Radgridview contextmenu not working in the latest version

[Gita]

Hello Team,
We are upgrading the telerik controls to q2 2011 version. In the previous version the Radgridview right click contextmenu was working fine, but not now. What do I have to change in the below code to get the popup menu when I right click the selected row?
Let me know.

Thanks

<telerik:RadGridView.ContextMenu>
    <ContextMenu IsVisibleChanged="ContextMenu_IsVisibleChanged">
        <MenuItem Header="Export To Excel" Command="Commands:GlobalCommands.ExportGridToExcel"
                  CommandParameter="{Binding Path=PlacementTarget, RelativeSource={RelativeSource AncestorType={x:Type ContextMenu}}}"/>
        <MenuItem Header="Export To Word" Command="Commands:GlobalCommands.ExportGridToWord"
                  CommandParameter="{Binding Path=PlacementTarget, RelativeSource={RelativeSource AncestorType={x:Type ContextMenu}}}"/>
    </ContextMenu>
</telerik:RadGridView.ContextMenu>

Hello Gita,

I have tested the case and everything works as expected on my side. Would you take a look at the sample attach to verify whether you can reproduce the behavior on it ?
 

All the best,

Hello Team,
I checked out your sample project and it is working fine. Same code only I am having it in my screen.
It is basically coming up with default popup menu (contains Floating,Dockable,Tabbed document,Auto hide, hide)

This standard popup menu is overriding my popup menu(Export to Excel...). I am getting this popup menu not only in the gridview,
in the whole screen. Anywhere it  is coming when I right click.

I tried to attache the image/screenshot for you, but didn't know how to attach the image in the forum.

Please let me know the solution for this.

Thanks

Hello Team,

Throught out all the screens everywhere I am getting this default right click popup menu. It contains Floating,Dockable,Tabbed Document, Auto Hide,Hide.

This is overiding my Radigridview popup menu. I didn't have any problem in the older version. Which control has the default right click pop up option? 

Any help?

Thanks
