You can access the data of gridview by using for loop, please see below code:
Suppose your Gridview is "gv"

for (int i = 0; i < gv.Rows.Count; i++)
{
TextBox txt = (TextBox)gv.Rows[i].FindControl("txtorder");
int id = Convert.ToInt32(gv.DataKeys[_count].Value);
// You can get gridview data and pass it into another table by firing insert query here.
}
