问题 I would like to combine the DisplayNames from two different ViewModels, but only IF the first is not equal to a NullObject.

问题 I'm try to set the Foreground colour on a Hyperlink using a Style object in an ancestor's Resources , but it's not having any effect. I even used the BasedOn tip from Changing Hyperlink foreground without losing hover color, but it's not made any difference - I still get a blue hyperlink that is red on hover.

问题 So I am trying to have a message displayed when the input is invalid, suppose I want something other than a ToolTip , something that stays until the error is corrected. I tried having an ErrorTemplate <Style TargetType="{x:Type TextBox}"> <Setter Property="Validation.ErrorTemplate"> <Setter.Value> <ControlTemplate> <StackPanel> <Border BorderBrush="Red" BorderThickness="1"> <AdornedElementPlaceholder x:Name="adornedErrorElement" /> </Border> <Label Background="Red" Foreground="White" FontSize

问题 I'm binding TreeView. My reason is treeview level 0 is unselectable.
