[英]Missing ListView.Columns in WPF
I'm writing an application with a ListView in C# WPF. 我正在使用C#WPF中的ListView编写应用程序。 I was wondering if I was missing a reference of something, because I get this error all the time: 我想知道我是否错过了某个东西的引用,因为我总是得到这个错误:
'System.Windows.Controls.ListView' does not contain a definition for 'Columns' and no extension method 'Columns' accepting a first argument of type 'System.Windows.Controls.ListView' could be found (are you missing a using directive or an assembly reference?)` 'System.Windows.Controls.ListView'不包含'Columns'的定义,也没有扩展方法'Columns'接受类型为'System.Windows.Controls.ListView'的第一个参数'(你是否缺少using指令)或汇编参考?)`
It's not only with MyListview.Colums but also when I want to add a multi-column item to my ListView, for example by following this . 这不仅与MyListview.Colums而且当我想通过下面的多列项添加到我的ListView,例如这个 。 MyListView.Items.Add("Column1Text").SubItems.AddRange(row1);
This gives me the same error for SubItems 这给SubItems带来了同样的错误
It's hard for me to explain, so if something isn't clear you can ask. 我很难解释,所以如果不清楚你可以问。
Edit: With a lot of help from you and some Googling skills I found a solution. 编辑:在你的帮助和一些谷歌搜索技能的帮助下,我找到了解决方案。 My XAML code: 我的XAML代码:
<Grid>
<ListView x:Name="MyListView"
<ListView.View>
<GridView x:Name="MyGridView">
<GridViewColumn Header="#" DisplayMemberBinding="{Binding Number}" Width="24" />
<GridViewColumn Header="Song" DisplayMemberBinding="{Binding Song}" Width="390" />
</GridView>
</ListView.View>
</ListView>
and here is how to add an item: 以下是添加项目的方法:
MyListView.Items.Add(new { Number = 1, Song = "My first song" });
MyListView.Items.Add(new { Number = 2, Song = "My second song" });
This was my first time working with bindings, but I learned a lot! 这是我第一次使用绑定,但我学到了很多东西!
