Public Overrides Function EditValue (context As ITypeDescriptorContext, provider As IServiceProvider, value As Object) As Object

An ITypeDescriptorContext object used to acquire context information.

An object implementing the IServiceProvider through which editing services can be obtained.

value: Object

The object to edit the value for.

Remarks

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.
