I am using the bindingNavigato r (using Windows Forms with an underlying SQL
Server table).
If I enter an invalid value in a textbox on the form (corresponding to a
column in the table) and attempt to leave the textbox, it stays in the same
textbox: I'd like to put up a message when there is a validation failure in a
text box.
How can I tell whether there is a validation failure?
Thanks.
