Customize Checkbox Into An Image Checkbox

Question

Hi

I am working on a custom checkbox control which can take Content as plain text/image/both. I understand this can be easily acheived using XAML but what i need is a property ContentImage which when set will display both Image & Content. I inherited this control from checkbox and trying to do this custom implementation but nothing shows up.

public ImageSource ContentImage 
    {
        get 
        { 
            return contentImage; 
        }
        set 
        { 
            contentImage=value;


        }
    }


private void SetContentTemplate()
    {



        DataTemplate contentTemplate = new DataTemplate();



        StackPanel sp = new StackPanel();


        Image contentImage = new Image();
        contentImage.Source = ContentImage;
        sp.Children.Add(contentImage);

        TextBlock contentText = new TextBlock();
        contentText.SetBinding(TextBlock.TextProperty, Content.ToString());
        sp.Children.Add(contentText);


        contentTemplate.Resources.Add(sp, null);


        this.ContentTemplate = contentTemplate;

    }
