You should declare a private field in the form to store the current index in the list.

You can then increment it when the Next button is pressed.

If the end of the list has then been reached, you could wrap around to the first item, by setting the current index to 0.

Some 'rough and ready' code:

private int currentIndex = -1; // impossible starting value

private void btnNext_Click(object sender, EventArgs e)
{
currentIndex++; // will be zero, when button first clicked
if (currentIndex == list.Count) currentIndex = 0;
// code to display current record
}
