LinqDataSource Using Enum In Where?

Not sure where the best place to ask this question is so I will ask it here.  I am trying to use the LinqDataSource ASP.NET 3.5 control and am having a problem with using the Where attribute.  I have a field that I want to filter on that is an Enumeration, however if I try to put the integer value in the Where attribute the page will not compile.  How do I use enum values in the Where attribute?

I have something like this:

public enum EventType
{
    Charger = 0,
    Location = 1,
    Scanner = 2

}

I want to filter the LinqDataSource like this:

<asp:LinqDataSource ID="DataSource1" runat="server"
        ContextTypeName="MyDataContext"
        Table="Events"
        Where="EventType = 2" />

This won't work.  The EventType property is an instance of the enum type above.
