Visual Studio .NET - How do I exclude hyperlink fields when hiding detailsview empty rows?

Hello,

I have the following in pageload of detailsview to hide empty fields from displaying.  The problem is it hides hyperlink fields I have as well.  How do I overcome this?  The hyperlink fields are urlstrings page.aspx?id={0}.
 
 protected void dvPersonal_Load(object sender, EventArgs e)
    {
      String data;
      
      foreach (DetailsViewRow r in dvPersonal.Rows)
      {
        if (r.Cells.Count > 1)
        {
          data = r.Cells[1].Text;
        }
        else
        {
          data = r.Cells[0].Text;
        }

        data = data.Replace(" ", "").Trim();
        if (data == null || data == "")
        {
          r.Visible = false;
        }
      }
    }

Thanks,

If it is hiding fields that are null, then your logic is wrong.
Put a breakpoint on each of these lines:

  data = r.Cells[1].Text;

and

  data = r.Cells[1].Text;

and inspect what you see for the value of .Text.

Hello,

an you help me correct the logic?  It works when applied to detailsview onload event, except my hyperlinks do not appear.  I do however want to eliminate future problems I might have and could really use your help. 

In your reply you asked what data was.  For the hyperlink field. it was ""  The other null value are excluded correctly, see OUTPUT.

Thank you,

Hello,

A workaround solution is to make visible the hyperlink row after it was hidden. 

     dvPersonal.Rows[2].Visible = true;

Thanks,
