Hi,

I have a ComboBoxTool and a TextBoxTool in a Toolbar.

My users select a value in the combo, which starts a long running process filling a grid. After this process some users use the mouse wheel without changing the focus to the grid. So they change the value in the combo again, which starts again the long running process.

Is it possible to deactivate the wheel in the ComboBoxTool?

Another idea is to set the focus by the AfterToolCloseuo event to the TextBoxTool, but this don't work. In this case I get the following message:

• 'Can't activate a root tool. Only tool instances that are in an UltraToolbar's or PopupMenuTool's Tools collection can be activated.'

Has someone an idea to solve this problem?
