Question

这是我的问题，我有一个带复选框的列表视图，我想得到所选行的索引我想得到行的索引以在验证后禁用此行

我尝试不同的方法

CheckBox cbx = sender as CheckBox.tag;
    if (cbx != null) {
        var index = cbx.Tag.ToString();
    }
(((ContentPresenter)((CheckBox)sender).TemplatedParent)).IsEnabled = false; with this i disable just the checkbox 

CheckBox cbx = sender as CheckBox.tag;
int index = (int)(sender as CheckBox).Tag;

Answer 1

使用以下代码：

int index = YourListView.SelectedIndex;

Answer 2

尝试以下示例代码。添加如下属性

public int Selected
        {
            get { return _selected; }

            set
            {
                _selected = value;

                OnPropertyChanged(new PropertyChangedEventArgs("Selected"));
            }
        }

        public void OnPropertyChanged(PropertyChangedEventArgs e)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, e);
            }
        }

将 INotifyPropertyChanged 继承到您的cs文件中以获取 OnPropertyChanged

在视图中绑定listview

中的上述属性

<Grid>
            <ListView Margin="10" Name="lvUsers" SelectedIndex="{Binding Selected}">
                <ListView.View>
                    <GridView>
                        <GridViewColumn>
                            <GridViewColumn.CellTemplate>
                                <DataTemplate>
                                    <CheckBox Tag="{Binding ID}"  IsChecked="{Binding RelativeSource={RelativeSource AncestorType={x:Type ListViewItem}}, Path=IsSelected}"/>
                                </DataTemplate>
                            </GridViewColumn.CellTemplate>
                        </GridViewColumn>
                        <GridViewColumn Header="Name" Width="120" DisplayMemberBinding="{Binding Name}" />
                        <GridViewColumn Header="Age" Width="50" DisplayMemberBinding="{Binding Age}" />
                        <GridViewColumn Header="Mail" Width="150" DisplayMemberBinding="{Binding Mail}" />
                    </GridView>
                </ListView.View>
            </ListView>
        </Grid>

尝试使用此属性检查复选框是否已禁用。我希望这对你有用。
