HyperLinkDataBindingHandler Class

Provides a data-binding handler for a hyperlink property.

Namespace: System.Web.UI.Design
Assembly: System.Design (in system.design.dll)

public class HyperLinkDataBindingHandler : DataBindingHandler
public class HyperLinkDataBindingHandler extends DataBindingHandler
public class HyperLinkDataBindingHandler extends DataBindingHandler
Not applicable.

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
