Use the .Visible property of the control you want to hide or show.

When you click the button, make the text box

MyTextBox.Visib le = true;

I first have to search which checkbox(line) was selected then the textbox must appear on that line within the griedview.

I think i have to use the FindControl method, but im not sure how.
