All the connection are coded inthe file manually.

The connection string should not be hardcoded. It should be stored in a configuration file in one centralised place so that are not obliged to recompile your application every time you need to modify the connection string.





In your case the problem is obviously in you connection string. The error generated is quite self explaining.





In general, runtime errors cannot be avoided but rather handled. You should place code that is susceptible to throw exceptions in try - catch blocks. Code within the try scope is referred to as protected code.

Reply:Make sure the connection string defined for the connection object is valid. Check the name of the website or its IP in the connection string and try it in a WebForm and see if it works. If yes, then use it in your web application. Good luck.

Check the Web.Config file for your connection string..
