TextPatternRange.Clone Method ()

 

Retrieves a new TextPatternRange identical to the original TextPatternRange and inheriting all properties of the original.

Namespace:   System.Windows.Automation.Text
Assembly:  UIAutomationClient (in UIAutomationClient.dll)

public TextPatternRange Clone()

Return Value

Type: System.Windows.Automation.Text.TextPatternRange

The new text range. A null reference (Nothing in Microsoft Visual Basic .NET) is never returned.

Alternatively, create a new DocumentRange from the TextPattern and move the two endpoints to correspond with the endpoints of the original text range.

The new range can be manipulated independently from the original.

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

    // target --> The root AutomationElement.
    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 null;
    }
    TextPatternRange[] currentSelection = textpatternPattern.GetSelection();
    return currentSelection[0].Clone();
}
