Yes.
But you would need to bind to something that has the types.
You could build a datatable programmatically with all the right field types
and set the length of text columns etc
Then bind to that.
If you put a letter in a numeric column it'll throw an error for you.
Not a terribly user friendly error but there may be a way to over-ride it.
While since I did winforms.

Thanks. I guess I will attempt to do it manually then.
