  • Silverlight DataGrid: Hiding columns using VisualStateManager

    - by Lars Udengaard
    Is it possible to hide a column of a datagrid, without using codebehind? E.g. by using the VisualStateManager? <UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" x:Class="Buttons.MainPage" Width="640" Height="480"> <StackPanel x:Name="LayoutRoot" Width="624" HorizontalAlignment="Right" Margin="0,0,8,0" > <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="EditStates"> <VisualState x:Name="ReadOnly" /> <VisualState x:Name="Edit"> <Storyboard> <ObjectAnimationUsingKeyFrames Storyboard.TargetName="ShownInEditMode" Storyboard.TargetProperty="(UIElement.Visibility)" BeginTime="00:00:00" Duration="00:00:00.0010000"> <DiscreteObjectKeyFrame KeyTime="00:00:00"> <DiscreteObjectKeyFrame.Value> <Visibility>Visible</Visibility> </DiscreteObjectKeyFrame.Value> </DiscreteObjectKeyFrame> </ObjectAnimationUsingKeyFrames> </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <data:DataGrid AutoGenerateColumns="False" ItemsSource="{Binding BBRNumbers}"> <data:DataGrid.Columns> <data:DataGridTextColumn Header="AlwaysShown" Width="80" Binding="{Binding Municipality}" /> <data:DataGridTextColumn Header="ShownInEditMode" Width="73" Binding="{Binding Estate}" Visibility="Collapsed" /> </data:DataGrid.Columns> </data:DataGrid> </StackPanel> Calling the following should then hide the column, but this doesnt work. VisualStateManager.GoToState(this, "Edit", false); Any ideas?

  • Using LibraryStacks in a ScatterView on Surface

    - by HappyCodeMonkey
    We're trying to figure out how to drag an item from a LibraryStack container onto a ScatterView, like how the photo viewer sample applications work. Currently, the item just flies back into the LibraryStack after we drag it out. We can drag and drop items into other LibraryStacks or LibraryBars. Here's a sample of what we're trying: <s:SurfaceWindow x:Class="Idia_seminar.SurfaceWindow1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:s="http://schemas.microsoft.com/surface/2008" Title="Idia_seminar" > <s:SurfaceWindow.Resources> <ImageBrush x:Key="WindowBackground" Stretch="None" Opacity="0.6" ImageSource="pack://application:,,,/Resources/WindowBackground.jpg"/> </s:SurfaceWindow.Resources> <Grid Background="{StaticResource WindowBackground}" > <s:ScatterView Name="scatterView1" AllowDrop="True"> <s:SurfaceButton Name="surfaceButton1">Button</s:SurfaceButton> <s:LibraryStack AllowDrop="True"> <s:LibraryStackItem Content="hello"></s:LibraryStackItem> </s:LibraryStack> </s:ScatterView> </Grid> </s:SurfaceWindow> Thanks!

  • WPF 4.0 Custom panel won't show dynamically added controls in VS 2010 Designer

    - by Matt Ruwe
    I have a custom panel control that I'm trying to dynamically add controls within. When I run the application the static and dynamically added controls show up perfectly, but the dynamic controls do not appear within the visual studio designer.

  • Binding "Text-Property" of a derived textbox to another textbox doesn´t work

    - by Jehof
    Hello, i have a class 'MyTextBox' that derives from the default TextBox in Silverlight. This class currently contains no additional code. I set up a binding in xaml to bind the Text-Property of MyTextbox to another Textbox to reflect the input made in the Textbox. The effect is that MyTextBox doesn´t update and not display the text of the other Textbox. Additional i made an equal binding for a normal Textbox. And this works. Here´s the XAML for the bindings. <UserControl x:Class="Silverlight.Sample.Dummy" 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" xmlns:my="clr-namespace:Sample" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400"> <StackPanel x:Name="LayoutRoot" Background="White"> <TextBox Height="23" x:Name="textBox2" Width="120" /> <TextBox Text="{Binding ElementName=textBox2, Path=Text, Mode=TwoWay}" Width="120" /> <my:NumberTextBox Width="120" Text="{Binding ElementName=textBox2, Path=Text, Mode=OneWay}" /> </StackPanel> Is there something special to set for binding, when i derive from a control. PS: I tried a binding to a dummy object with INotifyPropertyChanged and set it as DataContext for the existing Textboxes. This test works as expected and my derived textbox gets updated.

  • WPF Databinding CheckBox.IsChecked

    How would I bind the IsChecked member of a CheckBox to a member variable in my form? (I realize I can access it directly, but I am trying to learn about databinding and WPF) Below is my failed attempt to get this working. XAML: <Window x:Class="MyProject.Form1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Title" Height="386" Width="563" WindowStyle="SingleBorderWindow"> <Grid> <CheckBox Name="checkBoxShowPending" TabIndex="2" Margin="0,12,30,0" Checked="checkBoxShowPending_CheckedChanged" Height="17" VerticalAlignment="Top" HorizontalAlignment="Right" Width="92" Content="Show Pending" IsChecked="{Binding ShowPending}"> </CheckBox> </Grid> </Window> Code: namespace MyProject { public partial class Form1 : Window { private ListViewColumnSorter lvwColumnSorter; public bool?

  • Unknown Build Error using WPF Toolkit

    - by Tom Allen
    I installed the Feb 2010 WPF Toolkit as I'm interested in evaluating the AutoCompleteBox control and I'm having extremely limited success. I can get the control to work, but as soon as I try and set any of it's properties in XAML, I get the following: Unknown build error, 'Cannot resolve dependency to assembly 'WPFToolkit, Version=3.5.40128.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event. I've been testing this on a blank WPF window in a new solution. I'm guessing I'm just missing a reference or something... Here's the XAML (I've added nothing to the .xaml.cs): <Window x:Class="WpfToolkitApplication.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:toolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit" Title="Window1" Height="300" Width="300"> <Grid> <toolkit:AutoCompleteBox Height="25"/> </Grid> </Window> The only reference I've added is System.Windows.Controls.Input.Toolkit. Any ideas?

  • How do I solve column width problems in a SSRS Tablix?

    - by David Stein
    I'm creating a simple report from Microsoft Dynamics CRM. When I pull in the following dataset: SELECT FQD.productidname , FQD.NEW_PRICEBREAKS , FQD.NEW_WEEKSARO , ltrim(rtrim(FP.NEW_PRODUCTNAME)) AS NewProductDesc , FQD.productdescription , FQD.quoteid , FQD.quantity , FQD.productiddsc , FQD.baseamount , FQD.lineitemnumber , FQD.priceperunit , FQD.extendedamount , ISNULL(FP.productnumber, '') AS productnumber , ISNULL(FQD.uomidname, '-') AS Unit , FQD.tax AS Tax , FQD.volumediscountamount * FQD.quantity AS Discount , FQD.manualdiscountamount AS MDiscount , FQD.quotedetailid , FQD.crm_moneyformatstring , FQD.NEW_PRICEPERUNIT , FQD.NEW_PRICEPERUNIT_BASE FROM FilteredQuoteDetail FQD LEFT OUTER JOIN FilteredProduct FP ON FQD.productid = FP.productid WHERE (FQD.quoteid = @CRM_QuoteId) The NewProductDesc field is too wide. If I shorted it in design view, it still comes out too wide in the presentation. I think the field is coming out that wide because the database field probably has a bunch of blank spaces at the end of every description. I could not find a way to force that field in the Tablix not to grow horizontally, so I attempted to remedy it in the dataset by replacing the NewProductDesc line with: ltrim(rtrim(FP.NEW_PRODUCTNAME)) AS NewProductDesc However, that has no effect either. Can anyone suggest why this behavior is occuring? Can anyone tell me how I can force the field not to grow horizontally?

