Question

On the control appears a feature saying ‘Drag a column header to gorup by that column’. Can i do that programmatically. Are there any properties or do I need to embed SQL statements?

Thanks,
Sun

Answer 1

You need to add the column to the SortedColumns collection in the band:

    private void SwitchGroupByFor(string key) //key stands for the ultragridcolumn key
    {
        var band = grid.DisplayLayout.Bands[0];
        var sortedColumns = band.SortedColumns;

        sortedColumns.Add(key, false, true); //last flag indicates is a group by column
    }
