Hi All,
In our SP 2013 custom developement, we have an application page (aspx) to submit a registration details. Here we have option to add multiple entries at same time (dynamic table). so on page load we get all required datas from site and keep that in DataTable then saved that in ViewState. In our application we have nearly 3000 items in one of our master list, so get all 3000 items and save that in ViewState. we are using UpdatePanel in the application page.
In this case occasionaly i get ViewState is Null error on few postback. sometime this works fine. I am not able to figure out exact scenario.
Note: Same logic working in SP 2010 environment.
I have few questions from my side
1. Is there any different between SP 2010 & SP 2013 in the form of handling ViewState data?
2. Is there any limitation with ViewState size?
3. Is UpdatePanel cause any issues?
Pls let me know if any one of you face this kind of issue in SP 2013.
