C# - how do I refresh DataGridView after removing rows

Question

In my code I need to remove rows from the DataGridView after a recurring interval, and so I call the following function when a timer expires:

private void removeRows(DataGridView dgv) {

    foreach (DataGridViewRow row in dgv.Rows)
    {
        // if some condition holds
        dgv.Remove(row);                
    }
    dgv.Refresh();

}

I know the rows are successfully deleted from the DataGridView, though they still remains in the display for whatever reason. Any tips on what I might be doing wrong?

Don't you need to rebind the data grid?

dgrv.Datasource = [whatever data source];
dgrv.DataBind();

?
