AccessDataSourceDesigner.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 them from, the Properties grid.
For the AccessDataSource control, the PreFilterProperties method creates the design-time DataFile property to shadow the DataFile property of the control.
Notes to Inheritors: Override the PreFilterProperties method to add properties to the design-time property collection or change their attributes. Be sure to call the base method before performing other processing.The following code example shows how to override the PreFilterProperties method to make the ConnectionString property read-only and visible in the Properties grid.
This code example is part of a larger example provided for the AccessDataSourceDesigner class.
