DashboardDesigner.SetMasterFilter(String, Object) Method

Selects required elements by their values in the specified master filter item.

Namespace: DevExpress.DashboardWin

Assembly: DevExpress.Dashboard.v22.1.Win.dll


public void SetMasterFilter(
    string dashboardItemName,
    object values


Name Type Description
dashboardItemName String

A String that specifies the component name of the master filter item.

values Object

Values that will be used to select elements in the master filter item.



The method fires the InvalidOperationException if master filtering is disabled in the specified dashboard item (the MasterFilterMode property is set to None). The exception message text is a localizable string which can be obtained by the MessageInteractivityOperationNotAvailable identifier.


The following example demonstrates how to set master filter in the Dashboard Viewer control.

The Dashboard Viewer control loads a dashboard with two master filter items - the Grid and Range Filter dashboard items. The Chart item displays the filtered data.

The DashboardViewer.ConfigureDataConnection event is handled to specify the Extract Data Source filename. The DashboardViewer.CustomizeDashboardTitle event handler creates the command button that executes the application’s SetMasterFilterMethod procedure.

The SetMasterFilterMethod procedure uses the DashboardViewer.SetMasterFilter method to select the rows in the Grid dashboard item. The DashboardViewer.SetRange method selects the range in the Range Filter dashboard item.

This example also demonstrates how to handle the DashboardViewer.MasterFilterSet and DashboardViewer.MasterFilterCleared events.
