removing items off a GroupBy area

Hi,

I like the way removing off of items is done in the ReportSample. But I cannot achieve the same result in my view class inherited from CXTPReportView. And I cannot find any specific code in the sample that enables this functionality:

1. A black cross shown over the column's label when user drags and moves the label out of the GroupBy area.
2. removed column returns back to the control

I tried adding m_wndReport.ShowGroupBy() into sample's CTaskListView::OnCreate method. When I open Task Report sample it behaves exactly what I see in my own report view, i.e. it does not remove column's label off the groupBy area.

So what is the trick?

Thank you.

I did try that but no luck. but I also tried to use this

m_wndReport.GetReportHeader()->AllowColumnRemove(TRUE);

this solved the first half of the problem. Now i can see the black cross when move the label outside of the GroupBy area..

Is there any way to have the removed column header to go back to the control. Maybe I could intercept something somewhere :) and add the column being removed back to the report control.


Thank you
