Not clear...Write your question in simple way and in proper english. I really couldn't understand what you're trying to say after reading 5-6 minutes.

Hi
Try this code..

C#

private void Form1_Load(object sender, EventArgs e)
       {

           DataTable dt = new DataTable();
           dt.Columns.Add("Name", typeof(string));
           dt.Columns.Add("ID", typeof(int));
           dt.Rows.Add("aaaa", 1);
           dt.Rows.Add("bbbb", 2);
           dt.Rows.Add("cccc", 3);
           dt.Rows.Add("ddd", 4);
           dt.Rows.Add("eeee", 5);


           comboBox1.DataSource = dt.DefaultView;
           comboBox1.ValueMember = "ID";
           comboBox1.DisplayMember = "Name";



       }

       private void button1_Click(object sender, EventArgs e)
       {
           string name = ((DataRowView)comboBox1.Items[comboBox1.SelectedIndex]).Row["Name"]+"";
           int id = (int) ((DataRowView)comboBox1.Items[comboBox1.SelectedIndex]).Row["ID"];

       }
