Getting first row after sorting
posted

I'm probably overlooking something, but I can't seem to fetch the first row of an UltraCombo after sorting. A row is returned, but it's not the first one.

I'm sorting like this:

machineCodeUltraCombo.DisplayLayout.Bands[0].SortedColumns.RefreshSort(

false);

after that, I tried some different ways of getting the first displayed row:

firstRow = machineCodeUltraCombo.Rows.SingleOrDefault(r => r.VisibleIndex == 0);

firstRow = machineCodeUltraCombo.Rows[0];

firstRow = machineCodeUltraCombo.DisplayLayout.Rows[0];

firstRow = machineCodeUltraCombo.DisplayLayout.Rows.GetRowAtVisibleIndex(0);

 

All these options return the same (wrong) row.

    First you should add the columns to the sorted columns collection, like 

    machineCodeUltraCombo.DisplayLayout.Bands[0].SortedColumns.Add("desired column", flag indicator for ascending or descending", Groupby flag);

    And than you could take the FirstRow like:

    firstRow = machineCodeUltraCombo.DisplayLayout.Rows[0];

    About the following line it would refresh the already sorted columns.

      machineCodeUltraCombo.DisplayLayout.Bands[0].SortedColumns.RefreshSort(

    false);

    Please let me know if you have any further questions about this issue.
