Refreshing datatable binded to a datagridview

I went through a lot of questions and solutions, can't get this to work.
I have a table on my raspberry pi which I an accessing on a windows application, the pi updates the table every second and I need the data grid to refresh itself while allowing the user control over the grid view.
I am getting a cross-thread error with this solution
private void button1_Click(object sender, EventArgs e)
{
BindingSource bs = new BindingSource();
bs.DataSource = GetAccList();//GetAccList returns a datatable
dataGridView1.DataSource = GetAccList();
Loop();
}
private void Loop()
{
backgroundWorker1.RunWorkerAsync(2000);
this.backgroundWorker1.DoWork += new System.ComponentModel.DoWorkEventHandler(this.backgroundWorker1_DoWork);
}
private void Refresh()
{
while (true)
{
dataGridView1.Refresh();
}
}
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
Refresh();
}

You will need to invoke dataGridView1. Look intoControl.Invoke()

Also, look into using async/await rather than background workers if it's easily changable and not part of a bigger platform, can make code a lot cleaner.

You will need to invoke dataGridView1. Look intoControl.Invoke()

Also, look into using async/await rather than background workers if it's easily changable and not part of a bigger platform, can make code a lot cleaner.
