[UWP] [VB] CalendarView重复CalendarViewDayItem更改

问题描述

您好。  我已在CalendarViewDayItemChanging中实现了代码，以更改某些日期背景颜色。  代码可以找到，但颜色会在日历视图中的后续日期重复显示。  例如，我在12月21日的背景下更改
。  相同的背景将出现在次年的3月，然后是6月，然后是9月和之后。  为了验证代码是否正常工作，我将更改日期
输出到调试器窗口，12月21日是唯一更改的日期。  有什么我做错了或者这是CalendarView中的问题？  代码如下。  感谢您的帮助。

Hello.  I have implemented code in the CalendarViewDayItemChanging to change certain dates background color.  The code works find, although the colors are repeating themselves in later dates in the Calendar view.  For example, I change the background of December 21st.  The same background will appear on day in March of the following year and then again in June and then again in September and on and on.  To verify the code is working correctly, I have the dates that are changed output to the debugger window and December 21st is the only date that gets changed.  Is there something I'm doing wrong or is this a problem in the CalendarView?  The code is below.  Thanks for any help.

 If (Date.Compare(Date.Parse(Date.Parse(dd.Item(i).field1).ToString("yyyy-MM-dd")), Date.Parse(args.Item.Date.ToLocalTime.ToString("yyyy-MM-dd"))) = 0) Then

                        Debug.WriteLine("Date  Match " & args.Item.Date.ToLocalTime.ToString("yyyy-MM-dd"))

                        If CInt(dd.Item(i).field3) > 0 Then

                            If (CInt(dd.Item(i).field4) > 0) Then

                                args.Item.Background = New SolidColorBrush(Windows.UI.Colors.LightGreen)

                            ElseIf (CInt(dd.Item(i).field5) > 0) Then

                                args.Item.Background = New SolidColorBrush(Windows.UI.Colors.LightYellow)

                            ElseIf (CInt(dd.Item(i).field6) > 0) Then

                                args.Item.Background = New SolidColorBrush(Windows.UI.Colors.LightPink)

                            End If

                        ElseIf CInt(dd.Item(i).field2) > 0 Then

                            args.Item.Background = New SolidColorBrush(Windows.UI.Colors.LightSlateGray)

                        End If

                    End If

我们需要知道你项目的类型，你需要自己为标题添加标签。

We need to know your project's type, and you would need to add tag to title by yourself.

我检查了你的代码，但我无法理解"某些日期"是什么。什么是"dd.Item（i）.field1"？

I have checked your code, but I could not understand what the "certain dates" is. And what’s the "dd.Item(i).field1"?

请提供有关您问题的更多详细信息。
