Ext version tested:

Ext 3.1.1

Adapter used:

only default ext-all.css

Browser versions tested against:

Open "Locking Grid Column" example: http://www.extjs.com/deploy/dev/examples/grid/locking-grid.html
Try mouse wheel over un-locked columns => works fine, the grid content scrolls vertically
Try mouse wheel over locked columns => Bug. No scrolling.

This is a browser limitation and can't easily be solved in Ext.

The left section will only do mouse wheel scroll if it is set to overflow:auto, but that would mean it would show a scrollbar on the right side of the locked section.

hi,I also saw this bug,and that it was not in Ext 4.* ,so i saw the source code of Ext 4.but it looks complicated,so ,can you show me ieda or suggestion to solve this bug above ext 3.3

the code in Ext 4:

view = me.getView();
afterrender: function () {

view.el.scroll = Ext.Function.bind(me.elScroll, me);

me.mon(view.el, {
mousewheel: me.onMouseWheel,
scope: me
single: true
