This property informs on whether a certain attribute has the same value as the value of the complete selection.

Possible attributes are:
- Baseline: Specifies the attribute set through the Baseline property.
- Bold: Specifies the attribute set through the Bold property.
- FontName: Specifies the attribute set through the FontName property.
- FontSize: Specifies the attribute set through the FontSize property.
- ForeColor: Specifies the attribute set through the ForeColor property.
- FormattingStyle: Specifies the attribute set through the FormattingStyle property.
- Italic: Specifies the attribute set through the Italic property.
- Strikeout: Specifies the attribute set through the Strikeout property.
- TextBackColor: Specifies the attribute set through the TextBackColor property.
- Underline: Specifies the attribute set through the Underline property.
The following VB.NET code return true, if the complete selection is formatted in bold.
