The SortDescriptors Collection exposes the Expression property which is used to create flexible sorting conditions. Expression is a string that contains the column name followed by "ASC" (ascending) or "DESC" (descending). Columns are sorted ascending by default. Multiple columns can be separated by commas.

Creating a simple expression:

Copy[C#] Creating simple sorting expression

this.radGridView1.SortDescriptors.Expression = "ShipName ASC";

Copy[VB.NET] Creating simple sorting expression

Me.RadGridView1.SortDescriptors.Expression = "ShipName ASC"

Sorting by two columns using expressions:

Copy[C#] Sorting by two columns, using sorting expression

this.radGridView1.SortDescriptors.Expression = "ShipName ASC, Freight DESC";

Copy[VB.NET] Sorting by two columns, using sorting expression

Me.RadGridView1.SortDescriptors.Expression = "ShipName ASC, Freight DESC"
