Hi to all,

I'd like to ask one question about Telerik control in DotNetNuke 6.0.

I'm using DotNetNuke Community Edition 06.00.01 (310)

I'd like to use Telerik control in my own module developed, for develop the module I’ve used template from page:

http://christoctemplate.codeplex.com/

From documentation:
http://www.dotnetnuke.com/Resources/Blogs/EntryId/3114/Telerik-Controls-in-DotNetNuke-6-0.aspx

I read:
Every control included in Telerik's 2011 Q1 SP2 release has a wrapper in 6.0.0.

I'd kindly like to ask what does it mean.

For example when I'd like to use one control in my project I can use following:

<%@ Register Assembly="DotNetNuke.Web" Namespace="DotNetNuke.Web.UI.WebControls" TagPrefix="DNNCtrl" %>

<DNNCtrl:DnnComboBox ID="DnnComboBox1" Runat="server" Sort="Ascending"
                                    Text="Select" AppendDataBoundItems="True">
 </DNNCtrl:DnnComboBox>

Protected WithEvents DnnComboBox1 As Global.DotNetNuke.Web.UI.WebControls.DnnComboBox

When I want to access to properties exposed by DnnComboBox1 I can use following code:

DnnComboBox1.AddItem("test",1)

If I try to download Telerik's 2011 Q1 SP2 and import a Telerik control in a new Asp.NET web project ( no DNN ) and try to repeat all the process, I can access to other properties for example:

RadComboBox1.Items

If now I try to write this line in DDN project that include Telerik control, I get following error:

Error    13    'Public ReadOnly Property Items As Telerik.Web.UI.RadComboBoxItemCollection' is declared in project 'Telerik.Web.UI.dll', which is not referenced by project . Add a reference to 'Telerik.Web.UI.dll' to your project

Now if I add this reference I can access to Item property.

I'd kindly like if this behavior is part of wrapper class written to access Telerik control from DNN.
For my knowledge, I'd kindly like to ask why is necessary to use wrapper class for access to Telerik control from DNN.
