Silverlight has been upgraded to 4, so it is time to learn. During this time, I sorted out the code for learning various controls and put it on my blog to keep a record for myself. It also serves as a place for beginners to communicate with each other. Note: The code is written on the basis of learning other people's code. If you are a master, do not read it, so that you do not have to worry about your time. Treeview Learning 1. Basic use of

Because it takes a long time to use recursive algorithms when using Treeview to display large-capacity database data, users are required to wait for a long time. So how can we improve the user experience when using Treeview to display large-capacity database data? This problem is well solved by the user's self-selection method. The specific method is as follows:Private void btnopendata_click (Object sender

In the work to create a TreeView for many classes, many times just because to display the field is different, you have to CTRL + C, CTRL + V to copy a nearly identical code, which is inevitably annoying, so you want to like the extension of the generic collection method, you can use the flexibility to specify which field to display. The following TreeView implements this logic: if the parent item is ticked

is parsed:Viii. Properties Panel Parameters:Template: element templates for the current tree menu;Treeitems: The element root object of the current tree menu, automatically assigned, this does not move;Verticalitemspace: The longitudinal spacing between adjacent elements;Horizontalitemspace: Horizontal spacing between different levels of elements;Itemwidth: The width of the element, if you modify the template, the value here needs to calculate the approximate width of the template;ItemHeight: T

First, thank Shi for pointing out how I can reuse the TreeView, the Microsoft IE WebControl. For more information, see http://community.111cn.net/Expert/TopicView.asp?id=3365114 IE WebControl can be used in HTML files alone or in Web form. NET programs; For the latter, the use of the program can be added to the node, can also be bound; For the latter, when binding, you can help set an XML-formatted string, or bind an XML file, as long as you assign a

treeview| data Summary:In VB6, the TreeView is often used to represent hierarchical data, but the related code that interacts with the database requires a lot of manual coding; In vb.net, because of the enhancement of the data binding function and the enhancement of language features, it is easy to bind the TreeView to the hierarchical data, this article will fir

Jquery is not described in detail here. It gives me the feeling that it encapsulates javas.The role function library. There are many useful things in it.

JS enables full selection of Treeview // Page Treeview controls such as: // Method 1: The simplest option is "Select All". If you cancel the option, no recursion is performed and no subnode is selected. function OnTreeNodeChecked1() { var ele = event.srcElement; if (ele.type == 'checkbox') { var childrenDivID = ele.id.replace('CheckBox', 'Nodes'); var div = doc

I have worked on a Windows form and need to implement the drag and drop function in the Treeview space. First, I would like to introduce the Treeview control in Windows form: using the Treeview control in Windows Forms, you can display the node hierarchy for users, just like displaying files and folders in the left pane of the Windows resource manager function of

From http://www.cnblogs.com/chenxizhang/archive/2011/06/22/2087692.html This is a function on a page in the project. We need to display a recursive tree structure through a Treeview control on the interface. That is to say, there will be many layers of nested nodes, and the layers are uncertain. This function can be easily implemented through hierarchicaldatatemplate1. Business Entity As an example, I have defined a folder type that everyone

As a common Control, the TreeView Control gives us a lot of capabilities to present hierarchical data sources. Its powerful customization and ease of use are very popular with client application developers. However, when displaying the status of the CheckBox control in front of the tree control, we sometimes need to traverse the entire tree to get the setting status of all checkpoints. Before using the sample code, we will first demonstrate the releva

After using the Treeview control of silverlight4, it is found that its binding is very weak and cannot be well integrated with the mvvm mode. Microsoft uses the control-based event design instead of the mvvm mode design. In short, Silverlight binding is very weak, at least because of silverlight4. I don't know if 5 will be improved. AndThe example of loading subitem of Treeview infinitus on the Internet is

In asp.net we know that the TreeView control can implement site navigation, using templates plus site maps as the DataSource of the TreeView to achieve easy navigation. The navigation that I want to implement is to put aside the template and the site map, and use the framework to implement the navigation dynamically. We know that the TreeView control can statica

Starting with the first contact with XML, you want to write a class that enables tree and XML to be flexibly transformed. It took almost half a day to write this class, and the time spent was a little longer. Oh.. Fortunately, a lot of harvest, proficiency in XML reading and writing classes, C # in the Foreach Loop also has a deeper understanding.

This article will introduce you to the new Code of the TreeView in javascript. If you need to know about it, you can refer to it. Example 1 The Code is as follows: Copy code Function public_GetParentByTagName (element, tagName){Var parent = element. parentNode;Var upperTagName = tagName. toUpperCase ();// If this element is not the desired tag, continue to traceWhile (parent (parent. tagName. toUpperCase ()! = UpperTagName )){

Kendo ui's treeView node Click Event modification and grid configuration summary, kendotreeview A select event can be triggered when the treeView node of kendo-ui is clicked. If you click the same node multiple times in a row, this event can be triggered only once. But it needs to be implemented: this select event is triggered every time you click the same node. This requirement is contrary to the select ev
