How to display the before any row

Hi,

I have a datagridview with five records.

ID Name Salary

1 Samira 1.000,00

2 Idia 5.000,00

3 Wassa 2.000,00

4 Sheton 2.300,00

5 Elija 4.000,00

When I want to display the Id number 3 on my textboxes I do this:

private void dgvTest_CellClick(object sender, DataGridViewCellEventArgs e)

{

if (e.RowIndex >= 0)

{

DataGridViewRow row = this.dgvTest.Rows[e.RowIndex];

if (dgvTest != null)

lblID.Text = row.Cells["id"].Value.ToString();

txtName.Text = row.Cells["name"].Value.ToString();

txtSalary.Text = row.Cells["salary"].Value.ToString();

But the problem is how can I display the before one record selected. Mean to show the ID number 2 clicking on ID number 3.

I can click on ID number 5 but I want to be displayed on my textboxes the ID number 4.

Intelligent question!!!

If the ID 1 is selected. The textboxes must display Null data because there is nothing before this datagridview record.

Clarify this : When you click on ID 1 row data then which ID data you want to display at textbox?

EXACTLY what I want.

Datas should be displaying on the same textboxes.

correct me if i understand wrong,

1) for example when you click on ID 3 row then you want to display data of ID 2 row data, am i right?

2) When you click on ID 1 then which ID data you want to display ?
