A floating-point value that specifies the vertical scroll position, in device-independent units (1/96th inch per unit).

The value of this property is 0.0 if the text editing control is not configured to support scrolling.
This property has no default value.
An attempt is made to set this property to a negative value.
The following example demonstrates how to read the value of the property.
Private Sub initValues(ByVal sender As Object, ByVal e As EventArgs) myTB1.Text = "ExtentHeight is currently " + myTextBox.ExtentHeight.ToString() myTB2.Text = "ExtentWidth is currently " + myTextBox.ExtentWidth.ToString() myTB3.Text = "HorizontalOffset is currently " + myTextBox.HorizontalOffset.ToString() myTB4.Text = "VerticalOffset is currently " + myTextBox.VerticalOffset.ToString() myTB5.Text = "ViewportHeight is currently " + myTextBox.ViewportHeight.ToString() myTB6.Text = "ViewportWidth is currently " + myTextBox.ViewportWidth.ToString() radiobtn1.IsChecked = True
