PropertyEditor.WriteValue() Method

Sets the value that is specified in the current Property Editor's control for the bound property.

Namespace: DevExpress.ExpressApp.Editors

Assembly: DevExpress.ExpressApp.v18.1.dll

Declaration

public void WriteValue()
Public Sub WriteValue

This method writes the value that is set for the current Property Editor's control to the related property (see PropertyEditor.PropertyName). After that method, the PropertyEditor.PropertyValue property is set to the PropertyEditor.ControlValue property value.

You can modify the process of saving the control's value to the property using the following events: PropertyEditor.ValueStoring, PropertyEditor.ControlValueChanged and PropertyEditor.ValueStored.

The WriteValue method is not called in the Windows Forms Property Editors because they support Binding (see System.Windows.Forms.Binding in MSDN). However, the PropertyEditor.ValueStoring, PropertyEditor.ControlValueChanged and PropertyEditor.ValueStored events are additionally raised. So, when implementing a descendant of the PropertyEditor class that supports binding, call the OnValueStoring and OnValueStored methods where required, so that you can subscribe the corresponding events. If you implement a Property Editor and do not use Binding, override the WriteValueCore method if you need to perform additional actions, except setting the PropertyValue to the ControlValue. In this instance, you do not have to be concerned with raising the corresponding events.
