Gridview Edit With Double Click

1)Don't say "it's urgent!" - it isn't! It may be to you, but not to us, and all it does is annoy people. It basically says "I have left this too late because I was lazy, now you fix it for me" which doesn't help you at all.
2) Don't say "Give me the code" - people will also assume that you have done nothing to help yourself, which will also not help you to get a usful response. Instead, edit your question to show what you have done to try and solve the problem, and where you are having problems. People will be a lot more helpful then.
