Hi Som,

Without knowing the rest of your code, I would suppose the error has something to do with:

    
            (string)row["Type"]

Here's a sample that adds custome attributes to childnodes.

StackOverflow.aspx

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeFile="StackOverflow.aspx.cs" Inherits="StackOverflow" %> 
        
            <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml" > 
        
            <head runat="server">  
        
                <title>Stack Overflow</title> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server">  
        
                <asp:ScriptManager ID="ScriptManager1" runat="server" />    
        
                <div> 
        
                    <telerik:RadTreeView ID="RadTreeView1" runat="server" Height="234px" LoadingStatusPosition="BeforeNodeText">  
        
                        <Nodes> 
        
                            <telerik:RadTreeNode runat="server" ExpandMode="ClientSide" Text="Main">  
        
                                <Nodes> 
        
                                    <telerik:RadTreeNode runat="server" ExpandMode="ClientSide" Text="Sub_Item_1">  
        
                                    </telerik:RadTreeNode> 
        
                                    <telerik:RadTreeNode runat="server" ExpandMode="ClientSide" Text="Sub_Item_2">  
        
                                    </telerik:RadTreeNode> 
        
                                    <telerik:RadTreeNode runat="server" ExpandMode="ClientSide" Text="Sub_Item_3">  
        
                                    </telerik:RadTreeNode> 
        
                                    <telerik:RadTreeNode runat="server" ExpandMode="ClientSide" Text="Sub_Item_4">  
        
                                    </telerik:RadTreeNode> 
        
                                    <telerik:RadTreeNode runat="server" ExpandMode="ClientSide" Text="Sub_Item_5">  
        
                                    </telerik:RadTreeNode> 
        
                                </Nodes> 
        
                            </telerik:RadTreeNode> 
        
                        </Nodes> 
        
                        <CollapseAnimation Duration="100" Type="OutQuint" /> 
        
                        <ExpandAnimation Duration="100" Type="OutQuart" /> 
        
                    </telerik:RadTreeView> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

And the code behind:
StackOverflow.aspx.cs

    
            using System;  
        
            using System.Data;  
        
            using System.Configuration;  
        
            using System.Collections;  
        
            using System.Web;  
        
            using System.Web.Security;  
        
            using System.Web.UI;  
        
            using System.Web.UI.WebControls;  
        
            using System.Web.UI.WebControls.WebParts;  
        
            using System.Web.UI.HtmlControls;  
        
            using Telerik.Web.UI;  
        
            public partial class StackOverflow : System.Web.UI.Page  
        
            {  
        
                protected void Page_Load(object sender, EventArgs e)  
        
                {  
        
                    foreach (RadTreeNode childNode in RadTreeView1.Nodes[0].Nodes)  
        
                    {  
        
                        childNode.Attributes.Add("Category", "Category_" + childNode.Index.ToString());   
        
                    }  
        
                }  
        
            }

Hope it helps!
