Hi Naim -

Bind your GridView Items in DataBound Event and Add try catch (For Specific Exception type) there to Catch the error and show user friendly message to user.

Thanks & Regards

The thrown exception can be caught or dealt within the calling method using the try...catch block.
The code that may throw an exception which we want to handle is put in the try block. This is called an attempt to catch an exception.
The code to handle the thrown exception is placed in the catch block just after the try block. This is called catching the exception. We can define which particular class of exception we want to deal in this catch block by mentioning the name of exception after the catch keyword
Multiple catch blocks can be defined for a single try block where each catch block will catch a particular class of exception.
The code that must always be executed after the try or try...catch block is placed in the finally block, placed just after the try or try...catch blocks. This code is guaranteed to always be executed whether the exception occurs or not.
When an exception is raised during the execution of the code inside the try block, the remaining code in the try block is neglected and the control of execution is transferred to the respective catch or finally block.
