If I have a TabControlAdv with a SelectedIndexChange event, and in that event I do some processing (such as loading data for the tab that was just selected), the tab control will move the selected tab based on the mouse''s position when the SelectedIndexChange event is complete (I assume it is tracing the mouse down-up position delta and moving the tab accordingly). If I call Application.DoEvents() at the end of the SelectedIndexChange it doesn''t seem to do this.

Hi Don, Sorry for the delay in responding. TabControlAdv activates a tabPage when mouse click (mouse down event) occurs in the tab bounds. For some reason, we could not reproduce the problem. Could you please send us a sample and needed steps to reproduce. It would help us to resolve this issue. Thanks for using Essential Tools. Regards, Mano

Was this fixed?

Hi,

This issue is not fixed yet. After further investigation of this issue, we have to refactor the TabControlAdv source completely (which includes mouse processing logic, selecting\activating TabPages) to fix this issue, as the tab move behavior strongly depends on the mouse-up point.

As previously mentioned, you can set UserMoveTabs property to be false to avoid this issue.

Thanks,
Mano
