Display RadContextMenu only at specific column

[John]

Hi,

I have a context menu in RadGridView:

                    <telerik:RadContextMenu.ContextMenu>
                        <telerik:RadContextMenu x:Name="radContextMenu"
                                         Opened="RadContextMenu_Opened">
                            <telerik:RadMenuItem Header="{Binding MoveUpCommand.Text}"
                                          Command="{Binding MoveUpCommand}" />
                            <telerik:RadMenuItem Header="{Binding MoveDownCommand.Text}"
                                          Command="{Binding MoveDownCommand}" />
                            <telerik:RadMenuItem Header="{Binding StartNextAction.Text}"
                                                 Command="{Binding StartNextActionCommand}">
                                <nav:RadMenuItem.Icon>
                                    <Image Source="/MyApp;component/Images/Buttons/gear_shifbutton.png" Width="16" Height="16" />
                                </nav:RadMenuItem.Icon>
                            </telerik:RadMenuItem>
                        </telerik:RadContextMenu>
                    </telerik:RadContextMenu.ContextMenu>

and I want display it only at specific datacolumn. Is it possible? I haven't found any example related to this problem.

I'm using I'm using 2010.1.603.1040

Hi John,

You may try to handle the Opening event of the context menu and cancel it if it is not above the column you want. For example:

private void RadContextMenu_Opening(object sender, Telerik.Windows.RadRoutedEventArgs e)
        {
            RadContextMenu contextMenu = sender as RadContextMenu;
            GridViewCell clickedCell = contextMenu.GetClickedElement<GridViewCell>();
            if (clickedCell.Column.UniqueName != "Name")
            {
                e.Handled = true;
            }
        }

Thanks Maja for you reply,

I haven't "Opening" event in my version of contextmenu and I can't upgrade it to new.

Is there any other way to struggle with it?

Hello John,

May you clarify which version of RadControls are you working with ? Why is it not possible for you to upgrade ?
Generally, our recommendation is always to work with the most recent version since you can benefit from all the features we introduce as well as from the bug fixes added.

I'm using I'm using 2010.1.603.1040

Now I can't upgrade because of some dependencies in other controls to your older version.
I'm new in this company, and now I got order, that for next months I must work with those older controls.

Hello John,

You may try to define a ContextMenu similar to this example. In your case, however, you may verify whether the cell (the element returned by GetClickedElemente<T>() method) belongs to the column you want.
