Take a look at Control.DataBindings. This collection contains multiple
data bindings. You have to know which property of the control you're
interested in to get a specific data binding.

For example, if I bind a text box as follows:
   TextBox boundTextBox = new TextBox();
   boundTextBox.DataBindings.Add("Text", someDataSource,
someDataMember);

Then I can access that binding later on just by indexing it in the
DataBindings collection as follows:
  DataBinding textBinding = boundTextBox.DataBindings["Text"]

This is my first post and I'm no expert but I hope that helped. Let me
know if I misunderstood your question.
