ListLevel.DisplayFormatString Property

Gets the pattern used to format the list level’s number or bullet.

Namespace: DevExpress.Blazor.RichEdit

Assembly: DevExpress.Blazor.RichEdit.v24.1.dll

NuGet Package: DevExpress.Blazor.RichEdit

Declaration

public string DisplayFormatString { get; }

Property Value

Type	Description
String	The format pattern.

Remarks

The format pattern can include fixed literals and indexed placeholders.

An indexed placeholder is an integer from 0 to 8 enclosed in curly brackets (for instance, “{0}”). A placeholder index corresponds to the list level’s number or bullet depending on the ListLevelFormat property value.

Use the list’s ChangeLevelPropertiesAsync(Int32, Action<ListLevelProperties>, CancellationToken) method to change the format pattern of a list level. The following example shows how you can set the ◆ bullet for the 0 list level.
