Setting MenuItem icon through style installer

Question

<Style x:Key="ContextMenuItemStyle" TargetType="{x:Type MenuItem}">
    <Setter Property="Icon" Value="{Binding Icon}" />
    <Setter Property="Header" Value="{Binding Text}" />
    <Setter Property="ItemsSource" Value="{Binding Children}" />
    <Setter Property="Command" Value="{Binding Command}" />
</Style>

setting it into code as follows:

Uri refreshUri = new Uri("..\\Resources\\Refresh16.bmp",UriKind.Relative);
BitmapImage refreshIcon = new BitmapImage();
refreshIcon.UriSource = refreshUri;

Icon does not appear, any hints?

Answer 1

If this refreshIconis the source of your property Icon, you may need to either invoke NotifyPropertyChanged("Icon")after your sample code (and implement the interface INotifyPropertyChanged) or declare Iconhow DependencyProperty.

Here is a link to more information about the interface INotifyPropertyChanged.

Ahh, I see your problem ... try setting the property Iconto Imageand bind to the source Image:

<Setter Property="Icon">
    <Setter.Value>
        <Image Source="{Binding Icon}" />
    </Setter.Value>
</Setter>

"" xaml :

<Setter Property="Icon">
    <Setter.Value>
        <Image Source="/ProjectName;component/Images/IconName.ico" />
    </Setter.Value>
</Setter>

    <Image x:Key="Icon" Source="/ProjectName;component/Images/IconName.ico" x:Shared="false"/>
    <Style x:Key="MenuItem">
        <Setter Property="MenuItem.Header" Value="Header Text"/>
