HOW-TO: Datagrid: Read contents of template (textbox) column in ImgBtnClick event

[DAC]

Hello,
I have a template column of my DataGrid filled with textboxes (one textbox
inside each cell/row).
I have set myTextBox.ID = "myBox" in InstantiateIn function,
so all the controls have the same name (?).

How do I get the values the user entered in each textbox inside a
ImageButtonClick event?
I'm trying to use DataGrid.FindControl, but it doesn't work.

Any ideas?

Thanks,
Daniel
