Bound TextBox Value Not Saved 1

If I change the value in a bound textbox on an MDI child form, then click the save button on the toolbar without leaving the textbox, the value in the textbox reverts to the old one. I have stepped through the code in debug, and the program is changing the new text value back to the old one at the point I do an EndCurrentEdit on the BindingManagerBase. The new value is never making it into the DataSet. If I tab out of the textbox before clicking save, the new value is saved as expected. Is there a way to save the new value using the toolbar without leaving the textbox first?

Thanks.
