超链接字段为空，而出口的GridView为PDF [英] Hyperlink field is empty while exporting gridview to PDF

问题描述

我在ASP.NET工作。我有一个 GridView控件，致使其2是列超链接（其余为 regulardatafield ）。
他们看起来像：

I work in ASP.NET. I have a gridview, that 2 of it's columns are hyperlinks (the others are regulardatafield). they look like that:

 <asp:TemplateField HeaderText="Costumer">
            <ItemTemplate>
                <asp:HyperLink ID="HyperLink1" runat="server" 
                    NavigateUrl='<%# Eval("CUSTOMER_ID", "javascript:void(window.open(&#039;CustSubsDetailsPage.aspx?CUSTOMER_ID={0}&#039;,&#039;&#039;,&#039; width=500, height=500, top=100, left=100&#039;))") %>' 
                    Text='<%# Eval("CUSTOMER_ID") %>'></asp:HyperLink>
            </ItemTemplate>
        </asp:TemplateField>

在CS code我只使用数据绑定，然后导出到 PDF 。
一切正常perfectrly除2列是空的。

In the cs code i only use databind, and then export to pdf. Everything works perfectrly except those 2 columns that are empty.

修改这里要求的是code为PDF文件：

EDIT as requested here is the code for the pdf file:

protected void btnExportPDF_Click(object sender, EventArgs e)
{
    GridView.AllowPaging = false;
    GridView.DataBind();

    iTextSharp.text.pdf.PdfPTable table = new iTextSharp.text.pdf.PdfPTable(GridView.Columns.Count);
    table.WidthPercentage = 90;
    table.RunDirection = PdfWriter.RUN_DIRECTION_RTL;

     for (int i = 0; i < GridView.Columns.Count; i++)
    {
        string cellText = headers[i];
        BaseFont bf = BaseFont.CreateFont("C:\\Windows\\Fonts\\Arial.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
        iTextSharp.text.Font font = new iTextSharp.text.Font(bf, 6, iTextSharp.text.Font.NORMAL, BaseColor.BLACK);
        iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(new Phrase(8, cellText, font));
        table.AddCell(cell);
    }
    for (int i = 0; i < GridView.Rows.Count; i++)
    {
        if (GridView.Rows[i].RowType == DataControlRowType.DataRow)
        {
            for (int j = 0; j < GridView.Columns.Count; j++)
            {
                string cellText = Server.HtmlDecode(GridView.Rows[i].Cells[j].Text);
                BaseFont bf = BaseFont.CreateFont("C:\\Windows\\Fonts\\Arial.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
                iTextSharp.text.Font font = new iTextSharp.text.Font(bf, 6, iTextSharp.text.Font.NORMAL, BaseColor.BLACK);
                iTextSharp.text.pdf.PdfPCell cell = new iTextSharp.text.pdf.PdfPCell(new Phrase(8, cellText, font));
                table.AddCell(cell);
            }
        }
    }

    Document pdfDoc = new Document(PageSize.A4_LANDSCAPE, 10f, 10f, 10f, 0f);
    PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
    pdfDoc.Open();
    pdfDoc.Add(table);
    pdfDoc.Close();
    Response.ContentType = "application/pdf";
    Response.AddHeader("content-disposition", "attachment;" + "filename=Dlf_Log_report_" + DateTime.Now + ".pdf");
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    Response.Write(pdfDoc);
    Response.End();
}

能否请你帮我找出这个问题？
先谢谢了。

Can you please help me figure out the problem? Thanks in advance.

推荐答案

属性文本不能用于的ItemTemplate 。您应该使用以下code对这些列：

Property Text cannot be used for ItemTemplate. You should use the following code for such columns:

string cellText = Server.HtmlDecode((GridView.Rows[i].Cells[j].FindControl("hyperLinkId") as HyperLink).NavigateUrl);
