It turned out to have a special post in the forum, but because some questions can't be found because of the posts, some problems have been found, and this time they have added some, they are sent to the document area for easy inquiry.

1. Download the address http://msdn.microsoft.com/downloads/samples/internet/DOT_NET_SERVERCONTERNTROLS/WebControls/default.asp Download is the versions of the suffix BAT (1) Bulid. Point Bulid.Bat Ports CSC.exe The path generates Microsoft.Web.ui.WebControls.dll. (2) Creating a empty directory WebCtrl_client / 1_0 under wwwroot. (3) Copy the file under Build / Runtime to WebCtrl_Client / 1_0. (4) Select the custom toolbox for the toolbox, add Microsoft.Web.ui.WebControls.dll. Some trouble but if you can find the suffix is ​​the automatic installation version of MSI, directly next step (I have always used this version, hoho), by "Custom Toolbox" -> ". Net Framework Components" Add TreeView to Toolbox

2. Unable to display the version of TreeView when running, it is best to download the English version of the automatic installation version to reinstall, before installing, you should first go to add the delete program to remove the original version

3. Display format error (non-tree display) TreeView requires client browser version to IE5.5 and above, it is best to request client upgrade to IE6.0

4. Use TreeView in the framework to set the NaviGateURL, Target property, update additional Frame

5. Can't find the TREENODE class using TreeView, it is best to add Namespace: use Microsoft.Web.ui.WebControls;

6. TreeView node traversal (recursive algorithm) private void Page_Load (object sender, System.EventArgs e) {GetAllNodeText (TreeView1.Nodes);} void GetAllNodeText (TreeNodeCollection tnc) {foreach (TreeNode node in tnc) {if (node.Nodes .Count! = 0) getAllNodeText (Node.Nodes); Response.Write (Node.Text ");}}

7. Get the parent of the Node Node Treenode PNode; if (node.parent is treenode) pnode = (Treenode) node.parent; else // node is root node

8. Modify TreeView pattern (example) With code: TreeView1.defaultStyle [" font-size "] =" 20pt ";

9. When expanded, change the autopostback when it is changed when changing the selection node; add / n" " / n" ""; Page.RegisterClientScriptBlock ("inittree", strscript); then submit only when you click on the node change! 10.TreeView combines XML to set the XML file to the following format, then set the TreenODesRC to the XML file to set the XML file or with code TreeView1. Treenodesrc = "a.xml"; treeView1.databind ();

Client Control TreeViewHttp: //expert.9cbs.net/expert/topic/1382/1382892.xml1. Set the selected node, such as selecting the second node function setselnode () {TreeView1.selectedNodeIndex = "1";}

2. Get the text, id or nodedataFunction getttribute () {Alert (TreeView1.SelectedNode ("text")));} Replace Text is ID or NodeData, you can get the selected node ID or NodeData

3. Modify the node properties, such as modifying the textFunction modify () {var node = treeview1.gettreenode ("TEXT"); "Text", "Hgknight");}

4. Get clicking node function treeview1.onclick () {alert (TreeView1.clickedNodeIde ";});

5. Add Node Function AddNode () {var node = TreeView1.createtReenode (); Node.setttribute ("text", "hgknight"); treeview1.add (node);}

6.JS Traversing All Nodes VAR AllRootnode = New Array (); allrootnode = treeview1.getchildren (); alertnode (allrootnode);

Function alertNode (nodeArray) {if (ParseArray.Length) == 0) Return; else {for (i = 0; i
