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
