Hi zenox,

>potentialInvestorDataGridView.DataBindings.Add("DataSource", bindingSource, "PotentialInvestors");

It is not clear to me why you use simple binding for a list and DataGridView? What you need to do is using complex binding. Please look at the following code.
public partial class Form1 : Form
{
private BindingList<Company> compList = new BindingList<Company>();

public Form1()
{
InitializeComponent();
compList.Add(new Company(1, "Microsoft"));
compList.Add(new Company(2, "Google"));

dataGridView1.DataSource = compList;
}

private void button1_Click(object sender, EventArgs e)
{
compList.Add(new Company(3, "IBM"));
}
}

public struct Company
{
private int companyID;
public int CompanyID
{
get { return companyID; }
set { companyID = value; }
}

private string companyName;
public string CompanyName
{
get { return companyName; }
set { companyName = value; }
}

public Company(int id, string name)
{
this.companyID = id;
this.companyName = name;
}
}
First I need to create a type (company type) with CompanyID and CompanyName. Then I call BindingList.Add method to add new items. You can see I set the DataSource property of DataGridView to bind it to compList.

When I click button1, I added another item into the compList, it displayed on the DataGridView immediately.

Hope this helps you. If I misunderstood you, please feel free to tell me.

Sincerely,
Kira Qian
