Viv,

I'm trying to understand this one:

>Or using ObjectDataProvider:

I hope you can help me work it out.

I have defined my enum in my business object class:

namespace SamaanSystems.IBC.Business
{
	/// <summary>
	/// Summary description for Rate.
	/// </summary>
	public partial class Rate
	{
         public enum RateType : int
         {
            Standard = 1,
            Mail = 2,
            ZipX = 3
         }
	}
}

I am trying to have this enum be used to display the possible options on my Rates form in a combo, so the user will see Standard, Mail and ZipX as the items in the combo list and the values of 1, 2 and 3 respectively will be bound to a property of an entity object. The field is rat_type.

I've stuck this code in my RatesWindow.xaml:

    <ObjectDataProvider x:Key="rateTypes"
                    MethodName="GetValues" 
                    ObjectType="{x:Type sys:Enum}">
        <ObjectDataProvider.MethodParameters>
            <x:Type TypeName="local:RateTypes" />
        </ObjectDataProvider.MethodParameters>
    </ObjectDataProvider>

but I get a squiggly blue underline under x:Key="rateTypes" with this error:

Key attribute can be used only on a tag contained in an IDictionary type property

This also cause almost the entire rest of my xaml to be squiggly underlined in blue with this error:

The property 'Content' is set more than once.

So I guess I'm putting this in the wrong place. This is the first bit of my xaml:

<local:ABusinessWindow
	xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
	xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

	x:Name="Window"
	Title="Rates"
	Width="550" Height="450" AllowsTransparency="False" Background="#FFFFFFFF" WindowStartupLocation="CenterScreen" >

    <ObjectDataProvider x:Key="rateTypes"
                    MethodName="GetValues" 
                    ObjectType="{x:Type sys:Enum}">
        <ObjectDataProvider.MethodParameters>
            <x:Type TypeName="local:RateTypes" />
        </ObjectDataProvider.MethodParameters>
    </ObjectDataProvider> 
    
    <mmwpf:mmBusinessWindow.DataContext>
        <SamaanSystems_IBC_Business:RateEntity/>
    </mmwpf:mmBusinessWindow.DataContext>

    <Border>
        <Border.Background>
 ...

Can you explain this a bit for me and tell me where the code should be going?

Thanks very much!
