Read-only controls
If you make any controls read-only, either by using the ReadOnly attribute or by using a WebView control, keep in mind that the same controls may also appear in bulk update and bulk resolve views. You should make the controls in those views read-only as well.
For example, there is a Comments text box (Id=txtTabComments) in the WorkManagement_WorkOrder_CommentsView view. There are also Comments text boxes, which are bound to the same property, in the WorkManagement_BulkUpdateView and WorkManagement_BulkResolve_View views. If you make the first Comments text box read-only, users will still be able to enter comments in the other two text boxes unless you make those read-only as well.
