Hi runes,

Here is a simple example demonstrating one possible solution to add menu items dynamically on MeunItem Click event.

This is the page.xaml:

<UserControl x:Class="SilverlightApplication30.Page"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:core="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
    xmlns:nav="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.navigation"
    xmlns:local="clr-namespace:SilverlightApplication30;assembly=SilverlightApplication30">
    <Grid>
        <Button Content="Click Me" VerticalAlignment="Center">
            <nav:RadContextMenu.ContextMenu>
                <nav:RadContextMenu EventName="Click" x:Name="radContextMenu1">
                    <nav:RadMenuItem Header="Click me to add more items" />
                </nav:RadContextMenu>
            </nav:RadContextMenu.ContextMenu>
        </Button>
    </Grid>
</UserControl>

and this is the code-behind:

using System.Windows;
using System.Windows.Controls;
using Telerik.Windows;
using Telerik.Windows.Controls;

namespace SilverlightApplication30
{
    public partial class Page : UserControl
    {
        public Page()
        {
            InitializeComponent();
            radContextMenu1.AddHandler(RadMenuItem.ClickEvent, new RoutedEventHandler(OnMenuItemClick));
        }

        private void OnMenuItemClick(object sender, RoutedEventArgs e)
        {
            RadRoutedEventArgs args = e as RadRoutedEventArgs;
            RadMenuItem item = args.OriginalSource as RadMenuItem;
            RadMenuItem item1 = new RadMenuItem() { Header = "Dynamic 1" };
            RadMenuItem item2 = new RadMenuItem() { Header = "Dynamic 2" };
            item.Items.Add(item1);
            item.Items.Add(item2);
        }
    }
}

Note that you will need references toTelerik.Windows.Controls and Telerik.Windows.Controls.Navigation assemblies.

Let us know if you need more help.

Hi,

I'm afraid that you cannot create Silverlight components server-side. You can check however this demo to know more how to generate context menus dynamically on the Silverlight client.

thanks for the response,

I am not using any silverlight component. it is just normal telerik:RadContextMenu on  telerik:RadGrid.  for ASP.net web application.
