日期只顯示在1個文本框中

-1

當我從日曆中選擇日期時，其他文本框中的日期消失。我不知道是什麼原因導致這個問題，它第一次，我看到這樣的問題。我試圖刪除壓光機，但我沒有成功解決問題。謝謝。日期只顯示在1個文本框中

您在每次回傳結合數據，你應該檢查IsPostBack屬性來避免這種情況，只有在第一時間將數據綁定頁面加載： -

protected void Page_Load(object sender, EventArgs e) 
{ 
    if(!IsPostBack) 
      BindData(); 
}

謝謝它的作品。但現在我得到這個錯誤，當我按下添加。「{」字段列表中的「未知列'承諾'」}「。謝謝！ –

@ DR.P - 爲此您需要檢查您的數據庫，如果該列真的存在於表中。此外，您應該創建一個SP，而不是編寫如此大的內聯查詢。 –

exscuse我但什麼是SP？ –
