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.
Exceptions

Examples
The following example demonstrates how to read the value of the HorizontalOffset property.
private void initValues(object sender, EventArgs e)
{
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;
}
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
Remarks
The horizontal offset is measured from the right of the visible text area if you are working in right-to-left mode; otherwise, it is measured from the left.
