stackpanel

Is there an easy way to set default space between items inside StackPanel so I'll don't have to set Margin property on each item? if all the controls are the same then do as IanR suggested and implement a Style that catches that control. if it's not then you can't create a default style to a base class because it just won't work. the best way for situations like these is to use a very neat trick - attached properties (aka Behaviors in WPF4) you can create a class that has an attached property, like so: public class MarginSetter { public static Thickness GetMargin(DependencyObject obj) { return

i want to know the height of all items my StackPanel . What is the difference between: Height - Gets or sets the suggested height of the element. ActualHeight - Gets the rendered height of this element. ( readonly ) ExtentHeight - Gets a value that contains the vertical size of the extent. ( readonly ) ViewportHeight - Gets a value that contains the vertical size of the content's viewport. ( readonly ) DesiredSize - Gets the size that this element computed during the measure pass of the layout process. ( readonly ) RenderSize - Gets (or sets, but see Remarks) the final render size of this

Similar to the Stackpanel, where I can have controls such as textboxes and buttons as inner-XAML: <StackPanel> <Button Content="OK"> <Button Content="Cancel"> <Button Content="Apply"> </StackPanel> What I need is: <myControls:myOptionsList> <Button Content="OK"> <Button Content="Cancel"> <Button Content="Apply"> </myControls:myOptionsList> Assuming your UserControl has an inner Panel element where the additional elements should be placed, i.e. like this: <UserControl x:Class="YourNamespace.OptionsControl" ...> <Grid> <GroupBox Header="Options"> <StackPanel x:Name="optionsPanel"/> </GroupBox> <

This code: <StackPanel Orientation="Horizontal"> <RichTextBox /> <Button Content="Dialog" /> </StackPanel> shows the button somewhere on the left side of the StackPanel ONTO the RichTextBox, WHY? edit: Oh I just saw its a width problem. The RTB has nearly no width and the button is righthand of it. edit: seems I run into this bug: WPF RichTextBox with no width set solution does not work for me! You'd be better off using a Grid and the HorizontalAlignment (and VerticalAlignment) properties of the RTB. <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Grid.ColumnDefinitions>

I've started exploring the Data and UI virtualization features in WPF recently and stumbled upon something strange. I created a DataGrid 's with Virtualizing enabled and filled it with a list with 1,000,000 items. This works great and amazingly fast. <Grid> <DataGrid x:Name="employees" VirtualizingPanel.IsVirtualizing="True" VirtualizingPanel.IsContainerVirtualizable="True" VirtualizingPanel.VirtualizationMode="Recycling"/> </Grid> However, when I nested it under a StackPanel it loads for over a minute until I get OutOfMemoryException . I've set the same VirtualizingPanel properties on the

I need to fill empty space with last element in stackpanel (Frame): <DockPanel> <StackPanel Orientation="Vertical"> <Frame NavigationUIVisibility="Hidden" Height="100" x:Name="_menu" /> <Frame NavigationUIVisibility="Hidden" x:Name="_mainFrame" /> </StackPanel> </DockPanel> _mainFrame - fill empty space from _menu Frame to the bottom StackPanel is not the layout container for allowing elements to "fill remaining space". StackPanel has a specific purpose among other layout containers. it's to "Stack" items vertically/horizontally and works based on it's children's desired height than what's
