解决方案

您需要创建一个继承自TreeView的自定义树视图。

您还需要创建一个自定义树视图节点继承自TreeNode的类。

 公共 类 TreeViewTest 
 继承 TreeView 
 
 公开 重载 属性节点（） As  List（ Of  TreeViewNode）
 
 结束  Class  
 
 公共 < span class =code-keyword>类 TreeViewNode 
 继承 TreeNode 
 私有 m_iMyCustomNodeProperty 作为 整数 
 
  Public   Property  MyCustomNodeProperty  As   Integer  
 获取 
 返回 m_iMyCustomNodeProperty 
 结束 获取 
 设置（值作为 整数）
 m_iMyCustomNodeProperty = value 
 结束 设置 
  E nd  属性 
 结束 类 

一旦你的自定义树视图类完成，你就可以这样使用它。

  Dim  oMyCustomTree  As  新 TreeViewTest 
 oMyCustomTree.Nodes（ 0 ）。MyCustomNodeProperty =  1  

是的。

 Node.Attributes.Add（SomeDate，11）

I want to have Tree Nodes containing some customized Properties to store some data into it is it possible please explain with vb.net code for windows form.

Thanks and regards

You will need to create a custom treeview that inherits from TreeView.
You will also need to create a custom treeview node class that inherits from TreeNode.

Public Class TreeViewTest
    Inherits TreeView

    Public Overloads Property Nodes() As List(Of TreeViewNode)

End Class

Public Class TreeViewNode
    Inherits TreeNode
    Private m_iMyCustomNodeProperty As Integer

    Public Property MyCustomNodeProperty As Integer
        Get
            Return m_iMyCustomNodeProperty
        End Get
        Set(value As Integer)
            m_iMyCustomNodeProperty = value
        End Set
    End Property
End Class

Once your custom treeview class is complete you can use it in this manner.

Dim oMyCustomTree As New TreeViewTest
oMyCustomTree.Nodes(0).MyCustomNodeProperty = 1

Yea.

Node.Attributes.Add("SomeDate", "11")
