我的后台代码:
protected void Button1_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.Charset = "utf-8";
Response.AppendHeader("Content-Disposition", "attachment;filename=ASMCRPT.xls");
Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
Response.ContentType = "application/ms-excel";
//this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.GridView1.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();
我点击Button.然后它指着
this.GridView1.RenderControl(oHtmlTextWriter);
说:
类型“GridView”的控件“GridView1”必须放在具有 runat=server 的窗体标记内。
protected void Button1_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.Charset = "utf-8";
Response.AppendHeader("Content-Disposition", "attachment;filename=ASMCRPT.xls");
Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
Response.ContentType = "application/ms-excel";
//this.EnableViewState = false;
System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);
this.GridView1.RenderControl(oHtmlTextWriter);
Response.Write(oStringWriter.ToString());
Response.End();
我点击Button.然后它指着
this.GridView1.RenderControl(oHtmlTextWriter);

你的代码没问题。
只要添加这一个空方法就可以了。 这个你可以看下MSDN.
public override void VerifyRenderingInServerForm(Control control)
{
}
看我以前做的。
按钮事件：
protected void Button1_Click(object sender, EventArgs e)
{
Response.ClearContent();
Response.AddHeader("content-disposition", "attachment; filename=MyExcelFile.xls");
Response.ContentType = "application/excel";
StringWriter sw = new StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
gvUsers.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
}
绑定数据。
private void BindData()
{
SqlConnection myConnection = new SqlConnection("Server=localhost;Database=School;Trusted_Connection=true");
SqlDataAdapter ad = new SqlDataAdapter("SELECT * FROM Users", myConnection);
DataSet
