WPF 4.5 – Part 11 : New features for the VirtualizingPanel

posted by

jmix90 590 days, 13 hours, 31 minutes ago

Virtualizing panels are involved when an application’s performance needs to be improved. It provide a base panel for virtualization of children elements inside it. Instead of creating all the UI element which are inside an ItemControls, only the one which need to be displayed are created. Because the process of creating these elements is intensive, the use of a VirtualizingPanel makes an item controls display faster. The VirtualizingPanel comes with new features in WPF 4.5: two properties named ScrollUn... (more)

posted by

jmix90 592 days, 17 hours, 29 minutes ago

For each item list used in a WPF application, a collection view is in fact created and used by the controls. This view enables navigation, filtering, grouping and sorting from the XAML or the code. It is a very powerful feature that is offered to the developers since a long time in WPF. In WPF 4.5 as in WPF 4.0 the grouping, sorting and filtering operations are done when the item is added to the collection or when the Refresh method is called. The drawback is that if an item property value involved in o... (more)

WPF 4.5 – Part 9 : binding to static properties

posted by

jmix90 599 days, 9 hours, 11 minutes ago

There is two different ways to make a property bindable: implementing INotifyPropertyChanged is the most known solution, the other one is to create a event named PropertyNameChanged. In WPF 4.0 there is no way to create a static property which can be used by a binding with property change notifications. In this post, part of a serie on the WPF 4.5 new features, we’ll see how it can now be done! (more)

Integrating win 32 component is already possible in WPF 4.0, even in WPF 3.5 but there is the well-know issue : airspace problems. Each render technology belongs to only one airspace only. So when you place Win32 components in your WPF application they behave as black hole for input, render transformation are not (well) applied, etc. With this 4.5 release, the WPF team solves this drawback.

Here is the seventh (OMG !) post on the WPF 4.5 new features. Collections are a part of every application and their management is maybe the first thing you learn to deal with in WPF. To begin, you put everything on the main(the UI one) thread and it works just fine. After a few time, you realize that it freezes the application UI and that the users usually don’t like it. Then you put the collections creation/feeding on another Thread to free the UI’s one and you realize that it is not possible because :... (more)

If you read the MSDN page on the new WPF 4.5 features, you’ll find it under the label “Automatically updating the source of a data binding“. This is more precise and understandable to me to say that a ‘Delay’ property has been added to the Binding markup extension ! This post is a part of the serie on WPF 4.5 new features.

When working with different iterations of a SQL database running on Internal, Staging and Production infrastructure it can become a pain in the ass rolling out updates at deployment time or keeping them in sync. Developers often use third party tools to help them do this job, however depending on what version of Visual Studio you have installed, there may be another option you have overlooked, and it’s baked right into the IDE.

[RIA Services] Why the client extended entities won't use the default backing store value ?

The title may not be clear but I am talking about the entities that you extends on the client side using the fact that they are partial class. You may think as I was that if you add properties in them with backing store field, the properties will get initialed nicely : this is not the case and the property will always use the default value for the property type. In this post we’ll discover how to perform our goal : create a property with the correct default value. (more)

[RIA Services] How to force validation on my entities (and just the validation !)

published 942 days, 10 hours, 59 minutes ago posted by

jmix90 943 days, 21 hours, 24 minutes ago

RIA services solves for you a lot of problems and one of them is to add validations rules on the entities both on the client and on the server side. These differents rules are checked when you submit the changes from the client to the server or when you call “EndEdit” on the entities. But there is times when you want to leverage the validation without submit the changes or commit your object modification (in a IEditableObject way of talking). In this post we will discover how to do just this. (more)
