I have a form with datagridview. I populate my datagrid with my dataset data.
Everything is going fine.
The only issue i found is.
if i lock the system and leave the form with datagridview containing data it it, and after some time (say 10 mins, when monitors goes to standby mode) if i unlock the system i see that the datagrid is empty. but a window with label has no effect its intact.
It appears my connection to the db is correct when I select different options the datagrid displays the correct number of records. So I am not sure why I can not see the data in the grid.[code]....

I have a few forms that the user uses to select data records and then perform some analysis on them.So the selected records are presented in a datagrid and each in turn it reviewed and the analysis data added to the extra columns, works very.
