Its an urgent requirement. asp.net vb.net web-services asp.net-ajax share|improve this question asked Jan 6 '12 at 11:26 JayOnDotNet 337516 A 500 normally just means that there was an exception in the server side code, which wasn't handled. You'll need to trace/log through the webservice to see what is failing. –Jon Egerton Jan 6 '12 at 11:29 add a comment| 4 Answers 4 active oldest votes up vote 2 down vote accepted A 500 normally just means that there was an exception in the server side code, which wasn't handled. You'll need to trace/log through the webservice to see what is failing. You're almost certainly looking for a .Net code error. share|improve this answer answered Jan 6 '12 at 11:34 Jon Egerton 22.8k85191 add a comment| up vote 3 down vote 500 errors are internal server errors. The web service most likely had an unhandled exception thrown somewhere, causing IIS to return this error. You need to look in your event logs to see what the actual exception was. These are exceptions thrown by ASP.NET and can be any sort of exception. share|improve this answer edited Jan 6 '12 at 11:33 answered Jan 6 '12 at 11:28 Oded♦ 342k54595787 hey I could not find any logs in eventmanager regarding this 500 exception. Is there any specific name to this exception –JayOnDotNet Jan 6 '12 at 11:32 @JayaPrakashRokkam - You need to look for any exception that ASP.NET threw. –Oded♦ Jan 6 '12 at 11:32 Its working now. I didnt do anything.. –JayOnDotNet Jan 6 '12 at 11:51 add a comment| up vote 1 down vote Are you using a database query for your cascadingdropdown? If you are then check the results of your SQL statement. Most likely your query returns or has a null value in it. share|improve this answer edited Mar 2 '12 at 6:27 answered Mar 2 '12 at 6:21 Darwin 112 add a comment| up vote 0 down vote You may find this helpful:
