Namespace: DevExpress.Web.ASPxHtmlEditor

Assembly: DevExpress.Web.ASPxHtmlEditor.v24.1.dll

NuGet Package: DevExpress.Web

Declaration

C#

public override string CommandName { get; set; }

VB.NET

Public Overrides Property CommandName As String

Property Value

Type	Description
String	A String value that represents the button’s command name.

Remarks

A command’s name can be used on the client side when calling the client ASPxClientHtmlEditor.ExecuteCommand method or handling the ASPxClientHtmlEditor.CommandExecuted client event.

Example

ASPxHtmlEditor allows you to provide custom toolbar buttons and modify the functionality of default buttons.

In this example, two custom buttons and corresponding shortcuts are created: Clear and Add Signature. When a button is clicked or shortcut is pressed, the ASPxClientHtmlEditor.CustomCommand event is triggered. In the event handler, the default select all and delete commands are executed using the ASPxClientHtmlEditor.ExecuteCommand method.

Additionally, we have modified the functionality of the default insert ordered list command. In the ASPxClientHtmlEditor.CommandExecuted event handler, which is triggered after the command is processed, we change the type of ordered list markers to Roman numerals.
