WPF：多用户调度程序

Question

我意识到Outlook就像调度程序一样。我以http://www.codeproject.com/Articles/30881/Creating-an-Outlook-Calendar-Using-WPF-Part-2作为基础，但我的日历应该有一些用户数量的显示数据列。当然，我可以通过XAML添加一些用户列，但这是静态解决方案，我不知道我的程序会显示多少用户。

如何改进此程序以添加用户的动态计数，或者可能还有其他一些开源WPF控件？

XAML的日历样式代码，在下一个中创建3个静态列：

 <Style TargetType="{x:Type local:Calendar}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type local:Calendar}">
                    <Border Background="#E3EFFF"
                            BorderBrush="#6593CF"
                            BorderThickness="2,2,2,2">
                        <Grid>

                                <ColumnDefinition Width="*" />
                            </Grid.ColumnDefinitions>
