Dashboard.CustomFilterExpression Event
Allows you to include WHERE clauses into DashboardSqlDataSource queries.
Namespace: DevExpress.DashboardCommon
Assembly: DevExpress.Dashboard.v18.2.Core.dll
Declaration
Event Data
The CustomFilterExpression event's data class is DashboardCustomFilterExpressionEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| 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. |
| TableName | Gets the name of a data table to which the DashboardCustomFilterExpressionEventArgs.FilterExpression applies. |
Remarks
The CustomFilterExpression event fires for each SelectQuery within DashboardSqlDataSource (the SqlDataSource.Queries property) and allows you to include a WHERE clause to a query at runtime using the CustomFilterExpressionEventArgs.FilterExpression event parameter. If filtering is already applied to the SQL query, CustomFilterExpressionEventArgs.FilterExpression returns a corresponding filter criteria.
Note
The CustomFilterExpression event is not raised for custom SQL queries and stored procedures.
