DataGridView on Row.Render() throws NullReferenceException

Hi everyone,

I’m using a DataGridView bound with a BindingSource.

We have like 5/6 Clients which updates data, at start we attach every client to an Event to keep everyone updated in real time.

To manage it, we did a function like :

private void Update(){

Grid.BeginUpdate();

//logic to insert on binding

Grid.EndUpdate();

}

When the grid updates (at around 100- 200ms per update) it throws this error:

System.NullReferenceException:
Object reference not set to an instance of an object.

Is there a possible way to handle this error?

Best of regards,
