WPF - Can I use a constant for a resource key name?

Question

<DataTemplate x:Key="MyTemplate" DataType="{x:Type l:MyViewModel}">
    <l:MyView />
</DataTemplate>

Is there any way I can replace the "MyTemplate" with a value from a class of mine?

public sealed class MyTemplateSelector : DataTemplateSelector
{
    public const string TemplateName = "MyTemplate";

    //I use the TemplateName const to retrieve the correct DataTemplate
}

Answer 1

<DataTemplate x:Key="{x:Static l:MyTemplateSelector.TemplateName}"
              DataType="{x:Type l:MyViewModel}">
    <l:MyView />
</DataTemplate>
