How to Get-Set Values to and from a Child Widget - Sitefinity - Front- & Back-End Development

Hi All, need some help with this scenario,

We created some widgets and everything was fine until bump into
the scenario where Widget "A" contains Widget "B"...
In run time (specifically in the ItemDataBound event) need to set some values to the Widget "B" Instance.

01.<asp:ListView ID="lvMostViewedItems" runat="server" DataSourceID="cdsMostViewedItems" >

02.<ItemTemplate>

03.<ul>

04.<li>

05. <div class="scItemOption">

06. <scweb:ItemOptions ID="wucItemOption1" runat="server" />

07. </div>

08. </li>

09. </ul>

10.</ItemTemplate>

11.</asp:ListView>

In Code Behind the Code looks as follow:

1.void PagedControl_ItemDataBound(object sender, ListViewItemEventArgs e)

2.

3. ItemOptions wucItemOptions = e.Item.FindControl("wucItemOption1") as ItemOptions;

4. wucItemOptions.ItemNumber = Convert.ToDecimal(lblitemNo.Text);

5. wucItemOptions.SmallAddToCartOption = true;

6.

The code finds the wucItemOptions widget but internally the Widget "B" Container fails to set any value.

01.System.InvalidOperationException was unhandled by user code

02. Message=Invalid PathDefinition.

Basically can a Custom Control contain a Custom Control ?

Need to do something different to register the second control ?
What I'm missing here... Virtual Paths maybe ?

In the Visual Studio Designer If I drop one of my custom control on another I receive the following error..

Error Rendering Control - Logout1An unhandled exception has occurred.

Resolution of the dependency failed, type = "Telerik.Sitefinity.Configuration.ConfigManager", name = "XmlConfigProvider". Exception occurred while: Calling constructor Telerik.Sitefinity.Configuration.ConfigManager(System.String providerName). Exception is: ArgumentNullException - Value cannot be null

. Parameter name: path1 ----------------------------------------------- At the time of the exception, the container was: Resolving Telerik.Sitefinity.Configuration.ConfigManager,XmlConfigProvider Calling constructor Telerik.Sitefinity.Configuration.ConfigManager(System.String providerName)

Can someone point me in the right direction.. Please..

Ok forget about the VS error because anyway I found that "Templated ASP.NET user controls are not supported in the Visual Studio designer."...

But they should work in run time.. and my SimpleView Controls fails to properly set or get info from child SimpleView controls.
