PropertyEditor.ImmediatePostData Property

Specifies whether the property editor’s control value should be passed to the property of a bound object as soon as possible when the value is changed by user. For instance, it allows you to enforce updating other displayed values that are calculated based on the current property.

Namespace: DevExpress.ExpressApp.Editors

Assembly: DevExpress.ExpressApp.v23.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public bool ImmediatePostData { get; set; }

VB.NET

Public Property ImmediatePostData As Boolean

Property Value

Type	Description
Boolean	true if the property editor’s control value should be passed as soon as possible; otherwise, false.

Remarks

This property derives its default value from Views | <DetailView> | Items | <PropertyEditor> | ImmediatePostData and Views | <ListView> | Columns | <Column> | ImmediatePostData.

Refer to the ImmediatePostDataAttribute topic for details.

The example below demonstrates how to apply ImmediatePostData to FirstName and LastName. This causes the calculated FullName field to update automatically in WinForms applications.

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Win.Editors;
// ...
public class FullNameController : ObjectViewController<DetailView, MainDemo.Module.BusinessObjects.Contact> {
    protected override void OnActivated() {
        StringPropertyEditor firstNameEditor = (StringPropertyEditor)View.FindItem("FirstName");
        StringPropertyEditor lastNameEditor = (StringPropertyEditor)View.FindItem("LastName");
        firstNameEditor.ImmediatePostData = true;
        lastNameEditor.ImmediatePostData = true;
    }
}

VB.NET

Imports DevExpress.ExpressApp
Imports DevExpress.ExpressApp.Win.Editors

Public Class FullNameController
    Inherits ObjectViewController(Of DetailView, MainDemo.Module.BusinessObjects.Contact)
    Protected Overrides Sub OnActivated()
        Dim firstNameEditor As StringPropertyEditor = CType(View.FindItem("FirstName"), StringPropertyEditor)
        Dim lastNameEditor As StringPropertyEditor = CType(View.FindItem("LastName"), StringPropertyEditor)
        firstNameEditor.ImmediatePostData = True
        lastNameEditor.ImmediatePostData = True
    End Sub
End Class
