Question

I need to open up a menu and since WP7 is not designed to perform such actions, I am taking help of Toolkit. Following is the sample code:

<Border BorderThickness="3" Padding="6">
     <toolkit:ContextMenuService.ContextMenu>
         <toolkit:ContextMenu>
             <toolkit:MenuItem Header="item1" Click="Item1_Click" />
             <toolkit:MenuItem Header="item2" Click="Item2_Click" />
             <toolkit:MenuItem Header="item3" Click="Item3_Click" />
         </toolkit:ContextMenu>
     </toolkit:ContextMenuService.ContextMenu>
     <TextBlock Text="Tap" />
</Border>

Now this works fine as long as user does a press and hold action. But I can’t ask the user for such action. I need to display the menu on a single click/tap/touch/gesture (watever you want to call it). Can someone please suggest? If you think toolkit is not the best way, then please suggest alternatives with sample code. I tried popup but that did more bad than good to my applicaiton

You could add GestureListener to the Border and subscribe to the Tap event. In the event handler, you get the ContextMenu for the Border and set IsOpen to true if it doesn’t have a logical parent.

<Border BorderThickness="3" Padding="6">
    <toolkit:GestureService.GestureListener>
        <toolkit:GestureListener Tap="GestureListener_Tap" />
    </toolkit:GestureService.GestureListener>
    <toolkit:ContextMenuService.ContextMenu>
        <toolkit:ContextMenu>
            <toolkit:MenuItem Header="item1" Click="Item1_Click" />
            <toolkit:MenuItem Header="item2" Click="Item2_Click" />
            <toolkit:MenuItem Header="item3" Click="Item3_Click" />
        </toolkit:ContextMenu>
    </toolkit:ContextMenuService.ContextMenu>
    <TextBlock Text="Tap" />
</Border>

private void GestureListener_Tap(object sender, GestureEventArgs e)
{
    Border border = sender as Border;
    ContextMenu contextMenu = ContextMenuService.GetContextMenu(border);
    if (contextMenu.Parent == null)
    {
        contextMenu.IsOpen = true;
    }
}
