Several MultiDataTriggers works only for the last one

c#, multidatatrigger, wpf, xaml

Solution

I found it out! I need to remove the previous storyboard at the exit-action like below. Now it works :)

<MultiDataTrigger>
    <MultiDataTrigger.Conditions>
        <Condition Binding="{Binding Path=GroupStyle}" Value="GroupStyle1"/>
        <Condition Binding="{Binding Path=IsGrouped}" Value="False"/>
    </MultiDataTrigger.Conditions>
    <MultiDataTrigger.EnterActions>
        <BeginStoryboard x:Name="BeginStoryboard_TurnToUnselectedStyle1" Storyboard="{StaticResource Storyboard_TurnToUnselectedStyle1}"/>
    </MultiDataTrigger.EnterActions>
    <MultiDataTrigger.ExitActions>
        <RemoveStoryboard BeginStoryboardName="BeginStoryboard_TurnToUnselectedStyle1"/>
    </MultiDataTrigger.ExitActions>
</MultiDataTrigger>

Problem

In a `UserControl` I have a DP of type `enum` (`GroupStyle` of type `eGroupStyle`) and a DP of type `bool` (`IsGrouped`). I need to begin some storyboard in all possible conditions. But the last `MultiDataTrigger` works only. Where did I wrong? Also I'd like to know whether a simpler way exists to factor these conditions. (checking `IsGrouped` once.) C#: ``` enum eGroupStyle { GroupStyle1, GroupStyle2, ∙∙∙, GroupStyleN, } ``` XAML: ``` <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding GroupStyle}" Value="GroupStyle1"/> <Condition Binding="{Binding IsGrouped}" Value="False"/> </MultiDataTrigger.Conditions> <MultiDataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource Storyboard_TurnToUnselectedStyle1}"/> </MultiDataTrigger.EnterActions> </MultiDataTrigger> <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding GroupStyle}" Value="GroupStyle1"/> <Condition Binding="{Binding IsGrouped}" Value="True"/> </MultiDataTrigger.Conditions> <MultiDataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource Storyboard_TurnToSelectedStyle1}"/> </MultiDataTrigger.EnterActions> </MultiDataTrigger> <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding GroupStyle}" Value="GroupStyle2"/> <Condition Binding="{Binding IsGrouped}" Value="False"/> </MultiDataTrigger.Conditions> <MultiDataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource Storyboard_TurnToUnselectedStyle2}"/> </MultiDataTrigger.EnterActions> </MultiDataTrigger> <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding GroupStyle}" Value="GroupStyle2"/> <Condition Binding="{Binding IsGrouped}" Value="True"/> </MultiDataTrigger.Conditions> <MultiDataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource Storyboard_TurnToSelectedStyle2}"/> </MultiDataTrigger.EnterActions> </MultiDataTrigger> ∙∙∙ <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding GroupStyle}" Value="GroupStyleN"/> <Condition Binding="{Binding IsGrouped}" Value="False"/> </MultiDataTrigger.Conditions> <MultiDataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource Storyboard_TurnToUnselectedStyleN}"/> </MultiDataTrigger.EnterActions> </MultiDataTrigger> <MultiDataTrigger> <MultiDataTrigger.Conditions> <Condition Binding="{Binding GroupStyle}" Value="GroupStyleN"/> <Condition Binding="{Binding IsGrouped}" Value="True"/> </MultiDataTrigger.Conditions> <MultiDataTrigger.EnterActions> <BeginStoryboard Storyboard="{StaticResource Storyboard_TurnToSelectedStyleN}"/> </MultiDataTrigger.EnterActions> </MultiDataTrigger> ```
