Adding Custom buttons to RadEditor's toolbar

RadEditor provides 4 different ways to add custom buttons to the its toolbar:

  1. Setting the tools in the RadEditor's declaration:
     <telerik:radeditor runat="server" ID="RadEditor1">
    <telerik:EditorTool Name="ApplySizeColor" Text="Apply Size and Color"/>
    telerik:EditorTool Name="InsertCustomDate" Text="Insert Custom Date"/>
    telerik:EditorTool Name="ResetContent" Text="Reset Content"/>
  2. Setting the custom buttons via the ToolsFile property:
    <telerik:radeditor ToolsFile="~/ToolsFile.xml" runat="server" ID="RadEditor2"></telerik:radeditor>
    <tools name="MainToolbar">
    <tool name="ApplySizeColor" Text="Apply Size and Color"/>
    tool name="InsertCustomDate" Text="Insert Custom Date"/>
    tool name="ResetContent" Text="Reset Content"/>
  3. Setting the custom tools programmatically via the codebehind:

    protected void Page_Load(object sender, EventArgs e)
    if (!IsPostBack)
            EditorToolGroup main
    = new EditorToolGroup();

    EditorTool applySizeColor = new EditorTool();
    applySizeColor.Name = "ApplySizeColor";
    applySizeColor.Text = "Apply Size and Color";

    EditorTool customDate = new EditorTool();
    customDate.Name = "InsertCustomDate";
    customDate.Text = "Insert Custom Date";

    EditorTool reset = new EditorTool();
    reset.Text = "Reset Content";
    reset.Name = "ResetContent";

  4. Setting the tools by using Theme:
    In your .skin file:
    <%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
    <telerik:radeditor runat="server" SkinId="SomeTools">
               <telerik:EditorTool Name="ApplySizeColor" Text="Apply Size and Color"/>
    telerik:EditorTool Name="InsertCustomDate" Text="Insert Custom Date"/>
               <telerik:EditorTool Name="ResetContent" Text="Reset Content"/>
    Once the skin is set, you need to declare it in the RadEditor's declaration by using the SkinId property:
    ="server" ID="RadEditor4">

    Note: More information on how to use ASP.NET 2.x Themes is available in MSDN

Declaring the custom CommandList that will be executed when the buttons are clicked:

After adding the custom toolbar buttons to the editor's toolbar, you should define their commands. In the page with the editor (after the <telerik:RadEditor ... declaration), add  the following script:

<script type="text/javascript">
"ApplySizeColor"] = function(commandName, editor, args)
"FontSize", {value : "4"}); //fire the FontSize command"ForeColor", {value : "red"});  //fire the ForeColor command

Telerik.Web.UI.Editor.CommandList["InsertCustomDate"] = function(commandName, editor, args)
'<span style="width:200px;border: 1px dashed #bb0000;background-color: #fafafa;color: blue;"> ' + new Date() + ' </span>');

Telerik.Web.UI.Editor.CommandList["ResetContent"] = function(commandName, editor, args)
""); //set empty content

If a custom tool is added without a CommandList command, then the clicked button will pop up a message that the command [commandname] is not implemented yet.

Set icons for the custom buttons

To improve the appearance of the custom buttons provide image files for them and declare or import with a <link> tag the following CSS classes in the page with the editor:

<style type="text/css">
.reTool .InsertCustomDate
: url(InsertDate.gif);
.reTool  .ApplySizeColor
: url(Custom.gif);
.reTool  .ResetContent
: url(Cancel.gif);

The syntax to follow is:

<style type="text/css">
.reTool .<commandName>
: url(MyImage.gif) !important;
