DataBoundControl.ValidateDataSource Method

Note: This method is new in the .NET Framework version 2.0.

Verifies that the object a data-bound control binds to is one it can work with.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

protected override void ValidateDataSource (
	Object dataSource
protected void ValidateDataSource (
	Object dataSource
protected override function ValidateDataSource (
	dataSource : Object



An object set to the DataSource property.

Exception typeCondition


The object passed by the dataSource parameter is not a null reference (Nothing in Visual Basic) or a recognized type.

The ValidateDataSource method is only called in the BaseDataBoundControl class's mutator (set accessor) for the DataSource property. The DataBoundControl class checks the type of the object that is set for the DataSource property to ensure that it is an instance of the IDataSource, IListSource, or IEnumerable interface.
