c# - 如何在 WPF 中更改 Listbox 的 SelectionMode？

Question

问题很简单，我想在我的程序中更改Listbox的SelectionMode，但我发现很难解决。

Answer 1

ListBox.SelectionMode你会像这样使用System.Windows.Controls.SelectionMode Enumeration它。

//Your three options
listBox1.SelectionMode = SelectionMode.Single;
listBox1.SelectionMode = SelectionMode.Extended;
listBox1.SelectionMode = SelectionMode.Multiple;

Xaml

<Grid>
    <ListBox Height="100"  SelectionMode="Extended"  HorizontalAlignment="Left" Margin="10,10,0,0" Name="listBox1" VerticalAlignment="Top" Width="120" />
    <ListBox Height="100"  SelectionMode="Multiple"   HorizontalAlignment="Left" Margin="147,10,0,0" Name="listBox2" VerticalAlignment="Top" Width="120" />
    <ListBox Height="100"  SelectionMode="Single"   HorizontalAlignment="Left" Margin="284,10,0,0" Name="listBox3" VerticalAlignment="Top" Width="120" />
</Grid>
