using System.Data;
using System.Windows.Forms;
namespace Notification
{
public partial class Form1 : Form
{
public DataTable dtData = new DataTable();
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
dtData.Columns.Add("CID", typeof(int));
dtData.Columns.Add("CNAME", typeof(string));
dtData.Columns.Add("CPHONE", typeof(string));
dataGridView1.DataSource = dtData;
}
private void button1_Click(object sender, EventArgs e)
{
Form2 obj = new Form2();
obj.ShowDialog();
if (obj.dataGridView1.SelectedRows.Count > 0)
{
foreach (DataGridViewRow row in obj.dataGridView1.SelectedRows)
{
dtData.ImportRow(((DataTable)obj.dataGridView1.DataSource).Rows[row.Index]);

dtData.Rows.Add(2, "ABC", "6985458789");
dtData.Rows.Add(3, "XYZ", "9236598480");
