<DefaultValue(-1)>
Public Property SortIndex As Integer

Property Value

Type	Default	Description
Int32	-1	The column’s sort priority. -1 if the grid does not sort its data by the column.

Remarks

ASPxGridView allows users to sort its data by multiple columns. Use the SortIndex property to define the column’s sort priority among columns.

When you change the SortIndex property value, the control automatically sets the column’s SortOrder property to Ascending.

If the SortIndex property is set to -1, the control does not sort its data by this column.

For more information on sorting in the grid, refer to the following topic: ASPxGridView - Sort Data.