  • Split WPF Style XAML Files

    - by anon
    Most WPF styles I have seen are split up into one very long Theme.xaml file. I want to split mine up for readability so my Theme.xaml looks like this: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/PresentationFramework.Aero;v3.0.0.0;31bf3856ad364e35;component/themes/aero.normalcolor.xaml"/> <ResourceDictionary Source="Controls/Brushes.xaml"/> <ResourceDictionary Source="Controls/Buttons.xaml"/> ... </ResourceDictionary.MergedDictionaries> </ResourceDictionary> The problem is that this solution does not work. I have a default button style which is BasedOn the default Aero style for a button: <Style x:Key="{x:Type Button}" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}"> <Setter Property="FontSize" Value="14"/> ... </Style> If I place all of this in one file it works but as soon as I split it up I get StackOverflow exceptions because it thinks it is BasedOn itself. Is there a way around this? How does WPF add resources when merging resource dictionaries?

  • Blend "Window is not supported in a WPF Project"

    - by Andy Dent
    I am having a frustrating time with Blend reporting "Window is not supported in a Windows Presentation Foundation (WPF) project." due to unbuildable configurations but can't quite work out how to mangle my way out of it. I've worked out it is probably due to my trying to have a single solution with x86 and x64 configurations. There is no way to tell Blend 2 which is the active Solution Configuration and active Solution Platform. I think it's a bit of a weakness in the configuration system, or maybe the way I've set things up, but I have Debug64 and Debug solution configurations one of each is used with the platform x86 and x64. I also think it's a simple sorting problem - x64 comes before x86 and Debug comes before Debug64 so Blend ends up with an unbuildable config of Debug with x64. When I choose the combination of Debug and x64 in VS, its XAML editor can't load either. The solution is a moderately complex one - there's a pure Win32 DLL, C++/CLI Model project and two other WPF assemblies used by the main WPF project. UPDATE I have ripped all the x64 config out of my solution and rebuilt everything with no effect. I then uninstalled Blend 2 and installed Blend 3 - it doesn't like things either. The Visual Studio XAML editor is still very happy as is the program building and running. (echoes of strangled scream of frustration from oz)

  • How do I make an ellipse blink?

    - by MedicineMan
    I am trying to make a custom control in WPF. I want it to simulate the behavior of a LED that can blink. There are three states to the control: On, Off, and Blinking. I know how to set On and Off through the code behind, but this WPF animation stuff is just driving me nuts!!!! I cannot get anything to animate whatsoever. The plan is to have a property called state. When the user sets the value to blinking, I want the control to alternate between green and grey. I'm assuming I need a dependency property here, but have no idea. I had more xaml before but just erased it all. it doesn't seem to do anything. I'd love to do this in the most best practice way possible, but at this point, I'll take anything. I'm half way to writing a thread that changes the color manually at this point. <UserControl x:Class="WpfAnimation.LED" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <Grid> <Ellipse x:Name="MyLight" Height="Auto" Width="Auto"/> </Grid> </UserControl>

  • [WPF] ComboBox.Text not taking the ItemStringFormat property into account

    - by Thomas Levesque
    I just noticed a strange behavior which looks like a bug. Consider the following XAML : <Page xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:sys="clr-namespace:System;assembly=mscorlib"> <Page.Resources> <x:Array x:Key="data" Type="{x:Type sys:String}"> <sys:String>Foo</sys:String> <sys:String>Bar</sys:String> <sys:String>Baz</sys:String> </x:Array> </Page.Resources> <StackPanel Orientation="Vertical"> <Button>Boo</Button> <ComboBox Name="combo" ItemsSource="{Binding Source={StaticResource data}}" ItemStringFormat="##{0}##" /> <TextBlock Text="{Binding Text, ElementName=combo}"/> </StackPanel> </Page> The ComboBox displays the values as "##Foo##", "##Bar##" and "##Baz##". But the TextBlock displays the selected values as "Foo", "Bar" and "Baz". So the ItemStringFormat is apparently ignored for the Text property... Is that a bug ? If it is, is there a workaround ? Or am I just doing something wrong ?

