There is a Silverlight UserControl
which got an MouseLeftButtonUp
event. In xaml I add two triggers for this event. In which order Silverlight xaml-parser will parse and attach those triggers and can I be sure that trigger above will invoke first?
...
<i:Interaction.Triggers>
<i:EventTrigger EventName="MouseLeftButtonUp">
<i:InvokeCommandAction Command="{StaticResource someCommand}"/>
<AttachedBehaviors:SomeBehavior Parameter="Apple"/>
</i:EventTrigger>
</i:Interaction.Triggers>
...
WPF is processing triggers in declared order.
Hope, Silverlight behave exactly that same.
Even if the order is defined I wouldn't do this. Add the order you want to the handler of the command.
void someCommand_Executed()
{
DoFirstThing();
DoSecondThing();
}
This kind of code will cause pain in the long run because the order is not easily enforced and you are creating a dependency between two methods.
