Please view if ObjectDataProvider is the class you are looking for. Here is the reference: http://msdn.microsoft.com/en-us/library/system.windows.data.objectdataprovider.aspx

You would need a server side scripting language (such as PHP, Perl, JSP, ASP, Python, and many more). Once you have a language selected, the code for that should be relatively easy. The basic algorithm would be:

1. Issue an database request to get the data to fill in
2. Iterate over your results and generate a form option from each one
3. Concatenate the form options to one another
4. Insert the resulting menu into your page
