Hi kefah,   
Thanks for using Syncfusion product.   
If you migrate the VS2003 to VS2010, we suspect that your project Syncfusion reference dlls are referring .NetFramework 2.0 key tokens, but your project framework might be in 4.0. So, please follow the below suggestion to resolve this issue,   
Suggestion 1:   
  • Open you project in Notepad.
  • Check whether any key tokens are referring for the Syncfusion dlls. If yes, please remove that key tokens of all Syncfusion assemblies. Please refer the below code example,
Code example   
<Reference Include="Syncfusion.Grid.Windows , Version=, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89, processorArchitecture=MSIL">    
<!--</Change the above code like as below>-->    
<Reference Include="Syncfusion.Grid.Windows”>    

Suggestion 2:   
  • Select all the Syncfusion assemblies from project reference and open the property window (Alt + Enter) for selected assemblies.
  • Change the specific version as false using property window.
  • Now, clean and rebuild your project.
If you are still facing the issue, please provide your project file with issue reproducible state. It will be helpful for us to provide the solution at the earliest.
