Just Dropped in David.

Could you help me with this one.

I have my-combo-class which has a method ReplaceID() just added to it. When I use this class in a form, it has to be populated, prefrably with a dodefault() so I can in future add codes to it in my-combo-class)

What code can I put in my-combo-class.replaceid() to warn me prefrably when I start the form that replaceid() for the combo on the form has not been populated?

The Click-Event of every header is bound (BINDEVENT) to a Sort_On_Column_Of_This_Header Method of the grid itself which provides the sorting on the corresponding column. I just loop through all the column-objects and bind all Click-events of their headers in the init-code of the grid class.

So my idea was just to write Code into the Click-event of the corresponding headers and only bind the click-events of the headers whoes click-events are "empty". So if nothing else specified, the Sort_On_Column_Of_This_Header event of the grid will do its work, otherwise - the Click-Event of the header.
