wpf - ListView 所有列的宽度相等

Question

当列表视图加载到 GUI 时，我们如何为列表视图中的所有列设置相等的宽度？不在 XAML 中。

谢谢，唠叨

Answer 1

Try the SizeChanged event on the ListView.

XAML

<ListView x:Name='ListView1' 
         HorizontalAlignment='Stretch'
         Margin='12'
         VerticalAlignment='Stretch'>
  <ListView.View>
    <GridView x:Name='Gridview1'>
       <GridViewColumn Header='First' />
     <GridViewColumn Header='Second' />
       <GridViewColumn Header='Third' />
   </GridView>
</ListView.View>

C#

 public partial class MainWindow : Window
  {
    public MainWindow()
    {
      InitializeComponent();
      ListView1.SizeChanged += LV_SizeChanged;


    }

    void LV_SizeChanged(object sender, SizeChangedEventArgs e)
    {
      var newWidth = ListView1.ActualWidth / Gridview1.Columns.Count;
      foreach (var column in Gridview1.Columns)
      {
        column.Width = newWidth;
      }
    }
  }

Answer 2

您可以使用它，但它不是一个好的解决方案..

    ListView listview = new ListView();
    GridView gridview = new GridView();

    GridViewColumn gridviewcolumn1 = new GridViewColumn();
    gridviewcolumn1.Width = 10;
    GridViewColumn gridviewcolumn2 = new GridViewColumn();
    gridviewcolumn2.Width = 10;
    GridViewColumn gridviewcolumn3 = new GridViewColumn();
    gridviewcolumn3.Width = 10;


    gridview.Columns.Add(gridviewcolumn1);
    gridview.Columns.Add(gridviewcolumn2);
    gridview.Columns.Add(gridviewcolumn3);

    listview.View = gridview;
