隐藏代码:-

 受保护的 无效 Button1_Click1(对象发​​件人，EventArgs e)
    {
        //  StringWriter sw = new StringWriter(); 
        //  HtmlTextWriter hw =新的HtmlTextWriter(sw); 
        //  this.Literal1.RenderControl(hw); 
        StringReader sr = 新 StringReader(Request.Form [Literal1.UniqueID]);
        文档pdfDoc = 新 Document(PageSize.A4，10f，10f，10f，0f);
        PdfWriter writer = PdfWriter.GetInstance(pdfDoc，Response.OutputStream);
        pdfDoc.Open();
        XMLWorkerHelper.GetInstance().ParseXHtml(writer，pdfDoc，sr);
        pdfDoc.Close();
        Response.ContentType = " ;
        Response.AddHeader(" ，" 附件； filename = HTML.pdf")；
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Write(pdfDoc);
        Response.End();
        //  ScriptManager.RegisterStartupScript(this，this.GetType()，"isActive"，"printGrid();"，true ); 
        modalpop1.Show();
    }

我尝试过的事情:

我试图在modalpop扩展器面板上生成报告，但我想报告导出pdf文件，但按钮不触发.
使用其他方法删除此行

<pre>   <center>
       
        <asp:Button ID="btnGetSelected" runat="server" Text="Generate Report" Style=" margin-left:270px" OnClick="btnGetSelected_Click" />

Code-Behind Code:-

protected void Button1_Click1(object sender, EventArgs e)
    {
        //StringWriter sw = new StringWriter();
        //HtmlTextWriter hw = new HtmlTextWriter(sw);
        //this.Literal1.RenderControl(hw);
        StringReader sr = new StringReader(Request.Form[Literal1.UniqueID]);
        Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 10f, 0f);
        PdfWriter writer = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
        pdfDoc.Open();
        XMLWorkerHelper.GetInstance().ParseXHtml(writer, pdfDoc, sr);
        pdfDoc.Close();
        Response.ContentType = "application/pdf";
        Response.AddHeader("content-disposition", "attachment;filename=HTML.pdf");
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Write(pdfDoc);
        Response.End();
        //ScriptManager.RegisterStartupScript(this, this.GetType(), "isActive", "printGrid();", true);
        modalpop1.Show();
    }

What I have tried:
