ASP.NET 500 Internal Server Error while calling webmethod from javascript

Question

I\'m trying to call the webmethod fucntionality using AJAX but unable to get the appropriate results. I have googled my problem and found many solution but thos

Answer 1

First, it the webmethod is in the page class, and not in a Webservice class, then it should be static.

Second, the data transfered is not really a string, but an object, so change it to:

var dataString = { 'value':  value  };

Third thing, "type" is for older versions of jquery, you should either change your ajax call to:

method: "GET",
url: pagePath,
data: dataString,
contentType: "application/json; charset=utf-8",
dataType: "json",...

Or change the function in the server side to get post calls, by removing the

UseHttpGet = true
