Command binding when dialog is closed

[jeljeljel]

How can an application be notified when a dialog is closed?  Is there something built into the dialog API that will notify when it's closing?

Hi John,

You could use the Popup IsOpen property to get notified when the control is closed. You could either bind it to a boolean property in the ViewModel or use PropertyChanged event of the Popup and track when IsOpen is updated, here is a quick snippet on this:

this.popup.PropertyChanged += Popup_PropertyChanged;

private void Popup_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
{
    if(e.PropertyName == "IsOpen")
    {

    }
}

I hope this would be of help.
