嘿傢伙我已經做了一個像下面的自定義時間表，它的工作原理和所有，但現在我試圖添加事件/約會，我無法弄清楚我的生活怎麼辦這個。我希望能夠點擊日曆上的某個按鈕（日期），創建約會/事件，然後將事件標題添加到在正確的gridcell（日期）上創建的txtblock（gridcell）在日曆上。我無法弄清楚如何通過點擊指定的按鈕來訪問特定的網格單元格。我不會爲代碼的寫法感到自豪。我原本想要有一個MVVM，但現在工作。這個問題我不得不每次點擊<或>按鈕來改變月份，新的月份被創建並且舊的被刪除。所以一次只有一個月。請任何幫助表示讚賞。 WPF的爲自定義日曆創建活動/約會WPF
部分：使用ItemsControl的
<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>
