  • WPF - simple relative path - FindAncestor

    - by user309392
    In the XAML below the ToolTip correctly binds to RelativeSource Self. However, I can't for the life of me work out how to get the TextBlock in the commented block to refer to SelectedItem.Description <Controls:RadComboBoxWithCommand x:Name="cmbPacking" Grid.Row="2" Grid.Column="5" ItemsSource="{Binding PackingComboSource}" DisplayMemberPath="DisplayMember" SelectedValuePath="SelectedValue" SelectedValue="{Binding ElementName=dataGrid1, Path=SelectedItem.PackingID}" ToolTip="{Binding RelativeSource={RelativeSource Self}, Path=SelectedItem.Description}" IsSynchronizedWithCurrentItem="True" Style="{StaticResource comboBox}"> <!-- <Controls:RadComboBoxWithCommand.ToolTip>--> <!-- <TextBlock Text="{Binding RelativeSource={RelativeSource Self}, Path=SelectedItem.Description}" TextWrapping="Wrap" Width="50"/>--> <!-- </Controls:RadComboBoxWithCommand.ToolTip>--> </Controls:RadComboBoxWithCommand> I would appreciate any suggestions Thanks - Jeremy

  • Wpf: Storyboard.TargetName works, but Setter TargetName doesn't.

    - by MainMa
    Hi, Let's say we have a XAML code like this: <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type ListBoxItem}"> <Border HorizontalAlignment="Center" VerticalAlignment="Center"> <Border.LayoutTransform> <!--We are rotating randomly each image. Selected one will be rotated to 45°.--> <RotateTransform Angle="{Binding RandomAngle}" x:Name="globalRotation"/> </Border.LayoutTransform> <Grid> <Image Source="{Binding ImageLocation}" Stretch="None" /> <TextBlock x:Name="title" Text="{Binding Title}" /> </Grid> </Border> <ControlTemplate.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter TargetName="title" Property="Visibility" Value="Visible"/> <!--The next line will not compile.--> <Setter TargetName="globalRotation" Property="Angle" Value="45"/> <Trigger.EnterActions> <BeginStoryboard> <Storyboard> <!--This compiles well.--> <DoubleAnimation Storyboard.TargetName="globalRotation" Storyboard.TargetProperty="Angle" To="45" Duration="00:00:03"/> </Storyboard> </BeginStoryboard> </Trigger.EnterActions> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> This code is intended to display a set of images in a listbox. Each image has a random rotation, but when selected, rotates to 45 degrees. Rotating selected image through a storyboard works well. I just specify Storyboard.TargetName and it rotates the image when selected (Trigger.ExitActions is omitted to make the code shorter). Now, if I want, instead of using a storyboard, assign 45 degrees value directly, I can't do that, because <Setter TargetName="globalRotation" Property="Angle" Value="45"/>: it compiles with "Cannot find the Trigger target 'globalRotation'. (The target must appear before any Setters, Triggers, or Conditions that use it.)" error. What happens? I suppose that Storyboard.TargetName is evaluated during runtime, so let me compile it. Is it right? How to make it work with just a setter, without using a storyboard?

  • WPF Focus In Tab Control Content When New Tab is Created

    - by Phil Sandler
    I've done a lot of searching on SO and google around this problem, but can't seem to find anything else to try. I have a MainView (window) that contains a tab control. The tab control binds to an ObservableCollection of ChildViews (user controls). The MainView's ViewModel has a method that allows adding to the collection of ChildViews, which then creates a new tab. When a new tab is created, it becomes the active tab, and this works fine. This method on the MainView is called from another ViewModel (OtherViewModel). What I am trying to do is set the keyboard focus to the first control on the tab (an AutoCompleteBox from WPFToolkit*) when a new tab is created. I also need to set the focus the same way, but WITHOUT creating a new tab (so set the focus on the currently active tab). (*Note that there seem to be some focus problems with the AutoCompleteBox--even if it does have focus you need to send a MoveNext() to it to get the cursor in its window. I have worked around this already). So here's the problem. The focusing works when I don't create a new tab, but it doesn't work when I do create a new tab. Both functions use the same method to set focus, but the create logic first calls the method that creates a new tab and sets it to active. Code that sets the focus (in the ChildView's Codebehind): IInputElement element1 = Keyboard.Focus(autoCompleteBox); //plus code to deal with AutoCompleteBox as noted. In either case, the Keyboard.FocusedElement starts out as the MainView. After a create, calling Keyboard.Focus seems to do nothing (focused element is still the MainView). Calling this without creating a tab correctly sets the keyboard focus to autoCompleteBox. Any ideas? Update: Bender's suggestion half-worked. So now in both cases, the focused element is correctly the AutoCompleteBox. What I then do is MoveNext(), which sets the focus to a TextBox. I have been assuming that this Textbox is internal to the AutoCompleteBox, as the focus was correctly set on screen when this happened. Now I'm not so sure. This is still the behavior I see when this code gets hit when NOT doing a create. After a create, MoveNext() sets the focus to an element back in my MainView. The problem must still be along the lines of Bender's answer, where the state of the controls is not the same depending on whether a new tab was created or not. Any other thoughts?

