Question

我有以下代码：

这是我的按钮：<asp:Button ID="Button1" runat="server" Text="Export" />

protected void Button1_Click(object sender, EventArgs e)
    {
        string attachment = string.Empty;
        attachment = "attachment; filename=ReportName" + ".xls"; //Setting the attachment name.
        HttpContext.Current.Response.ClearContent();//clears all content output from the buffer stream.
        HttpContext.Current.Response.AddHeader("content-disposition", attachment);

        HttpContext.Current.Response.ContentType ="application/vnd.ms-excel";
        StringWriter sw = new StringWriter();
        HtmlTextWriter htw = new HtmlTextWriter(sw);
        HtmlForm frm = new HtmlForm();
        htw.WriteLine("<center><b><u><font size='5'> " + attachment + " </font></u></b></center>");//will be displayed in excel as a heading.
        GridView1.Parent.Controls.Add(frm);           
        frm.Controls.Add(GridView1);
        frm.RenderControl(htw);
        HttpContext.Current.Response.Write(sw.ToString());
        HttpContext.Current.Response.Flush();
        HttpContext.Current.Response.End();
    }

但是当我点击按钮时，只有页面正在刷新，没有其他事情发生，请帮帮我

我无法使用此方法：

public override void VerifyRenderingInServerForm(Control control)
{
//base.VerifyRenderingInServerForm(control)
}

public class Customer
{
    public string FirstName { get; set; }
    public string Gender { get; set; }
}

public partial class DetailsViewExample : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if(!Page.IsPostBack)
            BindDetails();
    }

    private void BindDetails()
    {
        DetailsView1.DataSource = new List<Customer> { new Customer { FirstName = "Customer 1", Gender = "Male" } };
        DetailsView1.DataBind();
    }

    protected void DetailsView1_ModeChanging(object sender, DetailsViewModeEventArgs e)
    {
        DetailsView1.ChangeMode(DetailsViewMode.Edit);
        BindDetails();
    }
}
