SelectionMode: SelectionModeType;
The SelectionMode property determines the mode of selecting component elements.
Default mode of a multiple selection: SelectionModeType.MultiSelectStandard.
Executing the example requires a form with the Button1 button, the RdsDictionaryBox component named RdsDictionaryBox1, and the UiRdsDictionary component that is a data source for RdsDictionaryBox1. Example is a handler of the OnClick event for a button.
Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Begin
RdsDictionaryBox1.SelectionMode := SelectionModeType.SingleSelect;
End Sub Button1OnClick;
After executing the example mode of a singular selection is enabled in the RdsDictionaryBox1 component.
