    cannot render TreeView Web Control in IE 6.0

    Hi,

    I tried to generate a treeview that loads from the database using a connection string, but the same loads in my browser in cleartext as in the attachment,

    Please can anyone help me out how to render the control in the browser,

    I had downloaded the (iewebcontrols. msi) package & then used the TreeView control in my application.

    The code is below

    Default.aspx
    Code:
    <%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<%@ Register Assembly="Microsoft.Web.UI.WebControls, Version=1.0.2.226, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
    Namespace="Microsoft.Web.UI.WebControls" TagPrefix="iewc" %>
<!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>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;
        <iewc:TreeView ID="TreeView1" runat="server"></iewc:TreeView>
     </div>
    </form>
</body>
</html>
    Default.aspx.vb
    Code:
    Imports System.Data
Imports System.Data.SqlClient
Imports Microsoft.Web.UI.WebControls
Partial Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim strConn As String = "server=.;database=Northwind;integrated security=true;"
        Dim objConn As New SqlConnection(strConn)
        Dim objDS As New DataSet
        Dim daSuppliers As New SqlDataAdapter("SELECT CompanyName,SupplierID FROM Suppliers", objConn)
        Dim daProducts As New SqlDataAdapter("SELECT ProductName, ProductID, SupplierID FROM Products", objConn)
        daSuppliers.Fill(objDS, "dtSuppliers")
        daProducts.Fill(objDS, "dtProducts")
        objConn.Close()
        objDS.Relations.Add("SuppToProd", _
        objDS.Tables("dtSuppliers").Columns("SupplierID"), _
        objDS.Tables("dtProducts").Columns("SupplierID"))
        Dim nodeSupp, nodeProd As TreeNode
        Dim rowSupp, rowProd As DataRow
        For Each rowSupp In objDS.Tables("dtSuppliers").Rows
            nodeSupp = New TreeNode
            nodeSupp.Text = rowSupp("CompanyName")
            nodeSupp.ID = rowSupp("SupplierID")
            TreeView1.Nodes.Add(nodeSupp)
            For Each rowProd In rowSupp.GetChildRows("SuppToProd")
                nodeProd = New TreeNode
                nodeProd.Text = rowProd("ProductName")
                nodeProd.ID = rowProd("ProductID")
                nodeSupp.Nodes.Add(nodeProd)
            Next
        Next
    End Sub

End Class
    & the output in the browser only displays the database records retrieved in a straight line of text as a paragraph.(as in the attachment)
    I request you to kindl yhelp me as to why the tree view control is not at all rendering in the IE 6.0 browser.

    Regards

      Have you considered using the ASP.NET TreeView control instead?

          Thanks buddy it worked,

          But it seems strange that the Tree View Web Control gets rendered somewhat in Safari browser, but not in Internet Explorer.
          Please help me if we can rectify that control for appropriate rendering & functionality.

          But my functionality was achieved through this navigation control

          Thanks a lot
