Using this to represent rows of data...

and using this to represent cells of data...
namespace LyndWorld.LiveWire.SilverlightUI.Entities
{
public class LiveWireDataCell
{
private object _value;
private string _referenceUrl;
public LiveWireDataCell(object pValue)
{
_value = pValue;
}
public LiveWireDataCell(object pValue, string pReferenceUrl)
{
_value = pValue;
_referenceUrl = pReferenceUrl;
}
public object Value { get; set; }
public string ReferenceUrl { get; set; }
}
}
The grid doesnt know to call the Value property of the LiveWireDataCell object to get its display value. See the code below for how I am building and binding.

Hi,
Vlad

I'm not sure I understand the problem. Do you have this working with standard Silverlight DataGrid and not working with RadGridView?
