Hyperlink field is empty while exporting gridview to PDF

Question

I work in ASP.NET 4 C#.

 

I have a GridView, that one of it's columns is HyperLink (the others are regular BoundField).

 

Now I need export this GridView in pdf and I have worked with iTextSharp library http://technico.qnownow.com/export-gridview-data-pdf-using-itextsharp/

 

They look like that:

 

[code]

<asp:TemplateField HeaderText="link" ItemStyle-HorizontalAlign="Center">

<ItemTemplate>

<asp:HyperLink ID="link" runat="server" NavigateUrl='<%# Eval("link").ToString() %>'

ImageUrl='<%#(String.IsNullOrEmpty(Eval("link").ToString()) ? "/Images/cross-button.png" : "/Images/download.gif")%>'

ToolTip='<%#(String.IsNullOrEmpty(Eval("link").ToString()) ? "empty link" : "go to link")%>'

Target="_blank" BorderStyle="None" ForeColor="Transparent">

</asp:HyperLink>

</ItemTemplate>

</asp:TemplateField>[/code]

 

In the code-behind I only use databind, and then export to pdf.

 

Everything works perfectly except this one column that is empty.

 

I have tried to replace:

 

 [code]

cellText = Server.HtmlDecode(gvProducts.Rows[rowIndex].Cells[j].Text);[/code]

 

with

 

[code] 

cellText = Server.HtmlDecode((gvProducts.Rows[rowIndex].Cells[j].FindControl("link") as HyperLink).NavigateUrl);[/code]

 

But in output pdf in all columns I have the value of HyperLink.

 

Can you please help me figure out the problem?

 

Thanks in advance.

 

My code below.

 

[code] 

//export rows from GridView to table

for (int rowIndex = 0; rowIndex < gvProducts.Rows.Count; rowIndex++)

{

if (gvProducts.Rows[rowIndex].RowType == DataControlRowType.DataRow)

{

for (int j = 0; j < gvProducts.Columns.Count - 1; j++)

{

//fetch the column value of the current row

//cellText = Server.HtmlDecode(gvProducts.Rows[rowIndex].Cells[j].Text);

cellText = Server.HtmlDecode((gvProducts.Rows[rowIndex].Cells[j].FindControl("link") as HyperLink).NavigateUrl);

//create a new cell with column value

//cell = new PdfPCell(new Phrase(cellText));

cell = new PdfPCell(new Phrase(cellText, FontFactory.GetFont("nina fett", 8)));

//Set Color of Alternating row

if (rowIndex % 2 != 0)

{

cell.BackgroundColor = new BaseColor(System.Drawing.ColorTranslator.FromHtml("#9ab2ca"));

}

else

{

cell.BackgroundColor = new BaseColor(System.Drawing.ColorTranslator.FromHtml("#f1f5f6"));

}

//add the cell to the table

table.AddCell(cell);

}

}

}[/code]
