Question

I have the following case:

I store a specific path in my web.config file like this:

<add key="pdfPath" value="domainName/aa/pdf/"/>

and I want to eval this value in my hyperlink in my DetailsView:

 <asp:TemplateField HeaderText="pdf file">
 <asp:HyperLink ID="hl_link" runat="server" NavigateUrl='<%#Eval("thevaluefromConfigfile")%>'><%#Eval("filename") %></asp:HyperLink>
 </asp:TemplateField>

1. How do I read the value from my configuration file?

2. I want this link to open in a new window. Is the hyperlink the best
   choice?

Answer 1

Use a A tag instead

<a id="hl_link" target="_blank" 
href='<%#ConfigurationSettings.AppSettings["pdfPath"]%>'><%#Eval("filename") %></a>

how to read the key:

 ConfigurationSettings.AppSettings["pdfPath"];
