Hi runes,

Here is an example how to change RadMenuItem Icons in code:
This is the page.xaml

<UserControl x:Class="SilverlightApplication26.Page"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:nav="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Navigation"
        Width="400" Height="300">
    <StackPanel x:Name="LayoutRoot" Background="White">
        <RadioButton Content="Click Me to Open the RadContextMenu">
            <nav:RadContextMenu.ContextMenu>
                <nav:RadContextMenu EventName="Click" x:Name="radContextMenu1">
                    <nav:RadMenuItem Header="Item 1" />
                    <nav:RadMenuItem Header="Item 2" />
                </nav:RadContextMenu>
            </nav:RadContextMenu.ContextMenu>
        </RadioButton>
    </StackPanel>
</UserControl>

and this is the code-behind:

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media.Imaging;
using Telerik.Windows;
using Telerik.Windows.Controls;

namespace SilverlightApplication26
{
    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;
            string header = Convert.ToString(item.Header);
            if (header == "Item 1")
            {
                item.Icon = new Image() { Source = new BitmapImage(new Uri("rasterCard3D.png", UriKind.Relative)) };
            }
            else
            {
                item.Icon = new Image() { Source = new BitmapImage(new Uri("rasterCard3DMonoChrome.png", UriKind.Relative)) };
            }
        }
    }
}

Hello runes,

I'm not sure that I understand your question. What do you mean with in Loaded event?

You can add the icons in XAML or you can add them in the Page constructor. Just give Name to the contextMenu so that you have access in the code behind and after the InitializeComponent method iterate the Items of the contextMenu and set their Icon property (like in my previous post).

Let me know if you need more help.

Hello Telerik People,

Can you please convert below code for vb.net?

private void OnMenuItemClick(object sender, RoutedEventArgs e)

{

RadRoutedEventArgs args = e as RadRoutedEventArgs;

RadMenuItem item = args.OriginalSource as RadMenuItem;

string header = Convert.ToString(item.Header);

if (header == "Item 1")

{

item.Icon = new Image() { Source = new BitmapImage(new Uri("rasterCard3D.png", UriKind.Relative)) };

}

else

{

item.Icon = new Image() { Source = new BitmapImage(new Uri("rasterCard3DMonoChrome.png", UriKind.Relative)) };

}

}

Hi Mohit Vijay,

I used converter.telerik.com and below is the result I got:

Private Sub OnMenuItemClick(sender As Object, e As RoutedEventArgs)
 Dim args As RadRoutedEventArgs = TryCast(e, RadRoutedEventArgs)
 Dim item As RadMenuItem = TryCast(args.OriginalSource, RadMenuItem)
 Dim header As String = Convert.ToString(item.Header)
 If header = "Item 1" Then
  item.Icon = New Image()
 Else
  item.Icon = New Image()
 End If
End Sub

Hope this helps.

All the best,
