>>What is the best way of implementing a Click and a DblClick in a Combobox.

What I'm trying to do here is this.

All my Foreign Key columns are based on a Drop-down List (Style = 2).

When the user clicks (single) the List opens up as usual (that's fine)

When they right click its parent.parent.rightclick is called "this.parent.parent.rightclick()" which opens up a shortcut menu with the usual add/delete/navigation menu options etc. this happens only if that combo's parent is a column (i.e. it belongs to a grid)

What I want to do now is this. If they double click such a combo (i.e. it belongs to a grid) I want to open that Foreign Keys data entry form so that they can add/delete records in that table. Right now Ctrl+Ins in the keypress of the combo does the same thing but I want this to happen with the mouse (using a double click as it is the only remaining event).

I hope this makes a more clear.

Maybe I should rethink this interface.

Thank you all for your suggestions and ideas. I would surely like to hear a bit more on this from you all. (if possible)

Thanks again.
