XamDataTree运行时将节点添加到树 [英] XamDataTree add node to tree when running time

问题描述

在我的应用程序中，我使用了XamDataTree并成功地显示了节点并添加了菜单.但是我没有什么问题，当我右键单击树上显示的菜单并单击菜单时，应该在XamDataTree中添加一个节点.

我的方法就是这样

m_DataUtil是为树提供的数据.加载树时

In my application I used XamDataTree and sucessfully managed to show nodes and add menu. but I got little problem is that I when I right click on the tree a menu displayed and click on the menu should add a node to the XamDataTree .

my method is like this

m_DataUtil is Data provide for the tree. when loading tree

m_XamDataTree.ItemsSource = m_DataUtil.Data;

单击菜单时

when click the menu

m_DataUtil.AddProduct(m_product);
 m_XamDataTree.UpdateLayout();

m_product是树中显示的数据.

但是，UpdateLayout()，树未显示我想添加的节点.
互联网上没有太多有关XamDataTree的信息，并且文档不足(我认为).

任何人都可以尝试这样做并知道该怎么做?

m_product is data shown in the tree.

however the UpdateLayout() , the tree did not show the node I suppose to add.
there are not much information on the internet about XamDataTree and Documentation is not enough (I think).

could anyone tried that and know what to do ?

尝试了许多解决方案后，我发现该怎么办.看代码；

after tried many solution I find out what to do. look at the code;

m_DataUtil = null;
this.InitData();
m_XamDataTree.ItemsSource = m_DataUtil.Data;
m_XamDataTree.UpdateLayout();

将datasource类设置为null，重新加载数据并设置ItemsSource，然后更新UI.

这项工作奏效了，希望该解决方案能帮助寻求相同功能的人

set datasource class null, reload data and set ItemsSource ,then update UI.

this worked, hope this solution help someone who looking for same fucntionality
