RadListBox not found - Telerik.Windows.Control

[JoLynn]

I have an older SL application that was using Q1 2013 version.  When I wanted to run the project to debug an issue, it doesnt run, complaining that RadListbox not found.  Is it not part of Telerik.Windows.Control?

I have this on the top:

           xmlns:local="clr-namespace:Slb.FluidUtilities.Web.Assets"

and xaml looks like:
<telerik:RadListBox ItemsSource=....> - line with error "Cannot resolve symbol RadListBox"

Hi JoLynn,

Did you try to clean/rebuild the project/solution and delete the bin/obj folders - the issue could be related to version mismatch between Telerik binaries? Please, check also if you have referenced all the needed binaries and if they are all with the same version.

Hopes this helps.
