속성 값

A floating-point value that specifies the horizontal size of the visible content area, 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.

The following example demonstrates how to read the value of the ExtentWidth 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;
}
