This is the correct place for this question. You are doing the right check, although it looks like you are checking the IsOpen value for a tool with a different key than the tool used as the context menu for the control. If I am wrong and the value is still always returning False, it might be a bug and I would recommend submitting the issue to the support group: http://es.infragistics.com/gethelp. You might be able to work around this by handling the BeforeToolDropdown and AfterToolCloseup events of the toolbars manager. The SourceControl property of these event args will be the control for which the menu is showing as a context menu (or null if the menu is not displaying as a context menu).
