Just a clue here... There is a concept of Owner and OwnedForm in MDIParent and Child Forms, just check whether they can be used..
Those are properties of forms.

If you use the MDI architecture, a Form whose MDIParent is set (i.e., a child Form) cannot have its Owner property set: those are mutually exclusive "states." You can use a Form in an MDI app which has its Owner set to the Main Form, however, although I would not recommend such a design.

I think you are making a serious mistake in your design: MDI is not meant to have any Controls on the MDI Form itself. Yes, you can drag-drop Controls onto the MDI Form, but any child Forms you create will always be "under" them in the z-order, and you will get a visual mess !

MDI is a deprecated architecture, and I'd encourage you ... if you can ... to switch to using something like a TabControl on a Main Form, where each TabPage in the TabControl can be one web-page ... or use some other design-model.

SQL

System.Web.UI.UpdatePanel u = (UpdatePanel)((ContentPlaceHolder)((MasterPage)SenderPageName.Master).FindControl("ContentPlaceHolder1")).FindControl("PanelName");

Use This Syntax To Find Control On Master Page.
