For example,

Combobox which displays names of Doctors who work in clinic, now I want to show list of doctors which are visiting doctors in same combobox instead of previous list.(plz assume labels and other things are in perfect sync to do this). For this thing I need to change column of Datasource Bound with this combobox. 

I want to achieve this by changing binding through server using data stored in database.

I hope I am making it little more clear about my scenario.

Once the value in DataBase is changed by developer or database admin, the binding of that control should get changed and display the changed value.

Like Patient Name will always display Patient Name but source from where that values comes can change.

I am designing a Client-Server Application where client will have Silverlight app running and hence i want to have complete control over binding and values to be displayed this will enable me to make small small changes quite easily. Its a feature i want to add to my project to make it different from other students but seems its bit difficult.

Can you suggest some way to solve my problem?

user will see data set by server.

No binding in xaml and no binding in Cs either, server will decide binding and server will set the data using binding.

I have a control-mapping feature, which maps and stores control and its related datasource in database table.

eg. TextBox: txtPatientName will be mapped with PatientName property of datasource and this data will be stored in database.

Thanks for your reply.

Yes its kind of strict requirement, because the properties which will be bound with Controls sometimes come from DataBase, As being a developer I know those properties before hand but the way my project is supposed to work, client side (XAML Page) should not have any kind of binding set, all the bindings should be set from Server side not even from .cs file.

I have tried using Binding object, Loaded Event and few more.

I have also tried to obtain the TextBlock using LoadContent() function but still somehow binding doesn't take place.

I hope I made myself clear for your understanding. If you want some more details please let me know.

Thanks  

But I want to bind the Textblock in code and not in XAML. That is the requirement. 

using DataTemplate is not mandatory for me, but since I am quite new to Silverlight don't know other option to be used.

Can you suggests somethings, may be a hint or idea.
