I have a listgrid. I customize grid summary, I have the next options:
setGroupByField("class_desc");
setGroupStartOpen(GroupStartOpen.ALL);
setShowGridSummary (true);
setShowGroupSummary (true);
setShowGroupSummaryInHeader (true);
But I can not make me show the division between categories, what am I doing wrong?
I'm sure the function name setGroupByField
is the same as the datasource.
