grid sorting/edit error when using partial class property

[J]

Error:
Sys.WebForms.PageRequestsManagerServerErrorException: Cannot find column ColumnName

I have two partial classes:

public partial class Person { public stirng FirstName {get;set;} } //this is generated by SubSonic 2.1
public partial class Person { public stirng LastName {get;set;} } //this is hand written

1.
When i bind Person collection to telerik grid and click to sort on LastName, i get the above error. but it works fine with FirstName column.
My project was using .NET 2.0 (VS2005) and it seemed to be working fine. Since I upgraded to .NET 3.5 all sorts issues all came up. This is just one of the issues.

2.
I also noticed paging isn't working correctly.

3.
GridDropDownColumn also stopped working with Edit command. seems the drop down can not be bind because missing column name from the class.

Is this a known bug with Telerik controls?
do i need to upgrade telerik? I am using telerik.web.ui.dll 2008.1.415.20
with vs2008, .net 3.5, asp.net application project

thanks!

Hello J,

It seems that you are using rather an old version of RadControls for ASP.NET AJAX (Q1 2008). Does migrating to the latest release 2008.3.1314 (Q3 2008 SP2) following the steps from this KB article addresses the issues you are facing? You can use the following online demos of the product for further reference:
