/2006" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="WpfFlipTest.Window1" x:Name="Window" Title="Window1" Width="214" Height="224"> <Window.Resources> <Storyboard x:Key="sbFlip"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="redStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.4" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.4" Storyboard.TargetName="blueStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.8" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <Storyboard x:Key="sbFlipBack"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="blueStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.4" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.4" Storyboard.TargetName="redStack" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.8" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </Window.Resources> <Grid x:Name="LayoutRoot" Background="Gray"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <StackPanel Name="redStack" Grid.Row="0" Grid.Column="0" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform/> </StackPanel.RenderTransform> <Border Name="redBorder" BorderBrush="Transparent" BorderThickness="4" Width="Auto" Height="Auto"> <Button Margin="0" Name="redButton" Height="75" Background="Red" Width="105" /> </Border> <Border Width="{Binding ElementName=redBorder, Path=ActualWidth}" Height="{Binding ElementName=redBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent" BorderThickness="4" Name="redRefelction" Visibility="Collapsed"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=redButton}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <StackPanel Name="blueStack" Grid.Row="0" Grid.Column="0" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform ScaleX="0"/> </StackPanel.RenderTransform> <Border Name="blueBorder" BorderBrush="Transparent" BorderThickness="4" Width="Auto" Height="Auto"> <Button Grid.Row="0" Grid.Column="1" Margin="0" Width="105" Background="Blue" Name="blueButton" Height="75"/> </Border> <Border Width="{Binding ElementName=blueBorder, Path=ActualWidth}" Height="{Binding ElementName=blueBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent" BorderThickness="4" Name="blueRefelction" Visibility="Collapsed"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=blueButton}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <Button Grid.Row="1" Click="FlipButton_Click" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76">Flip</Button> <Button Grid.Row="0" Grid.Column="1" Click="ReflectionButton_Click" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76">Reflection</Button> </Grid> </Window> Here are the button click handlers: using System;

