Property Value

Type Default Description
ColumnSortMode Default

The sort mode for column data.

Available values:

Name Description

The actual sort mode is determined by a control. See the property description for more details.


Sorts the column’s data by the column’s edit values (these are synchronized with the bound data source’s values).


Sorts the column’s data by the column’s display text (the strings displayed within the column’s cells).


Applies sort options specified in the CustomColumnSort event handler.

In data grids, this mode also applies group options from the CustomColumnGroup event handler.


The SortMode property determines the algorithm used to sort column data (by display text, edit value, or custom sort algorithm).

The Default option is DisplayText for columns that use LookUpEdit and ImageComboBoxEdit in-place editors. The Default option is Value for other columns.

Set the SortMode property to ColumnSortMode.Custom and handle ColumnView.CustomColumnSort and GridView.CustomColumnGroup events to apply custom sort and group options.

Set the GridColumn.SortOrder property to ColumnSortOrder.Ascending or ColumnSortOrder.Descending to sort column data. As a result, the GridControl arranges column values in ascending or descending order based on the algorithm specified by the SortMode property.


In server mode, do not use the SortMode property to enable data sorting and grouping by display values. Use the GridColumn.FieldNameSortGroup property instead.

See the Custom sorting module demo which shows how to sort a string column with decimal values.

    // Custom Column Sorting            
    GridColumn column = gridView.Columns["Length"];
    column.SortMode = ColumnSortMode.Custom;
    gridView.CustomColumnSort += (sender, e) => {
        // Always show 0 at the bottom
        if (e.Column.FieldName == "Length") {
            if ((double)e.Value1 == 0 && (double)e.Value2 != 0) {
                e.Result = e.SortOrder == ColumnSortOrder.Ascending ? 1 : -1;
            else if ((double)e.Value2 == 0 && (double)e.Value1 != 0) {
                e.Result = e.SortOrder == ColumnSortOrder.Ascending ? -1 : 1;
            else {
                // default comparison
                e.Result = Comparer.Default.Compare(e.Value1, e.Value2);
            e.Handled = true;
    column.SortOrder = ColumnSortOrder.Ascending;
