c# - 为自定义日历 WPF 创建事件/约会

Question

我制定了一个如下所示的自定义时间表并且它有效但现在我正在尝试添加事件/约会并且我无法弄清楚我的生活如何做到这一点。我希望能够单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为正确的网格单元(日期)创建的 txtblock(网格单元)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编写方式感到自豪。我最初想要一个 MVVM，但现在可以用了。我不得不遇到的问题是每次我单击 < 或 > 按钮更改月份时，都会创建一个新月份并删除旧月份。所以一次只能制作一个月。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>

我不太确定您要做什么，但您是否考虑过使用 DataGrid.HitTest Method这可能是更好的方法。您可以使用鼠标点作为 HitTest 参数，它会为您提供行和列。
