Moves to the next item in the list.

public void MoveNext()

Changes the current value of the Position property to the next item in the underlying data source.

The following code example demonstrates the MoveNext, MoveFirst, Current, and Position members. To run this example, paste the code into a form that imports the System.Drawing.Drawing2D namespace and contains a BindingSource named BindingSource1 and a button named button1. Associate the Form1_Load and Form1_Paint methods with the Load and Paint events for the form, and associate the button1_click method with the Click event for button1. Visual Basic users will need to add a reference to System.Data.dll.

void Form1_Load(object sender, EventArgs e)
	// Set the data source to the Brush type and populate
	// BindingSource1 with some brushes.
	BindingSource1.DataSource = typeof(System.Drawing.Brush);
		new TextureBrush(new Bitmap(typeof(Button), "Button.bmp")));
	BindingSource1.Add(new HatchBrush(HatchStyle.Cross, Color.Red));
	BindingSource1.Add(new SolidBrush(Color.Blue));

private void button1_Click(object sender, EventArgs e)
	// If you are not at the end of the list, move to the next item
	// in the BindingSource.
	if (BindingSource1.Position + 1 < BindingSource1.Count)

	// Otherwise, move back to the first item.

	// Force the form to repaint.

void Form1_Paint(object sender, PaintEventArgs e)
	// Get the current item in the BindingSource.
	Brush item = (Brush)BindingSource1.Current;

	// If the current type is a TextureBrush, fill an ellipse.
	if (item.GetType() == typeof(TextureBrush))

	// If the current type is a HatchBrush, fill a triangle.
	else if (item.GetType() == typeof(HatchBrush))
			new Point[] { new Point(0, 0), new Point(0, 200),
                  new Point(200, 0)});

	// Otherwise, fill a rectangle.
			(Brush)BindingSource1.Current, e.ClipRectangle);
