I'm developing an ASP.NET Webform website using .NET Framework 4.6, C# and Javascript,

I've used HiddenField to store a value from a navigation drawer, then do a postback to update value in UpdatePanel, but seem that the code stucked at __doPostBack() on iOS, iPadOS browsers (all Safari, Chrome, Firefox), for Windows browsers everything works fine. Below is my Javascript code:

function headChange(e) {
   __doPostBack('<%=HiddenField1.ClientID%>', '');
};

I tried several methods found on Internet such as:

  • Added <browserCaps userAgentCacheKeyLength="256"/> in web.config
  • Added return false; after __doPostBack('<%=HiddenField1.ClientID%>', '');
  • Replace __doPostBack('<%=HiddenField1.ClientID%>', ''); by <%= Page.ClientScript.GetPostBackEventReference(HiddenField1, String.Empty) %>;
  • Added a browser file to App_Browsers folder

but all with no luck,

Has anyone encountered the same problem and found the solution for this? Thank you very much!

"Function.caller used to retrieve strict caller" cause by __doPostBack function in MicrosoftAjaxWebforms.js

Then I found the solution for this by https://stackoverflow.com/a/25686598/7819116