  • WPF - Only want one expander open at a time in grouped Listbox

    - by Portsmouth
    I have a UserControl with a templated grouped listbox with expanders and only want one expander open at any time. I have browsed through the site but haven't found anything except binding the IsExpanded to IsSelected which isn't quite what I want. I am trying to put some code in the Expanded event that would loop through Expanders and close all the ones that aren't the expander passed in the Expanded event. I can't seem to figure out how to get at them. I've tried ListBox.Items.Groups but didn't see how to get at them and tried ListBox.ItemContainerGenerator.ContainerFromItem (or Index) but nothing came back. Thanks <ListBox Name="ListBox"> <ListBox.GroupStyle> <GroupStyle> <GroupStyle.ContainerStyle> <Style TargetType="{x:Type GroupItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type GroupItem}"> <Border BorderBrush="CadetBlue" BorderThickness="1"> <Expander BorderThickness="0,0,0,1" Expanded="Expander_Expanded" Focusable="False" IsExpanded="{Binding IsSelected, RelativeSource={RelativeSource FindAncestor, AncestorType= {x:Type ListBoxItem}}}" > <Expander.Header> <Grid> <StackPanel Height="30" Orientation="Horizontal"> <TextBlock Foreground="Navy" FontWeight="Bold" Text="{Binding Path=Name}" Margin="5,0,0,0" MinWidth="200" Padding="3" VerticalAlignment="Center" /> <TextBlock Foreground="Navy" FontWeight="Bold" Text=" Setups: " VerticalAlignment="Center" HorizontalAlignment="Right"/> <TextBlock Foreground="Navy" FontWeight="Bold" Text="{Binding Path=ItemCount}" VerticalAlignment="Center" HorizontalAlignment="Right" /> </StackPanel> </Grid> </Expander.Header> <Expander.Content> <Grid Background="white" > <ItemsPresenter /> </Grid> </Expander.Content> <Expander.Style > <Style TargetType="{x:Type Expander}"> <Style.Triggers> <Trigger Property="IsMouseOver" Value="true"> <Setter Property="Background"> <Setter.Value> <LinearGradientBrush StartPoint="0,0" EndPoint="0,1"> <GradientStop Color="WhiteSmoke" Offset="0.0" /> <GradientStop Color="Orange" Offset="1.0" /> </LinearGradientBrush> </Setter.Value> </Setter> </Trigger> <Trigger Property="IsMouseOver" Value="false" <Setter Property="Background"> <Setter.Value>

  • Query on MVVM design pattern on WPF.

    - by Ashish Ashu
    I am using MVVM architecture. I have a usercontrol UC as a View Model is a ModelData class ViewModel (UCViewModel) is binded to a usercontrol. I have three more usercontrols that is inside the usercontrol UC ( discussed above). Let's say uc1, uc2 and uc3. and the visibility of uc1 , uc2 and uc3 inside UC depends on the type selected ( which ever radio button is selected ). Since UC is binded to UCViewModel and I have to do all the stuff related to uc1 , uc2 and uc3 inside UCViewModel. Can I have seperate VM to uc1 , uc2 and uc3.. if Yes how can i do that ? Please Help!!

