Simple question: e.Item.Cells(0).Controls­(0)

[davidfox789]

I am new at this.. probably not proficient enough to even consider
myself a Newbie yet.

I have a DataGrid with Template columns. After the user edits a field
in the DataGrid and presses Update, the UpdateCommand code executes no
problem. However...

Normally I read the newly edited contents of a cell thusly:

Dim tb As TextBox
tb = CType(e.Item.Cells(1).Controls(0), TextBox)

However! A DataGrid I created today will only work if I reference
Controls(1) rather than Controls(0):

Dim tb As TextBox
tb = CType(e.Item.Cells(1).Controls(1), TextBox)

Could someone please shed some light on how an attribute can "move
around" inside a control, in this case from position 0 to position 1?

I don't want them moving around after I'm done.

The better way is to use

Dim tb As TextBox = CType(e.Item.FindControl(textbox_ID), TextBox)

Thanks for the reply.

I think I tried something like that before... I think I had the name in
quotes though (which may be similar to what you mean, if textbox_ID
above is a string... man I'm such a newbie at this) Anyhoo I will try
that in the future.

FWIW, is there a way to probe the contents of
e.Item.Cells(0).Controls­() programatically? (I tried QuickWatch -
there's so much detail, I don't know what I'm looking for.)

Maybe something like the following psedocode? ...

for each control in e.item.cells(0).controls()
display name and type
next

Should try this think instead of above way
Dim txt as textbox
txt = CType(e.item.cell(1).FindControl(""id of textbox"),textbox)

This method works well for all cases.
