当我们尝试在运行时更改Extended TreeNode的ForeColor属性时，它会将ForeColor属性设置为指定的值，但在树节点的视觉外观中没有显示。

嗨特里，

.NET TreeView control does not supports tristate check box and hence we have extended the TreeView functionality and created Extentended treeview and tree node. But when we extend treenode then ForeColor and BackColor properties of treenode are not functioning; however, other properties seems to be working as expected.

It seems that when we try to change the ForeColor property for Extended TreeNode at runtime then it sets the ForeColor Property to specified value but the same is not shown in visual appearance of tree node.

Codes for Extended TreeView and extended TreeNode were Reffered from article "Tri-State TreeView Control for .Net 1.1"
on CodeProject at URL : http://www.codeproject.com/KB/tree/treeviewex2003.aspx

Can anyone help me to sort out this problem or suggests something that I can used to achieve the Treeview with TriState checkbox without breaking any other characteristics of treeview control.
