asp.net error CS1061

Question

hi

 I am getting the following error

Description: An error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1061: 'ASP.modules_transportation_configuration_aspx' does not contain a definition for 'ddlReportRoles_SelectedIndexChanged' and no extension method 'ddlReportRoles_SelectedIndexChanged' accepting a first argument of type 'ASP.modules_transportation_configuration_aspx' could be found (are you missing a using directive or an assembly reference?)


I have removed drop drown and its associated method and again created them.....even though i am getting the same error..
