-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Visual Basic Enterprise Edition for Windows, version 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

As the user uses the ADODC MoveNext button to scroll down the visible records in
the DataGrid, the RowColChange event of the DataBound Grid fires without any
problem. But as soon as the record pointer needs to move to a row that is not
fully visible, the RowColChange event does not fire. In summary, the
RowColChange event for the DataBound Grid do not fire unless the row is
completely visible in the DataBound Grid at the instant before the ADODC
MoveNext button is clicked.

STATUS
======

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article.

Steps to Reproduce Behavior
---------------------------

1. Create a Standard EXE project in Visual Basic. Form1 is created by default.

2. Go to Project/Components and choose the Microsoft ADO DataControl 6.0
  (OLEDB), and the Microsoft DataGrid Control 6.0 OLEDB.

3. Add a DataGrid and an ADODC to the form.

4. Go to the ADODC properties and click on the ConnectString property and then
  on the ellipse.

5. Choose DSN that points to pubs in the ODBC DSN Name category and then click
  Apply.

6. Click on the Authentication tab and then put in any password needed.

7. Click on the Authentication tab and chose adcmdtable. Choose authors and
  click apply.

8. Click on the DataGrid and choose the ADODC1 on the DataSource Property.

9. Go to the RowColChange Event of the DataGrid and paste this code:

        Debug.Print "RowColChange Event Fired"

10. Run the application.

11. Start clicking on the ADODC1 MoveNext button and watch the RowColChange
  Event fire by looking at the Immediate Window. Note that the event won't
  fire once you get to a row that wasn't visible right before you clicked the
  MoveNext button.
