TextPointer.IsAtLineStartPosition Property

Gets a value that indicates whether the current position is at the beginning of a line.

Namespace:  System.Windows.Documents
Assembly:  PresentationFramework (in PresentationFramework.dll)

public bool IsAtLineStartPosition { get; }

Property Value

Type: System.Boolean
true if the current position is at the beginning of a line; otherwise, false.

If the TextPointer points to an ambiguous position, for example, between two lines, the line in the direction specified by the LogicalDirection property is selected as the relative starting line.

The operation performed by this property depends on a valid layout. When necessary, this method attempts to automatically regenerate a valid layout before proceeding with the operation. Regenerating a layout can be a relatively expensive operation. Use the HasValidLayout property to check for a valid layout before performing operations that may regenerate the layout. For more information, see Layout System.
