Preselect cascading DesktopListBoxes

Good afternoon (o;

Have a window with four DesktopListBoxes where a user chooses from left to right what device he wants to use:

After selecting through, all IDs from the ListBoxes are stored in a property.

Now when the user wants to open it again and the device property is set (manufacturer, series, package, chip) what is the best way to preselect them?

I use now the Opening event for each DesktopListBox, which for the left most is fine. The next one depends on the previous one. But I assume I can’t be sure that the previous one is already drawn and has run the Opening event through.

Can I somehow use the CellPressed event via RaiseEvent to accomplish this?

You could use the Window’s Opening event, which is assured to occur after the Open events of every control on the Window and the controls are ready to access.

Ah that is prefect and makes it much simpler then (o;
