c# - __doPostBack is not defined

Question

Im getting that error when try to call a __doPostBack on one of my pages, every page that i have in the project use __doPostBack function but in this particular page im getting that Javascript error.

i was looking in the internet and the only thing i read is that this error happends when i have a unclose tag but i review the site and its ok.

Error: __doPostBack is not defined Source File: htt://localhost:99/ProjectName/Disable.aspx Line: 1

Answer 1

The run time/client side error __doPostBack is undefined hassled me for a few hours. There was lots of misleading/incorrect help on the net. I inserted the following line of code in the Page_Load event of the default.aspx.cs file and everything worked fine, on my system and in production with GoDaddy.

ClientScript.GetPostBackEventReference(this, string.Empty);
