Public Event CardExpanding As RowAllowEventHandler
The CardExpanding event's data class is RowAllowEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| 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 CardExpanding event is raised when attempting to expand 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 expanded set the RowAllowEventArgs.Allow parameter to false.
