Failed to create a 'Path' from the text '(RadButtonOnImage:RadButtonImage.Image)'

Question

I create a attach property for my RadButton to set a image inside Button content But i get this exception in design time in Visual Studio 2010. In Blend 4 i does not show any error and at Run time it`s working fine.

Attach Property :

namespace SmartSoft.GTS.RadButton
{
public class RadButtonImage
{
     public static readonly DependencyProperty ImagePropery;
     public static ImageSource GetImage(DependencyObject obj)
     {
         return (ImageSource)obj.GetValue(ImagePropery);
     }
     public static void SetImage(DependencyObject obj,ImageSource Value)
     {
         obj.SetValue(ImagePropery,Value);
     }
     static RadButtonImage()
     {
         ImagePropery = DependencyProperty.RegisterAttached("Image", typeof(ImageSource), typeof(RadButtonImage), new PropertyMetadata((ImageSource)null));
     }
   }
}

XAML :

  xmlns:RadButtonOnImage="clr-namespace:SmartSoft.GTS.RadButton"

    <Style x:Key="ImageOnRadButton" TargetType="{x:Type telerik:RadButton}">
        <Setter Property="FontSize" Value="13.333"/>
        <Setter Property="ContentTemplate">
            <Setter.Value>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <Image Margin="5,0,5,0" HorizontalAlignment="Center" VerticalAlignment="Center"  Source="{Binding (RadButtonOnImage:RadButtonImage.Image), RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:RadButton}}}"/>
                        <TextBlock Text="{TemplateBinding Content}" TextAlignment="Center" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="0,0,5,0"/>
                    </StackPanel>
                </DataTemplate>
            </Setter.Value>
        </Setter>
    </Style>

  <telerik:RadButton Content="New" RadButtonOnImage:RadButtonImage.Image="Images/Buttons/Clear.png" Style="{DynamicResource ImageOnRadButton}"/>

Where i am doing wrong ?

Thank `s for help.

I also have this issue in V2012.3. The issue is that the XAML parser in VS does not approve of the parenthesis in the Path, even though it does work when compiled. — tofutim, May 15 '13 at 14:59
In my case it is: sllb:SearchTextBox.FilteredFieldNames="{Binding (sllb:SearchTextBox.FilteredFieldNames), RelativeSource={RelativeSource TemplatedParent}}" - the parentheses are the issue and must some how be escaped to work. — tofutim, May 15 '13 at 15:05
@tofutim Does it stop giving you design-time errors if you just add `Path=` to your binding, like [this answer suggests](http://stackoverflow.com/a/5832247/302677)? — Rachel, May 15 '13 at 15:08
@Rachel It works! (I just had to rebuild to see the change.) — tofutim, May 15 '13 at 15:25
Actually, now it doesn't work again. I might have just fooled myself by forgetting to uncomment out the Style code. — tofutim, May 15 '13 at 17:56
@tofutim Perhaps you should post a new question with your problem, since it doesn't appear to be the same as this one? — Rachel, May 16 '13 at 17:58

When binding to an attached property in WPF 4.0 or below, you have to actually use the Path property to avoid getting design-time errors.

<Image Source="{Binding Path=(RadButtonOnImage:RadButtonImage.Image), ...}" />

The Path property is not needed in WPF 4.5 and above.

I Agree. From a clarity standpoint, the code is better in this instance if you include the `Path=` anyway. Give her the bounty! – Rob Perkins May 16 '13 at 17:51