} bool flipped = false; private void FlipButton_Click(object sender, RoutedEventArgs e) { Storyboard sbFlip = (Storyboard)Resources["sbFlip"]; Storyboard sbFlipBack = (Storyboard)Resources["sbFlipBack"]; if (flipped) { sbFlipBack.Begin(); flipped = false; } else { sbFlip.Begin(); flipped = true; } } bool reflection = false; private void ReflectionButton_Click(object sender, RoutedEventArgs e) { if (reflection) { reflection = false; redRefelction.Visibility = Visibility.Collapsed; blueRefelction.Visibility = Visibility.Collapsed; } else { reflection = true; redRefelction.Visibility = Visibility.Visible; blueRefelction.Visibility = Visibility.Visible; } } } } UPDATE: I have been testing this some more to try to find out what is causing the issue I am seeing and I believe I found what is causing the issue. Below I have pasted new xaml and code-behind. The new sample below is very similar to the original sample, with a few minor modifications. The xaml basically consists of two stack panels, each containing two borders. The second border in each stack panel is a visual brush (a reflection of the border above it). Now, when I click the "Flip" button, one stack panel gets its ScaleX reduced to zero, while the second stack panel, whose initial ScaleX is zero, gets its ScaleX increased to 1. This animation gives the illusion of flipping. There are also two textblocks which display the scale factor of each stack panel. I added those to try to diagnose my issue. The issue is (as described in the oringal post) that the flipping animation is not smooth. Every time I hit the flip button, the animation starts but whenever the ScaleX factor gets to around .14 to .16, the animation looks like it stalls and the stack panels never have there ScaleX reduced to zero, so they never totally disappear. Now, the strange thing is that if I change the Width/Height properties of the "frontBorder" and "backBorder" borders defined below to use explict values instead of Auto, such as Width=105 and Height=75 (to match the button in the border) everything works fine. The animation stutters the first two or three times I run it but after that the flips are smooth and flawless. (BTW, when an animation is run for the first time, is there something going on in the background, some sort of initialization, that causes it to be a little slow the first time?) Is it possible that the Auto Width/Height of the borders are causing the issue? I can reproduce it everytime but I am not sure why Auto Width/Height would be a problem. Below is the sample. Thanks for the help. <Window x:Class="FlipTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Window.Resources> <Storyboard x:Key="sbFlip"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="front" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.5" Storyboard.TargetName="back" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> <Storyboard x:Key="sbFlipBack"> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="back" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="0"/> </DoubleAnimationUsingKeyFrames> <DoubleAnimationUsingKeyFrames BeginTime="00:00:00.5" Storyboard.TargetName="front" Storyboard.TargetProperty="(UIElement.RenderTransform).(ScaleTransform.ScaleX)"> <SplineDoubleKeyFrame KeyTime="00:00:00.5" Value="1"/> </DoubleAnimationUsingKeyFrames> </Storyboard> </Window.Resources> <Grid x:Name="LayoutRoot" Background="White" ShowGridLines="True"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> <RowDefinition Height="Auto"/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <StackPanel x:Name="front" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform/> </StackPanel.RenderTransform> <Border Name="frontBorder" BorderBrush="Yellow" BorderThickness="2" Width="Auto" Height="Auto"> <Button Margin="0" Name="redButton" Height="75" Background="Red" Width="105" Click="FlipButton_Click"/> </Border> <Border Width="{Binding ElementName=frontBorder, Path=ActualWidth}" Height="{Binding ElementName=frontBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=frontBorder}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <StackPanel x:Name="back" RenderTransformOrigin="0.5,0.5"> <StackPanel.RenderTransform> <ScaleTransform ScaleX="0"/> </StackPanel.RenderTransform> <Border Name="backBorder" BorderBrush="Yellow" BorderThickness="2" Width="Auto" Height="Auto"> <Button Margin="0" Width="105" Background="Blue" Name="blueButton" Height="75" Click="FlipButton_Click"/> </Border> <Border Width="{Binding ElementName=backBorder, Path=ActualWidth}" Height="{Binding ElementName=backBorder, Path=ActualHeight}" Opacity="0.2" BorderBrush="Transparent"> <Border.OpacityMask> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <LinearGradientBrush.GradientStops> <GradientStop Offset="0" Color="Black"/> <GradientStop Offset=".6" Color="Transparent"/> </LinearGradientBrush.GradientStops> </LinearGradientBrush> </Border.OpacityMask> <Border.Background> <VisualBrush Visual="{Binding ElementName=backBorder}"> <VisualBrush.Transform> <ScaleTransform ScaleX="1" ScaleY="-1" CenterX="52.5" CenterY="37.5" /> </VisualBrush.Transform> </VisualBrush> </Border.Background> </Border> </StackPanel> <Button Grid.Row="1" Click="FlipButton_Click" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76">Flip</Button> <TextBlock Grid.Row="2" Grid.Column="0" Foreground="DarkRed" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76" Text="{Binding ElementName=front, Path=(UIElement.RenderTransform).(ScaleTransform.ScaleX)}"/> <TextBlock Grid.Row="3" Grid.Column="0" Foreground="DarkBlue" Height="19.45" HorizontalAlignment="Left" VerticalAlignment="Top" Width="76" Text="{Binding ElementName=back, Path=(UIElement.RenderTransform).(ScaleTransform.ScaleX)}"/> </Grid> </Window> Code-behind: using System;

  • Setting a Visual State from a data bound enum in WPF

    - by firoso
    Hey all, I've got a scenario where I want to switch the visiblity of 4 different content controls. The visual states I have set opacity, and collapsed based on each given state (See code.) What I'd like to do is have the visual state bound to a property of my View Model of type Enum. I tried using DataStateBehavior, but it requires true/false, which doesn't work for me. So I tried DataStateSwitchBehavior, which seems to be totally broken for WPF4 from what I could tell. Is there a better way to be doing this? I'm really open to different approaches if need be, but I'd really like to keep this enum in the equation. Edit: The code shouldn't be too important, I just need to know if there's a well known solution to this problem. <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

