This property, in conjunction with the SelLength and SelStart properties, is useful for tasks such as setting the insertion point, establishing an insertion range, selecting substrings, or clearing text in the cell being edited.
Setting this property to a new value sets the SelLength property to 0 and replaces the selected text with the specified text.
This property can only be set or retrieved when the control is in edit mode, which can be determined by using the IsInEditMode property. If the control is in edit mode, the ActiveCell property can be used to determine which cell is currently being edited. If the control is not in edit mode, attempting to use this property will generate an error.
Note: Accessing this property will throw an exception if the cell is not in edit mode or the underlying editor being used does not support selectable text, that is its Infragistics.Win.EmbeddableEditorBase.SupportsSelectableText must return true.
