Namespace:  System.Windows.Controls.Primitives
Assembly:  PresentationFramework (in PresentationFramework.dll)

public double HorizontalOffset { get; }
You cannot set this property in XAML.

Property Value

Type: System.Double
A floating-point value that specifies the horizontal scroll position, in device-independent units (1/96th inch per unit).
Setting this property causes the text editing control to scroll to the specified horizontal offset. Reading this property returns the current horizontal 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.

ExceptionCondition
ArgumentException

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

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.

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;
}
