TextSpan.Underline Property

Gets whether the text span’s characters are underlined.

Namespace: DevExpress.Blazor.RichEdit

Assembly: DevExpress.Blazor.RichEdit.v24.2.dll

NuGet Package: DevExpress.Blazor.RichEdit

#Declaration

C#
public bool? Underline { get; }

#Property Value

Type Description
Nullable<Boolean>

true if characters are underlined; false if characters are not underlined; null for a combination of true and false.

#Remarks

The UnderlineColor property defines the underline color of a text span’s characters. If this property is set to Empty, the underline color depends on the ForegroundColor property value.

The UnderlineWordsOnly property allows you to get whether space and tab characters are underlined in addition to other characters.

Use the ChangePropertiesAsync(Action<CharacterProperties>, CancellationToken) method to change whether a text span’s characters are underlined.
