Please see this fiddle:
http://jsfiddle.net/2L6L8xrp/You see there is a frozen column and i'm using datagroup view..
but when i combine it, it looks the datagroup header cannot set the width of groupheader text more than the frozen column width, so it just blank because my groupformatter have a very long text.. so weird
How to solve this?
why dont you make the group header just have the absolute position?
thank you in advance
