Hello

Is there any support for multi-column sorting in the ReportControl?
How can I change it, upon user column's sort selection?

Thanks

Yes, there is.

This sample illustrates how to sort the columns in the ReportControl. If you had 8 columns added to the ReportControl, this sample would sort the columns first by the column at Itemindex 7, then by the column at ItemIndex 2, then by the column at ItemIndex 5.

    'This code below will add three columns to the SortOrder collection of coluns.
    'This will cause the columns in the ReportControl to first be sorted by column 7,
    'which has an index of zero (0) in the SortOrder collection. Columns are first sorted
    'in the order that they are added to the SortOrder collection.
    wndReportControl.SortOrder.Add wndReportControl.Columns(7)
    wndReportControl.SortOrder.Add wndReportControl.Columns(2)
    wndReportControl.SortOrder.Add wndReportControl.Columns(5)

    'This will cause the column at index 0 of the SortOrder collection to be sorted
    'in descending order.
    wndReportControl.SortOrder(1).SortAscending = False
