If you want data to be changed whenever a combobox is changed then you
will have to opt in for onChangeCommitted event handler of the combobox.

If this combo is part of Grid and you want Grid 2 to change with every
change in this combobox then I will suggest that you have a look at the
mastersource property of query.

Any navigation in Grid 1 will automatically result in fresh data in Grid 2

I did start using mastersource as a property in Grid but that project
never took off so do not remember much details.

If required will develop a sample test form.
