TextPattern.RangeFromPoint Method

Returns the degenerate (empty) text range nearest to the specified screen coordinates.

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

public TextPatternRange RangeFromPoint(
	Point screenLocation
)

Parameters

screenLocation
Type: System.Windows.Point
The location in screen coordinates.

Return Value

Type: System.Windows.Automation.Text.TextPatternRange
A degenerate range nearest the specified location. Null is never returned.

ExceptionCondition
ArgumentException

A given point is outside the AutomationElement associated with the text pattern.

A text range that wraps a child object is returned if the screen coordinates are within the coordinates of an image, hyperlink, Microsoft Excel spreadsheet, or other embedded object.

Because hidden text is not ignored by RangeFromPoint, a degenerate range from the visible text closest to the given point is returned.

    return targetTextPattern.RangeFromPoint(
        _root.Current.BoundingRectangle.TopLeft);
