The error message is clear and you are even given the line the error occurs on so what sort of help do you need?

Hi,

As the exception message itself gives the detailed information, it is very easy to fix , if it is your code.

The exception is throwing from the Select_CheckedChanged1 event. How many rows / columns are there in that grid view? Please check for null. That will solve your issue.

Regards
Sebastian
