What do you mean by "Gridview"? Which one? Exact fully-qualified type name, please. What's the problem. http://www.whathaveyoutried.com so far?

I mean winforms Gridview control

Then use System.Windows.Forms.DataGridView. Don't waste time on old lousy staff left in FCL only for backup compatibility with already written code. And what's the problem? If you can use a grid view in any way at all, you should be able to get and set cell values...

Please see my comments to the question. All you need is this:
http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.value.aspx[^],
http://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.valuetype.aspx[^].

What is "click on the instant"? Anyway, no matter what you want to click on, I hope you know how to handle event. But do you know how to read MSDN? It's well documented and well to easy to find out such things.

I would not advise "no button", but what else could be a problem? If it is difficult, you should lean on somewhat simpler projects. Can you create classes, create and handle events? Properties, generics? Virtual, overriding, interfaces, polymorphism? Before getting to UI, you should better learn it all on simple projects, probably console-only... Otherwise, what's would be the answer except writing the full code for you?.. :-)
