    When working with data there are a number of occasions where you may want to calculate a value for display within a grid.  Did you know you can do this within the RadGridView itself?  It is really quite simple.  To compute a column within the RadGridView you need to set the Expression property of the destination column.  This may be a new column that you are adding to the grid to store the value or you can override the value of an existing column by setting the Expression property.  Below is an example of the syntax to calculate an average across all...

    Making a RadGauge look like a Dial

    I have had several people ask me about whether Telerik offers a dial control.  I thought it might be interesting to try and leverage the RadGauge control to build something that looks like a dial.  Essentially the RadGauge offers all the capabilities you would need, it is just a matter of styling.  I decided to build a kitchen timer application so I could create a dial theme.  I am no artist, but I think my end result turned out pretty well.  The video below will demonstrate how I use Expression Blend to quickly get a 3D (ok, 3Dish, again I...
