Dynamic usercontrol can't get values of the checkboxes

2 New Member

Hi all,

I have:
1. I have a place holder
2. I have a usercontrol which has just a datagrid in it.
3. I get data from the database and if get different categories.
4. I bind the datagrid with each category. I do not know how many categories will be.
5. The datagrid has a checkbox column (bound)
6. Once bound, I add the datagrid into the placeholder one by one.
--------------------------------------------------------------
Issue
1. Even though when i try to change the ID of the datagrid, it does not get changed, however, the controls within the datagrid do have the changed id. Hence, I get multiple <html> snippets with same ID.
2. Initially I was losing the placeholder upon postback. But then I came across an article that I need to rebuild the placeholder contents everytime in Page_Init. Which works fine now. THE ISSUE is that, upon reload, I lose all the checked items!!!

Please HELP!

Well if you rebuild the placeholder then you need to rebuild everything that's in it also. The way that works is the view state has all the info needed to keep the same state of the page after post back. If you rebuild the controls then how is it going to know where to put the checked values. I would either find another way of doing what your doing or loop through the Request.Forms.AllKeys collection and set the checkboxes one by one. Why don't you post what you trying to do so we can maybe suggest a different way of doing it. Hope this helps.
