Solution 1

The following code will copy each row from one grid to another.

C#

foreach (DataRow row in dataTable1.Rows)
{
    dataTable2.Rows.Add(row.ItemArray);
}

If you want to copy some specific columns use a if statment while copying to the other grid. So it becomes:

C#

foreach (DataRow row in dataTable1.Rows)
{
  if(Condition)
  {
     dataTable2.Rows.Add(row.ItemArray);
  }
}

Good luck,
OI

it throws this exception for the first case you send me...

An unhandled exception of type 'System.InvalidCastException' occurred in aaaa.exe

Additional information: Unable to cast object of type 'System.Windows.Forms.DataGridViewRow' to type 'System.Data.DataRow'.

Please change the DataRow to DataGridViewRow/GridViewRow.

you mean this:
private void button1_Click(object sender, EventArgs e)
{

foreach (DataGridViewRow row in table1DataGridView.Rows)
{
copyDataGridView.Rows.Add(row.ItemArray);
}
}
????
because its still throw the same exception!