  • WPF DataGrid and Avalon TimePicker binding problem

    - by Jorge Vargas
    I'm using a the WPF DataGrid from the wpf toolkit and a TimePicker from AvalonControlsLibrary to insert a collection of TimeSpans. My problem is that bindings are not working inside the DataGrid, and I have no clue of why this isn't working. Here is my setup: I have the following XAML: <Window x:Class="Views.TestMainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:wpf="http://schemas.microsoft.com/wpf/2008/toolkit" xmlns:a="http://schemas.AvalonControls/AvalonControlsLibrary/Controls" SizeToContent="WidthAndHeight" MinHeight="250" MinWidth="300"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <GroupBox Grid.Row="0"> <GroupBox.Header> Testing it: </GroupBox.Header> <wpf:DataGrid ItemsSource="{Binding Path=TestSpans}" AutoGenerateColumns="False"> <wpf:DataGrid.Columns> <wpf:DataGridTemplateColumn Header="Start"> <wpf:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <a:TimePicker SelectedTime="{Binding Path=., Mode=TwoWay}" /> </DataTemplate> </wpf:DataGridTemplateColumn.CellEditingTemplate> <wpf:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding}" /> </DataTemplate> </wpf:DataGridTemplateColumn.CellTemplate> </wpf:DataGridTemplateColumn> </wpf:DataGrid.Columns> </wpf:DataGrid> </GroupBox> <StackPanel Orientation="Horizontal" HorizontalAlignment="Right" Grid.Row="1"> <a:TimePicker SelectedTime="{Binding Path=SelectedTime, Mode=TwoWay}" /> </StackPanel> </Grid> And this is my ViewModel: Imports System.Collections.ObjectModel Namespace ViewModels Public Class TestMainWindowViewModel Private _selectedTime As TimeSpan = DateTime.Now.TimeOfDay Public Property SelectedTime() As TimeSpan Get Return _selectedTime End Get Set(ByVal value As TimeSpan) _selectedTime = value End Set End Property Private _testSpans As ObservableCollection(Of TimeSpan) = New ObservableCollection(Of TimeSpan) Public Property TestSpans() As ObservableCollection(Of TimeSpan) Get Return _testSpans End Get Set(ByVal value As ObservableCollection(Of TimeSpan)) _testSpans = value End Set End Property Public Sub New() _testSpans.Add(DateTime.Now.TimeOfDay) _testSpans.Add(DateTime.Now.TimeOfDay) _testSpans.Add(DateTime.Now.TimeOfDay) End Sub End Class End Namespace I'm starting this window in application.xaml.vb like this: Class Application ' Application-level events, such as Startup, Exit, and DispatcherUnhandledException ' can be handled in this file.

  • How can I load style resources from a dynamically loaded Silverlight application (XAP)?

    - by Tom
    I've followed Tim Heuer's video for dynamically loading other XAP's (into a 'master' Silverlight application), as well as some other links to tweak the loading of resources and am stuck on the particular issue of loading style resources from within the dynamically loaded XAP (i.e. the contents of Assets\Styles.xaml). When I run the master/hosting applcation, it successfully streams the dynamic XAP and I can read the deployment info etc. and load the assembly parts. However, when I actuall try to create an instance of a form from the Dynamic XAP, it fails with Cannot find a Resource with the Name/Key LayoutRootGridStyle which is in it's Assets\Styles.xaml file (it works if I run it directly so I know it's OK). For some reason these don't show up as application resources - not sure if I've totally got the wrong end of the stick, or am just missing something? Code snippet below (apologies it's a bit messy - just trying to get it working first) ... '' # Here's the code that reads the dynamic XAP from the web server ... '' #... wCli = New WebClient AddHandler wCli.OpenReadCompleted, AddressOf OpenXAPCompleted wCli.OpenReadAsync(New Uri("MyTest.xap", UriKind.Relative)) '' #... '' #Here's the sub that's called when openread is completed '' #...

  • WPF: Binding to commands in code behind

    - by sofri
    Hi, I have an WPF Microsoft Surface Applikation and I'm using MVVM-Pattern. I have some buttons that are created in code behind. And I would like to bind commands to them but I only know how that works in the XAML like this: <Custom:SurfaceButton Command="{Binding SaveReservationCommandBinding, Mode=OneWay}"/> But I cannot do it like this because my buttons do not exist in the XAML, only in the code behind. So how would a command binding like that works in code behind?

