asp.net无法更新数据库！

public partial class EgNewsEdit : System.Web.UI.Page
{
NewsBusiness nb = new NewsBusiness();
NewsEntity ne = new NewsEntity();
protected void Page_Load(object sender, EventArgs e)
{
Label2.Text = Convert.ToString(Session["newsid"]);
DataSet ds = nb.GetNewsInfoByID(Label2.Text);
TextBox1.Text = ds.Tables[0].Rows[0][1].ToString();
TextBox2.Text = ds.Tables[0].Rows[0][2].ToString();
TextBox3.Text = ds.Tables[0].Rows[0][3].ToString();
TextBox4.Text = ds.Tables[0].Rows[0][4].ToString();
FreeTextBox1.Text = ds.Tables[0].Rows[0][5].ToString();
Label1.Text = ds.Tables[0].Rows[0][6].ToString();
DropDownList1.Text = ds.Tables[0].Rows[0][7].ToString();
DropDownList2.Text = ds.Tables[0].Rows[0][8].ToString();
ImageButton1.ImageUrl = ds.Tables[0].Rows[0][9].ToString();
DropDownList3.Text = ds.Tables[0].Rows[0][10].ToString();
}
protected void Button1_Click(object sender, EventArgs e)
{
ne.ID = Convert.ToInt32(Label2.Text);
ne.Name = TextBox1.Text;
ne.Writer = TextBox2.Text;
ne.Source = TextBox3.Text;
ne.Editor = TextBox4.Text;
ne.Content = FreeTextBox1.Text;
ne.Time = Label1.Text;
ne.Range = DropDownList1.Text;
ne.Classify = DropDownList2.Text;
ne.Image = ImageButton1.ImageUrl;
ne.Hot = DropDownList3.Text;
int count = nb.UpdateNews(ne);
if (count >= 0)
{
Response.Redirect("EgNewsList.aspx");
}
}
}
就是先从其他网页获取数据，点击Button1再更新到数据库，但Button1_Click无法将数据更新到数据库，求高手指点啊！谢谢了~
[解决办法]
检查int count = nb.UpdateNews(ne);中UpdateNews方法的实现。
[解决办法]
少打了一句 在 UpdateNews里 看看有木有异常
