TextBox newname=(TextBox)GridView1.FooterRow.FindControl("txtnewUserName");
string name=newname.Text;//This is Enough If U want string; If you want to convert it into int
int i=Convert.ToInt16(newname.Text);

If you dont enter anything in textbox then it will show null. If you enter something like sa in texbox then the value stored in name is sa. Check wheather you enterd in textbox
