BaseDataBoundControlDesigner.PreFilterProperties Method
Used by the designer to remove or add additional properties for display in the Properties grid or to shadow properties of the associated control.
Namespace: System.Web.UI.Design.WebControls
Assembly: System.Design (in System.Design.dll)
Parameters
- properties
- Type: System.Collections.IDictionary
The IDictionary containing the properties to filter.
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 or remove properties from the Properties grid.
For the BaseDataBoundControl class, the PreFilterProperties shadows the DataSource property of the control. It makes a copy of the attribute array of the DataSource, and then adds these attributes to the shadowed property. It sets the Browsable attribute of the shadowed DataSource property to false unless the Browsable attribute of the DataSourceID property of the control is already set to true.
Notes to InheritorsOverride the PreFilterProperties method to add properties to or change attributes of properties in the design-time property collection. Be sure to call the base method before performing other processing.
