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...

I would like to introduce a new endeavor called "Edge Of Dev". The Edge Of Dev will essentially be me sharing video content that I capture from around the development community.  This may be interviews, presentations, open spaces or other content of interest.  My hope is that the Edge Of Dev will provide an additional resource for relevant technical information to help you stay informed about what is happening in the development community.  The first episode is available on the Edge of Dev website (http://www.edgeofdev.com) so I hope you will take a moment to check it out. This week I am at...

When you start working with OpenAccess, one of the first tasks you're going to face is the need set a connection string to your database. And odds are, the connection string you're going to start with is not going to be the connection string your going to use on your production server. It might not even be the connection string your going to use in your test environment. Point is, you need to be able to store multiple connection strings and easily "cue" OpenAccess to use the correct connection details at runtime. Fortunately, OpenAccess makes this easy.   UNDERSTANDING OPENACCESS CONNECTIONS First things first:...

RadChart comes with a versatile collection of preset themes (Summer, Vista, Office). At times you may wish to use one of the predefined themes but customize its appearance a bit to fit your specific scenario / application and the control provides easy mechanism to achieve the desired effect. RadChart uses the concept of style palettes in order to style the various chart series. There are distinct style palettes for the various series types (Line, Bar, Pie, etc.) and each palette can contain as many style elements as you want -- the first style is applied to the first chart series of...

I won't go into detail about how you could use the maybe monad to save a few lines of code as Daniel Earwicker already blogged about it so you'd better read his post. Basically using the IfNotNull extension method you'll be able to replace lines of code like these: string[] url = SplitUrl(urlString); RecordCompany company = Music.GetCompany("4ad.com");     if (company != null)   {       Band band = company.GetBand("Pixies");       if (band != null)       {           Member member = band.GetMember("David");             if (member != null)               return member.Role;       }   }   return null;    with the following: return Music.GetCompany("4ad.com")...
