body: <p>How can I change the background color of a GridView cell using IIF and EVAL? </p>
  
  <p>I thought it would be something like this, but it does not seem to work.</p>
  
  <pre><code>&lt;asp:TextBox 
     ID="textbox1" 
     runat="server" 
     Text='&lt;%# Eval("Field1") %&gt;' 
     Width="100px" 
     visible="false" 
     BackColor='&lt;%# IIF(Eval("Field1")&gt;5,"Red","Blue") %&gt;'&gt;
  &lt;/asp:TextBox&gt;
  </code></pre>
  
  <p>Thank you,</p>
