BindingSource And ComboBox: Combobox Binded on another Source

I would like to make Something in my form. I have a Binding source binded on Linq to Sql Class. The class 开发者_Python百科Workorder contains one field Site. I would like to display The combobox with all the site, but selected on the site form my workorder.

I'm clear?

I found the way through the Databindings component that allow to add more than one source to the TextBox.
