Returns the tree node with the specified handle and assigned to the specified tree view control.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
- Type: System.IntPtr
The handle of the tree node.
When a node is added to the TreeView.Nodes collection, the TreeView control sends an NM_CUSTOMDRAW notification before the node handle is available. If you override the WndProc method of the TreeView to provide custom drawing in response to this notification, you should always check the return value of this method for a null reference (Nothing in Visual Basic) before you attempt to access the node.
The following code example gets the TreeNode that was collapsed and creates a copy of it using its Handle property. The original TreeNode is removed from the TreeNodeCollection, and the copy is added to the collection. This example requires that you have a Form with a TreeView control on it. The TreeView control should have two or more root nodes, each having at least one child node.
