I have a couple of CascadingDropDown controls on an ASP.NET page and am filling them from a code behind function that makes a call to a SQL Server 2005 database. My problem is that sometimes I receive a 'Method error 500' when filling the second dropdownlist based on a parent control. I am concatenating three fields together and I can mix and match 2 of them, but when I use all three, I consistently get the error.
Example "Select StoreCode + ' ' + City + ' ' State as Name From Table".
Is there a data size limit with using this control?
Also, I am able to bind the same data to a dropdownlist not used in AJAX.
Thanks in Advanced,
Marc
