c# - What could be causing different behaviour remotely on asp.net site -

-

i have site have developed in asp.net. on debugging site hosted using iis7 noticed bug, cannot reproduce when run locally in vs, meaning can't see error. bug occurs on check box changed event of devexpress check box. connects database using devart.postgres sql component , linq. however, same connection anywhere else in project. same code works elsewhere in project. error is:

the requested name valid, no data of requested type found.

part of code in if statement checks if textbox blank if not run code within if statement, interestingly enough if text box blank code runs, must in if statement? commented out of code , tried again , still not run. beginning lost objectivity problem, hope can help.

the error have posted suggests there problem resolving address. example, when check checkbox, in code tries resolve valid address, dns server doesn't recognise it. doing involve name resolution?

can share code causes error?