  • WPF combobox loses Aero theme when using a style trigger

    - by Greg R
    I am using style triggers to change combo box to texbox if it's readonly, but for some reason when I apply the style, it cause the combobox theme to change from Aero to Windows Classic (the theme I currently have in use on my PC). Can I avoid this somehow? Here is my code: <ComboBox ItemsSource="{Binding Source={StaticResource AllCountries}}" SelectedValue="{Binding OrderInfoVm.BillingCountry}" DisplayMemberPath="Value" SelectedValuePath="Key" IsReadOnly="{Binding ReadOnlyMode}" Style="{StaticResource EditableDropDown}" /> <Style x:Key="EditableDropDown" TargetType="ComboBox"> <Style.Triggers> <Trigger Property="IsReadOnly" Value="True"> <Setter Property="SelectedValuePath" Value="Content" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ComboBox"> <TextBox Text="{TemplateBinding SelectedValue, Converter={StaticResource StringCaseConverter}}" BorderThickness="0" Background="Transparent" FontSize="{TemplateBinding FontSize}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" FontFamily="{TemplateBinding FontFamily}" Width="{TemplateBinding Width}" TextWrapping="Wrap"/> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style>

  • WPF ComboBox Binding to non string object

    - by Mike L
    I'm using MVVM (MVVM Light Toolkit) and have a property on the view model which exposes a list of objects. The objects contain two properties, both strings, which correlate to an abbreviation and a description. I want the ComboBox to expose the pairing as "abbreviation - description". If I use a data template, it does this easily. I have another property on the view model which represents the object that should display as selected -- the chosen item in the ComboBox. I'm binding the ItemsSource to the list, as it represents the universe of available selections, and am trying to bind the SelectedItem to this object. I'm killing myself trying to figure out why I can't get it to work, and feeling more like a fraud by the hour. In trying to learn why this works, I created the same approach with just a list of strings, and a selected string. This works perfectly. So, it clearly has something to do with the typing... perhaps something in choosing equality? Or perhaps it has to do with the data template? Here is the XAML: <Window x:Class="MvvmLight1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="300" Width="300" DataContext="{Binding Main, Source={StaticResource Locator}}"> <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Skins/MainSkin.xaml" /> </ResourceDictionary.MergedDictionaries> <DataTemplate x:Key="DataTemplate1"> <StackPanel Orientation="Horizontal"> <TextBlock TextWrapping="Wrap" Text="{Binding CourtCode}"/> <TextBlock TextWrapping="Wrap" Text=" - "/> <TextBlock TextWrapping="Wrap" Text="{Binding CourtDescription}"/> </StackPanel> </DataTemplate> </ResourceDictionary> </Window.Resources> <Grid x:Name="LayoutRoot"> <ComboBox x:Name="cmbAbbrevDescriptions" Height="35" Margin="25,75,25,25" VerticalAlignment="Top" ItemsSource="{Binding Codes}" ItemTemplate="{DynamicResource DataTemplate1}" SelectedItem="{Binding selectedCode}" /> <ComboBox x:Name="cmbStrings" Height="35" Margin="25" VerticalAlignment="Top" ItemsSource="{Binding strs}" SelectedItem="{Binding selectedStr}"/> </Grid> </Window> And, if helpful, here is the ViewModel: using GalaSoft.MvvmLight; using MvvmLight1.Model; using System.Collections.Generic; namespace MvvmLight1.ViewModel { public class MainViewModel : ViewModelBase { public const string CodesPropertyName = "Codes"; private List<Court> _codes = null; public List<Court> Codes { get { return _codes; } set { if (_codes == value) { return; } var oldValue = _codes; _codes = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(CodesPropertyName, oldValue, value, true); } } public const string selectedCodePropertyName = "selectedCode"; private Court _selectedCode = null; public Court selectedCode { get { return _selectedCode; } set { if (_selectedCode == value) { return; } var oldValue = _selectedCode; _selectedCode = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(selectedCodePropertyName, oldValue, value, true); } } public const string strsPropertyName = "strs"; private List<string> _strs = null; public List<string> strs { get { return _strs; } set { if (_strs == value) { return; } var oldValue = _strs; _strs = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(strsPropertyName, oldValue, value, true); } } public const string selectedStrPropertyName = "selectedStr"; private string _selectedStr = ""; public string selectedStr { get { return _selectedStr; } set { if (_selectedStr == value) { return; } var oldValue = _selectedStr; _selectedStr = value; // Update bindings and broadcast change using GalaSoft.Utility.Messenging RaisePropertyChanged(selectedStrPropertyName, oldValue, value, true); } } /// <summary> /// Initializes a new instance of the MainViewModel class. /// </summary> public MainViewModel() { Codes = new List<Court>(); Court code1 = new Court(); code1.CourtCode = "ABC"; code1.CourtDescription = "A Court"; Court code2 = new Court(); code2.CourtCode = "DEF"; code2.CourtDescription = "Second Court"; Codes.Add(code1); Codes.Add(code2); Court code3 = new Court(); code3.CourtCode = "DEF"; code3.CourtDescription = "Second Court"; selectedCode = code3; selectedStr = "Hello"; strs = new List<string>(); strs.Add("Goodbye"); strs.Add("Hello"); strs.Add("Ciao"); } } } And here is the ridiculously trivial class that is being exposed: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace MvvmLight1.Model { public class Court { public string CourtCode { get; set; } public string CourtDescription { get; set; } } } Thanks!

