how to prevent my button from being clicked if no data is selected?

[xinnie]

I have this "View" button as I click on the data in my datagridview, it'll show some reports. How do I prevent my "view" button from being clicked if no data is selected? Like locking it, it's commonly used, don't know how to express better hope my description is clear.

You could handle the Data-selection-event, that if no data was selected, you set the button's Enabled=False or something like that.
