I'm trying to disable or hide the toolbar buttons of a RadGrid on PageLoad, using the following code as suggested in one of the answers from http://www.telerik.com/forums/enable-disable-add-edit-button-in-rad-grid
radGrid.MasterTableView.CommandItemSettings.ShowAddNewRecordButton = false;
However, the buttons keep visible and working after this. Why? And how can I fix this?