  • Handle exceptions with WPF and MVVM

    - by Jon Cahill
    I am attempting to build an application using WPF and the MVVM pattern. I have my Views being populated from my ViewModel purely through databinding. I want to have a central place to handle all exceptions which occur in my application so I can notify the user and log the error appropriately. I know about Dispatcher.UnhandledException but this does not do the job as exception that occur during databinding are logged to the output windows. Because my View is databound to my ViewModel the entire application is pretty much controlled via databinding so I have no way to log my errors. Is there a way to generically handle the exceptions raised during databinding, without having to put try blocks around all my ViewModel public's? Example View: <Window x:Class="Test.TestView" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="TestView" Height="600" Width="800" WindowStartupLocation="CenterScreen"> <Window.Resources> <BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter" /> </Window.Resources> <StackPanel VerticalAlignment="Center"> <Label Visibility="{Binding DisplayLabel, Converter={StaticResource BooleanToVisibilityConverter}}">My Label</Label> </StackPanel> </Window> The ViewModel: public class TestViewModel { public bool DisplayLabel { get { throw new NotImplementedException(); } } } It is an internal application so I do not want to use Wer as I have seen previously recommended.

  • ASP.net DAL DatasSet and Table Adapter not in namespace - Northwind Tutorial

    - by Alan
    I've been attempting to walk through the "Creating a Data Access Layer" tutorial found http://www.asp.net/learn/data-access/tutorial-01-cs.aspx I create the DB connection, create the typed dataset and table adapter, specify the sql, etc. When I add the code to the presentation layer (in this case a page called AllProducts.aspx) I am unable to find the NorthwindTableAdapters.ProductsTableAdapter class. I tried to import the NorthwindTableAdapters namespace, but it is not showing up. Looking in the solution explorer Class View confirms that there is a Northwind class, but not the namespace I'm looking for. I've tried several online tutorials that all have essentially the same steps, and I'm getting the same results. Can anyone give me a push in the right direction? I'm getting error: Namespace or type specified in the Imports 'NorthwindTableAdapters' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. I think I might need to add a reference OR they may be creating a separate class and importing it into their main project. If that's the case, the tutorials do not mention this.

  • WPF Constrain the resize of a canvas' child object to the dimensions of the canvas

    Given the following XAML: <Window x:Class="AdornerTesting.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="500" Width="500" Loaded="Window_Loaded"> <Grid Name="grid"> <Canvas Name="canvas" Width="400" Height="400" Background="LightGoldenrodYellow"> <RichTextBox Name="richTextBox" Canvas.Top="10" Canvas.Left="10" BorderBrush="Black" BorderThickness="2" Width="200" Height="200" MaxWidth="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Canvas}},Path=ActualWidth}" MaxHeight="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Canvas}},Path=ActualHeight}"/> </Canvas> </Grid> </Window> and a set of adorners being added to the RichTextBox in the Loaded event like so: AdornerLayer adornerLayer = AdornerLayer.GetAdornerLayer(richTextBox); adornerLayer.Add(new ResizeAdorner(richTextBox)); How do I keep from being able to resize the RichTextBox beyond the visble bounds of the Canvas? The ResizeAdorner is essentially the same code that can be found in the MSDN adorner example and it works just fine. Should I be doing something with the bindings of MaxWidth and MaxHeight in the code-behind to calculate how the RichTextBox can be resized? Or is there a way to do this in XAML?

    Hi, I'm trying to figure out how to do something similar to the twitter silverlight app that Scott Guthrie demoed recently in WPF: http://weblogs.asp.net/scottgu/archive/2010/03/18/building-a-windows-phone-7-twitter-application-using-silverlight.aspx Unfortunately, I seem to be having a hard time understanding the wpf layout system in some fundamental way. I've been trying various combinations of horizontalalignment/stretch, width/auto at different levels in the hierarchy, and I can't seem to get the "message" textblock to wrap without assigning an explicit width. All I want is for the text to wrap based on the width of the window (or whatever is the parent container). <Window x:Class="TweeterWin.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"> <ScrollViewer Height="auto" > <ListBox Name="tweetList" Height="auto" > <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal" Height="132"> <Image Source="{Binding Avatar}" Height="73" Width="73" VerticalAlignment="Top" Margin="0,10,8,0"/> <StackPanel > <TextBlock Text="{Binding User}" TextWrapping="Wrap" Foreground="#FFC8AB14" FontSize="15" /> <TextBlock Text="{Binding Message}" TextWrapping="Wrap" FontSize="10" /> </StackPanel> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </ScrollViewer> </Window> As a follow up, if anyone can send any links my way that might help me understand some of these layout fundamentals. I think I understand the main layout options (canvas, grid, stackpanel, etc.), but I dont' understand why I can't get this textblock to wrap in this scenario. Thanks!

