ASPxGridBase.SelectionChanged Event
Fires after the selection has been changed.
Namespace: DevExpress.Web
Assembly: DevExpress.Web.v19.1.dll
Declaration
Event Data
The SelectionChanged event's data class is EventArgs.
Remarks
The grid (ASPxGridView, ASPxVerticalGrid, ASPxCardView) allows end users to select/deselect multiple rows using the Select command item or in code using the following APIs:
- The ASPxGridView.Selection property.
- The ASPxCardView.Selection property.
- The ASPxVerticalGrid.Selection property.
Handle the SelectionChanged event to respond to a selection change.
Note
If the ASPxGridBehaviorSettings.ProcessSelectionChangedOnServer property is set to false, the grid fires a client SelectionChanged event (ASPxClientGridView.SelectionChanged, ASPxClientCardView.SelectionChanged, ASPxClientVerticalGrid.SelectionChanged) on the client side without a postback to the server. Set this property to true to finally process the selection on the server side and use the SelectionChanged event.
