Should I add some code in the Form_Loading event that checks what groups the current user is a member of? If so, how would I prevent the form from loading? So far the code I have doesn't seem to work. SPGroupCollection grpCol = SPContext.Current.Web.CurrentUser.Groups; try { SPGroup group = grpCol["Restricted"]; // if this doesn't throw an exception, they are not part of that group, so exit return; } catch (Exception ex) { // if exception is thrown, they don't belong to that group, so continue }
