Binding DataGridComboBox to Enum

I'm Currently Binding my Datagrid to a DTO. It's able to pull up values EXCEPT the enumeration. How Do I bind enumerations when the values coming in don't quite equal the enumeration.

public enum Channels { Phone, Website, Email, Skype, Cell, Fax }

But the possible values for Channel are Between 0-5 

<DataGrid ItemsSource={Binding ContactMethods} >
    <DataGridComboBoxColumn  
         Header="Type" 
         SelectedItemBinding="{Binding Channel, Mode=TwoWay}" 
         shell:EnumHelper.Enum="{x:Type clients:ContactMethods+Channels}" 
         DisplayMemberPath="Channel"/>

To get all values of an enum in XAML you can use an ObjectDataProvider like:

<ObjectDataProvider x:Key="MyEnumDataProvider" MethodName="GetValues" ObjectType="{x:Type System:Enum}">
    <ObjectDataProvider.MethodParameters>
        <x:Type TypeName="NameSpaceOfMyEnum:MyEnum"/>
    </ObjectDataProvider.MethodParameters>
</ObjectDataProvider>

To display the enum-values for example in a ComboBox (that's where I use this) you have to:

ItemsSource="{Binding Source={StaticResource MyEnumDataProvider}}"

I've created a new Window and added an ObjectDataProvider in the Window.Resources. The xaml is:

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:System="clr-namespace:System;assembly=mscorlib"
        xmlns:wpfApplication1="clr-namespace:WpfApplication1"
        Title="MainWindow" Height="100" Width="250">
    <Window.Resources>
        <ObjectDataProvider x:Key="MyEnumDataProvider" MethodName="GetValues" ObjectType="{x:Type System:Enum}">
            <ObjectDataProvider.MethodParameters>
                <x:Type TypeName="wpfApplication1:MyEnum"/>
            </ObjectDataProvider.MethodParameters>
        </ObjectDataProvider>
    </Window.Resources>
    <ComboBox ItemsSource="{Binding Source={StaticResource MyEnumDataProvider}}"></ComboBox>
</Window>

The enum is just

enum MyEnum
{
    EnumValue1,
    EnumValue2,
    EnumValue3,
}

I think your xaml from the comment works if you add

xmlns:System="clr-namespace:System;assembly=mscorlib"
xmlns:wpfApplication1="clr-namespace:WpfApplication1"

to your Namespaces of the window. The wpfApplication1 must by modified to match the namespace of your enum

public enum Channels { Phone, Website, Email, Skype, Cell, Fax }
var ChannelsForBind = Enum.GetValues(typeof(Channels)).Cast<Channels>();
