[Mohit Vijay]

Hello,

I want to set the icon property of RadMenuItem on run time, Actually, I want to change the imange, when mouse enter and also when mouse leave from that RadMenu item, so I need to set the image dynamically. Remember I am using vb.net.

Can you please provide me the code example for it?

Hi Mohit Vijay,

Check the code snippet bellow:

 <UserControl.Resources>
        <BitmapImage x:Key="defaultImage" UriSource="Dock.jpg" />
        <BitmapImage x:Key="hoverImage" UriSource="Tree.jpg" />
    </UserControl.Resources>

    <Grid x:Name="LayoutRoot">

        <telerikNavigation:RadMenu Width="500" Height="30">
            <telerikNavigation:RadMenuItem Header="File">
                <telerikNavigation:RadMenuItem Header="Open" x:Name="radMenuItem"
                        Click="RadMenuItem_Click" MouseLeave="RadMenuItem_MouseLeave"
                        MouseEnter="RadMenuItem_MouseEnter">
                    <telerikNavigation:RadMenuItem.Icon>
                        <Image Source="{StaticResource defaultImage}" Width="20" Height="20" />
                    </telerikNavigation:RadMenuItem.Icon>
                </telerikNavigation:RadMenuItem>
            </telerikNavigation:RadMenuItem>
        </telerikNavigation:RadMenu>
    </Grid>

 Private Sub RadMenuItem_MouseEnter(ByVal sender As Object, ByVal e As MouseEventArgs)
        Dim image As BitmapImage = Me.Resources("hoverImage")
        Dim imageSource As Image = radMenuItem.Icon

        imageSource.Source = image
    End Sub

    Private Sub RadMenuItem_MouseLeave(ByVal sender As Object, ByVal e As MouseEventArgs)
        Dim image As BitmapImage = Me.Resources("defaultImage")
        Dim imageSource As Image = radMenuItem.Icon

        imageSource.Source = image
    End Sub

    Private Sub RadMenuItem_Click(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs)
        RadMenuItem_MouseLeave(sender, Nothing)
    End Sub
