图一是我自己做的界面，图二是运行的结果，以前运行都没问题，但是今天运行的时候，图二变成了这样，什么都不显示了，全大神指点指点为什么会出现这样的情况？要怎么解决，因为要答辩了，所以 有点捉急
代码以下：
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Data.SqlClient;
public partial class Admin_DD : System.Web.UI.Page
{
SqlHelper insert = new SqlHelper();
SqlHelper data = new SqlHelper();
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
Binderbumen();
Label1.Text = Request.QueryString["bumen"].ToString();
DropDownList1.DataSource = data.GetDataReader("select * from Job ");
DropDownList1.DataTextField = "jobname";
DropDownList1.DataValueField = "JobId";
DropDownList1.DataBind();
}
}
/// <summary>
/// 绑定部门
/// </summary>
private void Binderbumen()
{
DropDownList2.DataSource = data.GetDataReader("select * from BuMen ");
DropDownList2.DataTextField = "BuMenName";
DropDownList2.DataValueField = "BuMenId";
DropDownList2.DataBind();
}
protected void Button1_Click(object sender, EventArgs e)
{
if (Request.QueryString["bumen"].ToString() == DropDownList2.SelectedItem.Text)
{
Alert.AlertAndRedirect("部门相同不能调动！", "DiaoDongManger.aspx");
}
else
{
data.RunSql("insert into DiaoDong(UserId,YBumen,DDBumen,ZhiWei,ZhuangTai)values('" + Request.QueryString["Userid"].ToString() + "','" + Request.QueryString["bumen"].ToString() + "','"+DropDownList2.SelectedItem.Text+"','"+DropDownList1.SelectedItem.Text+"','"+DropDownList3.SelectedItem.Text+"')");
data.RunSql("update UserInfo set bumen='" + DropDownList2.SelectedItem.Text + "' ,job='" + DropDownList1.SelectedItem.Text + "',ZhuangTai='"+DropDownList3.SelectedValue+"' where Userid=" + Request.QueryString["Userid"].ToString());
Alert.AlertAndRedirect("添加成功", "DiaoDongManger.aspx");
}
}
}
