This example describes how to use our file manager control with the Azure File storage / File Service. The main idea is to create a custom file system provider and use Azure SDK to implement all required operations. As a starting point, it is possible to use the Get started with Azure File storage on Windows Microsoft documentation.
To run the example, define the AccountName, KeyValue, and FileShare constants with your credentials in the AzureFileStorageProvider class.
Please note that the Azure Blob Storage is supported in our ASPxFileManager by default. You can review our Demo, where it is shown how to configure the file manager in this case.

The XAF Audit Trail module is intended to track changes being made in persistent objects. This module uses the AuditTrailService class to track changes and write them to the database. It is possible to use this API in a non-XAF application based on XPO, without creating and configuring the DevExpress.ExpressApp > XafApplication object as it is usually done in XAF apps.
To use these features of the Audit Trial module, you will need to reference the DevExpress.Persistent.BaseImpl and DevExpress.Persistent.Base assemblies, which are part of the standard XAF delivery package.
Important notes:
1. You need to have a valid license for the eXpressApp Framework to use this example.
2. AuditTrailService cannot be used with ExplicitUnitOfWork. Use UnitOfWork or Session classes to audit data through AuditTrailService. AuditTrailService creates a new session to save audit records based on the data layer of the audited session. So, the data layer becomes shared among this new temporary session and ExplicitUnitOfWork. This violates the "exclusive owner of the database connection" requirement of ExplicitUnitOfWork.

I've created a separate ticket on your behalf and suggest you continue discussing this issue in the context of this thread: T562012: E4029 example doesn't work in the Edge browser. I will answer you there shortly.
The best solution to display calculations based on the huge amount of data within the PivotgridControl or ASPxPivotGrid is to create the OLAP Cube and perform all calculations on the SQL server side.
If you cannot use OLAP data source, I suggest you use PivotGrid in the server mode. In version 14.2 we have introduced the server mode support in PivotGrid, thus the approach described in this example is not actual any more. We have added the Obsolete prefix to emphasize this statement. To enable Server Mode, use the following components depending on the target platform:
- ASP.Net - EntityServerModeDataSource and LinqServerModeDataSource;
- Windows Forms - EntityServerModeSource and LinqServerModeSource;
- WPF - EntityServerModeDataSource and LinqServerModeDataSource.
In previous versions it's possible to slightly improve the performance when the PivotgridControl or ASPxPivotGrid is bound to the DataSet. The main idea is to group data when retrieving them from the database. This way, calculations performed on the client side will be reduced, and the pivot grid will load and sort data faster. In this instance, it's necessary to update the data source each time the user moves fields between areas. Otherwise, the pivot grid will display incorrect values.
This example demonstrates how to implement this in a simple case.

I'm trying to run the example code you provided but it seems that some changes should be applied in order for it to work. Can you please specify the changes or prerequisites required for this code to run successfully.
Added By: Sean Winstead 2 at: 12/24/2014 12:15:26 PMI made use of this example in our own code. But I think the Count aggregation doesn't work as expected in certain situations. For example, let's say the report needs to show the # of jobs. The summary type of the field is set to Count. The dynamically-created query includes COUNT(JobID) and the result set includes 3 rows:
Row 1, COUNT(JobID) = 1
Row 2, COUNT(JobID) = 2
Row 3, COUNT(JobID) = 1
The sum of the counts is 4 which is the correct # of Jobs.
But let's say the grid has to perform additional grouping and in our example all 3 rows are combined into one row in the grid. In this case, the grid will display the number of rows (i.e., 3) instead of summing the rows. So the # of jobs is understated by 1 in the rendered report.
Any advice on how to work around this?

I've created a separate ticket for your question on your behalf (T612962: How to write changed data back to the table at detail level ). It has been placed in our processing queue and will be answered shortly.
LayoutGroup/LayoutControl doesn't have the built-in ItemsSource property. In this example, we demonstrated how to provide this functionality using a custom behavior class. This behavior generates LayoutItem controls when the associated collection is changed and adds them to the Children collection of the associated control.
And you also need a guard on ArrangeChildren():[C#]protectedoverridevoidOnAttached(){base.OnAttached();ArrangeChildren();}
[C#]{if(AssociatedObject==null)return;
Hi Andrew,
Your approaches are absolutely correct. I have updated this example to apply them and slightly changed the implementation to make it possible to attach our custom behavior to individual groups. It is now unnecessary to obtain groups by their names, and you also can populate multiple groups within your LayoutControl dynamically.
As for the last issue, please check if it exists in the updated example and let me know your results.
[C#]if(e.Action==NotifyCollectionChangedAction.Reset){varunwantedItems=newList<FrameworkElement>();foreach(varchildinAssociatedObject.Children){if(childisFrameworkElementelement){if(element.DataContextisButtonDescriptor)unwantedItems.Add(element);}}foreach(varunwantedIteminunwantedItems){AssociatedObject.Children.Remove(unwantedItem);}}

So, if your custom size is ignored using the aforementioned method, you may want to research the source code for each required form template and adjust your default form settings accordingly.

The sample illustrates how to save the current ASP.NET MVC Dashboard state (such as master filter or parameter values) to cookies on the client side and restore this state on the server side. The following API is used in this example:
- The ASPxClientDashboard.DashboardStateChanged event is handled to obtain the current dashboard state.
- The ASPxClientUtils.SetCookie client-side method is used to save the dashboard state to cookies.
- The DashboardConfigurator.SetDashboardStateService method is used to apply the dashboard state loaded from the cookies.
