As you have found out controls that are added to the DOM on the client do not get saved in ViewState and reconstituted in the code behind. ViewState is encrypted and validated to prevent tampering so there is no way to have the dynamic controls added.

A common method is to use JavaScript and Ajax to send the values of the controls to the server. This can be done using a web service or using PageMethods with ASP.NET.

Is there any postback happening when you close the modal form. If yes! then you need to recreate the dynamic controls again! I also faced similar issue sometime back and this was the solution.
Hope this helps!

Turnoff the viewstate is it is of no use, means if you are not retaining the state on postback. Use ajax and bind the control on every postback. So the screen will not flicker, as well as get the output as you want.

Avoid the use of updatepanel, use pagemethod or webservice to do so.

it is just an idea..... may be it helps
