ASP.Net repeater control - using conditional statements

Question

I am trying to use an if statement inside of a repeater control and receiving an InvalidOperationException on the if.

What I'm trying to do is run a block of code inside the repeater only if the current item has a UserType that is set to Admin.

     <asp:Repeater ID="rptSingleValueHeaders" runat="server">
         <ItemTemplate>
             <% if (Eval("UserType").ToString() == "Admin") { %>
                 <div>
                     do stuff here
                 </div>
            <% } else { %>
                 <div>
                     do other stuff
                 </div>
            <% } %>
         </ItemTemplate>
     </asp:Repeater>

My datasource is defined on the aspx.cs and contains a property named UserType which is of type string. Let me know if I need to provide any more details. Thank you.

Answers in your referenced SO don't apply as I'm trying to evaluate a property coming from my datasource. — noclist, Sep 12 '14 at 18:44
You question is a duplicate anyway. You can find the solution in the link. If not, there are some other questions that fit your requirements too. Just search and you'll find them. — emerson.marini, Sep 12 '14 at 18:45

You could use server side visibility:

<ItemTemplate>
    <div runat="server" visible='<%# (Eval("UserType").ToString() == "Admin") %>'>
        I show this HTML
    </div>
    <div runat="server" visible='<%# (Eval("UserType").ToString() != "Admin") %>'>
        I show this other HTML
    </div>
</ItemTemplate>

Receiving a parser error ---> Cannot create an object of type System.Boolean from its string representation '<% (Eval("UserType").ToString() == "Admin") %>' for the 'Visible' property. – noclist Sep 12 '14 at 18:56
