Hi Experts.

I have a simple page that displays a data repeater.

My question is.

If there are no records returned how do i NOT display the repeater at all.

I thought maybe
<%  
dim strCount
  strCount = Get_Students1.RecordCount
if strCount < 1 then  %>
 <asp:Repeater DataSource="<%# Get_Students1.DefaultView %>" ID="Repeat1" runat="server">
  <HeaderTemplate>
        <table width="500" style="font: 8pt verdana" border="1">
          <tr style="background-color:DFA894">
            <th>
             First
            </th>
            <th>
              Last
            </th>
            <th>
              DOB
            </th>
            <th>
              M/F
            </th>
                </tr>
 </HeaderTemplate>

      <ItemTemplate>
        <tr style="background-color:FFECD8">
          <td>
            <%# Get_Students1.FieldValue("Surname", Container) %>
          </td>
          <td>
            <%# Get_Students1.FieldValue("GivenNames", Container) %>
          </td>
          <td>
            <%# trim(left(Get_Students1.FieldValue("DateOfBirth", Container),10)) %>&nbsp;
          </td>
          <td>
            <%# Get_Students1.FieldValue("Gender", Container) %>
          </td>
         
        </tr>
      </ItemTemplate>
      <FooterTemplate>
        </table>
      </FooterTemplate>
</asp:Repeater><% end if %>

But I dont know the correct syntax to use

Please Help
Cheers

You could use a gridview which would give you the same layout/results and then use

<asp:GridView ID="GridView1" runat="server" EmptyDataText="nothing to see here">
nothing to see here - would be what the users saw if no data was returned

Thanks for that. Using the gridview can you still have control of the data?

I used repeater because I can munaully code the href links in the output if I need to.

I just found a workaround after reading your post. If i put the if statement inside the headertemplate like this

<HeaderTemplate>
    <table width="500" style="font: 8pt verdana" border="1">
         <%  if Get_Students1.RecordCount > 0 then  %><tr style="background-color:DFA894">
            <th>
             First
            </th>
            <th>
              Last
            </th>
            <th>
              DOB
            </th>
            <th>
              M/F
            </th>
            </tr><% end if %>
 </HeaderTemplate>

it works a treat.

But im assuming its not best practice to do it this way, yes/no?

Thanks again

Dunno about best practise but you can use <ItemTemplate> just like the repeater....

<asp:TemplateField>
<itemstyle width="80px" />
<ItemTemplate>
<a href="<%# eval("someLink")%>">Click me</a>
</ItemTemplate>
</asp:TemplateField>
