Changing the combobox with the mouse or the keyboard won't work. Does the MouseUp() event fire when the user use the keyboard?

I used a patch for now, I assign the current value to a property in the GetFocus() event and check if the value was changed in the LostFocus() event. It work, but the form doesn't get refreshed until the user get out of the combobox.

BTW, this combox box has multiple columns, maybe it's related in some way the the problem I have.
