Introduction

Some classes like Button an MenuItem provided a property named Command which makes coding simplier, but most other classes do not provide same kind of functionality for each events.

I want to implement a Command for DoubleClick, I did tried Googled, there are some solution included using EventSetter or something like that, but it is too complicated for me, so I developed a new control just for doing that.

Background

The control is very simple...(96 lines), it is actually a DockPanel which you can used to host your control (which implement doubleclick).

Using the code

<Window x:Class="WPF_DirectoryLister_DMVVM.Window1"
        xmlns:control="clr-namespace:QuickZip.Windows.Controls"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="300" Width="600">
         
        <Grid>
        <control:TrapDoubleClick>
            <Label control:TrapDoubleClick.Command="ApplicationCommands.Help">
                DoubleClickMe
            </Label>
        </control:TrapDoubleClick>
        </Grid>
</Window>         

Points of Interest

Took me a while to figure out, if you want to override OnMouseLeftButtonDown method, you will have to set Control.AllowDrop to true.
