Question

How can I change the background color of a GridView cell using IIF and EVAL?

I thought it would be something like this, but it does not seem to work.

<asp:TextBox 
   ID="textbox1" 
   runat="server" 
   Text='<%# Eval("Field1") %>' 
   Width="100px" 
   visible="false" 
   BackColor='<%# IIF(Eval("Field1")>5,"Red","Blue") %>'>
</asp:TextBox>

Thank you,

Replace Red and Blue string constant with color objects.

BackColor='<%# IIF(Eval("Field1")>5,System.Drawing.Color.Red,System.Drawing.Color.Blue) %>'>

Or

BackColor='<%# IIF(Integer.Parse(Eval("Field1").ToString())>5,System.Drawing.Color.Red,System.Drawing.Color.Blue) %>'>
