DxGridDataColumn.SortOrder Property

Specifies the column’s sort order (ascending or descending).

Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(GridColumnSortOrder.None)]
[Parameter]
public GridColumnSortOrder SortOrder { get; set; }

Property Value

Type	Default	Description
GridColumnSortOrder	None	A GridColumnSortOrder enumeration value.

Available values:

Name	Description
None	Grid sorts column data in ascending order.
Ascending	Grid sorts column data in ascending order.
Descending	Grid sorts column data in descending order.

Remarks

When you specify a column’s SortIndex property, the grid sorts column data in ascending order. Use the SortOrder property to change the sort order.

The following example sorts Grid data by the Freight column in descending order, and then sorts data by the Order Date column in ascending order:
