ASPxQueryBuilder.StaticInitialize() Method

Explicitly starts the Query Builder initialization.

Namespace: DevExpress.XtraReports.Web

Assembly: DevExpress.XtraReports.v24.1.Web.WebForms.dll

NuGet Package: DevExpress.Web.Reporting

Declaration

public static void StaticInitialize()

Remarks

The ASPxQueryBuilder is automatically initialized when rendering on your application’s Web page, but in specific cases, you need to trigger its initialization explicitly (for instance, when an AppPool is recycled).

The StaticInitialize method does the following:

  • Calls the static ASPxQueryBuilder constructor;
  • Registers HttpHandlers required for the Query Builder;
  • Initializes all services for processing requests to the corresponding handler.

Use the StaticInitialize method at the application startup in the Global.asax file.

Note

To make the Query Builder’s handlers work correctly, you should call this method after specifying the session state and registering additional services.

protected void Application_Start(Object sender, EventArgs e) {
    // ...  
   DevExpress.XtraReports.Web.QueryBuilder.Native.QueryBuilderBootstrapper.SessionState = 
        System.Web.SessionState.SessionStateBehavior.Required;
    // ...  
    DevExpress.XtraReports.Web.ASPxQueryBuilder.StaticInitialize();
}
