LinqDataSourceDesigner Class

Definition

Provides design-time support in a visual designer for the LinqDataSource control.

public class LinqDataSourceDesigner : System.Web.UI.Design.DataSourceDesigner
type LinqDataSourceDesigner = class

Public Class LinqDataSourceDesigner
Inherits DataSourceDesigner
Inheritance

Remarks

In a visual designer, when you switch to a designer view (such as Design view in Visual Studio), the LinqDataSource control markup is parsed. A design-time version of the control is then created on the design surface. When you switch to source view, the design-time control is persisted as the markup for the Web page.

The LinqDataSourceDesigner class provides design-time support for the LinqDataSource control in a visual designer.

Notes to Inheritors

To provide commands in a derived class for the action list menu at design time, you must override the ActionLists property. For this property, return a custom DesignerActionListCollection object that contains items that derive from the DesignerActionList object.

For more information, see the DataSourceDesigner class.
