On an ASP LinkButton onclick event I try to open anoter tab and show a response from an external web page. The LinkButton is within an UpdatePanel, not to reload the entire page on click. This works good for Mozila Firefox and Google Chrome, but on Internet Explorer (any version including Edge) it is not working showing the following message:
Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.
I have tried to update the .Net target platform as in this msdn blog post alternative solution (since I was not able to perform the first solution, because I think it's about other IIS version and the options are not as in the discribed steps) and after the .Net target version has been changed from 4.0 to 4.5, the UpdatePanel was not recognized anymore.
Also in all the msdn examples UpdatePanel was only on .Net 4.0 maximum, so it it supported in .Net 4.5 and I make some mistake, or changing .Net version is not a solution in this case?
