You should first add a test for that button existing. You should also use button identifiers rather than indices in case your code gets called multiple times. Are you really sure that you want this removed rather than disabled?

Yah your suggestion is good ,but I am sure code is inserted at a place and unless
click event is raised it is not getting called,this is something very strange,I am running application and finding that button is not there

It's impossible to suggest anything more since we do not know what is going on in your program. Unfortunately the only way to make progress with issues like this is to spend time with the debugger.

Perhaps what you say Is Right,but I feel Visual Studio 2010 is not so stable version

No, I'm pretty sure you are doing something wrong, but, as I said, without a lot more information it's impossible to guess what.
