datatrigger

I have a TextBox control defined in XAML and I want to apply different background colors to the TextBox based on its IsReadOnly or IsEnabled properties. I used dataTriggers to actually switch between the colors as shown below: <Style x:Key="TextBoxStyle" TargetType="TextBox"> <Style.Triggers> <DataTrigger Binding="{Binding IsEnabled}" Value="True"> <Setter Property="TextBox.Background" Value="Yellow"/> </DataTrigger> <DataTrigger Binding="{Binding IsReadOnly}" Value="True"> <Setter Property="TextBox.Background" Value="Red"/> </DataTrigger> <MultiDataTrigger> <MultiDataTrigger.Conditions>

I have a rectangle which I am animating the backround colour of. It should change to green each time a particular number goes up. And red when it goes dowm. If the number doesn't change for a while it slowly fades back to its default colour So the animation changes th background from grey to red very quickly and then takes several seconds to fade back to grey. I have added as DataTrigger which is bound to 1 or -1 depending on how the number has changed The problem is that if the number keeps going up the animation does not get restarted. e.g. if the sequence of numbers went 1, 2, 3, 4, 5. Then

The goal here would be to check all grid checkboxes if the header checkbox changes: <Window.Resources> <Style TargetType="CheckBox" x:Key="InnerBox"> <Setter Property="HorizontalAlignment" Value="Center" /> <Style.Triggers> <DataTrigger Value="True" Binding="{Binding IsChecked, ElementName=HeaderCheckbox}"> <Setter Property="IsChecked" Value="True" /> </DataTrigger> <DataTrigger Value="False" Binding="{Binding IsChecked, ElementName=HeaderCheckbox}"> <Setter Property="IsChecked" Value="False" /> </DataTrigger> </Style.Triggers> </Style> </Window.Resources> <DataGrid> <DataGrid.Columns> <!--
