WPF ListView - how to add items programmatically?
提问by JohnIdol
Even if I know it's not ideal - I need to programmatically populate a listView (for whatever reason).
即使我知道这并不理想 - 我需要以编程方式填充 listView （无论出于何种原因）。
I am declaring my columns in the markup:
我在标记中声明我的列：
<ListView.View>
<GridView>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding Path=Name}"/>
<GridViewColumn Header="Value" DisplayMemberBinding="{Binding Path=Value}"/>
</GridView>
</ListView.View>
I am adding the items like this in code (it's obviously in a loop):
我在代码中添加这样的项目（显然是在循环中）：
MyData data = getDataItem(index); //< -- whatever
ListViewItem item = new ListViewItem();
item.DataContext = data;
this.myListView.Items.Add(item);
Where MyData is defined as:
其中 MyData 定义为：
public class MyData
{
public string Name { get; set; }
public string Value { get; set; }
}
The items are being added (I can see the rows) but I don't see any content.
正在添加项目（我可以看到行）但我没有看到任何内容。
Anyone any clue?
有人有什么线索吗？
Any help appreciated!
任何帮助表示赞赏！

It works changing the code to:
它可以将代码更改为：
MyData data = getDataItem(index); //< -- whatever
this.myListView.Items.Add(data);
Now it looks obvious but ... go figure!
现在看起来很明显但是......去图！
