Trigger for ComboBox in Silverlight
- by Budda
Is there any possibility to display selected item of the ComboBox (after popup closing) in a way that is different from its displaying in DropDown List (There are players number and name in the dropdown list, but after list closing I want to see only its number).
How can I change a background for the player with some Flag?
As far as I know, all of that can be done with triggers, but are they supported in Silverlight 4, VS2010, Silverlight Toolkit 4? In my case the following code
<ComboBox ItemsSource="{Binding PlayersAll}"
SelectedItem="{Binding Path=SelectedPlayer, Mode=TwoWay}"
>
<ComboBox.ItemTemplate>
<DataTemplate>
<ToolkitControls:WrapPanel Orientation="Horizontal">
<TextBlock Text="{Binding TeamNumber}"/>
<TextBlock Text=" - "/>
<TextBlock Text="{Binding ShortName}"/>
</ToolkitControls:WrapPanel>
<DataTemplate.Triggers>
<Trigger Property="HasError" Value="True">
<Setter Property="Background" TargetName="FlagSet" Value="Red"/>
</Trigger>
</DataTemplate.Triggers>
</DataTemplate>
</ComboBox.ItemTemplate>
</ComboBox>
gives an error:
The property 'Triggers' does not exist on the type 'DataTemplate' in the XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'
what is wrong here? Here are my namespaces:
