Hi,

please, how can I recognize whether the user has resized a column with the resize-splitter?

I cannot detect any event that fires!?!

THX!

Well, for MFC version there is a special event, which unfortunately is not yet published for ActiveX: called COLUMN WIDTH CHANGED.
It could be available for the next version however.

Do U know any workaround to detect a column-width-change by the user?

Try handling MouseDown event -- look for a regular sample application for an example. There you can detect whether a Column Header Area was clicked (this might be a resizing click).

Sorry, my last answer was too fast - and wrong!

With the MouseDown-Event i can only detect the actually column-width, not the new column-width(!!!). And the MouseUp-Event does not fires if the user hast column-sizing finished! ;-(

So i hope you can add the "COLUMN WIDTH CHANGED" Event to the next release! THANK YOU!!!

I have maked a workaround with a timer.

In the ColumnsAdd i store the width in the tag and every 100 ms, i check if the actual width is changed to the stored width.

It's working nice and easy.

@Baldur

Okay, but U've always a heavy timer (for a little Feature) in Ur App!

I check the columnwidth on "Lost Focus". But both is only a workaround - so I will hope that the Codejock-guys have a heart for us and put this event to the next release! ;-)

I now use MouseDown and MouseUp-Event.

in MouseDown i store the active column (from hittest), in MouseUp i check for changed width's.

If no width is changed, i compare with the stored column, if the column is not changed, this is a single-column-click.

Heavy, but it works correct.

(I can't wait for the next version.)
