Property Value

Type	Description
Action<DevExpress.ExpressApp.AuditTrail.CustomizeAuditDataStoreContext>	A delegate method that takes the event context object as an argument.

Remarks

Use this property to customize the audit data store’s settings. For example, the code below demonstrates how to specify a custom null value string for the audit data store:

File: MySolution.WebApi\startup.cs (MySolution.Blazor.Server\startup.cs)

C#

builder.Modules
    .AddAuditTrailXpo(options => {
        options.Events.OnCustomizeAuditDataStore = (context) => {
            context.AuditDataStore.NullValueString = "CustomNullValueString";
        };
    })

You can also register the audit trail services directly as the code below demonstrates:

File: MySolution.WebApi\startup.cs (MySolution.Blazor.Server\startup.cs)

C#

services
    .AddAuditTrailXpoServices(options => {
        options.Events.OnCustomizeAuditDataStore = (context) => {
            context.AuditDataStore.NullValueString = "CustomNullValueString";
        };
    })
