ASPxPropertyEditor Class

The base class for Property Editors that use controls inherited from DevExpress.Web.ASPxEditBase.

Namespace:DevExpress.ExpressApp.Web.Editors.ASPx
Assembly:DevExpress.ExpressApp.Web.v17.1.dll

Expanded Syntax

Expanded Remarks

A custom Property Editor that uses a control from the ASPxEditors library can be implemented by inheriting from either the WebPropertyEditor or ASPxPropertyEditor class. The difference is that in the latter case, the ReadEditModeValueCore method does not have to be overridden. This method deals with the binding property of the control used in edit mode. It assigns the Property Editor's PropertyValue to the edit mode control's binding property. The ASPxPropertyEditor class already contains the default implementation of this method, given that all the controls from the ASPxEditors library have the same binding property - the Value property of the object type.

The ASPxPropertyEditor also introduces the ASPxEditor member. It returns a DevExpress.Web.ASPxEditors.ASPxEditBase object that represents the Property Editor's control used in edit mode.

To instantiate ASP.NET Web controls in the CreateEditModeControlCore and CreateViewModeControlCore methods, use static helper methods of the RenderHelper class.

The built-in XAF ASP.NET Property Editors inherit from the ASPxPropertyEditor class.

When inheriting from the ASPxPropertyEditor class, subscribe to the control's ValueChanged event to call the EditValueChangedHandler method (raises the PropertyEditor.ControlValueChanged event and calls the PropertyEditor.WriteValue method).

Note

A custom Property Editor that derives from the ASPxPropertyEditor should not throw exceptions. Exceptions thrown by such a Property Editor interrupt request processing. As a result, the application crashes.

To see an example of a Property Editor derived from the ASPxPropertyEditor class, refer to the following topics:
