Hello dev_here,
I'm following up to see if you still need assistance with the matter.
Hi dev_here,
Can you share the exact error you are getting? Are you changing the datasource when radio button is clicked? Is it possible for you to provide some code or a sample project?
You could refer to this thread for sample use of RefreshBehaviors method - http://ko.infragistics.com/community/forums/t/51856.aspx. Can you specify what error you are getting and if possible share some code?
