    I have created a basic RadGridView with one of the bindable values being a double. When populating the collection I just create a random double that I round to 2 decimal values. This shows up in the GridView perfectly. But when I select the filter for this column the values are erroneous to what should be displayed. So say I have a row value of 39.02, then the filter option for this is 39.0200004577637. See attach file.

    Why is it doing this ?

    Cheers ... Rob.

    Hello Rob,

    Indeed, your observations are right.

    This is actually a known issue with the decimal values displayed in the stock Silverlight ListBox that is used inside the FilteringControl for displaying DistinctValues. 

    What you can do to avoid such inconvenience is to define a StringFormat for the Binding, or a DataFormatString for the column (for example DataFormatString="{}{0:N2}").