  • WPF Choppy Animation

    - by Chris Dunaway
    WPF Windows-XP SP3 I'm having a problem with a simple WPF animation. I use the following Xaml code (in XamlPad and also in a WPF project): <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:sys="clr-namespace:System;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" > <Border Name="MyBorder" BorderThickness="10" BorderBrush="Blue" CornerRadius="10" Background="DarkRed" > <Rectangle Name="MyRectangle" Margin="10" StrokeDashArray="2.0,1.0" StrokeThickness="10" RadiusX="10" RadiusY="10" Stroke="Black" StrokeDashOffset="0"> <Rectangle.Triggers> <EventTrigger RoutedEvent="Rectangle.Loaded"> <BeginStoryboard> <Storyboard> <DoubleAnimation Storyboard.TargetName="MyRectangle" Storyboard.TargetProperty="StrokeDashOffset" From="0.0" To="3.0" Duration="0:0:1" RepeatBehavior="Forever" Timeline.DesiredFrameRate="30" /> </Storyboard> </BeginStoryboard> </EventTrigger> </Rectangle.Triggers> </Rectangle> </Border> </Page> It has the effect of causing the border to animate around the rectangle. After a fresh reboot of the machine, this animation is nice and smooth. However, I tend to leave my machine on all the time and after a period time elapses (I don't know how long), the animation starts stuttering and becomes choppy. I thought that it may be memory or resource issues, but after shutting down all other apps and any services that seem unnecessary, the stuttering still continues. However, after a system reboot, the animation is smooth again! I get the same symptoms in a WPF app or in XamlPad. In the case of the app, it doesn't seem to make any difference whether I run in the debugger or if I run the executable directly. I applied the patch at this link: http://support.microsoft.com/kb/981741 and I thought that it had taken care of the issue, but it seems not to have. I have seen some posts that might indicate that using transparency might affect animation, but as you can see, my xaml does not use transparency. Can anyone give me some suggestions on how to determine what the problem is? Are there any WPF diagnostic tools that might help? UPDATE: I have checked my video drivers and they are the latest version. (nVidia GeForce 8400 GS)

  • DoubleAnimation in ScaleTransform

    - by Adam S
    I'm trying, as an exhibition, to use a DoubleAnimation on the ScaleX and ScaleY properties of a ScaleTransform. I have a rectangle (144x144) which I want to make rectangular over five seconds. My XAML: <Window x:Class="ScaleTransformTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300" Loaded="Window_Loaded"> <Grid> <Rectangle Name="rect1" Width="144" Height="144" Fill="Aqua"> <Rectangle.RenderTransform> <ScaleTransform ScaleX="1" ScaleY="1" /> </Rectangle.RenderTransform> </Rectangle> </Grid> </Window> My C#: private void Window_Loaded(object sender, RoutedEventArgs e) { ScaleTransform scaly = new ScaleTransform(1, 1); rect1.RenderTransform = scaly; Duration mytime = new Duration(TimeSpan.FromSeconds(5)); Storyboard sb = new Storyboard(); DoubleAnimation danim1 = new DoubleAnimation(1, 1.5, mytime); DoubleAnimation danim2 = new DoubleAnimation(1, 0.5, mytime); sb.Children.Add(danim1); sb.Children.Add(danim2); Storyboard.SetTarget(danim1, scaly); Storyboard.SetTargetProperty(danim1, new PropertyPath(ScaleTransform.ScaleXProperty)); Storyboard.SetTarget(danim2, scaly); Storyboard.SetTargetProperty(danim2, new PropertyPath(ScaleTransform.ScaleYProperty)); sb.Begin(); } Unfortunately, when I run this program, it does nothing. The rectangle stays at 144x144. If I do away with the animation, and just ScaleTransform scaly = new ScaleTransform(1.5, 0.5); rect1.RenderTransform = scaly; it will elongate it instantly, no problem. There is a problem elsewhere. Any suggestions? I have read the discussion at http://www.eggheadcafe.com/software/aspnet/29220878/how-to-animate-tofrom-an.aspx in which someone seems to have gotten a pure-XAML version working, but the code is not shown there. EDIT: At http://stackoverflow.com/questions/2131797/applying-animated-scaletransform-in-code-problem it seems someone had a very similar problem, I am fine with using his method that worked, but what the heck is that string thePath = "(0).(1)[0].(2)"; all about? What are those numbers representing?

