Oliver:
You can most definitely create a user control and bind to it. In fact, there are several ways that you can learn more about this. You need to implement the IBusinessBindable interface to your user control. If you search the forum, you will see a ton of posts. But there are also some samples that come with the framework showing you exactly how to implement the IBusinessBindable interface on a control.
Also, you can open the source code and look at the StrataFrame textbox or any other SF web control, and you can see how the IBusinessBindable was implemented and then add this to your own control. Honestly, most times I implement IBusinessBindable myself on a new user control, I will go copy the implementation from another class and then make the changes necessary.

Hello Trent
There are some sample ? here : C:\Program Files\MicroFour\StrataFrame\CSharp Samples ? in WebForm ?
You have a solution to have a Base Class for UserControl ?
Your base class UserControl work with appbasepage ?
Thanks

Whether you are working in WinForms or WebForms, the implementation will be basically the same. I think I did mislead you a little on the previous post because you will want to use the IWebBusinessBindable on the web side of things. From your post, I assume that you are creating a custom user control, and then wanting to bind to that control. My brain was on the WinForms side of things, but here, you are wanting to do web. But the process is the same.
For example, you may want to start with a WebControl as your base class, not a UserControl like on the WinForms. It depends on what you are trying to accomplish in your application. But for example:
using System;
using System.Collections.Generic;
using System.Text;
using MicroFour.StrataFrame.UI.Web;
namespace TestingWebControl
{
public class MyCustomWebControl : System.Web.UI.WebControls.WebControl, IWebBusinessBindable
{
#region IWebBusinessBindable Members
public bool BindingEditable
{
get
{
throw new NotImplementedException();
}
set
{
throw new NotImplementedException();
}
}
public string ErrorMessage
{
get
{
throw new NotImplementedException();
}
set
{
throw new NotImplementedException();
}
}
public bool HasAdditionalBindings
{
get { throw new NotImplementedException(); }
}
public bool IgnoreManageUIReadOnlyState
{
get
{
throw new NotImplementedException();
}
set
{
throw new NotImplementedException();
}
}
public bool InError
{
get
{
throw new NotImplementedException();
}
set
{
throw new NotImplementedException();
}
}
#endregion
#region IWebBinding Members
public MicroFour.StrataFrame.UI.BindingDirections BindingDirection
{
get
{
throw new NotImplementedException();
}
set
{
throw new NotImplementedException();
}
}
public string BindingField
{
get
{
throw new NotImplementedException();
}
set
{
throw new NotImplementedException();
}
}
public string BindingFormat
{
get
{
throw new NotImplementedException();
}
set
{
throw new NotImplementedException();
}
}
public string BindingProperty
{
get
{
throw new NotImplementedException();
}
set
{
throw new NotImplementedException();
}
}
public string BusinessObjectName
{
get
{
throw new NotImplementedException();
}
set
{
throw new NotImplementedException();
}
}
#endregion
}
}
The code above is a new web control that I created and then I implemented IWebBusinessBindable. Next, you can save a lot of time by opening the SF source code and pulling the implementation code from a web control, such as a textbox. So here in the next step, I started to "flesh" this out a little by creating the private fields and start implementing the properties using the type editors, etc. that are already built and ready for you to use through StrataFrame.

You can see the highlighted changes. At this point, you just continue to pull out of the SF code until you complete the implementation of the control. Next, you will want to bind to a property that represents the data in your control. This will be the BindingProperty of the implementation. So you can change the default value to meet your needs, but after that, SF should hook up and bind for you on your custom control.
I hope that this helps.

Hello trent,
i understand your code, it's implement a custom control with the iWebBusinnessBindable,
very good for my telerik control.
But Have you a solution to get an access of my businness Object global (AppBasPage) from my WebUserControl ?
thanks
