Remarks

According to the time settings specified in the CacheCleanerSettings class, the default cleaner service periodically checks if the memory cache contains documents/reports whose lifetime exceeds a specific amount of time. If such documents/reports are found, they are deleted. You can register a new instance of the CacheCleanerSettings class with required time settings using the DefaultWebDocumentViewerContainer.Register<T, TImpl> (.NET Framework)/ AddSingleton (.NET Core) method.

The following code demonstrates how to register custom settings in a .NET Framework application.

C#

using DevExpress.XtraReports.Web.WebDocumentViewer;
//... 
  void Application_Start(object sender, EventArgs e) {
    var dueTime = TimeSpan.FromSeconds(30);
    var period = TimeSpan.FromSeconds(30);
    var reportTimeTolive = TimeSpan.FromSeconds(30);
    var documentTimeToLive = TimeSpan.FromSeconds(30);
    DefaultWebDocumentViewerContainer.RegisterSingleton<CacheCleanerSettings>(new CacheCleanerSettings(dueTime, period, reportTimeTolive, documentTimeToLive));
  }
//...

VB.NET

Imports DevExpress.XtraReports.Web.WebDocumentViewer
'... 
  Sub Application_Start(sender As Object, e As EventArgs)
    Dim dueTime = TimeSpan.FromSeconds(30)
    Dim period = TimeSpan.FromSeconds(30)
    Dim reportTimeTolive = TimeSpan.FromSeconds(30)
    Dim documentTimeToLive = TimeSpan.FromSeconds(30)
    DefaultWebDocumentViewerContainer.RegisterSingleton(Of CacheCleanerSettings)(New CacheCleanerSettings(dueTime, period, reportTimeTolive, documentTimeToLive))
  End Sub

//... 

public class Startup {
//... 
  public void ConfigureServices(IServiceCollection services) {
    services.AddDevExpressControls();
    services.AddMvc();

    var period = TimeSpan.FromSeconds(30);
    var reportTimeTolive = TimeSpan.FromSeconds(30);
    var documentTimeToLive = TimeSpan.FromSeconds(30);
