one general issue ..just giveme an idea.. i created my usercontrol..i.e grid bottom is having sime links(my user control).i added one link as "new".when i clicked on new link i want to open the corresponding window.i mean if i used thet grid for enter address(addressform) when i clicked on new link Addesentrywindow should open.and if used my contol in some survey form.when i clicked on new surveyentry form should open.like that what is the better way to procede these issue.

 thanks,

Mike, thank you for your answer. If possible could you look at stack trace below? I found that UIRoleOnMenus and UIRoleOnRibbonGroups properies are null after adding control to the ribbon. But when I use the same code for the PopupControlContainerTool object these proprties are not null. Is it possible that the reason of the exception is in UIRole properties? BTW I receive 'group' variable as RibbonTab tab = ultraToolbarsManager1.Ribbon.Tabs["ribbon1"]; RibbonGroup group = tab.Groups["ribbonGroup1"]; Thanks in advance.