  • WPF: ContentPresenter changing Foreground unexpectedly depending on where styles are located

    - by VLTII
    Hi, I'm having an issue with the ContentPresenter behaving unexpectedly based on whether the styles are located in the Window.Resources or in a ResourceDictionary. Specifically, I'm setting the Foreground of the default TextBlock to Black, then setting the Foreground value in my default button style to White. If the styles exits on the page like this, they work fine: <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero" x:Class="TestBed.MainWindow" x:Name="Window" Title="MainWindow" Width="640" Height="480"> <Window.Resources> <Style TargetType="{x:Type TextBlock}"> <Setter Property="Foreground" Value="Black" /> </Style> <Style x:Key="ButtonFocusVisual"> <Setter Property="Control.Template"> <Setter.Value> <ControlTemplate> <Rectangle Stroke="Black" StrokeDashArray="1 2" StrokeThickness="1" Margin="2" SnapsToDevicePixels="true"/> </ControlTemplate> </Setter.Value> </Setter> </Style> <LinearGradientBrush x:Key="ButtonNormalBackground" EndPoint="0,1" StartPoint="0,0"> <GradientStop Color="#F3F3F3" Offset="0"/> <GradientStop Color="#EBEBEB" Offset="0.5"/> <GradientStop Color="#DDDDDD" Offset="0.5"/> <GradientStop Color="#CDCDCD" Offset="1"/> </LinearGradientBrush> <SolidColorBrush x:Key="ButtonNormalBorder" Color="#FF707070"/> <Style TargetType="{x:Type Button}"> <Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}"/> <Setter Property="Background" Value="{StaticResource ButtonNormalBackground}"/> <Setter Property="BorderBrush" Value="{StaticResource ButtonNormalBorder}"/> <Setter Property="BorderThickness" Value="1"/> <Setter Property="Foreground" Value="White"/> <Setter Property="HorizontalContentAlignment" Value="Center"/> <Setter Property="VerticalContentAlignment" Value="Center"/> <Setter Property="Padding" Value="1"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Button}"> <Microsoft_Windows_Themes:ButtonChrome x:Name="Chrome" SnapsToDevicePixels="true" Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" RenderDefaulted="{TemplateBinding IsDefaulted}" RenderMouseOver="{TemplateBinding IsMouseOver}" RenderPressed="{TemplateBinding IsPressed}"> <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" RecognizesAccessKey="True"/> </Microsoft_Windows_Themes:ButtonChrome> <ControlTemplate.Triggers> <Trigger Property="IsKeyboardFocused" Value="true"> <Setter Property="RenderDefaulted" TargetName="Chrome" Value="true"/> </Trigger> <Trigger Property="ToggleButton.IsChecked" Value="true"> <Setter Property="RenderPressed" TargetName="Chrome" Value="true"/> </Trigger> <Trigger Property="IsEnabled" Value="false"> <Setter Property="Foreground" Value="#ADADAD"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> </Window.Resources> <StackPanel x:Name="LayoutRoot"> <Button Content="Button" /> </StackPanel> </Window> But if I move those same styles over to a ResourceDictionary, the Foreground of the button switches to black.

  • WPF DataGrid : CanContentScroll property causing odd behavior

    - by Sonic Soul
    i have a solution where i generate a DataGrid (or multiple instances) based on user criteria.. each grid keeps receiving data as it comes in via ObservableCollection the problem i had, was that the scroll acted weird. It was choppy, and scrollbar would resize it self while scrolling. than i found.. CanContentScroll property! It completely fixes the weird scrolling behavior bringing me temporary bliss and happiness. however, it causes 2 unfortunate side effects. whenever i re-create grid instances and bind them to my observable collection, it freezes my entire window for 5 seconds. when my grid grows to a big size, this delay can last for 30 seconds. when i call TradeGrid.ScrollIntoView(TradeGrid.Items(TradeGrid.Items.Count - 1)) to scroll to the bottom, it jumps to bottom and than back to the top. is there another way to achieve smooth scrolling perhaps?

