Sorts data by the values of the specified column.
A String value that specifies the column's field name.
Data can be sorted by multiple columns. Any previous sorting is not cleared when calling the SortBy method.
If the control's data is not sorted by the specified column, the SortBy method sorts data by its values in ascending order. The new sort order applies an additional sorting condition to the one previously applied. The control creates a new GridSortInfo object with the specified settings, and appends it to the GridControl.SortInfo collection. Otherwise, if data is already sorted by the specified column, the SortBy method does nothing.
End-users are allowed to sort data if the view's DataViewBase.AllowSorting property is set to true.
