I use daypilot calendar lite. I've found a good code at this topic (http://forums.daypilot.org/Topic.aspx/420/daypilot_lite__set_color_per_event) for add DurationColor field (i've added to back and fore color fields)
But i would like to use allday events, like in version 6.0 (open source code are in version 3)...
Someone know how can i implement it ? (i'm coding in vb usualy...)
