DataGridView Row Enter and Right Click event

C#3.5

I have a data grid view in a form, where I have done some work such as getting specific cell value and some other validation in DataGridView.RowEnter event. This event is fired twice while the form is loading. After that, each time a Row is selected with Left Mouse Button, this event fires.

But I have done some code in the MouseDown event to select the row when I click Right Mouse Button. But the problem is this time RowEnter event doesn't fire and I can't get the specific cell value of the selected row. It just returns the previous values it has.

this is code block of RowEnter event.

private void dgvNewTestRequests_RowEnter(object sender, DataGridViewCellEventArgs e)
        {

            String testStatus = "";
            String test = "";
            //String patientName = "";
            ResetAll();
            patientID = Convert.ToInt32(dgvNewTestRequests.Rows[e.RowIndex].Cells[0].Value.ToString());
            patientName = dgvNewTestRequests.Rows[e.RowIndex].Cells[1].Value.ToString();
            testStatus = dgvNewTestRequests.Rows[e.RowIndex].Cells[8].Value.ToString();

            if (testStatus == "Incomplete")
            {
                markAsCompletedToolStripMenuItem.Enabled = true;
                markAsIncompleteToolStripMenuItem.Enabled = false;
                //ChangeRowColor();
            }
            else
            {
                markAsCompletedToolStripMenuItem.Enabled = false;
                markAsIncompleteToolStripMenuItem.Enabled = true;
                //ChangeRowColor();
            }

            for (int i = 4; i <= 7; i++)
            {
                test = dgvNewTestRequests.Rows[e.RowIndex].Cells[i].Value.ToString();
                if (test == "Blood Test")
                    bloodTestInventoryToolStripMenuItem.Enabled = true;

                if (test == "Urine Test")
                    urineTestInventoryToolStripMenuItem.Enabled = true;
                if (test == "X-Ray")
                    xRayInventoryToolStripMenuItem.Enabled = true;
                if (test == "Ultrasonography")
                    ultrasonographyInventoryToolStripMenuItem.Enabled = true;
            }
        }

I want to do the same thing when i right clicked the mouse button to select the row.
