HierarchicalDataBoundControlDesigner Class

Provides design-time support in a designer host for the HierarchicalDataBoundControl control.

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

public ref class HierarchicalDataBoundControlDesigner : public BaseDataBoundControlDesigner

In a designer host, when the user switches from Source to Design view, the markup source code that describes a control that is derived from the HierarchicalDataBoundControl abstract class is parsed and a design-time version of the control is created on the design surface. When the user switches back to Source view, the design-time control is persisted to markup source code and edited into the markup for the Web page. The HierarchicalDataBoundControlDesigner class provides design-time support for controls that are derived from the HierarchicalDataBoundControl in a designer host.

The HierarchicalDataBoundControlDesigner class properties provide the following functionality:

The HierarchicalDataBoundControlDesigner class methods provide the following functionality:

The following code example shows how to extend the HierarchicalDataBoundControlDesigner class to change the appearance of controls that are derived from the HierarchicalDataBoundControl control at design time.

The example derives the MyHierarchicalDataBoundControl class from the HierarchicalDataBoundControl. The MyHierarchicalDataBoundControl class is simply a copy of the HierarchicalDataBoundControl. The example also derives the MyHierarchicalDataBoundControlDesigner class from the HierarchicalDataBoundControlDesigner class and places a DesignerAttribute object for the MyHierarchicalDataBoundControlDesigner on the MyHierarchicalDataBoundControl class.

The MyHierarchicalDataBoundControlDesigner overrides the PreFilterProperties method to make the NamingContainer property visible in the Properties grid at design time. It overrides the GetDesignTimeHtml method to generate the markup for a placeholder if the design time markup is nullptr or Empty, or if the design-time markup is an empty <span> block (that is, if there is no inner markup between the <span> and </span> tags).

No code example is currently available or this language may not be supported.
