You need to use database..Do you have any concept about that or do you like to use it?You can also use files instead of database.It's up to you what you will prefer?

Hi,
Sore your details in the datatable and pass that to the second form. For this you need to use a global class file to get and set the values of a DataTable.
Class1.cs

C#

class Class1
{
    static DataTable dt=new DataTable();
    public static DataTable GetData()
    {
        return dt;
    }

    public static void SetData(DataTable dt1)
    {
        dt = dt1;
    }
}

Form1:

C#

private void button1_Click(object sender, EventArgs e)
{
    DataTable dt = new DataTable();
    DataColumn dc = new DataColumn("values");
    dt.Columns.Add(dc);
    dt.Rows.Add("A");
    dt.Rows.Add("B");
    dt.Rows.Add("C");
    Class1.SetData(dt);
}
private void button2_Click(object sender, EventArgs e)
{
    Form2 f = new Form2();
    f.Show();
}

Form2:

C#

private void Form2_Load(object sender, EventArgs e)
{
    DataTable dt = Class1.GetData();
    dataGridView1.DataSource = dt;
}

There are many ways to this.
1. Create a class(object, say Emp) to store all the data you need and modify your second form construction method to include the class object; possibly a List<emp> as you have 5 employees. Also create private members to hold this.

C#

public Form2(List<emp> empList)
        {
            this.EmpList = empList;
            InitializeComponent();
        }

And when you are ready to call Form2, include the argument to construction as your list
2.Here you store all your List<emp> on Form1 as Public property as:

C#

private List<emp> _empList;
        public List<emp> EmpList
        {
            get { return _empList; }
            set { _empList = value; }
        }

Make the second form's parent as Form1 when you ready to view Form2 as :

C#

using (Form2 f2 = new Form2())
            {
                f2.Owner = this;
                f2.ShowDialog();
            }

and on Form2 can be set as(note: this is the entire code for Form2,just to demonstrate):

C#

public partial class Form2 
    {
       Form1 FormOwner;
       private bool[] check = new bool[100];
       private List<emp> EmpList;
       public Form2
        {
            InitializeComponent();
        }
        
        private void Form2_Load(object sender, EventArgs e)
        {

            this.FormOwner = (Form1)this.Owner;
            this.EmpList = FormOwner.EmpList;
      
        }
