Property Value

Type	Description
Nullable<Boolean>	true if no space or tab character is underlined; false if all space and tab characters are underlined; null if only some space and tab characters are underlined.

Remarks

A cell stores its text formatting settings in the CharacterProperties property. The Underline property returns whether characters are underlined. The following properties affect underline appearance:

UnderlineWordsOnly

Returns whether space and tab characters are underlined in addition to other characters.

UnderlineColor

Returns the underline color. If this property is set to Empty, the underline color of the characters depends on the ForegroundColor property value.

Call the cell’s ChangePropertiesAsync method to change the underline color of table cell characters. The following example underlines all characters in the first row:
