Posted 8 September 2017, 3:33 am EST<P>Hello everyone,
I meet a problem and sincerely ask for your help.</P>
<P>Current Proccesses: </P>
<P>select a range of cells by mouse's left button => show popup menu</P>
<P> MouseDown => MouseUp</P>
<P>When the event "MouseUp" happened in the "RowHeader" or "ColumnHeader" or "SheetCorner" range of the spread, with the menu popupping, if the mouse moves, the range of the selections changes.
However, when the event "MouseUp" happened in the "cells" range of the spread, everything is ok.</P>
<P>I can't figure out what the difference between this two and I'm wondering how could this happens.
I tried to add "e.Cancel = True" in the "SelectionChanging" Event, but make no effect.
Can anyone help me?
