[DXCategory("Behavior")] public event RowAllowEventHandler CardCollapsing
<DXCategory("Behavior")> Public Event CardCollapsing As RowAllowEventHandler
The CardCollapsing event's data class is RowAllowEventArgs. The following properties provide information specific to this event:
|Allow||Gets or sets a value specifying whether the current operation is allowed.|
|RowHandle||Gets the row’s handle (position). For the ColumnView.RowUpdated event, this property specifies the previous handle (position) of the currently processed row. NewItemRowHandle value when a new row is added. Inherited from RowEventArgs.|
The CardCollapsing event is raised when an attempt is made to collapse a card (regardless of whether this is being performed in code or by an end-user at runtime). The card is identified by the RowEventArgs.RowHandle parameter. To prevent it from being collapsed set the RowAllowEventArgs.Allow parameter to false.
