I want to declare BaseButton Control in my prjt and extend others from. I create class which inherit System.Windows.Controls.Button and define xaml. In XAML where <ContentPresenter Content="{TemplateBinding Content}"/> i get Error: Content property undefined.

Code behind

public partial class BaseButton : Button
{
    public BaseButton()
    {
        InitializeComponent();
    }
}

XAML:

<Button x:Class="BalComNew.Resource.BalcomUserControl.BaseButton"
        ...
        Name="userControl" Content="{Binding Content, ElementName=userControl}">

    <Button.Style>

        <Style TargetType="Button">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate>
                        <Border>
                            <ContentPresenter Content="{TemplateBinding Content}" />
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

    </Button.Style>
</Button>

Usage:

 <balcomComponent:BaseButton Click="Button_Click">
    <DockPanel>
        Some content here
    </DockPanel>
</balcomComponent:BaseButton>

In XAML where <ContentPresenter Content="{TemplateBinding Content}"/> i get Error: Content property undefined.
