Fix PC Errors in Minutes
Recently, some of our users reported that they encountered the Ajax 500 cascading dropdown error.
I have a better C # cascading dropdown that works fine in debug mode locally and in debug mode from live server, but I get [Method 500] errors in both cases when viewing the table in real time from the browser. If I click on the first dropdown, [Method error 500] shrinks, which then populates the second largest dropdown [Method with error 500].
[ScriptService]public class WasteDropDown: System.Web.Services.WebService [WebMethod] public CascadingDropDownNameValue  GetBinType (known for CategoryValues, franchise category) [WebMethod] public CascadingDropDownNameValue  GetWaste (known string CategoryValues, string category) SqlConnection conn = charge SqlConnection (myConn.conn); Connecticut Open (); SqlCommand comm; comm = new SqlCommand ("dbo.sl_binQWT", conn); comm.CommandType = CommandType.StoredProcedure; SqlDataReader dr = comm.ExecuteReader (); List
d = new List (); to (Doctor Reading ()) l.Add (new CascadingDropDownNameValue ( dr ["binWT"]. To string (), dr ["wtID"]. To string ())); Connect.Close (); Return l.ToArray ();
There are no ASP.Net errors in the logs. However, I also ran a similar CD on an old server on another website, it works great – very annoying.
I’ve looked at each of these questions on Stackoverflow, but to be honest, I’m not quite sure what the solution was – although I don’t seem to have any similar DLLs in my bin folder. I really think the problem is here somewhere.
I have undoubtedly doubled the number of SQL queries checked and they return almost all the data. Install
I started looking for failed requests and got really chorusBest result:

The code works fine on this other website on the same webserver. I took out Fiddler, which resulted in the following error:
