ImmediatePostDataAttribute Class

Indicates the refresh behavior for a business class property.

Namespace:DevExpress.Persistent.Base
Assembly:DevExpress.ExpressApp.v17.1.dll

Expanded Syntax

Expanded Remarks

If the ImmediatePostData attribute is applied to a business class property, changing the property value causes an immediate refresh of the current page in an ASP.NET application. In a Windows Forms application, update of the current property's value is executed immediately when it is changed, rather than on the loss of input focus.

If the ImmediatePostData attribute is used, the IModelCommonMemberViewItem.ImmediatePostData property of the Application Model's BOModel | <Class> | OwnMembers | <Member> node is set to true. Otherwise, it is set to false. Note - you can set or change this property's value via the Model Editor.

To see an example of using the ImmediatePostData attribute, refer to the Make a Property Calculable topic.

Note

This functionality has certain limitations in an editable List View in ASP.NET applications. Please ensure that the application behavior meets your requirements before publishing your application. You can always disable ImmdediatePostData for a specific column using the IModelCommonMemberViewItem.ImmediatePostData property of the Views | <ListView> | Columns | <Column> node in the Model Editor invoked for the ASP.NET project. Feel free to contact the XAF support team if you experience any difficulties.
