Strange behaviour of Listview loaded from database

[David]

I have mentioned this issue previously but as yet have not found a solution.

In VB.Net 2003, I have 4 Listviews on a Tab.

Each listview has the data source property set to point to a database table
and the display member set to a field in that table.

The program runs fine and all the information appears in the listviews as
expected. If I deploy the application, the listviews still behave correctly.

But, when I close the IDE and reopen it, one particular listview keeps
clearing the data source property and I have to set it again. It only
happens with particular listview, the display member is intact but the data
source is cleared.

I am not sure if it is related but periodically 2 of the TABs on the TAB
control swap positions and I have to manually move them back in the
collections editore for the Tab control.

Any ideas ?

Thanks

David,

Can you show us the part of the code where you bind the datasource of your
listview to the database.

(I don't know a datasource property from a listview therefore I ask it)

I've noticed similar behavior and always attributed it to some qwerky
bug in VS.NET. Typically I delete the control that's acting erradically
and recreate it and this usually solves the problem.

As far as the tabs swapping places, if this continues to happen I would
put some code in your form load handler to remove all tab and re-add
them in the order you want them. It may not look right in the IDE, but
it will always be right when the program is running.

Hope this helps,
