Hey try this. Form1.cs using System; 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.AcceptChanges(); } dataGridView1.DataSource = dtData; } } } Form2.cs using System; using System.Data; using System.Windows.Forms; namespace Notification { public partial class Form2 : Form { public DataTable dtData = new DataTable(); public Form2() { InitializeComponent(); } private void Form2_Load( object sender, EventArgs e) { dtData.Columns.Add( "CID" , typeof ( int )); dtData.Columns.Add( "CNAME" , typeof ( string )); dtData.Columns.Add( "CPHONE" , typeof ( string )); dtData.Rows.Add(1, "Amit" , "9632587415" ); dtData.Rows.Add(2, "ABC" , "6985458789" ); dtData.Rows.Add(3, "XYZ" , "9236598480" ); dtData.Rows.Add(4, "DEF" , "8956471259" ); dataGridView1.DataSource = dtData; } private void button1_Click( object sender, EventArgs e) { this .Close(); } } }
