Another member when using code in one of my articles came across a peculiarity that I'm trying to resolve.
It seems that whenever the DataSource of a DataGridView is changed, if the mouse is over the Control, a WM_MOUSEMOVE (0x0200) message is generated http://www.barakasoft.com/script/Forums/Images/smiley_confused.gif
Is there any reason why this would be the case, and any idea of a workaround as the component does something on that message so this situation is causing undesired and unexpected behaviour!?
The only quick workaround I can think of is to store and check against the previous lParam of this message to see if the mouse has actually moved - yuk! Dave

BTW, in software, hope and pray is not a viable strategy. (Luc Pattyn (http://www.codeproject.com/Members/Luc-Pattyn))
