NuGet Package: DevExpress.ExpressApp.Xpo

Declaration

C#

public XPInstantFeedbackSourceMappingMode InstantFeedbackMappingMode { get; set; }

VB.NET

Public Property InstantFeedbackMappingMode As XPInstantFeedbackSourceMappingMode

Property Value

Type	Description
XPInstantFeedbackSourceMappingMode	A properties mapping mode in InstantFeedback or InstantFeedbackView mode.

Available values:

Name	Description
AllProperties	All properties should be mapped on a grid.
RequiredProperties	Only visible properties should be mapped on a grid.

Remarks

In InstantFeedback and InstantFeedbackView modes, all property values are calculated at once regardless of grid columns settings. To calculate values only for visible columns, set the InstantFeedbackMappingMode property to RequiredProperties as follows:

C#

builder.ObjectSpaceProviders
    .AddSecuredXpo((serviceProvider, options) => {
        options.ConfigureObjectSpaceProvider = (objectSpaceProvider, serviceProvider)  => {
            objectSpaceProvider.InstantFeedbackMappingMode = XPInstantFeedbackSourceMappingMode.RequiredProperties;
        };
        // ...

To map other columns that do not appear in the grid, add them to the collection of displayed options. See the CollectionSourceBase.DisplayableProperties topic for details.

To define which properties the grid should map for a specific View, use the XPObjectSpace.InstantFeedbackMappingMode property in the target Object Space.
