如何从列表框中获取所选项目在 WPF 中有复选框? [英] How to get selected items from listbox has checkboxes in WPF?

问题描述

这是列表框代码:

<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# 获取上述 ListBox 中所有选中的复选框?

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

推荐答案

最好将 CheckBox 绑定到 ListBoxItem 的 IsSelected 属性，像这样:

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/选中的项目.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.
