TreeView menu navigation and permission usage for common Winform development controls, winformtreeview TreeView is a great control. We often get stuck in WEB development. Of course, here we will introduce the usage of ghost in winform. First, let's introduce several attributes.

Generally, by specifying an ImageList control, you can place all the node charts to be filled in the control and direct the ImageList attribute of the Treeview to it, then, you can specify the corresponding icon se

Generate a TreeView tree structure based on the data table content. The common practice is to start from the top level, and then generate one by one recursive query traversal. This method is easy to implement and easy to think of, but it is inefficient because of Database Retrieval (SQL statements need to be interpreted and executed, and database files are operated) it is time-consuming, especially when there are many layers and nodes in the tree.

In WPF/Silverlight development, we recommend using mvvm mode for development to facilitate separation of business and UI and unit testing. However, the processing of Treeview in Silverlight involves operations related to treeviewitem. If mvvm is used for implementation, it is still not that easy.
