Answer 1

Just select only Name and City in dt, so that you can do something like,

        dgv_ClientDetail.DataSource = dt;
        DataGridViewComboBoxColumn dgvCboColumn = new DataGridViewComboBoxColumn();
        dgvCboColumn.Name = "Contacts";
        dgvCboColumn.DataSource = dtContacts; //DataTable that contains contact details
        dgvCboColumn.DisplayMember = "Name";
        dgvCboColumn.ValueMember = "Id";
        dataGridView1.Columns.Add(dgvCboColumn);

EDIT:

        dgv_ClientDetail.DataSource = new DataView(dt)
                                         .ToTable(true, new string[] { "Name", "City" });
        DataGridViewComboBoxColumn dgvCboColumn = new DataGridViewComboBoxColumn();
        dgvCboColumn.Name = "Contacts";
        dgv_ClientDetail.Columns.Add(dgvCboColumn);
        foreach (DataGridViewRow row in dgv_ClientDetail.Rows)
        {
            DataGridViewComboBoxCell cboContacts = (DataGridViewComboBoxCell)
                                                         (row.Cells["Contacts"]);
            cboContacts.DataSource = //Get the contact details of a person,
                                     //using his Name or Id field (row.Cells["Name"]);
            cboContacts.DisplayMember = "Name"; //Name column of contact datasource
            cboContacts.ValueMember = "Id";//Value column of contact datasource
        }

Hope this helps...
