siteid userid username sitename

331	13	Simon	Paris 15ème
2167	13	Simon	Silac
330	13	Simon	Zonya

here is .cs code:

 private void GenerateTreeView()
    {
        OleDbConnection dbCon = new OleDbConnection("Provider=SQLOLEDB;Data Source=PC-DEV002\\SQLEXPRESS;Persist Security Info=True;Password=dcube2005*;User ID=sa;Initial Catalog=SuiviConso");
        dbCon.Open();
        OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT  su.SiteId, u.userid, u.nomUser, s.NomSite FROM   [User] AS u LEFT OUTER JOIN  Rel_Site_User AS su ON su.UserId = u.UserId LEFT OUTER JOIN Sites AS s ON s.SiteID = su.SiteId WHERE        (su.UserId = 13) ", dbCon);
        DataSet ds = new DataSet();
        adapter.Fill(ds);
        RadTreeView1.DataFieldID = "SiteId";
        RadTreeView1.DataFieldParentID = "UserId";
        RadTreeView1.DataTextField = "nomUser";
        RadTreeView1.DataValueField = "NomSite";
        RadTreeView1.DataSource = ds;
        RadTreeView1.DataBind();
        RadTreeView1.ExpandAllNodes();
    }

Here is the aspx:

 <telerik:RadTreeView ID="RadTreeView1" runat="server" Width="100%" Height="250px">
                <DataBindings>
                    <telerik:RadTreeNodeBinding Expanded="true"></telerik:RadTreeNodeBinding>
                </DataBindings>
            </telerik:RadTreeView>

So ,code is quite easy, i just don't get how to solve the problem ??

Getting and error when we tried to deploy our web application

We are getting an error when we try to deploy our web application,
Could not load file or assembly 'Telerik.Web.UI, Version=2012.2.815.40, Culture=neutral, PublicKeyToken=xxxxxxxxxxxxx'

From what I have read in some other places there is supposed to be something in the web.config that we change. BUT in our web.config we don't see anything with the Telerik.Web.UI that states a version number?

We just have these in our httpHandlers
add path="ChartImage.axd" type="Telerik.Web.UI.ChartHttpHandler" verb="*" validate="false"/>
<add path="Telerik.Web.UI.SpellCheckHandler.axd" type="Telerik.Web.UI.SpellCheckHandler" verb="*" validate="false"/>
<add path="Telerik.Web.UI.DialogHandler.aspx" type="Telerik.Web.UI.DialogHandler" verb="*" validate="false"/>
<add path="Telerik.RadUploadProgressHandler.ashx" type="Telerik.Web.UI.RadUploadProgressHandler" verb="*" validate="false"/>
<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" verb="*" validate="false"/>

And this in our <controls>
<add tagPrefix="telerik" namespace="Telerik.Web.UI" assembly="Telerik.Web.UI"/>

Where else would the version number be stated. We published and deployed our web app using Visual Studio 2012.
Another version of our web app worked and had the version 2012.2.815.40.dll in the bin. But the version we are pushing out we are using 2011.1.519.40.

So it seems we need to add the newer version of the DLL to our recently pushed project. BUT when we put the 2012.2.815.40.dll
back in the /bin folder, we get a different error saying we need to reference the 2011.1.519.40.

What is our problem? Where else, other than the web.config, would the version number be for our Telerik references????????

Thanks in advance.

System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)

I have declared the scriptManager in the Main Master page. This Master page calls a control which needs the TabStrip control on it.

When the code for instantiating radstripcontrol is added I get the following error: System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

My MasterPage code is:

<body>
    <form id="form1" runat="server">
    <telerik:RadScriptManager ID="ScriptManager1" runat="server" ScriptMode="Release"
        EnablePageMethods="True" EnableScriptCombine="False"
        EnableScriptGlobalization="True">
    </telerik:RadScriptManager>

        <cc:Navigation ID="navSite" runat="server" />
        <div>
            <asp:ContentPlaceHolder ID="cphTop" runat="server"></asp:ContentPlaceHolder>
        </div>
        <br />
    </form>
</body>

The code on the Control is:

<%@ Import Namespace="System.Xml" %>

<%@ Control Language="C#" AutoEventWireup="true"
   CodeFile="~/controls/Navigation.ascx.cs" Inherits="controls_Navigation" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<table class="nav" cellspacing="0" cellpadding="0">
<tr class="navrow"><td colspan="2">
    <table class="navrow" cellspacing="0" cellpadding="0">
    <tr id="navrow1">
    <asp:Repeater ID="repNav" runat="server">
       <ItemTemplate>
            <telerik:RadTabStrip ID="ItemDetailTabStrip" runat="server" SelectedIndex="0" MultiPageID="TabStripMultiPage"
            Skin="Outlook" BorderColor="#B3C17D" Width="958px" >
            <Tabs>
                <telerik:RadTab Text="Key Fields & Smart Terms&#153" BorderColor="#B3C17D">
                </telerik:RadTab>
                <telerik:RadTab Text="Results" BorderColor="#B3C17D">
                </telerik:RadTab>
            </Tabs>
        </telerik:RadTabStrip>
       </ItemTemplate>
    </asp:Repeater>
    <td style="width:100%; text-align:right; padding: 0px 0px 5px 0px;"
       > </td>
    </tr>
    </table>
</td></tr>
</table>

Could you please advise me what to do to overcome the persistent error?
Thanks.

Multi column filtering w/ no View state

Is view state required to perform muti-column filtering? If not, can someone point me to a decent demo of multi-column filtering with view state is disabled. The 2013 Q1 update broke all of our grids where we disabled view state for performance gains and we were able to have multi column filtering. This is a BIG step backwards if view state is required.
