I have a grid using a grouping view. The default grouping is on a value called type_display_name. There is also a value called type_color which is a hex color string. I'd like to make the type_color the background color of the group header. I can apply the color as a style in the template used by groupTextTpl, but that only affects the template display and I'd really like to get the color applied in either the div immediately above that (with class x-grid-group-title) or the one above that (with class x-grid-group-hd), so that the color fills the whole header row. The groupTextTpl gets passed a style value that appears to be coming from the x-grid-group-hd div. I tried having my template update that value, but it had no affect. If anyone has a suggestion for how to make this happen, I'd really appreciate the help.
