While browsing Microsoft Translator interactive SDK pages, I noticed at their Create a Web Widget page, at the HTML tab, that the sample HTML code was using the fieldset and legend tags. Very interesting tags, "fieldset" produces a nice looking group box around the HTML content it encloses, whereas "legend" tag's content is the groupbox's caption. I wonder though Διαβάστε περισσότερα »...

I will also demonstrates the new features of the GridView control Διαβάστε περισσότερα »...

My good friend Martin Praxmarer while we are working on some cool feature for the new ModelDifference eXpand module pointed out the existence of an evil switch Suppose your team is responsible for creating a module with some kind of Permission so when the system is granted that permission a block of code will be executed, something like if (SecuritySystem.IsGranted( new MyPermission())){ //do something } and then you pass your module to another team or another consumer and he decides to use the “EVIL ONE” property that is exposed by DevExpress.ExpressApp.Security.SecurityBase class is name IsGrantedForNonExistentPermission and can be changed easily as shown in the next image What it does? As its name states inverse the behavior of the SecuritySystem.IsGranted Διαβάστε περισσότερα »...

For this question don’t we all of us spend a lot of time ? But I think it is allowed to use a trick to spend our selves that time. Add to your model to attributes NotifyIcon, MinimizeOnClose. Since I am using Xaf I am going to present that with it but the code should be very similar to any other windows application so here are our attributes NotifyIcon: will add a tray icon for your app at the system tray with a context menu that will allow you to terminate your application and display it when you double click the icon public partial class NotifyIconController : WindowController { public const string NotifyIconAttributeName = "NotifyIcon" ; public NotifyIconController() Διαβάστε περισσότερα »...

I'm trying to find my way into the Silverlight world lately. And one of the most predominant phrases in this world is Model-View-ViewModel pattern or else MVVM. This good old pattern suggests the separation of concerns in the UI tier into the three distinctive layers it's name indicates. I've never dealt with MVVM before and as I said Silverlight is also new to me. Therefore I'm trying to read as much as I can before digging into the code. The most enlightening article I've read so far is Kathleen Dollard's Διαβάστε περισσότερα »...

Suppose that in a WPF application there are some custom User Controls implemented. During development in some windows that use the custom User Control you may find that the designer cannot load them and instead it gives the following error: "Could not create an instance of type YOURCONTROLHERE" This happens because the designer runs the constructor for the User Control whenever it needs to display it in design mode. Within the constructor something throws an exception. Sometimes this does not mean Διαβάστε περισσότερα »...

Pretty silent these days eh? I am working on a big refactoring on DictionaryDifference and have not much time to blog. But have another tip for my Xaf Tips series today maybe not strictly Xaf but is an XPO tip that you can use with your Xaf applications . The Problem Suppose your are a strongly typed fun like me or you want to use linq to query objects inside a transaction. In order linq to be used with XPO DevExpress provides XPQuery<T> class but unfortunately this do not support transactions. So the following test fails var work = new UnitOfWork(); new User(work){UserName = "Sam" }; User firstOrDefault = new XPQuery<User>(work).Where(user => user.UserName == "Sam" ).FirstOrDefault(); Assert.IsNotNull(firstOrDefault); The solution Διαβάστε περισσότερα »...
