}

Shouldn't it be? 

and why not do this...

    private bool SiteLevelCustomAuthenticationMethod(string UserName, string Password)
    {
        bool boolReturnValue = false;
        string strConnection = "Server=.;Initial Catalog=Doctors;Integrated Security=True";
        SqlConnection Connection = new SqlConnection(strConnection);
        String strSQL = "Select username,password From users Where UserName=@Username and Cast(Password as binary)=Cast(@Password as binary)";
        SqlCommand command = new SqlCommand(strSQL, Connection);
        command.Parameters.Add("@UserName", SqlDbType.VarChar).value = UserName;
        command.Parameters.Add("@Password ", SqlDbType.VarChar).value = Password;
        SqlDataReader Dr;
        Connection.Open();
        Dr = command.ExecuteReader();
        if (Dr.HasRows()){
             boolReturnValue = true;
        }
        Dr.Close();
        Dr.Dispose();
        return boolReturnValue
    }

Hi venkatesham05

I guess you mean the authentication section in web.config, for example

 <authentication mode="Forms"/>
