The following code example creates a class, named CustomHyperLinkDataBindingHandler, which derives from the HyperLinkDataBindingHandler class. It resolves design-time data binding for the CustomHyperLink class using the DataBindControl method.

// Derive a class from the HyperLinkDataBindingHandler. It will  
// resolve  data binding for the CustomHyperlink at design time. 
public class CustomHyperLinkDataBindingHandler : 
    HyperLinkDataBindingHandler
{
    // Override the DataBindControl to set property values in   
    // the DataBindingCollection at design time. 
    public override void DataBindControl(IDesignerHost designerHost, 
        Control control)
    {
        DataBindingCollection bindings = 
            ((IDataBindingsAccessor)control).DataBindings;
        DataBinding imageBinding = bindings["ImageUrl"];

           // If Text is empty, supply a default value. 
        if (!(imageBinding == null))
        {
            CustomHyperLink hype = (CustomHyperLink)control;
            hype.ImageUrl = "Image URL.";
        }

        // Call the base method to bind the control. 
        base.DataBindControl(designerHost, control);
    } // DataBindControl
} // CustomHyperLinkDataBindingHandler
