WPF ListView/GridView绑定 [英] WPF ListView/GridView Binding

问题描述

我正在尝试制作一个简单的VS 2017扩展程序，该扩展程序将一个对象并显示它.我有数据返回并在文本框中显示json，所以我知道数据正确返回了.但是由于某种原因，gv只是两次显示单词"id"，因为它们是数据集中的两条记录.我已经尝试了很多事情，而这些事情都是我所无法企及的.加上文档似乎无处不在.

I am attempting to make a simple VS 2017 Extension that is taking a object and displaying it. I have the data coming back and displaying the json in a text box, so I know the data is coming back correctly. But for some reason the gv is just showing the word "id" twice, as their are two records in the dataset. I have tried so many things I'm loosing track. Plus the documentation seems to be all over the place.

我相信这里至少可能有2个问题...

I believe there could be at least 2 issues here...

1)XAML的绑定"

1) XAML the "Bindings"

2)绑定数据或将数据添加到LV?

2) Binding or adding the data to the LV?

任何对此的帮助将不胜感激！

Any help with this would be greatly appreciated!

    private void PopulateListView()

        txtJson.Text = JsonConvert.SerializeObject(l);

        foreach (var p in l)
        {
            LvIssues.Items.Add(p);

推荐答案

您需要设置ListView.ItemsSource.

you need to set the ListView.ItemsSource.

private void PopulateListView()
{
    var l = GetPeople();
    txtJson.Text = JsonConvert.SerializeObject(l);

    LvIssues.ItemsSource= l;
}

<ListView x:Name="LvIssues">
            <ListView.View>
                <GridView>
                    <GridView.Columns>
                        <GridViewColumn Width="Auto" Header="Id"  DisplayMemberBinding="{Binding Id}"></GridViewColumn>
                    </GridView.Columns>
                </GridView>
            </ListView.View>
        </ListView>