  • rspec & rails 3 cannot find model object

    - by Ceilingfish
    I'm trying to put some specs around a new rails 3 project I am working on, and my first test doesn't seem to be able to find a model. I've installed rspec from the command line using: sudo gem install rspec --pre and then I put the following in my Gemfile gem "rspec-rails", ">= 2.0.0.beta.1" But when I run my test I get ./spec/models/world_spec.rb:1: uninitialized constant World (NameError) rake aborted!

    - by Eran
    Hey, I'm using web refernce call in new working thread in my application as follow: Thread callRunner = new Thread(delegate() { _mediator.IncomingCallDetails(phoneNumber); }); callRunner.Start() ; the _mediator calls the web refernce and replay to the caller in event as follow: void IncomingCallComplited(IncomingCallEventArg args) { Caller = args.Caller; Lodgers = args.Lodgers; PreviousMissions = args.PreviousMissions; } Caller ,Lodgers and PreviousMissions are properties of an object that bind to GUI element,as for now the binding works fine and i can see the values from the web refernce in screen my question is should I use Dispatcher in the event or in any other phase ? and if I do can someone please explain why?

  • WPF - Translate a point relative to MainWindow to it's coordinates relative to a child control

    - by James Cadd
    Is it possible to translate a point relative to MainWindow to be relative to one of its child controls? For example, say a control's upper left corner was located at 500, 500 relative to MainWindow what code would convert that number to (0, 0)? I'd like the solution to be agnostic of the layout mechanism (i.e. not require me to parent the control in a Canvas and use the Top and Bottom methods).

  • WPF Dockable Windows Like iGoogle

    - by Anon
    I'm looking for a dockable windows/panel control in the style of iGoogle. All of the ones I have found so far all have a fixed length on the height of your window/panel but I want to be able to have windows of varying length like iGoogle. The best I have found so far has been a control libarary called BlackLight which does not have the feature explained above.

    Is there a way to use a collection of PathGeometry like these: Path 1 F1 M 170.255,178.837L 170.255,221.158C 170.255,228.917 164.174,230.777 156.745,225.286L 136.003,209.973C 128.572,204.488 128.572,195.512 136.003,190.023L 156.745,174.706C 164.174,169.217 170.255,171.079 170.255,178.837 Z Path 2 F1 M 152.29,174.464L 134.314,187.734C 129.978,190.937 127.589,195.29 127.589,199.994C 127.589,204.7 129.978,209.057 134.314,212.26L 152.29,225.531C 150.333,229.378 145.412,229.52 139.678,225.286L 118.935,209.973C 111.506,204.489 111.506,195.512 118.935,190.022L 139.678,174.708C 145.412,170.475 150.333,170.617 152.29,174.464 Z and use them to make a custom button in the same way you can make a circular button shown in this example? http://www.wpftutorial.net/Templates.html The example involves overriding the control template and it seems a lot of work if I want to have many custom-shaped buttons. And what if I want to load the geometry points from the resource?

  • WPF TypeConverter ConvertTo not firing

    - by JFoulkes
    Hi, I have a dependency property in a class which I need to be converted to a string. I have added the TypeConverty attribute on the property. The type I am converting is the .net Style class. [TypeConverter(typeof(BulletStyleTypeConverter))] public Style BulletStyle { get { return (Style)GetValue(BulletStyleProperty); } set { this.SetValue(BulletStyleProperty, value); } } When I put the string "Rectangle" in for BulletStyle in xaml it hits the ConvertFrom method in my converter. However, when I use XamlWriter.Save() to serialise this, the property does not appear as an attribute in the string which is produced. I have implemented ConvertTo and put a breakpoint on, which is never hit. I have implemented CanConvertTo and put a breakpoint on, which IS hit and returns true. So i'm stumped as to why ConvertTo never fires.

  • WPF - Setting usercontrol width using triggers and mouseenter event

    - by BigBadJock
    I have a wrap panel full of usercontrols. When I hover the mouse over a usercontrol I want it to expand to show more details. Some stripped down sample code: <UserControl x:Class="WPFTestBed.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <UserControl.Resources> </UserControl.Resources> <UserControl.Triggers> <EventTrigger RoutedEvent="Mouse.MouseEnter"> <EventTrigger.Actions> <Setter TargetName="WPFTestBed.UserControl1" Property="Control.Width" Value="200"/> </EventTrigger.Actions> </EventTrigger> </UserControl.Triggers> <Grid Height="95" Width="123"> <Button Height="23" HorizontalAlignment="Left" Margin="17,30,0,0" Name="button1" VerticalAlignment="Top" Width="75">Button</Button> </Grid> </UserControl> I would appreciate it if someone could point out where I'm going wrong, and set me down the correct path. Ideally, I want the usercontrol to delay for x seconds when there is a mouseover, before expanding and showing the extra details.

