set_selected()

The method is used to select/deselect a row on the client. It takes a single Boolean argument, specifying whether the items should be selected or not.

Example:

JavaScript

	        function GridCreated() {
	            var masterTable = $find("<%=RadGrid1.ClientID%>").get_masterTableView();
	            var dataItem = masterTable.get_dataItems()[0];
	            dataItem.set_selected(true);
	        }
