Answer 1

In YourForm.Designer.cs look for string gridView = new DataGridView() and replace it with

gridView = new SafeDataGridView()

private SafeDataGridView portos_online;

portos_online = new SafeDataGridView();

I hope this will solve your problem. Have a nice day!

Same question here. Use Invoke method

if (gridView.InvokeRequired)
    gridView.Invoke(new MethodInvoker(() => gridView.DataSource = YOUR_DATASOURCE));
else
    gridView.DataSource = YOUR_DATASOURCE;
