This page lists the important behavior and API changes that were introduced in this version. If you already have projects using DevExpress .NET products, you will need to peruse this list in order to understand the changes you might need to make to your source code to support this new release.

Note that we only publish the changes to the public interface of our controls. We reserve the right to change the protected, internal, or private interfaces when needed.

eXpressApp Framework

• # BC3086: The GetCriteriaWrapper method has been removed from the DevExpress.ExpressApp.Kpi.IKpiDefinition interface.

Internal XAF code doesn't use this method, so we have decided to remove it. After migrating to a new version you can encounter the following error in VB.NET projects generated using the Solution Wizard for Entity Framework Model First:

BusinessObjects\KpiDefinition.vb(287,120): error BC30401: 'GetCriteriaWrapper' cannot implement 'GetCriteriaWrapper' because there is no matching function on interface 'IKpiDefinition'.

In this case, remove the declaration of the explicit implementation for this method:

Old code:

[VB.NET]

Public Function GetCriteriaWrapper(ByVal rangeStart As Date, ByVal rangeEnd As Date) As CriteriaWrapper Implements DevExpress.ExpressApp.Kpi.IKpiDefinition.GetCriteriaWrapper

New code:

[VB.NET]

Public Function GetCriteriaWrapper(ByVal rangeStart As Date, ByVal rangeEnd As Date)

• # BC3084: The ShowViewStrategy.CollectionsEditMode property has no effect anymore.

Use the IModelOptionsWeb.CollectionsEditMode property instead. You can change its value using the Model Editor invoked for the ASP.NET project. The property is located in theOptions node.

XtraBars Suite

• # BC3111: The purpose of the BarEditItem.Width property has been changed

Previously, BarEditItem.Width specified the editor width. Now, the new BarEditItem.EditWidth property should be used for this purpose. The BarEditItem.Width property will be used to specify the entire item width. We have made this change to fix the problem described in this ticket: The BarButtonItem.Width property has no effect.

XtraLayout Suite

• # BC3105: Displaying Nested Objects as Groups feature was disabled by default

Analyzing our customers' feedback, we decided to continue support the old behavior when the Auto Retrieve Fields feature populates only top level properties and make the old behavior to be default. We added a special option to switch between the old and new strategy: DataLayoutControl.AllowGeneratingNestedGroups.

To retrieve fields with generating nested groups, set the DataLayoutControl.AllowGeneratingNestedGroups property to DefaultBoolean.True.
