Tag: MouseDoubleClick

I want to implement a PopUpWindowAction and InteractionRequestTrigger via the Micrsoft PRISM Libray:
But it starts with basic problems:
I’m not able to create a correct invokeCommandAction, the RaisItemSelection method gets never executed?

Xaml:

<s:SciChartSurface>
  <i:Interaction.Triggers>
                <i:EventTrigger EventName="MouseDoubleClick">
                    <i:InvokeCommandAction Command="{Binding MouseDoubleClickCommand}" CommandParameter="{}" />
                </i:EventTrigger>
    </i:Interaction.Triggers>
</<s:SciChartSurface>

xaml.cs:

MouseDoubleClickCommand = new DelegateCommand<object>(RaiseItemSelection);
 private void RaiseItemSelection(object obj)
        {
        }
