'Obout.Grid.GridTemplate'タイプのオブジェクトをキャストして 'System.Web.UI.WebControls.GridViewRow'と入力できません。解決しない

Question

disable gridviewグリッドビューの中にあるボタンをクリックします。それで、私は以下のコードを書いています。

protected void btnPayGenInvoice_Click(object sender, EventArgs e) 
{ 
    if (strMode == "M") 
    { 
     Button btn = (Button)sender; 
     GridViewRow row = (GridViewRow)btn.Parent.Parent; 
     row.Enabled = false; 
    } 
} 

しかし、私は

型のオブジェクトをキャストすることができませんなどのエラーを取得しています 'Obout.Grid.GridTemplate' 'System.Web.UI.WebControls.GridViewRow' を入力します。

は親切に私はライン GridViewRow row = (GridViewRow)btn.Parent.Parent;

UPDATE

取得エラーここで間違っているものを知ってみましょう。

protected void GetRowDataPay(object sender, CommandEventArgs e) 
{ 
    int rowIndex = int.Parse(e.CommandArgument.ToString()); 

    Hashtable dataItemPay = GridPayInfo.Rows[rowIndex].ToHashtable() as Hashtable; 

    if (ObjPriCon.State != ConnectionState.Open) 
    { 
     ObjPriCon.Open(); 
     OracleCommand cmdMkeyPay = new OracleCommand("select XXCUS.XXACL_LAND_PURC_INV_VIEW_MKEY.nextval from dual", ObjPriCon); 
     string MkeyPay = Convert.ToString(cmdMkeyPay.ExecuteOracleScalar());
