Using VFP 5.0a. I am trying to detect when the grid partition size changes and keep all of the code in my grid class. I used the debugger event log to see the events that fire when this is done. The only way I saw of doing it was to save the partition size in the Mousedown method and check to see if it changes in the Mouseup method. Even though the debugger says that the Mouseup event fires it does not run the method code. The MouseDn works.Does anyone know a fix or workaround? The MouseMove is not an option because I am positioning an image in the grid and I don't want it to move around until I'm done.
