Hi guys, In all samples of TreePanel in the source code the part in which we create listeners is in html code, but How to do this in code??? Because my tree panel is created dinamically. The part of html code that I need in c# code is in a big letter. <ext:TreePanel ID="TreePanel1" runat="server" Title="Tree" AutoHeight="true" Border="false"> <Root> <ext:AsyncTreeNode NodeID="0" Text="Root" /> </Root> <Listeners> <BeforeLoad Fn="nodeLoad" /> </Listeners> </ext:TreePanel> Please help me.

Hi Mickna, Example this.TreePanel1.Listeners.BeforeLoad.Fn = "nodeLoad"; Hope this helps. -- Geoffrey McGill Coolite Inc. Development Team Skype : geoffrey.mcgill Forum Guidelines \| Coolite Examples \| Coolite API Docs \| ExtJS API Docs \| Twitter Permalink: Post #23953

Yes, I know but if I need to have the nodeLoad method that receives another parameter for example: [AjaxMethod] public string NodeLoad(string nodeID Coolite.Ext.Web.AsyncTreeNode node) { /*****Code*******/ } How can I do that by code???? Mickna. Permalink: Post #24113

I need the node because inside the NodeLoad method I need information of the node. Mickna. Permalink: Post #24118

Hi, Then pass required information as additional arguments. Javascript TreeNode object is very comples (for example, contains reference on parent tree) and can't be automatic serialized (even if it is possible then why is required to pass such huge information to server). Use simple objects 1. Coolite.AjaxEvents.MyMethod(Ext.encode({Id: node.id, Text: node.text})) 2. public class SimpleNode{ public string Id{...} public string Text {...}} 3. AjaxMethod: public void MyMethod(SimpleNode node){... -- Vladimir Shcheglov Coolite Inc.

This is how I load my treenodes as well, and it works great, but I have a question. Is it possible to page the results when using this method, and how would you go about doing that? Permalink: Post #24947
