Hi all,

I wrote 2 user custom controls. Now I have a need to put the second user
custom control "inside" the first one.

For example, if user custom control 1 returns a table with a bunch of rows,
I need my user custom control 2 to be in one of the cells within the table.

When I alter custom control 1 to create a tag for custom control 2, the end
result HTML is the tag itself, not the rendered custom control 2.

Does anyone know how to do what I'm trying to explaing here?

Thanks,
Russ

Yeah.

Now I'm taking a different approach and I'm still having trouble.

I'm overriding one of the functions in control #1 that generates the HTML,
and I'm programmatically creating control #2. But control #2 is still not
getting rendered. Here's the code. Remember, this is in the overridden
function within control #1:

Dim pg As System.Web.UI.Page = Me.DrillDownBox.Page
Dim itb As UserControls.InquiryThreadBox = New UserControls.InquiryThreadBox
itb.ID = "itb" & dr.Item("WorkID").ToString()
itb.Width = Unit.Pixel(500)
itb.HyperlinkInquiries = True
itb.InquiryPage = "note.aspx"
itb.DataSource = GetAllRelatedInquiries(10114)
itb.DataBind()
Return itb.GenerateHTML

My thinking is that since THIS control is currently getting rendered, I'm
way beyond trying to add controls to the page object. So that GenerateHTML
function there at the end should return everything that control #2 WOULD
have generated if it had just been put on a page. Instead, I'm "Return"ing
that HTML generated by control #2 to control #1's HTMLTextWriter.

Can anyone figure out why nothing ever gets rendered for control 2? The
thing ALWAYS returns HTML, whether there is data in the data source or not.

Thanks!

Little, Ambrose
Have you tried just creating the control and adding it to the child controls
collection when you control #1 is created?
