Hi,
I have a problems with count of columns on my grid: if I select in first time 4 columns, then I deselect one of thems and I call count method, it gives me 4 always(in event grid.mousedown). Is there anything to do and avoid this?
It looks like the columns isn't de-selected until after the MouseDown event fires. That's a little odd and might be a bug. But I don't think this is something that can be fixed, since it would break existing applications. Event order is not something that can be safely changed in most cases. You can Submit an incident to Infragistics Developer Support and ask them to check it out. Maybe it is possible to fix it.
In the mean time, I recommend using MouseUp.
Thanks,
I use mouseup and it works.
