Telerik.Web.UI.GridGroupByExpression

Expression similar to SQL's "Select Group By" clause that is used by GridTableViewto group items (P:Telerik.Web.UI.GridTableView.GroupByExpressions . Expressions can be defined by assigning P:Telerik.Web.UI.GridGroupByExpression.Expression Expressionproperty and/or managing the items in P:Telerik.Web.UI.GridGroupByExpression.SelectFields or P:Telerik.Web.UI.GridGroupByExpression.GroupByFields collections.

Remarks

If you use P:Telerik.Web.UI.GridGroupByExpression.Expression property to assign group by expression as string then the expression is parsed and P:Telerik.Web.UI.GridGroupByExpression.SelectFields and P:Telerik.Web.UI.GridGroupByExpression.GroupByFields are created. If the expression syntax is incorrect a Telerik.Web.UI.GridGroupByException would be thrown. You can use Telerik.Web.UI.GridGroupByField 's properties to set expression's fields appearance format strings, etc. See P:Telerik.Web.UI.GridGroupByExpression.Expression property for details about the expression syntax.
