如何为Treeview节点自定义工具提示 [英] how to customize tooltip for treeview nodes
本文介绍了如何为Treeview节点自定义工具提示的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有树视图.如果我将鼠标悬停在子节点上，则有关该节点的描述将显示在工具提示上.
一切正常.但是工具提示没有根据页面正确定制.我将在下面粘贴源代码，
Hi,
I am having a tree view. If i keep the mouse over a child node, then the description about the node will appear on a tooltip.
everything is working fine,. But the tooltip is not customized properly acording to the page. I ll paste the source code below,
