I m not sure.. Is this your problem..

R you accessing the Employee directly.. ??
Like

Gridcustom.DataSource= Employee; // You cannot access this way.

You can access only by the following

Gridcustom.DataSource= EmployeeAccessLayer.Employee;

I think you make the new project class in Main project. this class can call in aspx page with the help of NameSpace Name (like below Myclass).

C#

using System.Configuration;
using System.IO;
using System.Data;
using System.Data.SqlClient;
 
NameSpace myclass
{
public class EmployeeAccessLayer
{
 public class Employee
    {
 
        public int id { get; set; }
        public string name { get; set; }
        public int age { get; set; }
        public string sex { get; set; }
    }
 

}

}

Class call in Aspx page

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using myclass; 

 
public partial class _Default : System.Web.UI.Page
{

EmployeeAccessLayer emp= New EmployeeAccessLayer(); Class call here 
    protected void Page_Load(object sender, EventArgs e)
    {
 
emp.Employee();
        if (!IsPostBack)
        {
 
            int totalrows = 0;
 
            Gridcustom.DataSource= EmployeeAccessLayer  //when i try to access that class here i am unable to do that...

        }
 
    }

made the class static but not working

anurag19289 17-Dec-13 13:57pm

public static class EmployeeAccessLayer
{
public class Employee
{

public int id { get; set; }
public string name { get; set; }
public int age { get; set; }
public string sex { get; set; }
}

Solution 3

Create Namespace can define the Scope of the Defined class which gives an organized access.Already , Joginder has pointed out that .

MyNamespace.MyClass

Just wanted to add that instead of EmployeeAccessLayer defined as a parent class can be the namespace if the intention was to group the Employee related classes.So the accessing of nested classes can also be well avoided.Or else you have to take care of the instantiation of the containing classes residing in the parent class.

Hope this helps you...
