所以我需要?jiǎng)?chuàng)建一個(gè)自定義按鈕，在我必須創(chuàng)建的網(wǎng)格上，在這個(gè)網(wǎng)格上我需要?jiǎng)?chuàng)建幾個(gè)帶有特定信息的標(biāo)簽。這是我將孩子添加到按鈕的代碼    private void HighlightTodayDay()    {        Label label1 = new Label()        {            BackgroundColor = Color.DarkRed,            Text = "lbl1"        };        Label label2 = new Label()        {            BackgroundColor = Color.Gold,            Text = "lbl2"        };        if ((DateTime.Today.Year == actualVisibleMonth.Year) && (DateTime.Today.Month == actualVisibleMonth.Month))        {            foreach (var child in Children.Reverse())            {                if (child.ClassId.ToString() == ("actualDayButtonID" + DateTime.Today.Day.ToString()) && child.IsEnabled == true)                {                    DayButton todayDayButton = dayButtonsList[DateTime.Today.Day + shiftOfFirstDay];                    todayDayButton.TextColor = Color.FromHex("#0f0");                    //upto this line everything is working as it should                    todayDayButton.insideGrid.Children.Add(label1, 0, 0);  //do nothing                    todayDayButton.insideGrid.Children.Add(label2, 0, 1); //do nothing                    return;                }            }        }    }這是“自定義”按鈕的代碼    class DayButton : Button{    public string EventDate;    public string EventStartTime;    public string EventEndTime;    public string EventShift;    public string EventName;    public string EventDescription;    public Grid insideGrid;    public DayButton()    {        insideGrid = new Grid();        insideGrid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(1, GridUnitType.Star) });        insideGrid.RowDefinitions.Add(new RowDefinition { Height = new GridLength(3, GridUnitType.Star) });        insideGrid.Parent = this;    }}
