ListView控件/列表过滤器的Windows Phone 8.1 C＃ [英] ListView / List Filter Windows Phone 8.1 C#

问题描述

我有一个数据列表

public class PopImage
{
    public async Task<List<PopImage>> PopDatas()
    {
        string imgfolder = "PopularImages";
        var data = new List<PopImage>();
        StorageFolder folder = Windows.ApplicationModel.Package.Current.InstalledLocation;
        StorageFolder subfolder = await folder.GetFolderAsync(imgfolder);

        var files = await subfolder.GetFilesAsync();
        foreach (var items in files)
        {
            data.Add(new PopImage(imgfolder+"/"+items.DisplayName+ ".jpg", items.DisplayName));
        }

        return data;
    }

    public PopImage(string imagePath, string imageName)
    {
        ImagePath = imagePath;
        ImageName = imageName;
    }

    public string ImagePath { get; set; }
    public string ImageName { get; set; }
}

我要添加一个文本框和过滤，如果文本框TextChanged，
我需要做什么应用呢？

I want to add a textbox and filter it if textbox textchanged, what do I need to apply it?

推荐答案

您需要一个TextChanged事件添加到您的文本框。
首先在你的XAML补充一点：

You need to add a TextChanged event to your TextBox. First in your XAML add this:

<TextBox Name="tbListFilter" TextChanged="tbListFilter_TextChanged"/>

然后code后面的是：

Then the code behind is:

private void tbListFilter_TextChanged(object sender, TextChangedEventArgs e)
{
     yourFilteredList = yourPopImageList.Where(p => p.ImageName.ToUpper().Contains(tbListFilter.Text.ToUpper())).ToList();
}
