Hi;

How can I prevent a reorder of columns, but only when dropped outside a distinct range of columns.

I could not find something similar to a OnColumOrderChanging notification message. I only get the changed notification.

To be more precise: we have a report control that consists of three "parts" regarding the shown columns. Due to legacy reasons we can not use three different controls containing only the columns of each of the three parts and synchronize the navigation in any of the three controls with the other two.

Nevertheless, we have to avoid section overlapping column reorder, but within a "section" reorder should be possible.

Therefore, my question for a OnColumnOrderChanging function.
