Itemplate viewstate

[Amine]

Hello,
I am trying to create textbox control dynamically into a datagrid.
I do not know the number of columns until run time so I thought I could use
template columns dynamically and add them into the datagrid.
This works fine, but on post back all the data in the datagrid disappears.
Any idea why? I have the bad feeling that the view state has something to
do with it.
I do have viewstate enabled.
Note: I am implementing the Itemplate interface and I have Implemented the
InstantiateIn mehod.
Thanks!

Controls which are created dynamically must be recreated dynamically on
postback in order to exist.

One solution is to use the OnItemCreated even to create the controls:

Another might be to use Denis Bauer's free dynamic control placeholder,
which might do the trick:
