Finding a control inside an <itemtemplate >

[Jim in Arizona]

How do I find a control within a datalist itemtemplate from a sub
procedure that isn't a normal called procedure from a datalist (like the
update, edit, or cancel procedures)?

For instance, normally you find a control and access it's properties and
methods, like so:

Sub Update(ByVal sender As Object, ByVal e As DataListCommand EventArgs)

Dim txtPosted As New TextBox
txtPosted = e.Item.FindCont rol("txtPosted" )

End Sub

How could I do this using a different procedure, like:

Sub AnotherProcedur e()
End Sub
TIA,
Jim

The DataList exposes Items collection. navigate to the required item and do
the same FindControl.

Enable trace in the page. Load the page and read the trace to identify the
control in the control tree hierarchy. We have to use the FindControl method
on each object in that hierachy for those instances when objects are deeply
nested into templates. Don't forget to cast the found object to the proper
type.

Could you please provide an example? I've looked around the net and
can't seem to find one anywhere.

I still consider myself a newbie when it comes to this stuff and am just
now starting to harness the power of the datalist control.

After some experimentation and trying to follow examples at this location:
http://quickstarts.asp.net/QuickStar.../datalist.aspx

I have come up this this code:

Sub HideOrShowButto n()

Dim i As Integer
Dim lblDate As New Label
Dim btnUpdate As New Button
For i = 0 To dlNotes.Items.C ount - 1

lblDate = dlNotes.Items(i ).FindControl(" lblDate")
btnUpdate = dlNotes.Items(i ).FindControl(" btnUpdate")

If lblDate.Text = "1/4/2007 10:15:00 AM" Then
btnUpdate.Visib le = True
Else
btnUpdate.Visib le = False
End If
Next

End Sub

This is unrefined, but is a good start to what I'm hoping for. My goal
is to make visible or invisible a button based on the original post time
of the db record.

If anyone can think of a better way of doing this that's not overly
complicated, please post!

Thanks to those who replied.

This code is absolutely fine.
