Getting only when the user cancel the selection in a combo box...

Hi,

It's a way to know when the user has cancelled the selection of new item in a combo box( drop down shown, and then click not on the drop down box).

I have tried to overwrite OnSelEndCancel, but works too when the focus is in other place, and is called TWO TIMES !, and I want to change the current selected in that method and delete one item ( that's why I have overwritten it), but then call OnSelEndOk too !

What can I do ?, Thanks, Bye !
