I have two tab pages on winforms. In tab2 data is fetched in a datagridview from a database. In tab1, I've a combobox [sales analyse]which makes a user to select an option. I now want to get access to tab2 from tab1 on combobox selection, displaying me a regional sales information from the data in tab2 datagrid. Is it possible? I don't really know where to start.

C#

private void cb1_SelectedIndexChanged(object sender, EventArgs e) 
{ 
if (cbAnalyse.SelectedIndex == cb1.FindStringExact("Sales anylse")) 
  { 


  }
}

tab1 image
[^]

tab2 image
[^]

ExAMPLE:
In my DVG in the column sales13, the values for north are 2x 800. So the txtBox for north in tab1 should display 1600 and so for the rest.

EXPECTION:
1. Select an option in combobox
2. Go through the DGV using a where function or ???
3. Display results in the appropriate textbox fields

        dataGridView1.Columns.Add("Col2","Result");
        string[] newstring=new string[]{"North","333"};

        dataGridView1.Rows.Add(newstring);
        newstring = new string[] { "East", "444" };
        dataGridView1.Rows.Add(newstring);
        newstring = new string[] { "Northeast", "555" };

            {
                if (dr.Cells[0].Value.ToString() == "North")
                {
                    textBox1.Text = dr.Cells[1].Value.ToString();
