may help you . In the SelectedIndexChanged event of your Regions listbox, get the selected region then use that in your GetDivisionsInRegion method and populate the Divisions listbox with the result.
code :
private void Regions_SelectedIndexChanged(object sender, System.EventArgs e)
{
   // Get the currently selected item in the ListBox. 
   string region = Regions.SelectedItem.ToString();

   // Find the divisions in the region
   IEnumerable<string> divisions = GetDivisionsInRegion(region);

   //set as this as the new data source for your Divisions listbox
   Divisions.DataSource = divisions;
}

help you fix your problem so if you want to export your source, dont refresh it, filter it. BindingSource has a .Filter method which will help you. change your event to this. done!
code :
 private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    BindingSource bindSource = new BindingSource();
    bindSource.DataSource = yourOrginalSource;
    dataGridView1.DataSource = bindSource;
    //set your bind source filter
    string myFilter = "GroupId = " + listBox1.SelectedIndex;
    source.Filter = myFilter;
}
