if (UserRights().Export.ToLower() == "false")
	regDataGrid.LayoutSettings.AllowExport = ISNet.WebUI.WebGrid.Export.No;
else
	regDataGrid.LayoutSettings.AllowExport = ISNet.WebUI.WebGrid.Export.Yes;

For your information, I recommend you to put this syntax on OnInitializeLayout event.

Hope this helps.
