I create a datatable and assign it to UltraGrid datasource. The sort order from datatable is not preserved.

e.g. Datatable column sort order (col1, col2, col3). UltraGrid Column sort order (col1, col3, col2).

I want to preserve the UltraGrid column sort order to the sort order in DataTable

e.g. Datatable column sort order (col1, col2, col3).UltraGrid Column sort order (col1, col2, col3).

Please advice

---------------------------------------Here is the code i use.---------------------------

            DataTable _table = new DataTable();

            for (int i = 0; i < _colKeys.Length; i++)
            {
                if (!_table.Columns.Contains(_colKeys[i]))
                {
                    _table.Columns.Add(_colKeys[i], typeof(string));
                    _table.Columns[_colKeys[i]].Caption = _colNames[i];
                }
            }

            _table.Rows.Add(_table.NewRow());   // Value row
            _table.Rows.Add(_table.NewRow());   // NAV row
            _mSummaryGrid.DataSource = _table;
