Question

I am using style to define the template of a predefined control. The control is part of a Framework which I cannot modify. This control has a DataGrid and for that I want to add a MouseDoubleClick event. The event handler (HandleGridDoubleClick) is already specified in the framework.

Is there a way to bind to this method ? I understand it would have been easy if the Framework provided a Command for that.

<Style
    TargetType="xyz:FileMessageControl">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate
                TargetType="xyz:FileMessageControl">
                   <Grid>
                    .....
                       <DataGrid MouseDoubleClick = HandleGridDoubleClick>
                        .....
                       </DataGrid>
                   </Grid>
           </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Try something like this (you need to use Interaction dll)

<i:Interaction.Triggers>                            
    <i:EventTrigger EventName="MouseDoubleClick">
        <action:ExecuteCommandAction Command="{Binding DataContext.HandleGridDoubleClick}" />
     </i:EventTrigger>
</i:Interaction.Triggers>
