The TreeView is a great control, and we are often sleepy when doing web development. Of course, here is the introduction of WinForm inside the usage of chatter.First introduce a few properties, checkboxes set to True if the tree node will appear in front of the CheckBox check box, ImageList binding tree inside the icon (the interface is placed on a imgelist control, binding on it), Showlines (show lines when tree expands), etc.Oh, this method is good,

However, in the management of the UI elements, the circular Linked List reference between the script class object and the DOM object is used, so some cleanup work must be done when the page exits, that is, a dispose method is implemented for each class. Our Treeview
ComboBox with the Treeview drop-down control Yes, as the title says, it is a Treeview in the drop-down box, but why do we need such controls?

The general view is similar to the tree structure and the list structure. A friend in the self-created group (2175832) asked me how to drag the listview item to the Treeview and generate a subnode. It is troublesome to sign for it. I have a hard answer. Use the b
The Treeview control is often used in winform development. For example, we often use it for Layer Control when developing GIS.
