Consider the following, simple code: XAML: <Grid Height="60" Name="grid"> <Grid.ColumnDefinitions> <ColumnDefinition Width="162*" /> <ColumnDefinition x:Name="coltest" Width="316*" /> <ColumnDefinition Width="239*" /> </Grid.ColumnDefinitions> </Grid> <Label MouseDoubleClick="TextBox_MouseDoubleClick" Content="{Binding ElementName=coltest, Path=ActualWidth}" Grid.Row="1"/> The MouseDoubleClick event: private void TextBox_MouseDoubleClick(object sender, MouseButtonEventArgs e) { grid.RowDefinitions.Add(new RowDefinition()); for (int i = 0; i < grid.ColumnDefinitions.Count; i++) { Random r = new

I have a 3 column grid in a window with a GridSplitter on the first column. I want to set the MaxWidth of the first column to a third of the parent Window or Page Width (or ActualWidth ) and I would prefer to do this in XAML if possible. This is some sample XAML to play with in XamlPad (or similar) which shows what I'm doing. <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" > <Grid> <Grid.ColumnDefinitions> <ColumnDefinition x:Name="Column1" Width="200"/>

I tried to solve my previous question with manually binding the Width property of the DataGridTextColumn here is the first Version of my XAML Code. <DataGrid AutoGenerateColumns="False" Background="White" ItemsSource="{Binding Items, Mode=OneWay}" HorizontalGridLinesBrush="Silver" VerticalGridLinesBrush="Silver" Margin="332,10,10,10" CanUserAddRows="False" CanUserDeleteRows="False" x:Name="myDataGrid" ColumnWidth="*"> <DataGrid.Columns> <DataGridTextColumn Width="{Binding Path=ActualWidth, Converter={StaticResource ResourceKey=WidthValueConverter}, RelativeSource={RelativeSource AncestorType

I need a Viewport3D for the sole purpose of doing geometric calculations using Petzold.Media3D.ViewportInfo . I would prefer not to have to place it in a Window or otherwise render it. I'm attempting to accomplish this by instantiating a Viewport3D and setting a few properties using the following C# method: private Viewport3D CreateViewport(MainSettings settings) { var cameraPosition = new Point3D(0, 0, settings.CameraHeight); var cameraLookDirection = new Vector3D(0, 0, -1); var cameraUpDirection = new Vector3D(0, 1, 0); var camera = new PerspectiveCamera { Position = cameraPosition,

Consider the following: Let's say the Window is 1024x768 and the ViewBox fills the entire window, this means the TextBox is really large on the screen. I want to get the size of the TextBox as it is currently on the screen. If I get DesiredSize or ActualSize or even RenderedSize I always get 100. Any suggestions? Update: I could probably get the ActualWidth of the ViewBox and divide it by the ActualWidth of it's child which would give me the current scale factor and expose that as a property somehow but I'm not sure that's the best way to do it.