  • WPF DatePicker IsEnabled property not changing appearance

    - by Jonathan
    I think I have found an issue with the DatePicker in the toolkit, perhaps some of you gurus can check it out. The issue is when setting the IsEnabled property of the DatePicker. If set in XAML, it stays grey even if you set the IsEnabled to true at run time. The same goes for the other way around should it start off being enabled. The button just changes the IsEnabled property of the date picker, you will see that when it becomes enabled, the style remains grayed out. <Window x:Class="WpfApplication3.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:tk="http://schemas.microsoft.com/wpf/2008/toolkit" Title="Window1" Height="300" Width="300"> <StackPanel> <tk:DatePicker x:Name="txtDate" IsEnabled="False"></tk:DatePicker> <Button Height="25" Click="Button_Click"></Button> </StackPanel> </Window> private void Button_Click(object sender, RoutedEventArgs e) { txtDate.IsEnabled = !txtDate.IsEnabled; }

  • CSS positioning is weird when reducing the viewport

    - by Lars Hanke
    I have a little meditation for you ... I run a site using a liquid tri-col layout with a header. The layout runs nicely since more than a decade with all browsers I ever dared to try. It is based on absolute positioning in CSS. This page provides an example of the actual site. Watching the page from my tablet I found that the right column overlaps the center matter. Further investigation using Firebug showed that once the center content reaches 360px width, the right margin of the div shrinks. Why is that? Since Firefox and Android render the same, I guess that this is something, which is actually supposed to be. However, I tried to make virtue out of necessity and experimented setting min-width for body and content and made the body scroll overflow. The body actually scrolls, but the right column is positioned on the right edge of the viewport instead of the body element (Firefox). Is this intentional CSS standard? Any ideas how to solve the presentation on small displays? Thanks for your efforts,  – lars.

  • Windows Forms Host + System.Windows.Forms.DataVisualization.Chart

    - by dark-elf2
    Good day all I have the following question: I would like to use Chart from Windows Forms due to the fact that it allows to build much more types of graphical visualisation that one from WPF Toolkit does. So, I am adding Chart control for Windows Forms as a child element into the WindowsFormsHost. But, when I run the application I and all my clients see only white area. Though, any other Windows Forms Control works great in Windows Forms Host. What is wrong with the Chart control? Here is the XAML code <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:wfi="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration" xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms" xmlns:CHR="clr-namespace:System.Windows.Forms.DataVisualization.Charting;assembly=System.Windows.Forms.DataVisualization" Title="Window1" Height="300" Width="300"> <Grid> <wfi:WindowsFormsHost x:Name="mainFGrid" > <CHR:Chart x:Name="mainChart" /> </wfi:WindowsFormsHost> </Grid> </Window> Kind regards, Anatoliy Sova

  • wpf datagrid current item binding

    - by tk
    I want to bind a content of Label to the selected item of a datagrid. I thought the 'current item' binding expression would work, but it is not. My xaml code and code-behind c# is like below. <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="512" Width="847"> <DockPanel LastChildFill="True"> <Label Content="{Binding Data/colA}" DockPanel.Dock="Top" Height="30"/> <DataGrid ItemsSource="{Binding Data}"></DataGrid> </DockPanel> </Window> namespace WpfApplication2 { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); this.DataContext = new MyData(); } } public class MyData { DataTable data; public MyData() { data = new DataTable(); data.Columns.Add("colA"); data.Columns.Add("colB"); data.Rows.Add("aa", 1); data.Rows.Add("bb", 2); } public DataTable Data { get { return data; } } } } The label shows the first item of the DataTable, and does not change when i select other items on the datagrid. It seems the current item of dataview does not change. What should i do to bind it to the current selected item of datagrid?
