LinqDataSource::AutoGenerateOrderByClause Property
Gets or sets a value that indicates whether the LinqDataSource control dynamically creates an Order By clause based on values in the OrderByParameters collection.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
public: property bool AutoGenerateOrderByClause { bool get (); void set (bool value); }
<asp:LinqDataSource AutoGenerateOrderByClause="True|False" />
Property Value
Type: System::Booleantrue if the LinqDataSource control creates the Order By clause; otherwise, false. The default is false.
When you set the AutoGenerateOrderByClause property to true, the LinqDataSource control dynamically creates an Order By clause that is based on the values in the OrderByParameters collection. The LinqDataSource control sorts the data by the first parameter and then additionally sorts the data for each additional parameter. Parameters that contain nullptr or an empty value are not included in the Order By clause.
You do not set the OrderBy property when the AutoGenerateOrderByClause is set to true, because the parser dynamically creates the Order By clause. The LinqDataSource control throws an exception if the AutoGenerateOrderByClause is set to true and the OrderBy property is assigned values.
The following example shows a LinqDataSource control with the AutoGenerateOrderByClause set to true. A parameter is included in the OrderByParameters collection that orders the data based on the property name that a user selects from a DropDownList control.
