RunTimeError in ASP.Net

Question

I am doing .net application which is in vb.I am getting an runtime error when running in Internet Explorer,but its running in mozilla. Error as following

Error:SysArgumentTypeException:Object of type 'AjaxControlToolKit.Animation.Length Animation' cannot be converted to type ;AjaxControlToolKit.Animation'.Parameter Instance.

Error is getting in MicrosoftAjax.debug.js if(!this.isInstanceOfType(instance)) throw Error.argumentType('instance',ObjectgetType(instance))

What may be the reason for this error.What can i do to resolve this? Can anybody help?

Answer 1

The error indicates, that you are trying to cast a type called Length Animation to a type called Parameter. In VB and VB.NET, the cast is tried implicitly if the types of an assignment doesn't match. Please have a further look at the stack-trace to find the exact line of the error.

PS: I didn't know that there could be spaces in a .NET type name...
