As people become more aware of the fantastic things you can do with Silverlight, they’ve also realized one of the downsides of this can be increased XAP size.  The default way that Silverlight handles a XAP is to include all the required assemblies into that single compressed file.  This isn’t that bad when you’re working with a barebones Silverlight project, but once you start adding in different controls or 3rd party assemblies you are increasing your XAP size quite a bit in some cases.  And as we all know, a larger XAP leads to longer load times, and although people have...

    The feedback about our new version of CoverFlow for Silverlight has been great! Thank you guys for pointing out all these small issues and problems that had to be polished since we introduced a new beta CoverFlow for Silverlight 3 back in September. After the core functionality of the control is successfully integrated in our Silverlight 3 suite, we are now able to start developing new features that every grown-up CoverFlow control should possess :) Vertical Orientation     Both in our forum and support system we have received numerous requests for vertical orientation of the CoverFlow control. That is why, with our 2009...

Sometimes when using a Docking control and implementing complex UI with it we need to add some custom rules about allowing some panes to be docked in some parts of the application and to disallow them to dock to other parts. As this behavior is quite complex itself, we’ve decided to enable some scenarios to be available in XAML in a declarative way (the more static scenarios) and some scenarios to be available only through the code-behind.   In this post I will guide you through some simple steps that will show you how you could use both approaches. First of all...

Using FixedDocument, DocumentViewer and PrintDialog you can easily create your own print and/or print preview for RadGridView for WPF. I’ve made two extension methods Print() and PrintPreview() to illustrate how to turn the grid into a print friendly document in few lines of code: … public static void PrintPreview(this GridViewDataControl source) { var window = new Window() { Title = "Print Preview", Content = new DocumentViewer() ...

With the introduction of LINQ the concept of querying data became a first-class language construct in C# and Visual Basic.  LINQ enables to you write type-safe queries which are checked during compile-time. While type-safe queries are fine for certain situations, there might be cases where you want to construct a query on the fly, at runtime, based on certain selections made by the user. This is usually done using a string-based representation of the query. How can this be achieved via LINQ?   The LINQ team at Microsoft provides the Dynamic Query Library which extends the core LINQ API with capability to use...
