HierarchicalDataBoundControlDesigner.PreFilterProperties Method
Assembly: System.Design (in system.design.dll)
protected void PreFilterProperties ( IDictionary properties )
protected override function PreFilterProperties ( properties : IDictionary )
Not applicable.
Parameters
- properties
A collection implementing the IDictionary of the added and shadowed properties.
Control designers use methods that are derived from the ComponentDesigner.PreFilterProperties method to shadow various control properties with corresponding design-time properties that the designer implements, and to add properties to or remove properties from the Properties grid.
For controls that are derived from the HierarchicalDataBoundControl class, the PreFilterProperties method creates design-time properties to shadow the DataSource and DataSourceID properties.
Notes to Inheritors: Override the PreFilterProperties method to add properties to or change the attributes of properties in the design-time property collection. Be sure to call the base method before performing other processing.The following code example shows how to override the PreFilterProperties method in a class that is inherited from the HierarchicalDataBoundControlDesigner class to change the Properties grid of the HierarchicalDataBoundControl control at design time. The example makes the NamingContainer property visible in the Properties grid.
