I've gone through a few demos and walkthroughs trying to become familiar with
the new binding in vs2005. I'm having some success, but not every time.
I've create a dataset with the datasource configuration wizard. I have 3
tables in this dataset (expense, category, and type). I drag each table onto
a separate form. Visual studio creates a datagridview and binding navigator
on each form. When executed, the grids on each form populate correctly. The
problem is that one of the tables doesn't get updated when I press save, the
other two save correctly. I'm not writing any code, just using the
autogenerated code that VS writes:
Private Sub ExpenseBindingNavigatorSaveItem_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
ExpenseBindingNavigatorSaveItem.Click
Me.Validate()
Me.ExpenseBindingSource.EndEdit()
Me.ExpenseTableAdapter.Update(Me.ExpenseDataSet.expense)
End Sub
I can't figure out what is different about the expense table/grid that is
causing it to not update. There are no errors generated. If I inspect the
dataset in the debugger after I make changes in the grid, the dataset appears
to get updated. I therefore believe it has something to do with the
BindingSource or TableAdapter. The changes never make it from the dataset to
the database (an access db).
