The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Note: This API is now obsolete.

Gets or sets a value indicating whether the properties of the control are read-only at design time.

Namespace:   System.Web.UI.Design
Assembly:  System.Design (in System.Design.dll)

[ObsoleteAttribute("The recommended alternative is to inherit from ContainerControlDesigner instead and to use an EditableDesignerRegion. Regions allow for better control of the content in the designer.")]
public bool ReadOnly { get; set; }

Property Value

Type: System.Boolean

true, if the properties of the control are read-only at design time; otherwise, false.

The ControlDesigner class is read-only, by nature. Read/write features are provided by adding a DesignerRegion object or using base classes, such as the ContainerControlDesigner class.


The ReadOnly property is obsolete. Derive from the ContainerControlDesigner class to which you can add editable designer regions or from the TemplatedControlDesigner object to which you can create editable designer regions in templates.
