ASP.NET Spell Check control error/compatability on Windows 8.1

[Michael]

Hello,

I am using version 2012.3.1308.40 of the ASP.NET Ajax controls.

When I try loading my application in any browser (Chrome, IE11, etc) on Windows 8.1 64bit, the Spell Check control throws an error, with the following exception:

Message: Unsupported DialogParameters type
Source: Telerik.Web.UI
Stack: at Telerik.Web.Dialogs.DialogParametersSerializer.GetParameterType ...

I was wondering if this version of the ASP.NET Ajax controls is supported on Windows 8.1?

Thank you.

I updated to version 2013.3.1114.40 of the controls, and I still run into the same issue.

The exception is thrown inside of the Render method of the control, specifically this exception:

An exception of type 'System.Reflection.TargetInvocationException' occurred in App_Web_zjnyj3uw.dll but was not handled in user code

The InnerException is still "Unsupported DialogParameters type".

I am attempting to use the control with the Language set to "en" and DictionaryLanguage set to "en-US"

I have resolved this issue, I believe that it may have possibly been caused by the language not being set and passed in to the control due to an issue internal to the application.
