Assembly: System.Web (in System.Web.dll)
The ObjectDataSourceFilteringEventArgs class is used to pass data to the Filtering event handler of the ObjectDataSource object. The property provides access to the filter parameter values before the filtering operation is performed.
You should validate any filter parameter value that you receive from the client. The runtime simply substitutes the parameter value into the filter expression and applies it to the DataView object that is returned by the Select method. If you are using the FilterExpression property as a security measure to limit the number of items that are returned, you must validate the parameter values before the filtering occurs.
