CustomizeFilterExpressionEventArgs is the data class for the following events:

• SqlDataSource.CustomizeFilterExpression

Remarks

The SqlDataSource.CustomizeFilterExpression event is fired when the SqlDataSource sends a query to reload data from the server (for instance, on the SqlDataSource.Fill method call). Use the event parameter’s CustomizeFilterExpressionEventArgs.FilterExpression property to specify a filter expression to be included in this query as a WHERE clause.

The filter expression should be represented by the CriteriaOperator descendant. To learn how to create the appropriate object, see Creating Criteria. Use the CustomizeFilterExpressionEventArgs.QueryName property to identify the query for which the event has been raised.

Note

The SqlDataSource.CustomizeFilterExpression event is fired only for queries represented by the TableQuery class.

You can also handle the SqlDataSource.ConfigureDataConnection event to specify connection parameters on the fly.
