Hi,

I need separate context menu for the grid rows and the grid headers.

I defined the rows context menu in the xaml like this:

<telerikGrid:RadGridView x:Name="ordersGrid" AutoGenerateColumns="False" DataLoadMode="Synchronous" >
            <Navigation:RadContextMenu.ContextMenu>
                <Navigation:RadContextMenu Opened="RadContextMenu_Opened" ItemClick="RadContextMenu_ItemClick">
                    <Navigation:RadContextMenu.Items>
                        <Navigation:RadMenuItem Header="Update Order" />
                        <Navigation:RadMenuItem Header="Cancel Order" />
                        <Navigation:RadMenuItem Header="View Details" />
                    </Navigation:RadContextMenu.Items>
                </Navigation:RadContextMenu>
            </Navigation:RadContextMenu.ContextMenu>

and i defined in the code the context menu for the headers.

The problem is that the main context menu overrides the header context menu. I even try to remove it in the loaded event but it didn't help:


        void ordersGrid_Loaded(object sender, RoutedEventArgs e)
        {
            GridViewHeaderRow headerRow = ordersGrid.ChildrenOfType<GridViewHeaderRow>().FirstOrDefault();
            IEnumerable<GridViewHeaderCell> cells = headerRow.Cells.OfType<GridViewHeaderCell>();

            /**remove the default menu from the header in order to ser a separate menu for header**/
            foreach (GridViewHeaderCell cell in cells)
            {
                var x = cell.ContextMenu;
                RadContextMenu.SetContextMenu(cell, null);
            }
            GridViewHeaderMenu gvhm = new GridViewHeaderMenu(ordersGrid);
            gvhm.InitializeMenus();
        }

How can i achieve it?

Thanks,

Ofer

Hi ofer alper,

Instead of setting  context menu for the entire RadGridView I would reccomend to do the following :

Using global style set the context menu to GridViewHeaderCell( as target type)   and the same way another context menu to the GridViewCell element.

Let me know if you have any troubles implementing this approach.
