Conditional Processing

[Wayne Wengert]

In a Datagrid I have a field (<td>) in which I want to display a link if a
database field is still Null but I want to display a blank (&nbsp;) if that
DB field has a value. If I try to put the "..If ...Then..) within the TD it
simply displays that as text. I am not sure how to code this conditon? What
I am trying to accomplish is something like the following. I want to test
the "status" field for the condition.

<td>
If <%# DataBinder.Eval(Container.DataItem,"status") %> Is Null Then
<asp:HyperLink id="XX" runat="server" NavigateUrl= '<%#
"httpxyz.com/evaljudge.asp?name=" +
DataBinder.Eval(Container.DataItem,"JudgeName") + "&caption=" +
DataBinder.Eval(Container.DataItem,"Caption") + "&evalid=" + evalID %>'
Text= "Evaluate" >
</asp:HyperLink>
Else
&nbsp;
End If
</td>

Seems your condition code would be best in the OnItemCreated event or the
OnItemDataBound event.

If e.Item.Cells(1).Value = 1 Then ...

Thanks Steve. I'll get that article and see if I can apply it.
