Answer 1

Declare Form1's DGV as Public instead of private and do the following in Form2 :

1. Declare the following variable :

   System.Windows.Forms.Form f = System.Windows.Forms.Application.OpenForms["Form1"];.

2. Do the Following changes in your program:

    private void button1_Click (object sender, EventArgs e)      
    {
   
    try
     {
       if (dataGridView1.RowCount != 0)
       {
   
           foreach (DataGridViewRow row in dataGridView1.SelectedRows)
           {                                       
               ((Form1)f).dataGridView1.Rows.Add(row);                    
           }
   
         }
       else
       {
           MessageBox.Show("There is no data to export, please verify..!", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
       }
   }
   catch { }   }
