First off, I realize most of this can also be done using ItemTemplates. If what I'm trying to do simply isn't possible, I will consider using them instead.
Here are the basics of my dilemma:
I have a GridView in the ASPX page that is loaded in the CodeBehind. Each row contains a couple of buttons that trigger the OnRowCommand event. When someone clicks the "Edit" button, I create a TextBox object and add it to the Controls collection of a particular cell.
This works fine.
The problem is, when the person clicks the "Save" button, OnRowCommand is triggered again but the cell is registering 0 items in the Controls collection. I'm pretty sure this is happening before a PostBack so I'm not sure why I can't access the TextBox control.
I checked after initially adding the TextBox and it shows 1 Control in the cell. Somewhere between loading the page with the textboxes and clicking the button, these controls have gone missing. Google wasn't much help. Any ideas?
You are dynamically creating textboxes so you have to re-bind your grid on each post back, give your textboxes and id (always the same) and re-attach any event handlers.
