                    GridTrxInvF.CurrentCell = GridTrxInvF[0, iRow + 1];  
                else  
                    GridTrxInvF.CurrentCell = GridTrxInvF[iColumn + 1, iRow];

@ahmed salah , Welcome to Microsoft Q&A, based on my test, I reproduced your problem. It seems that datagirdview will move cursor to the same column in the next row when we use the datagirdview keydown event.

I recommend that you use ProcessCmdKey method to do it and here is a code example you could refer to.

 protected override bool ProcessCmdKey(ref Message msg, Keys keyData)  
        {  
            if (keyData == Keys.Enter)  
            {  
                if (dataGridView1.CurrentRow != null)  
                    dataGridView1.CurrentCell =  
                        dataGridView1  
                        .Rows[Math.Min(dataGridView1.CurrentRow.Index + 1, dataGridView1.Rows.Count - 1)]  
                        .Cells[0];  
            }  
            return base.ProcessCmdKey(ref msg, keyData);  
        }  

Note: Please delete the keydown event to avoid the conflict when we use the above method.

Tested result:

Best Regards,
