Question

我正在使用列表框，当你单击它上面的项目时，你会看到列表框的值上标有蓝线，我想禁用它，你不能标记列表框的值和复制粘贴它

我尝试使用IsSelected =“False”但没有成功......

<ListBox x:Name="seus" IsSelected="False"  Height="115" Width="150" ItemsSource="{Binding Use}" SelectionChanged="listbox_SelectionChanged" AllowDrop="True" PreviewDrop="ListBox_PreviewDrop" />

这是列表框的事件

private void listbox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (sender is ListBox)
    {
        var listBox = sender as ListBox;
        if (e.AddedItems.Count == 1)
        {
            if (listBox.SelectedItem != null)
            {
                var mySelectedItem = listBox.SelectedItem as User;
                if (mySelectedItem != null)
                {
                    DragDrop.DoDragDrop(listBox, mySelectedItem.Name, DragDropEffects.Copy | DragDropEffects.Move);
                }
            }
        }
    }
    else
        return;
}

关闭选择确实有点棘手。但是添加一个ItemContainerStyle就可以了：

<ListBox.ItemContainerStyle>
    <Style TargetType="ListBoxItem">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListBoxItem">
                    <Border>
                        <TextBlock HorizontalAlignment="Stretch" Text="{Binding}" />
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ListBox.ItemContainerStyle>

我知道这只是一半。它不会关闭复制/粘贴。

禁用D＆amp; D中的列表框选择
