當我的頁面加載時,將查詢一些值的數據庫,並填充一些文本框與他們:爲什麼我提交時我的文本框無法識別值已更改?
protected void Page_Load(object sender, EventArgs e)
{
tadbDataContext tadb = new tadbDataContext();
Dictionary<string, string> hexColors = tadb.msp_silentAuctionColors.ToDictionary(t => t.colorDescription, t => t.colorValue);
tbTextColor.Text = hexColors["textColor"];
tbAltColor.Text = hexColors["altColor"];
tbBackgroundColor.Text = hexColors["backgroundColor"];
}
我然後更改值,並嘗試重新提交到數據庫中,通過點擊一個按鈕,執行以下操作:
using (tadbDataContext tadb = new tadbDataContext())
{
var textColor = tadb.msp_silentAuctionColors.Single(x => x.colorDescription == "textColor");
var altColor = tadb.msp_silentAuctionColors.Single(x => x.colorDescription == "altColor");
var backgroundColor = tadb.msp_silentAuctionColors.Single(x => x.colorDescription == "backgroundColor");
textColor.colorValue = tbTextColor.Text;
altColor.colorValue = tbAltColor.Text;
backgroundColor.colorValue = tbBackgroundColor.Text;
tadb.SubmitChanges();
}
回傳的值是原始值(而非更改的值)。如果我註釋出裝入文本框的行,它可以正常工作。
