Remarks

When a data source control that supports sorting is bound to the Telerik RadGrid control, the Telerik RadGrid control can take advantage of the data source control's capabilities and provide automatic sorting functionality.

To enable sorting, set the AllowSorting property to true. When sorting is enabled, the heading text for each column field with its SortExpression property set is displayed as a link button.

Clicking the link button for a column causes the items in the Telerik RadGrid control to be sorted based on the sort expression. Typically, the sort expression is simply the name of the field displayed in the column, which causes the Telerik RadGrid control to sort with respect to that column. To sort by multiple fields, use a sort expression that contains a comma-separated list of field names. You can determine the sort expression that the Telerik RadGrid control is applying by using the SortExpression property. Clicking a column's link button repeatedly toggles the sort direction between ascending and descending order.
