wpftreeview多选(wpf listview多选)
wpf treeview中动态创建的treeViewItem如何用右键触发菜单？

WPF中Treeview中的节点可以做到下图的样子吗
WPF中TreeView的items一般为TreeViewItem，同时TreeViewItem自身又可以包含新的TreeViewItem，从而形成一棵子树，你想要几级节点就有几级节点了。
C#如下：
TreeView treeView = new TreeView();
//第一级，在treeView上添加
TreeViewItem treeViewItem1 = new TreeViewItem();
treeViewItem1.Header = "第一级";
treeView.Items.Add(treeViewItem1);
//第二级,在treeViewItem1上添加
TreeViewItem treeViewItem2 = new TreeViewItem();
treeViewItem2.Header = "第二级";
treeViewItem1.Items.Add(treeViewItem2);
//第三级，在treeViewItem2上添加
TreeViewItem treeViewItem3 = new TreeViewItem();
treeViewItem3.Header = "第三级";
treeViewItem2.Items.Add(treeViewItem3);
WPF的listbox有selecteditem属性可以用来做绑定那TreeView里有类似的属性可以用来绑定来获取选中的的值吗
可以定义类似如下的style
????Grid
????????Grid.Resources
????????????Style?x:Key="SelectStyle"?TargetType="TreeViewItem"
????????????????Setter?Property="IsSelected"?Value="{Binding?你的属性}"
????????????????/Setter
????????????/Style
????????/Grid.Resources
????????TreeView
????????/TreeView
????/Grid
对于wpf中的treeview控件,不了解其用法,能否给出一个:
随便写了一段，测试通过了 public Window1()
{
InitializeComponent();
ContextMenu menu = new ContextMenu();
MenuItem itemAdd = new MenuItem(); itemAdd.Header = "添加节点";
MenuItem itemDel = new MenuItem();
itemDel.Header = "删除节点";
menu.Items.Add(itemAdd);
menu.Items.Add(itemDel);
TreeView treeView = new TreeView();
TreeViewItem root = new TreeViewItem();
root.Header = "根节点";
root.ContextMenu = menu; treeView.Items.Add(root);
this.Content = treeView;
itemAdd.Click += delegate
{
if (treeView.SelectedItem != null)
{
TreeViewItem leave = new TreeViewItem();
leave.Header = "新节点";
TreeViewItem parent = treeView.SelectedItem as TreeViewItem;
parent.Items.Add(leave);
leave.ContextMenu = menu;
}
};
itemDel.Click += delegate
{
if (treeView.SelectedItem != null)
{
TreeViewItem leave = treeView.SelectedItem as TreeViewItem;
if (leave.Parent != null)
{
TreeViewItem parent = leave.Parent as TreeViewItem;
parent.Items.Remove(leave);
}
else
{
treeView.Items.Remove(leave);
}
}
};
}
WPF程序里，有一个ListView，想要在其中拖动鼠标，生成一个矩形框，并选中矩形框中的item元素，该怎么做
定义一个样式就行了~很简单。样式里面有状态和触发器，你可以为treeviewitem定义样式，设置状态过度。
