I have a situtation where I need to not let the mouse roller change a value in a drop down list. I was able to accomplish this by trapping the 'MouseRoller' event and canceling it for a ComboBox. However, now my users want the mouse roller to be enabled if the list is displayed for a ComboBox so they can scroll through the items.

So I was wondering if there is a way to know if the list is being displayed for a ComboBox editor? I am hoping to use it in the 'MouseRoller' event and not cancel the event if the list is in fact being displayed.

Thanks in advance.

I think you are looking for combo.droppedown ?

Hope that is what you are looking for.

Thanks for the reply...Yes, logically that is what I am looking for, but there is no such property 'droppedown' for combo that can give me what I am looking for...Am I missing something?

I am using VS 05 are you?

ComboBox cb = new ComboBox();

if(cb.DroppedDown)

thanks

I am sorry, I must specified earlier, I am using UltraComboBoxEditor from Infragistics...

Thanks.

Thanks for the link!
