Hi all
I fill a datagridview manually from a dataset.
The vertical scrollbar size is full (meaning there is not much to scroll)
However there are lots of rows in the grid.
When I go down with the cursor manually (as a user) I get an error :

{"Value of '484' is not valid for 'Value'. 'Value' should be between
'minimum' and 'maximum'.
Parameter name: Value"}

when I continue (F5) the scrollbar updates and its scroll size updates to a
small square - meaning - there are a lot of rows - and I can scroll down
without errors

Please help
TIA
