Examples

Note
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 GetUnderlineColorAttribute()
{
// 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.UnderlineColorAttribute);
if (oAttribute == TextPattern.MixedAttributeValue)
{
Console.WriteLine("Mixed underline colors.");
}
else
{
Console.WriteLine(oAttribute.ToString());
}
}
Private Sub GetUnderlineColorAttribute()
' Start application.
Dim p As Process = Process.Start("Notepad.exe", "text.txt")
' target --> The root AutomationElement.
Dim target As AutomationElement = AutomationElement.FromHandle(p.MainWindowHandle)
' Specify the control type we're looking for, in this case 'Document'
Dim cond As PropertyCondition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document)
Dim textProvider As AutomationElement = target.FindFirst(TreeScope.Descendants, cond)
Dim textpatternPattern As TextPattern = CType(textProvider.GetCurrentPattern(TextPattern.Pattern), TextPattern)
If (textpatternPattern Is Nothing) Then
Console.WriteLine("Root element does not contain a descendant that supports TextPattern.")
Return
End If
Dim oAttribute As Object = textpatternPattern.DocumentRange.GetAttributeValue(TextPattern.UnderlineColorAttribute)
If (oAttribute = TextPattern.MixedAttributeValue) Then
Console.WriteLine("Mixed underline colors.")
Else
Console.WriteLine(oAttribute.ToString())
End If
End Sub
Remarks
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.
