Hi Team,
AsynPostBack Trigger is not working in .NET 4.5.2 (VS2015).Also, i tried with .NET 4.6.1 and 4.6.2 still issue persist.But,same code is working fine in VS2010(.NET 4.0).
Ajax control tool kit version is 16.1.0.0.
Since we are upgrading .NET 4.0 to 4.5.2 using VS2015 and it's a show stopper issue. Please give a workaround/fix.
Steps to reproduce the below issue.
Issue:
0x800a139e - JavaScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near 'hello1|#||4|240|upda'.
