    Customizing the Radial RadGauge

    Hello everyone and happy new year. Today I decided to break the lengthy silence on my blog with an example on how to customize the RadGauge. Since there were a couple of requests for custom Radial Gauge, I will present a way to create a semi-circle gauge. That is generally achieved in two steps: Customize the radial scale range Four parameters define the radial scale range: StartAngle, SweepAngle, Radius and Center. The StartAngle and SweepAngle are specified in degrees (0 to 360), starting from the right side of the gauge, going clockwise (note, that positive angle direction is starts from positive X and goes to the positive...

    Comparing Generic Types

        Today I was dealing with the problem of comparing generic types in Silverlight. After researching the problem I found many similar issues for which I couldn't find any straightforward solution on the web. So here we go - a post on the issue how to compare generic types. First, let’s say we have a simple generic class which is composed of two generic properties A and B, and a method that we will later use to compare these two properties. Moreover, I will constraint the class to invoke the constructor of the generic type argument by using where T : new()      public class GenericClass<T> where T : new()       {...

    Encode and Decode URI(Uniform Resource Identifier) using JavaScript

    The current article is taken from https://developer.mozilla.org/ In some scenarios it is useful to encode and decode the URI. For example: To avoid unexpected requests to the server, you should call encodeURIComponent on any user-entered parameters that will be passed as part of a URI. For example, a user could type "Thyme &time=again" for a variable comment. Not using encodeURIComponent on this variable will give comment=Thyme%20&time=again. Note that the ampersand and the equal sign mark a new key and value pair. So instead of having a POST comment key equal to "Thyme &time=again", you have two POST keys, one equal to "Thyme " and another...

    Passing parameters to a UserControl inside RadWindow for Silverlight

    I just wrote a simple application that demonstrates how to databind a treeview to a dummy data source and edit its items in a UserControl, placed in a RadWindow. You could see my other blog posts for examples with web service binding and upgrade the application to suit your needs. To accomplish the requirements, we need to add a property that will contain the edited data item on the UserControl. When the selection in the TreeView changes, we will update that property with the new selection and then open the RadWindow. The UserControl will create a copy of the data item...

    Marketing and Silverlight, configuring cross-domain banners

    I have been part of Telerik’s Silverlight team for almost a year now, and I too well know that our marketing team is just two floors away to say anything bad about marketing.  So I will just say that now having Silverlight 2 in its official version out, marketing mix should adopt one more P in its four P’s concept, Ptechnology. That is why, I will try to explain this topic step by step, so that all marketing guys attracted by the name of this topic can delete the first paragraph and give it to their development teams for consideration....
