<pre lang="cs">protected void GridView2_RowDataBound(object sender, GridViewRowEventArgs e)
    {

C#

if (e.Row.RowType == DataControlRowType.Footer)
           {

   Testbox t1= (Testbox )e.Row.FindControl("id of the textbox1");
   Testbox t2= (Testbox )e.Row.FindControl("id of the textbox2");
   Testbox t3= (Testbox )e.Row.FindControl("id of the textbox3");
   Testbox t4= (Testbox )e.Row.FindControl("id of the textbox4");
  float total=float.parse(t1.text+t2.text+t3.text);
   t4.Text = total.tostring();
           }

if you have any button click event do this at event

command name="calculate"

C#

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
  {

if (e.CommandName == "calculate")
{

ImageButton img = (ImageButton)e.CommandSource as ImageButton;
GridViewRow grid = img.NamingContainer as GridViewRow;

Testbox t1= (Testbox )e.Row.FindControl("id of the textbox1");
Testbox t2= (Testbox )e.Row.FindControl("id of the textbox2");
Testbox t3= (Testbox )e.Row.FindControl("id of the textbox3");
Testbox t4= (Testbox )e.Row.FindControl("id of the textbox4");

C#

float total=float.parse(t1.text+t2.text+t3.text);
            t4.Text = total.tostring();

}
}
