Interaction.Trigger with UserControl

Question

Hi everyone,
I've finished creating an UserControl called CustomMessageBox which contains a TextBox and 2 buttons : OK | Cancel . I want to apply my control to MVVM model, but , when I use interaction.trigger to interact with the Confirm and Cancel event (Confirm and
Cancel are my 2 custom events) , like this :
<i:Interaction.Triggers>
<i:EventTrigger EventName="Confirm">
<command:EventToCommand Command ="{Binding CloseTheWindow}"/>
</i:EventTrigger>
</i:Interaction.Triggers>
But nothing happens . My window still opens 
Can anyone help me please ?

How do you implement and raise the Confirm event then? And why? You might as well invoke the command directly in the click event handler of the Button:
private void Confirm_Click(object sender, RoutedEventArgs e) {
dynamic viewModel = this.DataContext;
//invoke the command directly here:
viewModel.CloseTheWindow.Invoke(null);
...or you could just bind the "CloseTheWindow" command to the confirm button directly:
<Button Content="Confirm" Command="{Binding CloseTheWindow}" />
Of course this still assumes that the DataContext of your CustomMessageBox UserControl has been set to an instance of a view model class that contains a "CloseTheWindow" command property.
