is there any method in data grid view where i show data with select row and also control this with next and previous button
i also done this its work next and previous row but i can get data from data grid view

What I have tried:

mouse click event working well and get the data

private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.RowIndex < dt.Rows.Count && e.RowIndex >= 0)
                webBrowser.DocumentText = dt.Rows[e.RowIndex]["Body"].ToString();
        }

// this is what i want to do but still no getting any data in text box
// in this event how can i apply same thing what i done in mouse click event ? 

private void DataGridView1_CurrentCellChanged(object sender, EventArgs e)
        {
            if (this.dataGridView1.CurrentRow != null)
            {


                textBox2.Text = dataGridView1.CurrentRow.Cells[0].Value.ToString();

                this.pre.Enabled = this.dataGridView1.CurrentRow.Index > 0;
                this.next.Enabled = this.dataGridView1.CurrentRow.Index < this.dataGridView1.Rows.Count - 1;
            }
        }

        private void next_Click(object sender, EventArgs e)
        {
            int next = this.dataGridView1.CurrentRow.Index + 1;
            this.dataGridView1.CurrentCell = this.dataGridView1.Rows[next].Cells[this.dataGridView1.CurrentCell.ColumnIndex];
        }

        private void pre_Click(object sender, EventArgs e)
        {
            int prev = this.dataGridView1.CurrentRow.Index - 1;
            this.dataGridView1.CurrentCell = this.dataGridView1.Rows[prev].Cells[this.dataGridView1.CurrentCell.ColumnIndex];
        }
