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! 1  1696

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.A llKeys 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.

I have a user control that has dynamic controls loaded to it in
Page_Init.
this works well. I have a function inside the user control:
GetValues()
When i add this usercontrol to a page: test.aspx and i call
GetValues(), it returns me the values of the dynamically added controls
correctly.

I created a user control that, had a datalist with checkboxes inside of the
item template. These checkboxes would not retain state. For instance, if I
set them to checked inside of the load event of the UserControl, they would
appear false(the default value) when inside the top level datagrid.
Here's the walkthrough (tried to make it as quick as possible):

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
