在WPF中获取列表视图的复选框值

发布于 2024-12-21 18:56:53 字数 767 浏览 7 评论 0原文

我有这样的代码

<ListView ItemsSource="{Binding}"  Height="110.277" Margin="4,0,3,-138" Name="listView1" VerticalAlignment="Bottom">
   <ListBox.ItemTemplate>
      <DataTemplate>

        <!--<TextBlock Text="{Binding Path=Name}" Width="100" />-->
        <!--<CheckBox  IsChecked="{Binding IsSelected, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListViewItem}}}"  Width="100"/>-->
        <CheckBox Name="chk1" Content="{Binding Path=Name}" IsChecked="{Binding IsPersonChecked}" Checked="checked_accname"   Width="100" />

      </DataTemplate>
 </ListBox.ItemTemplate>

，在其中我将在按钮单击事件中从数据库动态绑定复选框的值，但我无法获取列表视图的选中复选框的值。

请帮助我解决这个问题。提前致谢

        <!--<CheckBox  IsChecked="{Binding IsSelected, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ListViewItem}}}"  Width="100"/>-->
        <CheckBox Name="chk1" Content="{Binding Path=Name}" IsChecked="{Binding IsPersonChecked}" Checked="checked_accname"   Width="100" />

不要尝试从 UI 获取检查的值。使用数据对象中的 IsPersonChecked 属性。

var persons = listView1.DataContext as Persons;
var selectedPersonsQuery = from person in persons
                           where person.IsPersonChecked
                           select person;

编辑

在了解您使用了 DataView 之后，您的查询将如下所示：

var dataView = listView1.DataContext as DataView;
var selectedPersonRowsQuery = from row in dataView
                              where row["IsPersonChecked"]
                              select row;

Do not try to get the checked value from the UI. Use the IsPersonChecked property from the data object.

var persons = listView1.DataContext as Persons;
var selectedPersonsQuery = from person in persons
                           where person.IsPersonChecked
                           select person;

EDIT

After understanding that you used a DataView your query would be something like this:

var dataView = listView1.DataContext as DataView;
var selectedPersonRowsQuery = from row in dataView
                              where row["IsPersonChecked"]
                              select row;
