如何以编程方式添加多列 ListViewItem 而无需任何数据绑定?

我有一个带有 3 个标头的 ListView,在 XAML 中声明如下:

<ListView Name="myListView">
  <ListView.View>
    <GridView>
      <GridViewColumn Header="H1"/>
      <GridViewColumn Header="H2"/>
      <GridViewColumn Header="H3"/>
    </GridView>
  </ListView.View>
</ListView>

我想以编程方式将 ListViewItem 添加到此 ListView,从而能够设置 ListViewItem 中分别位于第一列、第二列和第三列下的内容。到目前为止,我只得到了这一点:

ListViewItem l = new ListViewItem();
l.Content = "Content";
myListView.Items.Add(l);

这将每一列设置为字符串“Content”。如何更改上面的代码,以便添加一个 ListViewItem,该 ListViewItem 将分别在第一列、第二列和第三列下显示“内容 1”、“内容 2”和“内容 3”?我尝试在 ListViewItem 中查找 SubItem 或 ListViewSubItem 属性,但什么也没找到。

我认为有一个简单的解决方案,但也许我错了。请不要提及数据绑定,因为我只想回答以编程方式设置 Content 属性以反映每列中的单独更改的问题。

非常感谢。

I have a ListView with 3 headers, declared in XAML as follows:

<ListView Name="myListView">
  <ListView.View>
    <GridView>
      <GridViewColumn Header="H1"/>
      <GridViewColumn Header="H2"/>
      <GridViewColumn Header="H3"/>
    </GridView>
  </ListView.View>
</ListView>

I want to programmatically add a ListViewItem to this ListView, being able to set the content within the ListViewItem that will go under the first, second, and third columns individually. So far, I have only gotten this far:

ListViewItem l = new ListViewItem();
l.Content = "Content";
myListView.Items.Add(l);

This sets each column to the string "Content". How can I change the code above so that I can add a ListViewItem that will display "Content 1", "Content 2", and "Content 3" under the first, second, and third columns respectively? I tried to look for a SubItem or ListViewSubItem property within ListViewItem, but found nothing.

I assume there's a simple solution, but maybe I'm wrong. Please do not mention data binding, because I only want an answer to the question of programmatically setting the Content property to reflect individual changes in each column.

Thank you very much.

这不是数据绑定。将 Binding 语句视为为列命名。

<ListView Name="myListView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="H1" DisplayMemberBinding="{Binding Col1}"/>
            <GridViewColumn Header="H2" DisplayMemberBinding="{Binding Col2}"/>
            <GridViewColumn Header="H3" DisplayMemberBinding="{Binding Col3}"/>
        </GridView>
    </ListView.View>
</ListView>

在代码中:

myListView.Items.Add(new { Col1 = "test1", Col2 = "Test2", Col3="test3"});

This is not databinding. Think of the Binding statement as giving the column a name.

<ListView Name="myListView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="H1" DisplayMemberBinding="{Binding Col1}"/>
            <GridViewColumn Header="H2" DisplayMemberBinding="{Binding Col2}"/>
            <GridViewColumn Header="H3" DisplayMemberBinding="{Binding Col3}"/>
        </GridView>
    </ListView.View>
</ListView>

In code:

myListView.Items.Add(new { Col1 = "test1", Col2 = "Test2", Col3="test3"});

中,您将执行以下操作。

您必须先设置列标题,否则将不会显示任何内容。使用字符串数组添加列表视图项目。

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);

        listView1.View=View.Details;
        //Set Columns
        listView1.Columns.Add("Col1");
        listView1.Columns.Add("Col2");
        listView1.Columns.Add("Col3");
        //Fill Rows
        ListViewItem lvi;
        lvi=new ListViewItem(new string[] { "A", "B", "C" });
        listView1.Items.Add(lvi);
        lvi=new ListViewItem(new string[] { "D", "E", "F" });
        listView1.Items.Add(lvi);
        lvi=new ListViewItem(new string[] { "G", "H", "I" });
        listView1.Items.Add(lvi);
    }
}

In here is what you do.

You have to set the column headins first, otherwise nothing will show. The add the list view items using a string array.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    protected override void OnLoad(EventArgs e)
    {
        base.OnLoad(e);

        listView1.View=View.Details;
        //Set Columns
        listView1.Columns.Add("Col1");
        listView1.Columns.Add("Col2");
        listView1.Columns.Add("Col3");
        //Fill Rows
        ListViewItem lvi;
        lvi=new ListViewItem(new string[] { "A", "B", "C" });
        listView1.Items.Add(lvi);
        lvi=new ListViewItem(new string[] { "D", "E", "F" });
        listView1.Items.Add(lvi);
        lvi=new ListViewItem(new string[] { "G", "H", "I" });
        listView1.Items.Add(lvi);
    }
}