  • Datagrid using usercontrol

    - by klawusel
    Hello I am fighting with this problem: I have a usercontrol which contains a textbox and a button (the button calls some functions to set the textbox's text), here is the xaml: <UserControl x:Class="UcSelect" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Name="Control1Name" <Grid x:Name="grid1" MaxHeight="25"> <Grid.ColumnDefinitions> <ColumnDefinition /> <ColumnDefinition Width="25"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="25"/> </Grid.RowDefinitions> <TextBox x:Name="txSelect" Text="{Binding UcText, Mode=TwoWay}" /> <Button x:Name="pbSelect" Background="Red" Grid.Column="1" Click="pbSelect_Click">...</Button> </Grid> And here the code behind: Partial Public Class UcSelect Private Shared Sub textChangedCallBack(ByVal [property] As DependencyObject, ByVal args As DependencyPropertyChangedEventArgs) Dim UcSelectBox As UcSelect = DirectCast([property], UcSelect) End Sub Public Property UcText() As String Get Return GetValue(UcTextProperty) End Get Set(ByVal value As String) SetValue(UcTextProperty, value) End Set End Property Public Shared ReadOnly UcTextProperty As DependencyProperty = _ DependencyProperty.Register("UcText", _ GetType(String), GetType(UcSelect), _ New FrameworkPropertyMetadata(String.Empty, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, New PropertyChangedCallback(AddressOf textChangedCallBack))) Public Sub New() InitializeComponent() grid1.DataContext = Me End Sub Private Sub pbSelect_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) 'just demo UcText = UcText + "!" End Sub End Class The UserControl works fine when used as a single control in this way: <local:UcSelect Grid.Row="1" x:Name="ucSingle1" UcText="{Binding FirstName, Mode=TwoWay}"/> Now I wanted to use the control in a custom datagrid column. As I like to have binding support I choosed to derive from DataGridtextColumn instead of using a DataGridTemplateColumn, here is the derived column class: Public Class DerivedColumn Inherits DataGridTextColumn Protected Overloads Overrides Function GenerateElement(ByVal oCell As DataGridCell, ByVal oDataItem As Object) As FrameworkElement Dim oElement = MyBase.GenerateElement(oCell, oDataItem) Return oElement End Function Protected Overloads Overrides Function GenerateEditingElement(ByVal oCell As DataGridCell, ByVal oDataItem As Object) As FrameworkElement Dim oUc As New UcSelect Dim oBinding As Binding = CType(Me.Binding, Binding) oUc.SetBinding(UcSelect.UcTextProperty, oBinding) Return oUc End Function End Class The column is used in xaml in the following way: <local:DerivedColumn Header="Usercontrol" Binding="{Binding FirstName, Mode=TwoWay}"></local:DerivedColumn> If I start my program all seems to be fine, but changes I make in the custom column are not reflected in the object (property "FirstName"), the changes are simply rolled back when leaving the cell. I think there must be something wrong with my GenerateEditingElement code, but have no idea ... Any Help would really be appreciated Regards Klaus

  • How to bind DataTable to Chart series?

    - by user175908
    Hello, How to do bind data from DataTable to Chart series? I get null reference exception. I tried binding with square brackets and it did not worked either. So, how to do the binding? Thanks. P.S: I included DataGrid XAML and CS which works just fine. Converting data to List<KeyValuePair<string,int>> works good but it is kinda slow and is unnessesary trash in code.

  • ListBox item doesn't get refresh in WPF?

    - by sanjeev40084
    I have a listbox which has couple of items. When double clicked on each item, the user get option to edit item (text of item). Now once i update the item, my item in listbox doesn't get updated. The first window (one which has listbox) is in MainWindow.xaml file and second window is in EditTaskView.xaml(one which let's edit the items text) file. The code that displays items in lists is: Main.Windows.cs public static ObservableCollection TaskList; public void GetTask() { TaskList = new ObservableCollection<Task> { new Task("Task1"), new Task("Task2"), new Task("Task3"), new Task("Task4") }; lstBxTask.ItemsSource = TaskList; } private void lstBxTask_MouseDoubleClick(object sender, MouseButtonEventArgs e) { var selectedTask = (Task)lstBxTask.SelectedItem; EditTask.txtBxEditedText.Text = selectedTask.Taskname; EditTask.PreviousTaskText = selectedTask.Taskname; EditTask.Visibility = Visibility.Visible; } The xaml code that displays the list: <ListBox x:Name="lstBxTask" Style="{StaticResource ListBoxItems}" MouseDoubleClick="lstBxTask_MouseDoubleClick"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <Rectangle Style="{StaticResource LineBetweenListBox}"/> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Taskname}" Style="{StaticResource TextInListBox}"/> <Button Name="btnDelete" Style="{StaticResource DeleteButton}" Click="btnDelete_Click"/> </StackPanel> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> <ToDoTask:EditTaskView x:Name="EditTask" Grid.Row="1" Grid.RowSpan="2" Grid.ColumnSpan="2" Visibility="Collapsed"/> The Save button in TaskEditView.xaml does this: public string PreviousTaskText { get; set; } private void btnSaveEditedText_Click(object sender, RoutedEventArgs e) { foreach (var t in MainWindow.TaskList) { if (t.Taskname == PreviousTaskText) { t.Taskname = txtBxEditedText.Text; } } Visibility = Visibility.Collapsed; } TaskList is the ObservableCollection, and i though once you update the value the UI gets refreshed. But doesn't seem to work that way. What am i missing?

