Context menu in GridView

[Marco]

Hi,
I want to use context menus in my grid, but I might be doing something wrong because I only get the Silverlight configuration option when I right click on the grid.

I followed the website example attaching one context menu per row, but the event "OnMenuOpen" never gets triggered

private void SamplesGrid_RowLoaded(object sender, RowLoadedEventArgs e)
        {
            if (!(e.Row is GridViewHeaderRow) && !(e.Row is GridViewNewRow))
            {
                var rowContextMenu = new RadContextMenu();
                StyleManager.SetTheme(rowContextMenu, StyleManager.GetTheme(SamplesGrid));
                rowContextMenu.Items.Add(new RadMenuItem { Header = "Add Row" });
                rowContextMenu.Items.Add(new RadMenuItem { Header = "Delete Selected Row(s)" });
                rowContextMenu.AddHandler(RadMenuItem.ClickEvent, new RoutedEventHandler(OnMenuItemClick));
                rowContextMenu.Opened += OnMenuOpened;
                RadContextMenu.SetContextMenu(e.Row, rowContextMenu);
                MessageBox.Show("SamplesGrid_RowLoaded");
            }
        }

        private static void OnMenuOpened(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("OnMenuOpened");
            var row = ((RadRoutedEventArgs)e).OriginalSource as GridViewRow;
            if (row != null)
                row.IsSelected = row.IsCurrent = ((GridViewCell)row.Cells[0]).IsCurrent = true;
        }

Thanks much for your help,
Marco

Hi Marco,

You need to set windowless to true for the SL control - please check this thread for more info:

Hi,

I added a context menu to the header row by following exactly what you have in the Examples project. For some reason, it just shows Silverlight config. option. I even set WindowLess = true.

Please Help.
thanks

Just to add to my comment above, I am calling a web service and binding the data asynchronously, not sure if this has any impact on ContextMenu

[rb]

I just figured out...I have to add the control dynamically when binding asynchronously to data.

thanks

Right now I'm on RowLoaded ...
Thanks in advance

Could someone elaborate on how to add a context menu when loading data asynchronously?

Thank you.

Hi,

You can add the menu for the entire grid statically and show/hide or change menu items conditionally. Please check this demo for more info:
