GridViewテキストフィールドのデータの発行

Question

グリッドビューにテキストフィールドの値が表示されません。行だけが増加しますが、テキストは取得されません。

これは私がこの目的のために持っているコードです。

DataTable dt1 = new DataTable(); 
    bool flag = false; 
    protected void Page_Load(object sender, EventArgs e) 
    { 
     if (!IsPostBack) 
     { 
      gridVIEWData(); 
      Gridview1.DataSource = dt1; 
      Gridview1.DataBind(); 
     } 
    } 
    protected void gobtn_Click(object sender, EventArgs e) 
    { 

     if (Session["dtInSession"] != null) 
     dt1 = (DataTable)Session["dtInSession"]; 


     DataRow dr = dt1.NewRow(); 
     dr["Product"] = DropDownList1.SelectedItem; 
     dr["Size"] = DropDownList2.SelectedItem; 
     dr["Case"] = casetxt.Text; 
     dr["Weight"] = TextBox1.Text; 
     dr["Price"] = TextBox2.Text; 
     dt1.Rows.Add(dr); 

     Session["dtInSession"] = dt1;  
     Gridview1.DataSource = dt1; 
     Gridview1.DataBind(); 
    } 

    private void gridVIEWData() 
    { 
     dt1.Columns.Add("Product", typeof(string)); 
     dt1.Columns.Add("Size", typeof(string)); 
     dt1.Columns.Add("Case", typeof(string)); 
     dt1.Columns.Add("Weight", typeof(string)); 
     dt1.Columns.Add("Price", typeof(string)); 
     Session["dtInSession"] = dt1; 
    } 

いずれかが私に

**I hope you looking for something like this** 

protected void BindGridview1() 
{ 
    DataTable dtt = new DataTable(); 
    DataTable dt = (DataTable)Session["od"]; 
    dtt.Columns.Add("BookingNO", typeof(string)); 
    dtt.Columns.Add("ItemName", typeof(string)); 
    dtt.Columns.Add("Size", typeof(string)); 
    dtt.Columns.Add("Unit", typeof(string)); 
    dtt.Columns.Add("Price", typeof(string)); 
    dtt.Columns.Add("PendingQty", typeof(string)); 

    for (int i = 0; i < dtt.Rows.Count; i++) 
    { 
     DataRow dr = dtt.NewRow(); 
     dr["BookingNO"] = string.Empty; 
     dr["ItemName"] = string.Empty; 
     dr["Size"] = string.Empty; 
     dr["Unit"] = string.Empty; 
     dr["Price"] = string.Empty; 
     dr["PendingQty"] = string.Empty; 
     dtt.Rows.Add(dr); 
    } 
    dtt = dt; 
    gvDetails.DataSource = dtt; 
    gvDetails.DataBind(); 


    for (int i = 0; i <= dt.Rows.Count - 1; i++) 
    { 
     TextBox BookingNO = (TextBox)gvDetails.Rows[i].FindControl("BookingNO"); 
     TextBox ItemName = (TextBox)gvDetails.Rows[i].FindControl("ItemName"); 
     TextBox Size = (TextBox)gvDetails.Rows[i].FindControl("Size"); 
     TextBox Unit = (TextBox)gvDetails.Rows[i].FindControl("Unit"); 
     TextBox Price = (TextBox)gvDetails.Rows[i].FindControl("Price"); 
     //TextBox DueDate = (TextBox)gvDetails.Rows[i].FindControl("DueDate"); 
     TextBox PendingQty = (TextBox)gvDetails.Rows[i].FindControl("PendingQty"); 
     BookingNO.Text = Session["BookingNO1"].ToString(); 
     ItemName.Text = dt.Rows[i]["ItemName"].ToString(); 
     Size.Text = dt.Rows[i]["Size"].ToString(); 
     Unit.Text = dt.Rows[i]["Unit"].ToString(); 
     Price.Text = dt.Rows[i]["Price"].ToString(); 
     //DueDate.Text = dt.Rows[i]["DueDate"].ToString(); 
     PendingQty.Text = dt.Rows[i]["PendingQty"].ToString(); 

    } 

}
