    Master/Detail with RadGridView for WPF using ObjectDataProvider and ADO.NET Entities

    In my previous post, I showed how to instantiate LINQ to SQL DataContext using ObjectDataProvider in WPF. With ADO.NET Entities you can do something similar: <Grid.Resources> <ObjectDataProvider x:Key="customers" ObjectType="{x:Type local:NorthwindEntities}" MethodName="get_Customers"> </ObjectDataProvider> <ObjectDataProvider x:Key="orders" ObjectType="{x:Type local:NorthwindEntities}"...

    RadComboBox and ASP.NET AJAX 4.0 Preview &ndash; using client-side templates and webservice load on demand

    Edit: The following content applies to ASP.NET Ajax 4.0 Preview 4. Download the project that uses the latest MS Ajax 4.0 Preview 6 from Here Many of you have asked us, the ASP.NET support officers, whether RadComboBox supports templates when bound to WebService. Using the latest official .NET Framework (3.5) the answer was ‘no’. Fortunately, this is possible with the client-side templates introduced in the next version of the .NET Framework – 4.0. Currently it is in a Preview stage and you can find its roadmap here.  We have already demonstrated how to use the new client-side templates in RadTreeView and RadGrid.

    Encode and Decode strings using JavaScript

    In order for a string to be read from all computers sometimes it is useful to encode and decode it. This can be easily achieved using the JavaScript built-in escape() and unescape() methods. Both the escape() and the unescape() methods have the same argument – the string which will be escaped or unescaped. The escape() method returns a string value (in Unicode format) that represents the encoded contents of the function argument. All spaces, punctuation, accented characters, and any other non-ASCII characters are replaced with %xx encoding, where xx is equivalent to the hexadecimal number representing the character. For example, a space is returned as "%20". Additionally, having...

    BDD. At first I was afraid, I was petrified.

    Yes, seriously, my first reaction to a post in which I noticed BDD-kinda-tests was something like "whoa, interesting naming convention for test method names, and all these underscores...". After that I came upon several other blog posts containing BDD tests and I still didn't get the idea. Then I read Dan North's post introducing the idea of Behavior Driven Development and I finally started catching the point. But catching the point at that time was not like "well, it's worth it and I'll try it" but rather like "ok, it's a TDD variation with some funky new lingo, so... ok". I could abandon...

    Implementing the RadNumericUpDown for WPF

    I am sure that you are wondering why I would spend time blogging about implementing a control as simple as the RadNumericUpDown for WPF.  After all this is not a complex control and if you have done any client development you have probably used a NumericUpDown in the past.  Well, this is not the same control and it does have some nice features that you may not be aware are available.  I thought it might be nice to demonstrate some of these features. So most likely you have used the WinForms version of NumericUpDown and were limited to only a few...

    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...
