Why doesn't WPF border control have a mousedoubleclick event?

Question

Why doesn't WPF border control have a mousedoubleclick event? I have a ItemsControl with some layout stuff in it for a DataTemplate. I want to handle the double click event to pop up a details dialog, but the border, my layout container, doesn't appear to expose the event.

Any suggestions on how to either get at the double click event, or rework the xaml to make it possible?

Answer 1

Just use InputBindings.

<Border>     <Border.InputBindings>         <MouseBinding MouseAction="LeftDoubleClick" Command="..."/>     </Border.InputBindings> </Border> 

In general; avoid using events if not developing controls in WPF. Usually the usage of code behind based events is a strong indication for a MVVM Pattern break.

MouseDoubleClick is declared on Control so you just need an instance of some Control in your ItemTemplate. The simplest thing to do is use the base Control class which doesn't have any other behavior and just give it a customized template with what's in your ItemTemplate now.

<ItemsControl>     <ItemsControl.ItemTemplate>         <DataTemplate>             <Control MouseDoubleClick="Control_MouseDoubleClick">                 <Control.Template>                     <ControlTemplate>                         <Border>                             <!--Other ItemTemplate stuff-->                         </Border>                     </ControlTemplate>                 </Control.Template>             </Control>         </DataTemplate>     </ItemsControl.ItemTemplate> </ItemsControl>
