System_CAPS_pubmethodDataBindControl(IDesignerHost, Control)

Resolves design-time data-binding for the specified control.(Overrides DataBindingHandler.DataBindControl(IDesignerHost, Control).)


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

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 : 
    // Override the DataBindControl to set property values in  
    // the DataBindingCollection at design time.
    public override void DataBindControl(IDesignerHost designerHost, 
        Control control)
        DataBindingCollection bindings = 
        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
