No, you are correct that such an events do not exist.
Reordering is done by adding and removing the dragged item from the items collection of the TabControl.
There are two ways to be notified about the drag reorder:
1. Inherit the TabCotnrol and override the OnItemsChanged method. In this case distinguishing between other items modifications and the drag reorder may be difficult.
2. Handle the DropQuery event and check for the following conditions which show that a tab has been reordered:
sender, DragDropQueryEventArgs e)
// A handled event, possibly coming from the TabControl:
&& e.Options.Source != e.Options.Destination
// A reordering has just occurred, the e.Options.Source is
// now in the place of the e.Options.Destination
I am attaching a sample project that demonstrates this.
Hopefully this will work for you.
