So a customer emailed into our office yesterday asking about whether RadChart for Silverlight supported a Step chart type.  Well, while we do have a boatload of chart types already, Step is currently not one of them.  But a Step chart is really just a Line chart with a bit of extra work, right?  With the help of our chart wizard Manol, we were able to show that the LineSeriesDefinition could, in fact, replicate a Step chart.  But that was with setting all points manually and took a bit of thinking to make sure all the steps looked right.  So...

A few weeks ago, someone asked me if the RadChart supported dragging the series items around.

Furthermore it is achieved without writing ANY code in the code behind file of your project. Now let’s get to the job! What will be needed is just one RadGrid and two OpenAccessDataSource controls. The two data source controls will be used to query data from the master and detail tables. In our case we used the Company and Employee tables(one company has many...
