Asp GridView가 업데이트되지 않습니다.

Question

중첩 된 GridView을 사용하고 있습니다. 편집을 클릭하면 아이템이 텍스트 상자에 편집을 위해 나타나지만 새 값은 행 업데이트에 반영되지 않습니다. 나는 브라우저를 통해 그것을 검사 해 보았고, 심지어는 오래된 값을 가져왔다. 새 수량 값을 구 수량 값을 보여주는 브라우저의 요소 검사 500

      string unit = Session["unit"].ToString(); 
      string proj = Session["project"].ToString();

He 이 코드를 사용해 행을 업데이트 할 수 있습니다.

protected void GVInvoiceDet_RowUpdating(object sender, GridViewRowEventArgs e) 
{ 
    string itemCode= (TextBox)GVInvoiceDet.Rows[e.RowIndex].FindControl("txtItemCode")).Text; 
    string quantity = (TextBox)GVInvoiceDet.Rows[e.RowIndex].FindControl("txtItemQty")).Text; 
    string unitRate = ((TextBox)GVInvoiceDet.Rows[e.RowIndex].FindControl("txtItemUnitRate")).Text; 
    string unitValue = ((TextBox)GVInvoiceDet.Rows[e.RowIndex].FindControl("txtItemUnitValue")).Text;  
    string unit = Session["unit"].ToString(); 
    string proj = Session["project"].ToString(); 
    GVInvoiceDet.EditIndex = -1; 
    // call bind grid method here 
}
