TcxGridCardView.OnRowExpanding Event

Fires when a category row is about to be expanded.

Declaration

property OnRowExpanding: TcxGridCardRowChangingEvent read; write;

Remarks

The OnRowExpanding event fires when the category row starts expanding either by end-user action or via code (by setting the row’s Expanded property to True).

Implement the OnRowExpanding event handler to provide custom behavior when the category row is about to be expanded. For instance, you can handle this event to prevent the category row from unnecessarily expanding.

The Sender parameter specifies the Card View to which the category row belongs;

The ARow parameter specifies the category row that is about to be expanded;

The AAllow parameter specifies whether ARow will be expanded. Set the AAllow parameter to False to prevent ARow from expanding.
