Property Value

Setting this property causes the text editing control to scroll to the specified vertical offset. Reading this property returns the current vertical offset.

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

An attempt is made to set this property to a negative value.

Examples

The following example demonstrates how to read the value of the VerticalOffset 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
