thanks so much x77. My save method gets called from several places including other forms, so I just used your:
MyBindingSource.EndEdit()
and that appears to have solved the problem

Question
How do I commit changes in a databound textbox in vb 2008?
I am using vb 2008 and LINQ to SQL to create a windows forms application that connects to a SQL database. On my form, I have several data-bound text boxes via a binding control that connect to my database via LINQ to SQL classes. My issue is that if a user is editing a text box and then clicks my save button, which commits the changes to the database by calling the submitchanges method on the datacontext, the changes the user made in that text box are not applied. If the user clicks out of the textbox first, and then invokes the save, everything works fine.
Thanks in advance for any ideas.

1 - Verify properties of Save Button - CausesValidation = true
This ensure that all binded textboxes are validated before the buton.click event fired.
Do'nt use MouseDown/Up of Save Button as action to commit the changes.
2 - Also you can force the validation and force EndEdit
SaveButton_Click(....
If ValidateChildren() = False Then Return 'No save unvalidated data.
try
MyBindingSource.EndEdit() ' if you have BindingSource
PropMgr.EndCurrentEdit() ' if you have PropertyManager
Catch ex As Exception
MessageBox.Show(ex.Message
Return False
End Try
Note, this only is valid if validation throw exceptions or you use the e.Cancel = true on validation events.
You also can use the EndEdit of BindingSource / PropertyManager.
To Get the PropertyManager On FormLoad you can write..
Private WithEvents PropMgr As PropertyManager
Sub Form_load....
PropMgr = DirectCast(BindingContext(
