Disable Double Click In WPF Application

Many times, we want to disable the double click of a button in an application. This may be to avoid opening the same popup twice or to avoid saving a new record 2 times.

Whatever the reason, you may need to disable a specific button or, in my case, you may want to do this across the application by default.

 

To do it across the application in a clean way, include the following class in your project.

public static class ControlHelper
{
        /// <summary>
        /// The disable double click property
        /// </summary>
        public static readonly DependencyProperty DisableDoubleClickProperty =
            DependencyProperty.RegisterAttached("DisableDoubleClick", typeof(bool), typeof(ControlHelper), new FrameworkPropertyMetadata(false, OnDisableDoubleClickChanged));

        /// <summary>
        /// Sets the disable double click.
        /// </summary>
        /// <param name="element">The element.</param>
        /// <param name="value">if set to <c>true</c> [value].</param>
        public static void SetDisableDoubleClick(UIElement element, bool value)
        {
            element.SetValue(DisableDoubleClickProperty, value);
        }

        /// <summary>
        /// Gets the disable double click.
        /// </summary>
        /// <param name="element">The element.</param>
        /// <returns></returns>
        public static bool GetDisableDoubleClick(UIElement element)
        {
            return (bool)element.GetValue(DisableDoubleClickProperty);
        }

        /// <summary>
        /// Called when [disable double click changed].
        /// </summary>
        /// <param name="d">The d.</param>
        /// <param name="e">The <see cref="DependencyPropertyChangedEventArgs"/> instance containing the event data.</param>
        private static void OnDisableDoubleClickChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
        {
            var control = (Control)d;
            if ((bool)e.NewValue)
            {
                control.PreviewMouseDown += (sender, args) =>
                {
                    if (args.ClickCount > 1)
                    {
                        args.Handled = true;
                    }
                };
            }
        }
}

Assuming, you have a common style defined for buttons in your application to maintain the same look and feel, 

add the following line to the style applied to your buttons in the entire application.

<Setter Property="helpers:ControlHelper.DisableDoubleClick" Value="true"/>

This should disable the double click of a button by default on all the buttons using that particular style.

 

To apply the same to a specific button, first add a namespace in which the ControlHelper class resides in the XAML page, using the following syntax.

1. <Window xmlns:helpers="clr-namespace:MentionFulNameSpaceHere">

Then, use the following syntax to declare the button.

1. <Button helpers:ControlHelper.DisableDoubleClick="true"/>

This should disable double click of a specifc button.
