ASP.NET error checking

Question

When working with C# asp.net 2010 web controls, I am wondering if there is a method for handling errors? Basically is there any special way of handling errros that can occur? If not, when a web control is being accessed, should I put the code within a try-catch block?

As a general rule of thumb you should put all your code in Try..Catch block. I tell you the advantage of this approach. When you are developing the application you will always run/test it in a such way that it does not crash It is a natural human tendency. But when the same code is deployed on Client Site he will run it in the worst case he can. In order to avoid your module crashing it is advisable that you put your code in Try..Catch Block. For user control as well this rule remains the same. But in the catch block you can log this error. You can log the error in Eventviewer Text File etc. so that at a later time you can have a look at the situation which lead to this error. You can use Microsoft Logging Application Block NLog etc frameworks for logging purpose. Hope this helps. All the best.

ASP.NET itself has very handy error handling mechanism. You just need to read them and u done. Using try-catch is also a mechanism to display the appropriate error messages. Errors in ASP.NET can be handled by page level and application level. More ways:- (i) Placing break-points on desired code-line and watch its output (ii) Using Text Visualizer (iii) Using customErrors handler in configuration files Please go through following urls for more help http://www.worldofasp.net/tut/ErrorHandling/Error_Handling_techniques_in_ASPNET_20_82.aspx http://dotnetguts.blogspot.com/2007/10/error-handling-in-net-with-example.html http://www.c-sharpcorner.com/UploadFile/akukreja/CustomErrorHandlingASPNET11142005235614PM/CustomErrorHandlingASPNET.aspx
