on your gridview templates, look at the EditRowTemplate, you will see that it contains all the editable controls (most likely textboxes) delete the textboxes and add Labels instead and bind them to your datasource. That way the data is still displayed but wont be editable (except for the control that you want to be edited)

Try it and let me know if you need more help.
