Lets say we created some dynamic controls at runtime (such as textboxes, radio buttons etc,).

When we perform a postback (or partial postback) we want to be able to access those controls (or at least the values the user put into them).

We know that the data is in the viewstate, but ASP.NET doesn’t really know which control a ViewState item belongs to. It only knows to match a viewstate item and a control through the same index (e.g. Matches item n in the viewstate tree to item n in the control tree). Therefore in order to get the dynamic controls' data, we need to re-create the controls each time the page is postbacked.

BUT in order for this to work, we need to re-create the controls in the Page_Init function NOT in the Page_Load.

Why? Because when the ViewState is created it needs all the controls to already exist.

This figure (taken from MSDN) shows the events in the Page Life Cycle, as we can see, the viewstate is loaded AFTER the init but before the page load.

In conclusion - Call the function that creates the dynamic controls in the page_init and you should be able to see all the values the user entered when the page postbacks

 

Updated:

BUT WAIT there is another way: If the controls all had unique Ids and you're not interested in re-creating them again every postback - you could always look for them in the Request Object.

The Request.Form is a NameValueCollection that holds the values of all the controls that were part of the form, just search it for whatever you're looking for
