Using a table in ASP.NET

I have a table that (in a user control) that holds 2 columns and a bunch of rows. There is one row I need to populate when theres a value(not a problem) but when there is no value I want to collapse the <tr> and move on. There are controls in the tr like a label on one column and a text box holds the value and there is also a placeholder control. All I want to do is collapse(?) the row when there is no value. I see alot of javascript out there that does this but Im new to all this so Im not sure how to call the script or where to put the script(in the control or on the form that holds the user control?)
Can someone please help with this. I am trying to figure it out in the source code but I havent been able to do it just yet.
Im using ASP.NET 2012 .NET 4.0(VB source code)

Maybe you can adapt this .

   Private Sub TestGridView_DataBindingComplete(ByVal sender As Object, _
    ByVal e As DataGridViewBindingCompleteEventArgs) _
    Handles DataGridView1.DataBindingComplete
        For Each Row As DataGridViewRow In CType(sender, DataGridView).Rows
            Dim Visible As Boolean = True
            'Do this to inspect all cells in the row
            For i As Integer = 0 To Row.Cells.Count - 1
                If Row.Cells(i).Value Is Nothing Then
                    Visible = False
                    Exit For
                End If
            'Or you can check specific columns for their values
            If Row.Cells(0).Value Is Nothing OrElse _
            (IsNumeric(Row.Cells(0).Value) AndAlso CInt(Row.Cells(0).Value) < 0) Then
                Visible = False
            End If
            Row.Visible = Visible
    End Sub

Open in new window

i would check in asp if there is data, if true,  then add row,  else dont add row.

or are you trying to do a fancy css where the thung collapses like an accordion
basically if you choose option 1, move the TR tag inside your asp code

so instead of

<tr><td>  <asp: value stuff> </td></tr>

you would do something like

 <asp..  if value exists  "<tr><td>" & valuestuff& "</td></tr>"   >

Randy, Im using a table not a gridview. Although, I though of converting the table into a grid but I dont have the time to do so. I simply want to keep the designated row at the original height and when populating the table with data, if there is no data for this row I would like to collapse it. I have another question as well. If there is a value I add a link to the <td> and I want to open up a new window with that is already in place. I just dont have the syntax down yet. Here is what I had given to me...
--first argument is an id and the second is supposed to be the screen resolution but I will figure that out. I just need to know if that is the right syntax to open up a new page? I will post a new question for this one...
"<a id="PcovIndivControl1_PcovAllNamesLink" class="PcovIndivLabelsBold"  onclick="OpenNewWindow('20140501060253390384276WBGZW2551       263','')" href="#">Additional Names on File. Click Here to view...</a>"
Maybe you can adapt this. They are hiding based on a value you will want to hide based on null, maybe.

The complete sample project is available in the DevExpress Code Examples database at

The following example demonstrates how to hide particular rows and columns by handling the CustomFieldValueCells Event.

In this example, the event handler iterates through all row headers and removes rows that correspond to the "Employee B" field value, and that are not Total Rows.

Randy, I appreciate your help but once again, I am not using a grid....I am using an html table and I dont have these properties with the table ...
to open a new window use the tag  _default
