I would like to create a Treepanel, which is updated once a second. So I took a store with a proxy for data acquistion:
If I write: rootNode.expand() I can only get access to the children nodes of this rootNode, but can\'t get access to the grandchildre开发者_开发百科n nodes of this rootNode. I have to write:
I\'ve an Async TreePanel that uses an RPC proxy to load data from server. I want to reload a node by using:
I have defined a class which represents a tree structure GeographicalUnits = Ext.extend(Ext.tree.TreePanel, {
I would like a \'reset\' method to uncheck all the check开发者_Go百科ed nodes in Ext.tree.TreePanel.tree.getRootNode().cascade(function(n) {
Lets say I have a Ext.tree.TreePanel object, and it has data loaded from an external file, ex: var tree = new Ext.tree.TreePanel({
Does anybody know how to enable drag and drop onto leaf nodes of 开发者_StackOverflowa treepanel? My scenario is exactly like this one: http://dev.sencha.com/deploy/dev/examples/tree/reorder.html
When a node is dropped it goes to beforenodedrop event in TreePanel But what happens when node is invalid ? i开发者_StackOverflow中文版t doesn\'t drop and so beforenodedrop event is not notified
I need to put some of the entities created via a.dbml Linq-To-Sql file into Session State. Because Iam using out-of-proc State Server, they need to be serializable开发者_如何学编程.
