The EditValue method extracts the associated data source control and the data source control designer that is associated with that control from the context parameter. The supported data source controls include the ObjectDataSource and SqlDataSource controls, with their corresponding ObjectDataSourceDesigner and SqlDataSourceDesigner designers.

Once the data is extracted, the EditValue calls back to the data source control designer to display an editing dialog box that is used to edit a ParameterCollection object that is referenced by one of the Parameters properties of the data source control.