  • wpf - window to be tight round user control

    - by Andy Clarke
    Hi, I've got a user control that I'm loading into a Window dynamically - I wanted to set the Window so that it didn't have a size and then I thought the window to resize accordingly depending on the UserControl. However it dosn't - can anyone assist please? I've made a very basic example - I've cut out the dynamic bits and just put a UserControl in a Window. What do I need to do to get the window to be tight around the UserControl? Thanks, Andy <UserControl x:Class="WpfApplication1.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300" Background="LightBlue"> <Grid> </Grid> </UserControl> <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:WpfApplication1="clr-namespace:WpfApplication1" Title="Window1" > <Grid> <WpfApplication1:UserControl1> </WpfApplication1:UserControl1> </Grid> </Window>

  • Create a grid in WPF as Template programmatically

    - by wickie79
    I want to create a basic user control with a style programmatically. In this style i want to add a Grid (no problem), but i dont can add column definitions to this grid. My example code is ControlTemplate templ = new ControlTemplate(); FrameworkElementFactory mainPanel = new FrameworkElementFactory(typeof(DockPanel)); mainPanel.SetValue(DockPanel.LastChildFillProperty, true); FrameworkElementFactory headerPanel = new FrameworkElementFactory(typeof(StackPanel)); headerPanel.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal); headerPanel.SetValue(DockPanel.DockProperty, Dock.Top); mainPanel.AppendChild(headerPanel); FrameworkElementFactory headerImg = new FrameworkElementFactory(typeof(Image)); headerImg.SetValue(Image.MarginProperty, new Thickness(5)); headerImg.SetValue(Image.HeightProperty, 32d); headerImg.SetBinding(Image.SourceProperty, new Binding("ElementImage") { RelativeSource = new RelativeSource(RelativeSourceMode.TemplatedParent) }); headerPanel.AppendChild(headerImg); FrameworkElementFactory headerTitle = new FrameworkElementFactory(typeof(TextBlock)); headerTitle.SetValue(TextBlock.FontSizeProperty, 16d); headerTitle.SetValue(TextBlock.VerticalAlignmentProperty, VerticalAlignment.Center); headerTitle.SetBinding(TextBlock.TextProperty, new Binding("Title") { RelativeSource = new RelativeSource(RelativeSourceMode.TemplatedParent) }); headerPanel.AppendChild(headerTitle); FrameworkElementFactory mainGrid = new FrameworkElementFactory(typeof(Grid)); FrameworkElementFactory c1 = new FrameworkElementFactory(typeof(ColumnDefinition)); c1.SetValue(ColumnDefinition.WidthProperty, new GridLength(1, GridUnitType.Star)); FrameworkElementFactory c2 = new FrameworkElementFactory(typeof(ColumnDefinition)); c2.SetValue(ColumnDefinition.WidthProperty, new GridLength(1, GridUnitType.Auto)); FrameworkElementFactory c3 = new FrameworkElementFactory(typeof(ColumnDefinition)); c3.SetValue(ColumnDefinition.WidthProperty, new GridLength(3, GridUnitType.Star)); FrameworkElementFactory colDefinitions = new FrameworkElementFactory(typeof(ColumnDefinitionCollection)); colDefinitions.AppendChild(c1); colDefinitions.AppendChild(c2); colDefinitions.AppendChild(c3); mainGrid.AppendChild(colDefinitions); mainPanel.AppendChild(mainGrid); FrameworkElementFactory content = new FrameworkElementFactory(typeof(ContentPresenter)); content.SetBinding(ContentPresenter.ContentProperty, new Binding() { RelativeSource = new RelativeSource(RelativeSourceMode.TemplatedParent), Path = new PropertyPath("Content") }); mainGrid.AppendChild(content); templ.VisualTree = mainPanel; Style mainStyle = new Style(); mainStyle.Setters.Add(new Setter(UserControl.TemplateProperty, templ)); this.Style = mainStyle; But the creation of FrameworkElementFactory with type ColumnDefinitionCollection will throw an exception "'ColumnDefinitionCollection' type must derive from FrameworkElement, FrameworkContentElement, or Visual3D." Who can help me?
