public event DashboardCustomFilterExpressionEventHandler CustomFilterExpression
Public Event CustomFilterExpression As DashboardCustomFilterExpressionEventHandler
The CustomFilterExpression event's data class is DashboardCustomFilterExpressionEventArgs. The following properties provide information specific to this event:
|DataSource||Obtains the data source that provides data for the dashboard. Inherited from DataSourceEventArgs.|
|FilterExpression||Gets or sets the filter expression that defines a WHERE clause included in the SQL query.|
CustomFilterExpression event fires for each SelectQuery within the SqlDataSource.Queries collection. The e.FilterExpression property allows you to include a WHERE clause into a query at runtime. If a filter is already applied to the SQL query,
e.FilterExpression returns the corresponding filter criteria.
For more information on how to create filter criteria as a CriteriaOperator object, refer to the following help article: Simplified Criteria Syntax.
The CustomFilterExpression event is not raised for custom SQL queries and stored procedures.
