Prevent double-click from double firing a command

Question

Given that you have a control that fires a command:

Is there a way to prevent the command from being fired

Answer 1

A simple and elegant solution is to create a Behavior disabling reaction on second click in double-click scenario. That's pretty easy to use:

Behavior (more about behaviors - https://www.jayway.com/2013/03/20/behaviors-in-wpf-introduction/)

using System.Windows.Controls;
using System.Windows.Input;
using System.Windows.Interactivity;

public class DisableDoubleClickBehavior : Behavior
{
    protected override void OnAttached()
    {
        base.OnAttached();
        AssociatedObject.PreviewMouseDoubleClick += AssociatedObjectOnPreviewMouseDoubleClick;
    }

    private void AssociatedObjectOnPreviewMouseDoubleClick(object sender, MouseButtonEventArgs mouseButtonEventArgs)
    {
        mouseButtonEventArgs.Handled = true;
    }

    protected override void OnDetaching()
    {
        AssociatedObject.PreviewMouseDoubleClick -= AssociatedObjectOnPreviewMouseDoubleClick;
        base.OnDetaching();
    }
}
