WPF的listview如何获取指定项的单元格

[qq37019736]

xaml的代码

<DataTemplate x:Key="isAuditeCheckDt">
            <CheckBox x:Name="isAuditeCheck" IsChecked="{Binding isCheck}" Content="{Binding isCheck}" ></CheckBox>
        </DataTemplate>

<ListView.View>
                <GridView>
                    <GridViewColumn DisplayMemberBinding="{Binding Path=userName}" Header="用户名"  
                                 Width="100"/>
                    <GridViewColumn DisplayMemberBinding="{Binding Path=type}" Header="类型"  
                                Width="150"/>
                    <GridViewColumn CellTemplate="{StaticResource isAuditeCheckDt}" Header="是否审计"  
                                Width="108"/>
                </GridView>
            </ListView.View>

我该如何获得Checkbox的单元格，我想在初始化时让前三个，或者指定的三个item的Checkbox的isenabled变成false
百度了好久找不到资料啊，找到个类似的用

 private UIElement GetListViewCellControl(int rowIndex, int cellIndex)
        {
            // rowIndex and cellIndex base is 0.
            // First Get ListViewItem
            UIElement u = listView.ItemContainerGenerator.ContainerFromIndex(rowIndex) as UIElement;
            if (u == null) return null;

            // Seartch Unit In ListViewItem 
            while ((u = (VisualTreeHelper.GetChild(u, 0) as UIElement)) != null)
            {
                if (u is GridViewRowPresenter)
                {
                    return VisualTreeHelper.GetChild(VisualTreeHelper.GetChild(u, cellIndex), 0) as UIElement;
                }
            }

            return u;
        }

这个函数，但调试了一下发现没有获取到。类似的还有

 foreach (users user in listView.Items)
            {
                ListViewItem lvi = this.listView.ItemContainerGenerator.ContainerFromItem(user) as ListViewItem;
                CheckBox cb = FindVisualChild<CheckBox>(lvi);
                cb.IsEnabled = false;
            }
 private ChildType FindVisualChild<ChildType>(DependencyObject obj) where ChildType : DependencyObject
        {
            for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++)
            {
                DependencyObject child = VisualTreeHelper.GetChild(obj, i);
                if (child != null && child is ChildType)
                {
                    return child as ChildType;
                }
                else
                {
                    ChildType childOfChildren = FindVisualChild<ChildType>(child);
                    if (childOfChildren != null)
                    {
                        return childOfChildren;
                    }
                }
            }
            return null;

        }

但是都不行啊！！！都编译通过但是获取不到checkbox啊！！！为什么，求大神解答

初始化时让前三个，或者指定的三个item的Checkbox的isenabled变成false ->根本不需要遍历什么控件方式。既然使用了Binding 就使用binding方式。 在VM中设定方式，遍历绑定的数据源，再设置一个bool变量来binding到isEnabled上根据条件设定 改变isenabled的值。

 private void isAuditeCheck_Loaded(object sender, RoutedEventArgs e)
        {
            CheckBox tb = e.OriginalSource as CheckBox;
            ContentPresenter cp = tb.TemplatedParent as ContentPresenter;
            users user = cp.Content as users;
            if (user.userName == "admin" || user.userName == "auditor" || user.userName == "security")  //如果是这三个用户不允许修改isCheck
            {
                ListViewItem lvi = this.listView.ItemContainerGenerator.ContainerFromItem(user) as ListViewItem;
                CheckBox cb = FindVisualChild<CheckBox>(lvi);
                cb.IsEnabled = false;
            }
        }

我已经会了，还是谢谢二楼
