TextPatternRange.MoveEndpointByRange Method

Moves one endpoint of a text range to the specified endpoint of a second text range.

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

public void MoveEndpointByRange(
	TextPatternRangeEndpoint endpoint,
	TextPatternRange targetRange,
	TextPatternRangeEndpoint targetEndpoint
)

Parameters

endpoint
Type: System.Windows.Automation.Text.TextPatternRangeEndpoint
The endpoint to move.
targetRange
Type: System.Windows.Automation.Text.TextPatternRange
Another range from the same text provider.
targetEndpoint
Type: System.Windows.Automation.Text.TextPatternRangeEndpoint
An endpoint on the other range.

If the endpoint being moved crosses the other endpoint of the same text range then that other endpoint is moved also, resulting in a degenerate range and ensuring the correct ordering of the endpoints (that is, Start is always less than or equal to End).


 private void MoveEndpointByRangeFromSelection(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;
    }
    TextPatternRange[] currentSelection = textpatternPattern.GetSelection();
    TextPatternRange[] currentVisibleRanges = textpatternPattern.GetVisibleRanges();

    currentSelection[0].MoveEndpointByRange(
        TextPatternRangeEndpoint.Start,
        currentVisibleRanges[0], 
        TextPatternRangeEndpoint.Start);
}



Private Sub MoveEndpointByRangeFromSelection(ByVal target As AutomationElement)
    ' Specify the control type we're looking for, in this case 'Document'
    Dim cond As PropertyCondition = New PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Document)

    ' target --> The root AutomationElement.
    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 currentSelection As TextPatternRange() = textpatternPattern.GetSelection()
    Dim currentVisibleRanges As TextPatternRange() = textpatternPattern.GetVisibleRanges()
    currentSelection(0).MoveEndpointByRange(TextPatternRangeEndpoint.Start, _
                                     currentVisibleRanges(0), _
                                     TextPatternRangeEndpoint.Start)
End Sub
