Now ASP. NET2.0 will release the official version, we--ASP. NET2.0 's developers--have long been interested in it. With the introduction of the new framework, ASP. A series of new controls are built into the NET2.0. One of my favorite controls in these controls is the TreeView control. (This article was published in 2005/10/31, Microsoft ASP.)

Treeview In the past, if you wanted to use a tree control on a Web page, it would be a bit cumbersome, and sometimes even write your own code to achieve the goal of displaying the data in a tree-shaped list. In asp.net, we can easily use the Internet Exploer Web controls control provided by Microsoft to implement a tree list. In the set of Internet Exploere Web controls controls provided by Microsoft, there are Multipage,tabstrip,toolbar,

[Reference]Microsoft. web. UI. webcontrols. treeview is one of the IE webcontrol series components. A Foldable/expanded hierarchical tree directory can be displayed in the form of client scripts. This article briefly describes how to transform Treeview to meet the needs of applications in some environments, the transformation method is to add a wrapper on the periphery of the

add nodes to the TreeView control with a designer, or you can add nodes dynamically by using a programmatic approach. If the TreeView control needs to display a very good number of nodes, a one-time load can affect efficiency, in which case the PopulateOnDemand property of the TreeView control can be set to true, then the Treenodepopulate event is raised when th

. 　　 Introduction to the TreeView properties and Methods Add a TreeView control to the form to create the desired tree structure from the TreeView object's properties nodes. Example: Establish the following tree-shaped structure The HTML code in the form is: 1, autoselect= "false": When a visitor locates a n

changes, you only need to modify the XML document, and you do not need to modify the program code. (i) The node data that reads the tree control from the XML document creates a Web application project and drags a TreeView control into the page. Opens the Properties window for the control TreeView1, sets the Expandedimageurl, ImageUrl, and Selectedimageurl properties of the control's node, which specifies the picture address when the node is expan

nodes of the Treeview object. For example, create the following Tree Structure The HTML code in the form is: 1. Autoselect = "false": when a visitor locates a node in the Treeview control, the arrow on the keyboard can be used to locate the node. If the property value is "false", this operation is not allowed. 2. showplus = "true": when the two n

The Course Design of the operating system is to build a file system. I chose to use Silverlight to make the file operating system interface, because I plan to use this interface on the OJ and team websites. In the file operating system interface, the tree file structure is naturally indispensable. The first effect that this control reminds me is, of course, the dynamic loading of the file structure, without a doubt, this is a good combination of user experience and software performance.
