问题 I was wondering if I can have 2 controls in a horizontal-oriented StackPanel so that the right item should be docked to the right side of the StackPanel. I tried the following but it didn't work: <StackPanel Orientation="Horizontal"> <TextBlock>Left</TextBlock> <Button Width="30" HorizontalAlignment="Right">Right<Button> </StackPanel> In the snippet above I want the Button to be docked to the right side of the StackPanel. Note: I need it to be done with StackPanel, not Grid etc. 回答1: You can

问题 Given a StackPanel: <StackPanel> <TextBox Height="30">Apple</TextBox> <TextBox Height="80">Banana</TextBox> <TextBox Height="120">Cherry</TextBox> </StackPanel> What's the best way to space out the child elements so that there are equally-sized gaps between them, even though the child elements themselves are of different sizes? Can it be done without setting properties on each of the individual children? 回答1: Use Margin or Padding, applied to the scope within the container: <StackPanel>

VirtualizingStackPanel + MVVM + multiple selection

问题 I have implemented a selection pattern similar to the one described in this post using a ViewModel to store the IsSelected value, and by binding the ListViewItem.IsSelected to the ViewModel IsSelected: <ListView.ItemContainerStyle> <Style TargetType="{x:Type ListViewItem}"> <Setter Property="IsSelected" Value="{Binding Mode=TwoWay, Path=IsSelected}"/> </Style> </ListView.ItemContainerStyle> It works in general, but I encounter a severe problem. By using the a VirtualizingStackPanel as the

In the following WPF XAML the ScrollViewer does not work (it displays a scroll bar but you cannot scroll and the contents go off the window to the bottom). I can change the outer StackPanel to a Grid and it will work. However, in my application from which I reproduced the following code, I need to have an outer StackPanel. What do I have to do to the StackPanel to make the ScrollViewer show a usable scrollbar? e.g. VerticalAlignment="Stretch" Height="Auto" don't work. <StackPanel> <ScrollViewer> <StackPanel> <TextBlock Text="This is a test"/> <TextBlock Text="This is a test"/> <TextBlock Text=

WPF VirtualizingStackPanel for increased performance

问题 I would like a simple description of how to implement a virtualizingstackpanel for an ItemsControl that is databound to an ObservableCollection in my MVVM. I have an ItemsControl instance for each tab in a tab control, and switching tabs becomes VERY slow when the ItemsControl grows larger. What can I do to speed up the app? I opened up a WPF profiler and saw that each element (which is a custom user control) displayed in my ItemsControl of each tab had its own ContentPresenter . So I

Hide TabControl buttons to manage stacked Panel controls

I need to handle multiple panels, containing variuous data masks. Each panel shall be visible using a TreeView control. At this time, I handle the panels visibility manually, by making the selected one visible and bring it on top. Actually this is not much confortable, especially in the UI designer, since when I add a brand new panel I have to resize every panel and then design it... A good solution would be using a TabControl, and each panel is contained in a TabPage. But I cannot find any way to hide the TabControl buttons, since I already have a TreeView for selecting items. Another
