Athugasemd

Microsoft Notepad is used as the text provider for example purposes only. Microsoft Notepad is not guaranteed to support the attribute value being requested.

private void GetMarginTrailingAttribute()
{
    // Start application.
    Process p = Process.Start("Notepad.exe", "text.txt");

    // target --> The root AutomationElement.
    AutomationElement target = AutomationElement.FromHandle(p.MainWindowHandle);

    // Specify the control type we're looking for, in this case 'Document'
    PropertyCondition cond = new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document);

    AutomationElement textProvider = target.FindFirst(TreeScope.Descendants, cond);

    TextPattern textpatternPattern = textProvider.GetCurrentPattern(TextPattern.Pattern) as TextPattern;

    if (textpatternPattern == null)
    {
        Console.WriteLine("Root element does not contain a descendant that supports TextPattern.");
        return;
    }

    Object oAttribute = textpatternPattern.DocumentRange.GetAttributeValue(TextPattern.MarginTrailingAttribute);
    if (oAttribute == TextPattern.MixedAttributeValue)
    {
        Console.WriteLine("Mixed trailing margins.");
    }
    else
    {
        Console.WriteLine(oAttribute.ToString());
    }
}

Remarks

This attribute represents the trailing margin applied to the page(s) associated with the calling text range.

This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in TextPatternIdentifiers.

UI Automation clients get the value of the attribute by calling GetAttributeValue.

Values for this attribute are of type Double. The default value is zero.
