ListView列的MinWidth

Question

如何为WPF中的Listview列指定MinWidth？

Answer 1

此代码使用Thumb控件。它将阻止用户仅以指定的宽度拖动标题。

在WPF中添加此内容

<ListView x:Name="MyListView"
          IsSynchronizedWithCurrentItem="True" 
          ItemsSource="{Binding Path=Items,  
                                Mode=Default, 
                                Source={StaticResource DataProvider}}"
          Thumb.DragDelta="Thumb_DragDelta">

在C＃中做

public Window1() 
{  
  InitializeComponent();  
  MyListView.AddHandler(Thumb.DragDeltaEvent,new DragDeltaEventHandler(Thumb_DragDelta),true);
}
void Thumb_DragDelta(object sender, DragDeltaEventArgs e)
{ 
  Thumb senderAsThumb = e.OriginalSource as Thumb;  
  GridViewColumnHeader header = senderAsThumb.TemplatedParent as GridViewColumnHeader; 
  if (header.Column.ActualWidth < MIN_WIDTH)     
    header.Column.Width = MIN_WIDTH;   
  if (header.Column.ActualWidth > MAX_WIDTH)
    header.Column.Width = MAX_WIDTH;
}
