SL4 ContextMenu: is it possible set MenuItem.Icon programmatically?

Question

i try do this:

Icon = new Rectangle() {
   Width = 16, Height = 16, Fill = new ImageBrush() {
      ImageSource = new BitmapImage(new Uri(@"/Sys2.SL.Core;component/Assets/png/16x16/delete.png",
         UriKind.RelativeOrAbsolute))
}

(icon is not visible)

,try this:

Style = Application.Current.Resources["MenuItemDeleteStyle"] as Style

where MenuItemDeleteStyle:
    <Style x:Key="MenuItemDeleteStyle" TargetType="inputToolkit:MenuItem">
        <Setter Property="Icon">
            <Setter.Value>
                <Rectangle Width="16" Height="16">
                    <Rectangle.Fill>
                        <ImageBrush ImageSource="/Sys2.SL.Core;component/Assets/png/16x16/delete.png"/>
                    </Rectangle.Fill>
                </Rectangle>
            </Setter.Value>
        </Setter>
    </Style>
(Unhandled Error in Silverlight Application)

i cannot find what is wrong ((
there are two ContextMenu for dataform (one for readonly and one for edit modes), and ContextMenuService.SetContextMenu(dataForm, <ctxMenu4actualDfMode>) is using to switch between them - thats why cann't use xaml...

p.s.excuse my English :)

Answer 1

workaround is to place ImageBrush into UserControl.Resources

<UserControl.Resources>
    <ImageBrush x:Key="DeleteImageBrush" ImageSource="/Sys2.SL.Core;component/Assets/png/16x16/delete.png"/>

and then, in code

Icon = new Rectangle() { Width = 16, Height = 16, Fill = this.Resources["DeleteImageBrush"] as ImageBrush } (icon is visible)

but, if place it into app resources (another assembly), its not work

Icon = new Rectangle() { Width = 16, Height = 16, Fill = Application.Current.Resources["DeleteImageBrush"] as ImageBrush } (icon is not visible)

why? what am i missing?

If you still haven't found a workaround then why not try the context menu from this project instead:

In fact it is quite easy:

1. Create a bitmapimage

                Dim bmp As BitmapImage
                bmp = New BitmapImage(New Uri("/xxx;component/Images/icons/ContextMenu/Copy16.png", UriKind.Relative))

2. Add a image control (XAML) and add the bitmapimage as its source

               Dim img As Image = New Image()
                img.Source = bmp

3. Add the image control as the icon content.
                MenuItem.Icon = img

                ctxMenu.Items.Add(MenuItem)
