SqlDataSourceFilteringEventArgs Class
Assembly: System.Web (in system.web.dll)
The SqlDataSourceFilteringEventArgs class is used to pass data to the Filtering event handler of the SqlDataSource control. The ParameterValues property provides access to the filter parameter values before the filtering operation is performed. You can cancel the Select method by setting the Cancel property of the ObjectDataSourceFilteringEventArgs to true. Filtering is supported when the DataSourceMode property is set to the DataSet value.
The following code example demonstrates how to retrieve data from the Northwind database and filter it using a FilterExpression and FilterParameters. The FilterExpression of the SqlDataSource is applied anytime the Select method is executed to retrieve data. In this example, the FilterExpression contains a placeholder for a filter parameter, which is contained in the FilterParameters collection. In the Filtering event, the filter parameter is displayed in a Label control.
