Adding menu items to the default RadVirtualGrid context menu

In order to add custom menu items to the default context menu, you should create menu item instances in the ContextMenuOpening event handler and add them to the VirtualGridContextMenuOpeningEventArgs.ContextMenu.Items collection:

Adding items to the default RadVirtualGrid context menu:

C#

        
private void Add_ContextMenuOpening(object sender, VirtualGridContextMenuOpeningEventArgs e)
{
    RadMenuItem customMenuItem = new RadMenuItem();
    customMenuItem.Text = "Custom Data Operation";
    RadMenuSeparatorItem separator = new RadMenuSeparatorItem();
    e.ContextMenu.Items.Add(separator);
    e.ContextMenu.Items.Add(customMenuItem);
}

VB.NET

Private Sub Add_ContextMenuOpening(sender As Object, e As VirtualGridContextMenuOpeningEventArgs)
    Dim customMenuItem As New RadMenuItem()
    customMenuItem.Text = "Custom Data Operation"
    Dim separator As New RadMenuSeparatorItem()
    e.ContextMenu.Items.Add(separator)
    e.ContextMenu.Items.Add(customMenuItem)
End Sub
