Using Enums to drive DropDownLists

Published by sethyates at 2:42 am under Development

Mark came up with an idea to use Enums to drive lookups. I told him I could go one better by providing user-friendly names instead of programmer-friendly enum value names. The idea is to loop through the literal fields of the enum type and check for a DescriptionAttribute on each field. Anyway, here’s the source, with caching for top performance.

    not only perfected but optimised and full of 2.0 goodness :)

    Nice one!

    Very nice, but not quite perfect as you could:

    1) Remove the extra namespaces

    using System.Web.UI.WebControls;
    using System.Collections.Generic;

    2) Seal the class
    public sealed class EnumDataSource

    I’m using the current class, so I thought it would fair to post the changes I made to the class.

    Nit picking, I had to add my 2 cents.

    Cheers.

    sorry about that, got posted the wrong namespace
    should have been:

    using System.ComponentModel
    using System.Web.UI.WebControls.

    Cheers
