I have a gridview that returns several records for the same user and each record has a column with a check box. I need to allow the user to choose only one to check. Also one check box is always supposed to be checked. What is the best way to do it? I was thinking of writing a stored procedure that checks if only one is checked, and then returns true or false. I think there is a more efficient way to do it...

I have a web form with a gridview control on it. The GridView has a column of check boxes. Before the web form closes I need to check if more than one check box was checked. If more than one check box was checked, then I need to display a popup message box informing the user that only one check box should be checked? I need to check to see if more than one check box was checked, when a "Submit" button on the form is pressed.
How can this be done using Asp.net/C# and Java Script? I know how to iterate through rows of a Grid control so I can do that in the C# code. But how to keep the web form open before I iterate through the rows, I don't know?
I need to validate textbox is not empty if check box is checked.
