Question

asp.net links from database table - VB.net, MS Access, asp.net, gridview

Asked by: MHenry

I'm trying to read links from an Access database and then use those to generate html links in a gridview.

I've tried several variations on this, but I haven't found one that works:
              <asp:TemplateField HeaderText="Link">
                   <ItemTemplate>
              <asp:HyperLink runat="server" NavigateUrl='<%# "http://" + Eval("ref_page") %>'
             Text='<%# Eval("textLink") %>' />
                  </ItemTemplate>
            </asp:TemplateField>


I keep getting this error each time:
  <a disabled="disabled">Some Link Here</a>


Not sure what I'm doing wrong or why it's showing as disabled. Any help would be much appreciated.

Best,
MH

hey you said some link here,,is that link from you DB ref_page...?

 

by: MHenryPosted on 2009-09-14 at 12:38:28ID: 25328566

Yes, that was just an example of what's coming back.

The text portion is working fine. The link though is coming back as   <a disabled="disabled">

 

by: CodeCruiserPosted on 2009-09-15 at 07:09:42ID: 25335030

Try this

NavigateUrl='<%# Eval("http://{0}", "ref_page") %>'

 

by: MHenryPosted on 2009-09-15 at 07:46:32ID: 25335463

That throws this error:
'System.Data.DataRowView' does not contain a property with the name 'http://{0}ref_page'

 

by: MHenryPosted on 2009-09-15 at 07:47:29ID: 25335471

sorry, this error:
'System.Data.DataRowView' does not contain a property with the name 'http://{0}'.

 

by: MHenryPosted on 2009-09-15 at 08:31:57ID: 25336015

The actual problem was further up in the code. Somehow, I got Enabled="False" in the gridview code. I don't know how that crept in but I deleted that and now the links work.

Sheesh!

 

by: DeathracePosted on 2009-09-15 at 12:50:13ID: 25338624

ok cool...finally resolved..

 

by: CodeCruiserPosted on 2009-09-15 at 13:22:28ID: 25338981

By the way, i think i got the order of the parameters to Eval wrong.

 

by: MHenryPosted on 2009-09-15 at 13:25:49ID: 25339015

I just went back to what I started with:
<asp:HyperLink runat="server" NavigateUrl='<%# "http://" + Eval("ref_page") %>'
             Text='<%# Eval("textLink") %>' />

works fine now that I removed the Enabled="False"
