Removing column header separator lines (flex)
This took me a while to figure out so I thought I would post it on here just in case someone else is having the same problem. I have an Advanced Data Grid, but I don't want any separator lines between the headers. There are 2 styles and 1 property you need to set in an AdvancedDataGrid to make this happen. The styles are: header-separator-skin header-sort-separator-skin The property is: sortExpertMode I figured setting the styles to "null" would work, but it doesn't. Here is what you need to do: headerSortSeparatorSkin="mx.skins.ProgrammaticSkin" headerSeparatorSkin="mx.skins.ProgrammaticSkin" sortExpertMode="true" Or if you'd rather set the styles in CSS: header-separator-skin: ClassReference("mx.skins.ProgrammaticSkin"); header-sort-separator-skin: ClassReference("mx.skins.ProgrammaticSkin"); Sample with source Thanks to http://theflexguy.com/index.php?option=com_idoblog&task=viewpost&id=104&Itemid=54...
