casting

I have a simpleAsp.net page which I make it Ajaxable. everything works fine but I face with a problem whenever a specific method calls.

Actually the Browser tell me that

  Sys.WebForms.PageRequestManagerServerErrorException: Unable to cast object of type 'System.Web.UI.LiteralControl' to type 'System.Web.UI.WebControls.WebControl'.

I do not know how to resolve it. Any help appriciates.
