    Making a Step chart in RadChart for Silverlight and WPF

    October 02, 2009 Share
    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...

    Sorting, Filtering, Grouping and Aggregating on all CPU cores using RadGridView for WPF and PLINQ

    September 23, 2009 Share
    As some of you may already know the Q2 release of RadGridView for WPF ships with a brand new “data engine” entirely based on LINQ. This means that all data operations including sorting, filtering, grouping, aggregating and paging will be pushed down to the IQueryProvider when RadGridView is bound to an IQueryable. For example if you are using LinqToSql, LinqToEntities or OpenAccess ORM all gird operations are executed on the SQL server using the magic of LINQ providers. Staying on the cutting edge I decide to try out PLINQ (Parallel LINQ) and enable RadGridView to execute its data operations on all available CPU cores. PLINQ...

    Mark working hours and days in different colors with RadScheduler for Silverlight

    We received a couple of questions on how some of the days and hours in the different views of RadScheduler can be customized. The answer of this question is in the attached application illustrating how working hours and days can be  marked in orange.  The solution includes 3 easy steps : Create a custom theme using the default RadScheduler' theme.

    RadDrag&Drop with a Canvas twist

    August 18, 2009 Share
    A week or so ago I was giving a small presentation and one of the people in the audience had a great question.  They had this old configuration section on their website for laying out something or other that had a lot of different options which could be dragged and dropped using some client-side javascript, but they are looking to move on up to Silverlight and the RadDragAndDropManager seemed to be the perfect candidate for the job.  The only issue with that is the only examples we have online show moving items to and from collections, but in their case...
