导出excel问题

[Z_Lacey]

导出excel，数据全是代码。 我检查过了，里面的代码跟源文件（页面右击-->查看源文件）的代码一模一样。
请问有谁知道这个问题怎么解决?

protected void Button1_Click(object sender, EventArgs e)
{
if (this.GridView3.Rows.Count == 0)
{
Response.Write("<script>alert('没有查找到数据,无法导出！')</script>");
}
else
{
//this.GridView3.AllowPaging = false; // 将有分页的GridView中的数据全部导出到Excel
//GridView3Bind();
export("application/ms-excel", "工作人员.xls");
// 换成 export("application/ms-word", "工作人员.doc"); 那么导出的就是Word格式的了.
//this.GridView3.AllowPaging = true;
//GridView3Bind();
}
}
public void export(string FileType, string FileName)
{
string style = "<style>td{mso-number-format:\"\\@\";}</style>";//导入到excel时,保存表里数字列中前面存在的 0 .
for (int i = 0; i < GridView3.Columns.Count; i++)
{
if (GridView3.Columns[i].GetType() == typeof(CommandField))
GridView3.Columns[i].Visible = false;
}
PrepareGridViewForExport(GridView3);
Response.Clear();
Response.Charset = "GB2312";
Response.ContentEncoding = Encoding.UTF7;
Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(FileName, Encoding.UTF8).ToString());
Response.ContentType = FileType;
this.EnableViewState = false;
this.GridView3.AllowPaging = false;
System.Globalization.CultureInfo myCItrad = new System.Globalization.CultureInfo("ZH-CN", true);
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
this.GridView3.RenderControl(htw);
Response.Write(style);
Response.Write(sw.ToString());
Response.End();
}
public override void VerifyRenderingInServerForm(Control control)
{
//在后台中重载VerifyRenderingInServerForm()方法，否则报错为“类型"GridView"的控件"GridView1"必须放在具有 runat=server 的窗体标记内“
}
private void PrepareGridViewForExport(Control gv)//模式化特殊元素 flashcong
{
Literal l = new Literal();
for (int i = 0; i < gv.Controls.Count; i++)
{
if (gv.Controls[i].GetType() == typeof(HyperLink))
{
l.Text = (gv.Controls[i] as HyperLink).Text;
gv.Controls.Remove(gv.Controls[i]);
gv.Controls.AddAt(i, l);
}
if (gv.Controls[i].GetType() == typeof(LinkButton))
{
l.Text = (gv.Controls[i] as LinkButton).Text;
gv.Controls.Remove(gv.Controls[i]);
gv.Controls.AddAt(i, l);
}
else if (gv.Controls[i].GetType() == typeof(DropDownList))
{
l.Text = (gv.Controls[i] as DropDownList).SelectedItem.Text;
gv.Controls.Remove(gv.Controls[i]);
gv.Controls.AddAt(i, l);
}
else if (gv.Controls[i].GetType() == typeof(CheckBox))
{
l.Text = (gv.Controls[i] as CheckBox).Checked ? "True" : "False";
gv.Controls.Remove(gv.Controls[i]);
gv.Controls.AddAt(i, l);
}
if (gv.Controls[i].HasControls())
{
PrepareGridViewForExport(gv.Controls[i]);
}
}
}
这方法能用 我昨天还用的
