Re: Changes Opacity for vertical scrollbar inside 2.4 DataGrid?

DataGrid uses a CustomScrollPanel for its data table. Such panel uses transparent-style native scrollbars, but the resources used (NativeVerticalScrollbar.ResourcesTransparant) are hardcoded in the CustomScrollPanel constructor. I guess you can:

- extend the DataGrid to obtain a reference of the inner CustomScrollPanel. See [1] on how to do that;
- extend the default NativeVerticalScrollbar.ResourcesTransparant to provide your own style (or use the no-op NativeVerticalScrollbar.Resources to remove any opacity);
- in the extended DataGrid constructor, after super(), use the CustomScrollPanel reference to set up a new scrollbar using the method setVerticalScrollbar(...) passing in a new NativeHorizontalScrollbar with your new resources.

The same applies for the horizontal scrollbar.

Or you can look at the DOM and figure out some hack to obtain the scrollbar container (as you tried).
