n this Example you can learn how to get the values of selected row from a Gridview and display the values in textboxes using C# code.
Design:
Add Gridview in .aspx page and bind a Data using SqlDataSource or msaccess.and Add Four Textboxes to display a data in Textboxes when the GridviewRow is Selected.
Set the Gridview AutoGenerateColumns property to 'False'.
You will need to set the Bound column in order to see the text in the cells of the grid view control.
