Datagridview SelectionChanged event based on row selection

.net, c#, datagridview, datagridviewrow, visual-studio

Solution

    int curRow = -1;

    private void dgv1_SelectionChanged(object sender, EventArgs e)
    {
        if (dgv1.CurrentRow.Index != curRow)
        {
            curRow = dgvPatientDetail.CurrentRow.Index;        
        }

Problem

I have a DataGridView on a TabPage. When the user clicks on a row, a second DGV appears. Each row is associated with its own DGV filled with data. What I want is for when the user goes from one row to another, the DataGridView changes too. So far I've tried the SelectionChanged event but I don't want the DGV to reload in the event that the user clicks on a separate cell in the same row. Any help would greatly be appreciated. ``` void dgv1_CellClick(object sender, DataGridViewCellEventArgs e) { int rowIndex = dgv1.Rows[e.RowIndex].Index; if (dgv1 == null) return; if (dgv1.Rows[e.RowIndex].Cells[rowIndex].Selected == true); { dgv2.Size = new Size(dgv2.Width + 800, dgv2.Height); dgv2.Location = new Point(0, 500); tp.Controls.Add(dgv2); Console.WriteLine("Row clicked"); } } ``` -Tatiana
