MissingMethodException Error...

[tom]

I am using Q1 2009 and follow the Live Examples of ClientBinding.

Unable get the example to work with error:

System.MissingMethodException was unhandled by user code

  Message="No parameterless constructor defined for this object."

  Source="mscorlib"

Re-install .NET 3.5 SP1 frame work does not fix problem.

How can I fix it?

Thank.

Hello tom,

I suggest you review the communications from the following public forum post and migrate to the latest internal build of RadControls for ASP.NET AJAX to address the issue in question.
