当我的页面加载时,将查询一些值的数据库,并填充一些文本框与他们:为什么我提交时我的文本框无法识别值已更改?
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"];
}
我然后更改值,并尝试重新提交到数据库中,通过点击一个按钮,执行以下操作:
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();
}
回传的值是原始值(而非更改的值)。如果我注释出装入文本框的行,它可以正常工作。
