【问题描述】：
我制定了一个如下所示的自定义时间表，它可以正常工作，但现在我正在尝试添加活动/约会，但我终生无法弄清楚如何做到这一点。我希望能够单击日历上的一个按钮（日期），创建约会/事件，然后将事件的标题添加到在正确的网格单元（日期）上为其创建的 txtblock（网格单元）在日历上。我不知道如何通过单击指定的按钮来访问某个网格单元。我不会为这段代码的编写方式感到自豪。我最初想要一个 MVVM，但现在这个工作。我必须解决的问题是每次我单击 按钮更改月份时，都会生成一个新月份并删除旧月份。所以一次只制作一个月。请提供任何帮助。
wpf 的一部分：使用 ItemsControl
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel>
<Button Content="{Binding day}" Width="175" HorizontalAlignment="Stretch" VerticalAlignment="Top" VerticalContentAlignment="Top" HorizontalContentAlignment="Left" Name="btnCalenderDate" Click="btnCalenderDate_Click" Loaded="btnCalenderDate_Loaded" Height="18" FontSize="10" FontWeight="Bold">
</Button>
<TextBlock OpacityMask="Black" Name="txtBlockdays" VerticalAlignment="Top" TextWrapping="Wrap">
</TextBlock>
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
<!-- ItemContainerStyle -->
<ItemsControl.ItemContainerStyle>
<Style >
<Setter Property="Grid.Column" Value="{Binding WeekDay}" />
<Setter Property="Grid.Row" Value="{Binding WeekNo}" />
</Style>
</ItemsControl.ItemContainerStyle>
