RepositoryItem.ReadOnly Property

Gets or sets a value specifying whether the editor’s value can be changed by end-users.

Namespace: DevExpress.XtraEditors.Repository

Assembly: DevExpress.XtraEditors.v19.1.dll

Declaration

C#

[DXCategory("Behavior")]
public virtual bool ReadOnly { get; set; }

VB.NET

<DXCategory("Behavior")>
Public Overridable Property ReadOnly As Boolean

Property Value

Type	Description
Boolean	true if end-users can not modify editor’s value; otherwise, false.

Remarks

Use this property to specify whether the editor’s value can be modified by an end-user.

Note: if the editor displays a text box, end-users are allowed to access the edit value. They can select the desired content’s portion and copy it to the Clipboard, for instance. If you need to prevent such actions, set the RepositoryItem.Enabled property to false.

Changing the ReadOnly property value raises the RepositoryItem.PropertiesChanged event.
