Hi everyone, Is there a way to bind a control (TextBox) to an untyped
public DataSet on a WinForm and have its columns appear in the designer
under "databindings"? For example, in pseudo-code:

public DataSet myDataSet = null; // could be exposed as a property
(...)

Form_Load(...)
myDataSet = AnotherClass.GetDataSet(primaryKey);

// All databindings are set in the designer

myDataSetBindingSource.DataSource = myDataSet; // Example

I'd be willing to describe the schema in "myDataSetBindingSource" or in
a drag-and-drop DataSet, etc, but I think setting the bindings in code
isn't the way it's done- I'm not stuck on using the GUI , just want a
standard to follow. Also, when I bind to an object or typed dataset,
where the schema is already exposed, everything works great. Thanks for
any suggestions!

THe designer has to know type information at design time, so it has
to know what columns the tables in the dataset have to give you the
ability to set the textbox' binding to one of these columns. As the
dataset's columns aren't known at design time in the construction
you're working with, you won't get the info at design time and have to
setup the bindings in code.

There's nothing wrong with setting up the bindings in code however.
