can control call parent & have value returned to it?

I have an ascx control, and it needs a value called 'orgID' which the parent
page will have. I want to avoid the parent page setting values in fields on
the ascx control since this violates encapsulation principles,
SO...
I want to know if InvokeMember can be used to return a value from the
parent. ie:

Type myParent = this.Page.GetTy pe();
string strOrgid = myParent.Invoke Member("GetOrgI D", System.Reflecti on...
null, this.Page, new object[]{ });

If I make GetOrgID a function on the parent that returns a string, can the
above work?
Or is there a better way for the ascx to request values from its parent.

Sort of similar to your problem, I was looking at various ways of
calling a function on my parent page from a ascx control, and settled on
the one below. I'm in VB and calling a function rather than returning a
property (and you probably want to have a property rather than a
variable).
(The page in this case is MainReport.aspx )

Dim myParent As MainReport
myParent = CType(HttpConte xt.Current.Hand ler, MainReport)
myParent.LoadFi lter()

I know how to call a func on the parent page from the ascx control... but
can that fun on the parent page RETURN a value to the ascx? Thats what i'm
looking for. Jim your LoadFilter() func, can it return a value to the
calling ascx? Or my Invoke function (shown further up in the thread), can
that return a value...

You might try looking at
Page.Context.It ems - MSDN for HttpContext Members and check out the
"Items" under Public Properties

Hope this helps. Posting is provided as Is

Nothing comes up on a search of page.context.it ems & msdn.
I don't think there is a way to get a value back from the parent page using
this tactic.
Anyone have any other way to do this. The ascx page wants a value from the
parent page...

#1 - "ascx" is a Custom control embedded inside a page. Therefore it has
access to the Page
#2 - if you convince yourself that you can't do it then you can't

I have what's probably a simple page lifecycle question related to dynamically evaluating values that are placed by a repeater and dynmically placing user controls that use those values. I'm attempting to bind a user control I've written, "ImageBox", to a repeater. The user control takes a custom property, "ContentID", that will execute a database lookup and load an image.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.
