ComboFilter attachEvent


is there a way to attach an event to a combo_filter in an grid header?
My client wants the text in the filter cleared or selected (so the curent text is replaced as soon as typing starts) as soon as they click the combofilter and the list opens.

There are 5 headers and the combo_filter is in the 4th column of the 4th header.

kind regards,
