but when select search button for second time the new row at the end do not appears.

How can I fix this problem? is there better solution to do this?

private void dgvPlannedWoInstruction_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
     var senderId = (DataGridView) sender;
     if (senderId.Columns[e.ColumnIndex] is DataGridViewButtonColumn && e.RowIndex >= 0)
     {
        var frmSearch = new FrmStandardInstructionList();
        frmSearch.ShowDialog();
        if (frmSearch.ucStandardInstructionList1.standardInstructionDto != null)
        {
            senderId.BeginEdit(true);              
            PlannedInstructionDTO p;
            senderId.NotifyCurrentCellDirty(true);
            senderId.BeginEdit(true);
            senderId.CurrentRow.Cells["StandardInstructionCode"].Value = frmSearch.ucStandardInstructionList1.standardInstructionDto.Number;
            senderId.CurrentRow.Cells["StandardInstructionId"].Value = frmSearch.ucStandardInstructionList1.standardInstructionDto.Id;
            senderId.EndEdit();
        }
     }
}

You could refresh the DataSource after it has been updated like:

DataGridView view = new DataGridView();
view.DataSource = somesource;
view.DataSource = null;
view.DataSource = updatedsource;

Sorry I can't post comments, but this should help. See also: How can I refresh c# dataGridView after update ?
