treeview and mouse scroll wheel

Question

I am sorry but I can't get the mouse scroll wheel to work within a treeview. I have looked at  the threads about mousewheel and they deal with questions about how it scrolls - I can't get it to scroll at all.

I have tried clicking the wheel before scrolling, opening up a node witha  mouse click and then trying to scroll, but nothing ever happens.

Is somebody able to help.

Thanks - Stephen

Answer 1

Did ever work? It looks like is from mouse or mouse driver. You may test it with other mouse.

Answer 2

Thanks for replying. I have tried it with both wired and wireless mice and nothing. Vertical scroll bars are visible in the treeview but the mouse wheel does nothing.

Both mice wheels work with other programs.

 

Answer 3

I had that problem in a browse window, but mouse started to work after restart. You may put in main form MouseWheel method NODEFAULT, and disable windows theme property...

Answer 4

Thanks - it hasn't woken up and worked yet. I have now put the treeview on page 1 of a pageframe, and a grid on page2. The mouse works within the grid as normal so it is something about the treeview - odd.

Thanks for asking Ed

Solved in that I abandoned the issue and designed the form a different way :-)
