如何从列表框中选择项目在WPF中有复选框？ [英] How to get selected items from listbox has checkboxes in WPF?

问题描述

这是ListBox代码：

This is the ListBox code:

<ListBox x:Name="courseslistview" 
         ItemsSource="{Binding .}" 
         FontSize="18.667" 
         FontFamily="Trebuchet MS" 
         LayoutUpdated="courseslistview_LayoutUpdated">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <CheckBox Content="{Binding .}" />
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

如何使用C＃获取上面ListBox中的所有复选框？

How can I use C# to get all the checked checkboxes in the above ListBox?

推荐答案

最好将复选框绑定到是 ListBoxItem 的属性，如下所示：

It would probably be best to bind the CheckBox to the IsSelected property of the ListBoxItem, like so:

<DataTemplate>
    <CheckBox Content="{Binding .}" IsChecked="{Binding RelativeSource={RelativeSource AncestorType={x:Type ListBoxItem}}, Path=IsSelected}" />
</DataTemplate>

然后，您可以从ListBox.SelectedItems集合中获取选中/您还必须设置 SelectionMode 到多个。

Then you can get the checked/selected items from the ListBox.SelectedItems collection. You'd also have to set SelectionMode to Multiple.
