I've made a dynamic content control using the DynamicContentPlugIn attribute. I have one control for edit as well as the control used for rendering the content. It works well as long as all I want is for the dynamic content placeholder to render as a block element in the editor, but it won't render inline. I've tried to implement IDynamicContentDisplayType in both my controls but RenderAsBlockElement is never called in either of them. Is there something I'm missing?

[DynamicContentPlugIn(
        DisplayName = "Name",
        Url = "EditControl.ascx",
        ViewUrl = "Control.ascx")]
public partial class MyClass: UserControl, IDynamicContentDisplayType
{
    /*Code here*/

    public bool RenderAsBlockElement { get { return false; } }
}

public partial class MyClassEdit : DynamicContentEditControl, IDynamicContentDisplayType
{
    public override void PrepareForSave()
    {
        Content.Properties[ "SelectedValue" ].Value = SelectedValue;
    }

    public bool RenderAsBlockElement { get { return false; } }
}
