Hi,
Please look at the example.
Example
<%@ Page Language="C#" %>
<%@ Import Namespace="TreeNode=Ext.Net.TreeNode" %>
<%@ Import Namespace="TreeNodeCollection=Ext.Net.TreeNodeCollection" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!X.IsAjaxRequest)
{
this.BuildTree(this.TreePanel1.Root);
}
}
private TreeNodeCollection BuildTree(TreeNodeCollection nodes)
{
if (nodes == null)
{
nodes = new TreeNodeCollection();
}
TreeNode root = new TreeNode();
root.Text = "Root";
nodes.Add(root);
bool submit = true;
for (int i = 0; i < 10; i++)
{
TreeNode node = new TreeNode();
node.NodeID = (i + 1).ToString();
node.Text = "Node" + (i + 1);
node.CustomAttributes.Add(new ConfigItem("submit", JSON.Serialize(submit), ParameterMode.Raw));
root.Nodes.Add(node);
submit = !submit;
}
return nodes;
}
protected void SubmitNodes(object sender, SubmitEventArgs e)
{
X.Msg.Alert("Submit", "You have submitted " + e.RootNode.Children.Count + " nodes").Show();