  • Access Controls in Silverlight DataGrid Column Header from Code

    - by fuzzyman
    We have custom headers in the Silverlight DataGrid using the ContentTemplate. We've got a button in the header and need to programmatically access the button to hook up the event. We're using IronPython, so we can't statically bind the event in the xaml (plus we use the grid for many different views - so we dynamically generate the xaml). How can we get access to controls inside a datagrid column header?

  • Routed Command Question

    - by Andrew
    I'd like to implement a custom command to capture a Backspace key gesture inside of a textbox, but I don't know how. I wrote a test program in order to understand what's going on, but the behaviour of the program is rather confusing. Basically, I just need to be able to handle the Backspace key gesture via wpf commands while keyboard focus is in the textbox, and without disrupting the normal behaviour of the Backspace key within the textbox. Here's the xaml for the main window and the corresponding code-behind, too (note that I created a second command for the Enter key, just to compare its behaviour to that of the Backspace key): <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <TextBox Margin="44,54,44,128" Name="textBox1" /> </Grid> </Window> And here's the corresponding code-behind: using System.Windows; using System.Windows.Input; namespace WpfApplication1 { /// <summary> /// Interaction logic for EntryListView.xaml /// </summary> public partial class Window1 : Window { public static RoutedCommand EnterCommand = new RoutedCommand(); public static RoutedCommand BackspaceCommand = new RoutedCommand(); public Window1() { InitializeComponent(); CommandBinding cb1 = new CommandBinding(EnterCommand, EnterExecuted, EnterCanExecute); CommandBinding cb2 = new CommandBinding(BackspaceCommand, BackspaceExecuted, BackspaceCanExecute); this.CommandBindings.Add(cb1); this.CommandBindings.Add(cb2); KeyGesture kg1 = new KeyGesture(Key.Enter); KeyGesture kg2 = new KeyGesture(Key.Back); InputBinding ib1 = new InputBinding(EnterCommand, kg1); InputBinding ib2 = new InputBinding(BackspaceCommand, kg2); this.InputBindings.Add(ib1); this.InputBindings.Add(ib2); } #region Command Handlers private void EnterCanExecute(object sender, CanExecuteRoutedEventArgs e) { MessageBox.Show("Inside EnterCanExecute Method."); e.CanExecute = true; } private void EnterExecuted(object sender, ExecutedRoutedEventArgs e) { MessageBox.Show("Inside EnterExecuted Method."); e.Handled = true; } private void BackspaceCanExecute(object sender, CanExecuteRoutedEventArgs e) { MessageBox.Show("Inside BackspaceCanExecute Method."); e.Handled = true; } private void BackspaceExecuted(object sender, ExecutedRoutedEventArgs e) { MessageBox.Show("Inside BackspaceExecuted Method."); e.Handled = true; } #endregion Command Handlers } } Any help would be very much appreciated.

    I want to open window2.xaml from the window1.xaml window as an emergent (floating) window. In winforms that was form2.show() , how do I do it in WPF for both WPF application and WPFbrowser application? (I assume it's different for WPF application and WPFbrowser application)

  • How to access a named element of a derived user control in silverlight ?

    - by Mrt
    Hello, I have a custom base user control in silverlight. <UserControl x:Class="Problemo.MyBaseControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <Grid x:Name="LayoutRoot" Background="White"> <Border Name="HeaderControl" Background="Red" /> </Grid> </UserControl> With the following code behind public partial class MyBaseControl : UserControl { public UIElement Header { get; set; } public MyBaseControl() { InitializeComponent(); Loaded += MyBaseControl_Loaded; } void MyBaseControl_Loaded(object sender, RoutedEventArgs e) { HeaderControl.Child = Header; } } I have a derived control. <me:MyBaseControl x:Class="Problemo.MyControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:me="clr-namespace:Problemo" d:DesignHeight="300" d:DesignWidth="400"> <me:MyBaseControl.Header> <TextBlock Name="header" Text="{Binding Text}" /> </me:MyBaseControl.Header> </me:MyBaseControl> With the following code behind. public partial class MyControl : MyBaseControl { public string Text { get; set; } public MyControl(string text) { InitializeComponent(); Text = text; } } I'm trying to set the text value of the header textblock in the derived control. It would be nice to be able to set both ways, i.e. with databinding or in the derived control code behind, but neither work. With the data binding, it doesn't work. If I try in the code behind I get a null reference to 'header'. This is silverlight 4 (not sure if that makes a difference) Any suggestions on how to do with with both databinding and in code ? Cheers
