Treeview与复选框？ [英] Treeview with checkboxes?

问题描述

如何使用复选框进行树视图？

解决方案

您好GClaes
这是一个小例子来说明如何添加checkBox treeView，你有一个带有按钮的treeView，点击时添加一个checkBox，这个用于添加运行时，但是如果你想添加实现时间是静态的，你可以拖动checkBoxs并放在treeView控件上

我希望这个例子可以帮助你：

Xaml代码：

   宽度= QUOT; 300"高度="480">&
;    < Grid x：Name =" LayoutRoot">
    &NBSP;&NBSP;&NBSP; < TreeView Horizo​​ntalAlignment =" Center" X：名称= QUOT; tvSampleTree"宽度= QUOT; 250"保证金=" 0,3.5,8,38.5" />    &NBSP;&NBSP;&NBSP; < Button Horizo​​ntalAlignment =" Center"余量= QUOT; 0,0,21,4.5" VerticalAlignment = QUOT;底座"宽度= QUOT; 136"高度= QUOT; 30英寸; Content =" Add New CheckBox"点击=" btnClick" />
    < / Grid>

按钮点击事件：

private void btnClick（object sender，System.Windows.RoutedEventArgs e）
    &NBSP;&NBSP;&NBSP; {
    &NBSP;&NBSP;&NBSP; &NBSP;&NBSP;&NBSP; // TODO：在这里添加事件处理程序实现。
    &NBSP;&NBSP;&NBSP; &NBSP;&NBSP;&NBSP; TreeViewItem RootLevel = new TreeViewItem（）;
    &NBSP;&NBSP;&NBSP; &NBSP;&NBSP;&NBSP; RootLevel.Header =" Root Level" ;;    &NBSP;&NBSP;&NBSP; &NBSP;&NBSP;&NBSP; //创建CheckBox子项    &NBSP;&NBSP;&NBSP; &NBSP;&NBSP;&NBSP; CheckBox FirstChild = new CheckBox（）;
    &NBSP;&NBSP;&NBSP; &NBSP;&NBSP;&NBSP; FirstChild.Content ="我是CheckBox Child" ;;

    &NBSP;&NBSP;&NBSP; &NBSP;&NBSP;&NBSP; RootLevel.Items.Add（FirstChild）;
    &NBSP;&NBSP;&NBSP; &NBSP;&NBSP;&NBSP; this.tvSampleTree.Items.Add（RootLevel）;
    &NBSP;&NBSP;&NBSP; } 1。* -----------穆罕默德·萨布里

How can I do a treeview with checkboxes?

解决方案

Hi GClaes

This is small example to show how to add checkBox in treeView,
you have a treeView with a button to add a checkBox when clicked, this for adding on runtime, but if you want to add on implementing time to be static you can drag the checkBoxs and drop on the treeView control

I hope the example to help you:

Xaml Code:

    Width="300" Height="480">

    <Grid x:Name="LayoutRoot">
        <TreeView HorizontalAlignment="Center" x:Name="tvSampleTree" Width="250" Margin="0,3.5,8,38.5"/>
        <Button HorizontalAlignment="Center" Margin="0,0,21,4.5" VerticalAlignment="Bottom" Width="136" Height="30" Content="Add New CheckBox" Click="btnClick"/>
    </Grid>




Button Click Event:

private void btnClick(object sender, System.Windows.RoutedEventArgs e)
        {
            // TODO: Add event handler implementation here.
            TreeViewItem RootLevel = new TreeViewItem();
            RootLevel.Header = "Root Level";
            //Create the CheckBox Child
            CheckBox FirstChild= new CheckBox();
            FirstChild.Content="I'm CheckBox Child";

            RootLevel.Items.Add(FirstChild);
            this.tvSampleTree.Items.Add(RootLevel);
        }
