Sorting of array in windows phone 7_问答_开发者

I am trying to sort data that i retrieved. I have two data time and attached title. I were able to sort the time. But the attached note did not coordinate with the sorted arrangement.

For example, Time -> 10:45AM Attached title -> Homework 8:45AM -> Work

Sorted on time Time 8:45AM Homework 10:50AM Work

    }

The problem is, you are sorting your time array but not your title array. Just create a new class "ScheduleItem" with three properties called Time, Title and Category. Then create a strongtyped List and do your sorting on the list.

Your class should look like this

public class ScheduleItem : IComparable<ScheduleItem>
{
    public DateTime Time { get; set; }
    public string Title { get; set; }
    public string Category { get; set; }


    public int CompareTo(ScheduleItem item)
    {
        return Title.CompareTo(item.Title);
    }
}

After that you can read your values from your files and build up your list like this.

if (scheduleListBox.Items.Count == 0)
{

    List<ScheduleItem> scheduleItems = new List<ScheduleItem>();
    for (int i = 0; i < timeSplit.Length; i++)
    {
        string timeList = timeSplit[i];
        string titleList = titleSplit[i];
        string categoryList = categorySplit[i];

        ScheduleItem item = new ScheduleItem
                                {
                                    Time = DateTime.Parse(timeList),
                                    Title = titleList,
                                    Category = categoryList
                                };
        scheduleItems.Add(item);

    }

    scheduleItems.Sort();
}

And now iterate through your list of ScheduleItems and build your controls. Your code should look something like this

if (scheduleListBox.Items.Count == 0)
{

    List<ScheduleItem> scheduleItems = new List<ScheduleItem>();
    for (int i = 0; i < timeSplit.Length; i++)
    {
        string timeList = timeSplit[i];
        string titleList = titleSplit[i];
        string categoryList = categorySplit[i];

        ScheduleItem item = new ScheduleItem
                                {
                                    Time = DateTime.Parse(timeList),
                                    Title = titleList,
                                    Category = categoryList
                                };
        scheduleItems.Add(item);

    }

    scheduleItems.Sort();

    foreach (ScheduleItem item in scheduleItems)
    {

        //Define grid column, size
        Grid schedule = new Grid();
        //Column to hold the time of the schedule
        ColumnDefinition timeColumn = new ColumnDefinition();
        GridLength timeGrid = new GridLength(110);
        timeColumn.Width = timeGrid;
        schedule.ColumnDefinitions.Add(timeColumn);


        //Text block that show the time of the schedule
        TextBlock timeTxtBlock = new TextBlock();
        timeTxtBlock.Text = item.Time;
        //Set the alarm label text block properties - margin, fontsize
        timeTxtBlock.FontSize = 28;
        timeTxtBlock.Margin = new Thickness(0, 20, 0, 0);
        //Set the column that will hold the time of the schedule
        Grid.SetColumn(timeTxtBlock, 0);
        schedule.Children.Add(timeTxtBlock);



        //Column to hold the title of the schedule
        ColumnDefinition titleColumn = new ColumnDefinition();
        GridLength titleGrid = new GridLength(300);
        titleColumn.Width = titleGrid;
        schedule.ColumnDefinitions.Add(titleColumn);

        //Text block that show the title of the schedule
        TextBlock titleTxtBlock = new TextBlock();
        titleTxtBlock.Text = item.Title;

        if (item.Title.Length > 15)
        {
            string strTitle = item.Title.Substring(0, 15) + "....";
            titleTxtBlock.Text = strTitle;
        }
        else
        {
            titleTxtBlock.Text = item.Title;
        }
        //Set the alarm label text block properties - margin, fontsize
        titleTxtBlock.FontSize = 28;
        titleTxtBlock.Margin = new Thickness(20, 20, 0, 0);
        //Set the column that will hold the title of the schedule
        Grid.SetColumn(titleTxtBlock, 1);
        schedule.Children.Add(titleTxtBlock);



        //Column 3 to hold the image category of the schedule
        ColumnDefinition categoryImageColumn = new ColumnDefinition();
        GridLength catImgnGrid = new GridLength(70);
        categoryImageColumn.Width = catImgnGrid;
        schedule.ColumnDefinitions.Add(categoryImageColumn);

        //Text block that show the category of the schedule
        TextBlock categoryTxtBlock = new TextBlock();
        categoryTxtBlock.Text = item.Category;

        //set the category image and its properties - margin, width, height, name, background, font size
        Image categoryImage = new Image();
        categoryImage.Margin = new Thickness(-20, 15, 0, 0);
        categoryImage.Width = 50;
        categoryImage.Height = 50;
        if (categoryTxtBlock.Text == "Priority")
        {
            categoryImage.Source = new BitmapImage(new Uri("/AlarmClock;component/Images/exclamination_mark.png", UriKind.Relative));
        }
        else
            if (categoryTxtBlock.Text == "Favourite")
            {
                categoryImage.Source = new BitmapImage(new Uri("/AlarmClock;component/Images/star_full.png", UriKind.Relative));
            }
