SqlDataSourceFilteringEventHandler Delegate
Assembly: System.Web (in system.web.dll)
public delegate void SqlDataSourceFilteringEventHandler ( Object^ sender, SqlDataSourceFilteringEventArgs^ e )
/** @delegate */ public delegate void SqlDataSourceFilteringEventHandler ( Object sender, SqlDataSourceFilteringEventArgs e )
JScript supports the use of delegates, but not the declaration of new ones.
Parameters
- sender
The source of the event, a SqlDataSource.
- e
An SqlDataSourceFilteringEventArgs that contains the event data.
Filtering is supported when the DataSourceMode property is set to the DataSet value.
When you create an SqlDataSourceFilteringEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Consuming Events.
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.
