我们需要给用户很多标签,我们需要使用一个控件,他的长度是变化,可以快速放,这样好像wrapPancel就是我们需要,因为这个我直接写如果看起来不懂,可以看

win10 UWP 标签

我们点添加就会添加标签,我们删除标签就很快排版。

我们使用RichBox,这个可以做我们标签

源代码因为作者写的和UWP不一样,我改UWP,放在https://github.com/lindexi/TagList

运行效果

软件使用,先add

win10 UWP 标签

跳到让用户选择,这里如果让用户输入,使用有点难,可以使用用户在跳转输入,输入自动变为预设一样

源.Add(new Tag() {Id = "id",Label = "用户输入"});

标签使用在跳转MainPage

if (e.NavigationMode == NavigationMode.Back)

我们把选择保存

General.GetInstance().TagSelection

SetTags是本算法的主要

我们搜索全部新加和被删除

var tagParagraph = (Paragraph) (from paragraph in TagRichTextBlock.Blocks
    where paragraph.Name.StartsWith("Tags")
    select paragraph).FirstOrDefault();

var tagIds = from tag in General.GetInstance().TagSelection.Tags
    select tag.Id;

var buttonsToRemove = from item in tagParagraph.Inlines.Cast<InlineUIContainer>()
    where !tagIds.Contains(((Button) item.Child).Name)
    select item;

foreach (InlineUIContainer container in buttonsToRemove)
    tagParagraph.Inlines.Remove(container);
IEnumerable<string> buttonIds = from item in tagParagraph.Inlines.Cast<InlineUIContainer>()
                    select ((Button) item.Child).Name;

                IEnumerable<Tag> tagsToAdd = from item in General.GetInstance().TagSelection.Tags
                    where !buttonIds.Contains(item.Id)
                    select item;

                foreach (Tag tag in tagsToAdd)
                {
                    InlineUIContainer container = new InlineUIContainer();
                    RichTextBlock inlineRichTextBlock = new RichTextBlock()
                    {
                        IsTextSelectionEnabled = false
                    };
                    Paragraph inlineParagraph = new Paragraph();
                    inlineParagraph.Inlines.Add(new Run()
                    {
                        Text = string.Format("{0} ", tag.Label),
                        FontSize = 14
                    });
                    inlineParagraph.Inlines.Add(new Run()
                    {
                        Text = "\uE106",
                        FontFamily = new FontFamily("Segoe UI Symbol"),
                        FontSize = 10
                    });
                    inlineRichTextBlock.Blocks.Add(inlineParagraph);

                    Button tagButton = new Button()
                    {
                        Content = inlineRichTextBlock,
                        Style = (Style) Application.Current.Resources["TagButtonStyle"],
                        Name = tag.Id
                    };
                    tagButton.Click += OnTagButtonClicked;
                    container.Child = tagButton;

                    tagParagraph.Inlines.Add(container);
                }

点击删除按钮,删除id

            string tagId = ((Button) sender).Name;
            General.GetInstance()
                .TagSelection.Tags.Remove(General.GetInstance().TagSelection.Tags.Single(item => item.Id.Equals(tagId)));
            SetTags();
