Hi All! I have a <DataTrigger> element that is checking the value of an enum for one of three states. in each state i change an image, and fire off an animation. My problem is that although the state change modifies the image, the animation only works correctly for the first time, and thereafter, only the LAST trigger makes the animation work. Ie, the storyboard faded up and then flashed the icon. however if the visibility was set at all, it only ever appeared once, so commentin out the visibility setters makes it visible, but the fading part of the anim only works the first time, and strangely for the last trigger. Any ideas? Am i misunderstanding the usage of the Entry & Exit actions? Cheers! <ControlTemplate.Triggers> <DataTrigger Binding="{Binding Path=ServerState}" Value="Idle"> <DataTrigger.Setters> <!--<Setter TargetName="theImage" Property="Visibility" Value="{x:Static Visibility.Hidden}" />--> </DataTrigger.Setters> </DataTrigger> <DataTrigger Binding="{Binding Path=ServerState}" Value="Busy"> <DataTrigger.Setters> <!--<Setter TargetName="theImage" Property="Visibility" Value="{x:Static Visibility.Visible}" />--> <Setter TargetName="theImage" Property="Source" Value="download_server.png"></Setter> </DataTrigger.Setters> <DataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource FadeUpAndFlash}" x:Name="busyAnim"/> </DataTrigger.EnterActions> <DataTrigger.ExitActions> <StopStoryboard BeginStoryboardName="busyAnim" /> </DataTrigger.ExitActions> </DataTrigger> <DataTrigger Binding="{Binding Path=ServerState}" Value="Failed"> <DataTrigger.Setters> <!--<Setter TargetName="theImage" Property="Visibility" Value="{x:Static Visibility.Visible}" />--> <Setter TargetName="theImage" Property="Source" Value="desable_server.png"></Setter> </DataTrigger.Setters> <DataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource FadeUpAndFlash}" x:Name="failAnim"/> </DataTrigger.EnterActions> <DataTrigger.ExitActions> <StopStoryboard BeginStoryboardName="failAnim" /> </DataTrigger.ExitActions> </DataTrigger> <DataTrigger Binding="{Binding Path=ServerState}" Value="Complete"> <DataTrigger.Setters> <!--<Setter TargetName="theImage" Property="Visibility" Value="{x:Static Visibility.Visible}" />--> <Setter TargetName="theImage" Property="Source" Value="enable_server.png"></Setter> </DataTrigger.Setters> <DataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource FadeUpAndFlash}" x:Name="completeAnim" /> </DataTrigger.EnterActions> <DataTrigger.ExitActions> <StopStoryboard BeginStoryboardName="completeAnim" /> </DataTrigger.ExitActions> </DataTrigger> </ControlTemplate.Triggers> |
