Compiler Error

Jul 13 2015 6:57 AM
how to solved bellow maintain error
 
Compiler Error Message: CS1061: 'ASP.empdetailsfromdb_aspx' does not contain a definition for 'GridView1_SelectedIndexChanged' and no extension method 'GridView1_SelectedIndexChanged' accepting a first argument of type 'ASP.empdetailsfromdb_aspx' could be found (are you missing a using directive or an assembly reference?)
 
here is my design code
