[Solved] Binding Event to MVVM with EventArgs

[John]

I'm trying to bind EditEnding to my ViewModel with a RadDataForm

I get a null object to my command method. I need to have access to the EditAction property of the EditEndedEventArgs but I'm getting nada. 

Here's my ViewModel info:

public ReservePartViewModel()
{
    EditEndingCommand = new Telerik.Windows.Controls.DelegateCommand(OnEditEnding);
}

public ICommand EditEndingCommand { get; set; }

private void OnEditEnding(object obj)
{
    if (obj is EditEndedEventArgs)
    {
        var args = obj as EditEndingEventArgs;
        //do stuff here?
    }
}

 

Here's my View info:

<telerik:RadDataForm CurrentItem="{Binding}" AutoEdit="True" CommandButtonsVisibility="Commit,Cancel">
    <telerik:EventToCommandBehavior.EventBindings>
        <telerik:EventBinding Command="{Binding EditEndingCommand}" EventName="EditEnding" />
    </telerik:EventToCommandBehavior.EventBindings>
</telerik:RadDataForm>

Found the answer on Stack Overflow

Needed this PassEventArgsToCommand="True":

<telerik:RadDataForm CurrentItem="{Binding}" AutoEdit="True" CommandButtonsVisibility="Commit,Cancel">
    <telerik:EventToCommandBehavior.EventBindings>
        <telerik:EventBinding Command="{Binding EditEndingCommand}" EventName="EditEnding" PassEventArgsToCommand="True" />
    </telerik:EventToCommandBehavior.EventBindings>
</telerik:RadDataForm>

Does anyone know which version this PassEventArgsToCommand was introduced ??  We are forced to stay on version 2013 and we don't seem to have this option available to us in XAML ?

 

Cheers

Hi John,

The PassEventArgsToCommand property was introduced in the Q1 version of 2014 of Telerik UI for WPF.

Hello John,

The PassEventArgsToCommand property was actually introduced with the Q3 2013 SP1. I apologize for misleading you on that.
