collapsible gridview cell ASP.net

I am working on Gridview in ASP.NET(C#) and have c开发者_如何学Pythonells that need to have as follwing example,

+ View

And, once user click on the "+View", I want to display the info on the same cell.

- Name:Tom Age: 16 

And,, it will go back "+View" when user clicks on the cell So, basically what i need is collapsible gridview, I am looking for a way to do this without Ajax.

Thanks.

A lot of examples use AJAX for this, but there are some examples without it. Like this one, and this one. They have a little javascript in them, but not AJAX.
