how can i fetch data from one datagridview to another datagridview in c#

//Its Working in Cell Double Click 

void dataGridView1_CellBeginEdit(object sender,DataGridViewCellCancelEventArgs e)
 {
   DataTable dtGrid1=(DataTable)DataGridView1.DataSource;  

   string sId=DataGridView1.Rows[e.RowIndex].Cells["Id"].Value.ToString();
  //Here 'Id' is Filter Column (Assume)
  DataRow[] drFilter=dtGrid1.Select("Id="'+sId+'"");
  DataTable dtData=new DataTable();
  dtData=dtGrid1.Clone();
  foreach(DataRow dr in drFilter)
    { 
     dtData.ImportRow(dr);
    }
   if(dtOutput.Columns.Count==0)
    {
     dtOutput=dtGrid1.Clone();
    } 
   dtOutput.Merge(dtData);
   DataGridView2.DataSource=dtOutput.Copy();
}

datagridview1.CellDoubleClick+=new DataGridViewCellEventHandler(datagridview1_CellDoubleClick);

private void datagridview1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
        {
                string cellValue= dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();
              //create datasource base on your cellvalue and assign that datasource to datagridview2

        }
