acces textbox from another form

hi :) you told me earlier how to acces a control from another form, and i have this code:

hy again...i understand the changes you've made, but still doesn't work properly..
for example in the datagrid i have 

1
2
3
4
5

if my selected row is 3, click next and record no 4 is shown, but when i click next again doesn't show 5, it's still 4.

The problem is that you're not changing the selected row in the DGV after each click of the picturebox and so it always starts at the originally selected row.

Try this instead:

        private void pictureBox1_Click(object sender, EventArgs e)
        {
            System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection();
            conn.ConnectionString = "..";
            conn.Open();

            Acasa main = (Acasa)Application.OpenForms["Acasa"];
            DataGridView dgv = main.clientGridView;
            int i = dgv.CurrentRow.Index;
            int maxRows = dgv.Rows.Count;

            if (i != maxRows - 1)
            {
                i++;

                textBox1.Text = dgv.Rows[i].Cells[0].Value.ToString();
                textBox2.Text = dgv.Rows[i].Cells[1].Value.ToString();
                textBox3.Text = dgv.Rows[i].Cells[2].Value.ToString();
                textBox4.Text = dgv.Rows[i].Cells[3].Value.ToString();
                textBox5.Text = dgv.Rows[i].Cells[4].Value.ToString();

                dgv.Rows[i].Selected = true;
                dgv.Rows[i -1].Selected = false; // make sure only a single row is selected
            }
            else
            {
                MessageBox.Show("..");
            }

            conn.Close(); // move this to the end so you always close the connection
        }

another problem..i have a form which shows in some textboxes, the selected row in the dgv, and also i added some picturebox for the next and previous record. i don't know what's wrong..it shows the next record only at the first click, then stops. Here's the code:


i really appreciate your help..
