I want to display the tooltip on drop-down list of a combobox using ctooltipctrl.

With ctooltipctrl I can able to display the tooltip for individual controls on a dialogu, but for ccombobox it is not working.

Could you please help me to resolve this issue.

What I have tried:

I have created combo class and list box class. In combo class I'm getting the listbox handle and calling the presubclasswindow of a listbox class using the listbox handle value.

In the presubclasswindow I have enabled the tooltips using enabletooltips (true). Created ontoolhittest to get the item row and handled tnn_needtext message is to get the tooltip text.

During runtime the ontoolhittest is getting called and row details are being fetched but the tnn_needtext is never been called.i have overide a function for tnn_needtext..how to get this notification workto display the tooltip
