RAD Chart Creates Problems with DLL updates.

[Venkata Nagendra Rao]

i am getting an error while compilation The tag 'RadChart' does not exist in XML namespace 'clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Charting' after updating to a different version of DLL. in the page where i am getting error.I am able to add the same RadChart in the same page but during compilation it just shows above message. If it will not work in different versions of RAD then it should show a relavant message. This small error will cause our UAT to break down. Isnt it necessary for the RAD DLL's to furnish a proper error message?? We have changed from new DLL's to Old DLL's of RAD and the change is not even with Major version and is with minor version.

2010.2.1105.1030 - New

2010.1.309.1030  -  Old version.

Hi Venkata Nagendra Rao,

Please check whether the Data, Controls and Charting dll-s are included. If you problem still exists please send us a small runnable project where your problem can be reproduced.

I was having the exact same problem as mentioned in this thread.  After attempting to create an instance of the RadChart class in code behind, I got a more helpful error message, which told me that one of the assemblies that Telerik.Windows.Controls.Charting is dependent on was an earlier version.  Here is the exact message:

Assembly 'Telerik.Windows.Controls.Charting, Version=2011.2.1023.1040, Culture=neutral, PublicKeyToken=d3625f8bf04286d7'
uses 'Telerik.Windows.Controls, Version=2011.2.1023.1040, Culture=neutral, PublicKeyToken=d3625f8bf04286d7'
which has a higher version than referenced assembly
'Telerik.Windows.Controls, Version=2011.2.727.1040, Culture=neutral, PublicKeyToken=d3625f8bf04286d7' 



Ensuring that all of the assemblies were the same version fixed my problem.
