嘿伙计们我已经制作了一个如下所示的自定义时间表并且它可以工作，但现在我正在尝试添加事件/约会，我无法弄清楚我的生活如何做到这一点。我希望能够点击日历上的其中一个按钮（日期），创建约会/事件，然后将事件的标题添加到在正确的gridcell（日期）上创建的txtblock（gridcell）在日历上。我无法弄清楚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写法感到自豪。我原本想要一个MVVM，但现在这个有用。我必须遇到的问题是每次点击＆lt;或者＆gt;用于更改月份的按钮，将创建新月份并删除旧月份。所以一次只做一个月。请任何帮助表示赞赏。
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>
