Here is a small code snippet to scroll the content in List box. (If the items are more)
In the top, you should add the code
this.listBox1.TopIndex = 0;
After wards, you have to modify the index of the list box slowly.
listBox1.Items.Add(line);
this.listBox1.TopIndex = listBox1.Items.Count - 1;
Check my previous post for the entire piece of code.
