I'm adding a new button to the Sitecore rich text editor. I've used this link as a reference.

What I'm trying to do is have a button just like "Insert Sitecore Media" where when I click it I can add an image, but that image I want to add some inline styling to it(not something a content author will do but something I'll get done programmatically). If anyone have done something similar let me know.

So here's what I have done:

  • I have created the button on the core db with the click value as InsertFloatMedia
  • Within /sitecore/shell/contros/rich text editor/ I have created a folder InsertFloatMedia
  • Within that folder I copied and renamed the InsertFloatMedia.js and InsertFloatMedia.xml
  • I have tried to reproduce the same xml described on the example I mentioned just changing what needed for InsertFloatMedia
  • Have created a class and referenced it on the xml(this class is identical to the example)
  • have changed the Rich Text Commands.js and added this:

    RadEditorCommandList["InsertFloatMedia"] = function (commandName, editor, args) {
        var d = Telerik.Web.UI.Editor.CommandList._getLinkArgument(editor);
        Telerik.Web.UI.Editor.CommandList._getDialogArguments(d, "A", editor, "DocumentManager");
        //Retrieve the html selected in the editor
        var html = editor.getSelectionHtml();
        scEditor = editor;
        //Call your custom dialog box
            "/sitecore/shell/default.aspx?xmlcontrol=RichText.InsertFloatMedia&la=" + scLanguage,
            null, //argument
            500, //Height
            180, //Width
            scInsertFloatMediaCallback, //callback
            null, // callback args
            true, //modal
            Telerik.Web.UI.WindowBehaviors.Close, // behaviors
            false, //showStatusBar
            false //showTitleBar
    //The function called when the user close the dialog
    function scInsertFloatMediaCallback(sender, returnValue) {
        if (!returnValue) {
        //You may retreive some code from your returnValue
        //For the example I add Hello and my return value in the Rich Text
        scEditor.pasteHtml("Hello " + returnValue.text, "DocumentManager");


But when I try to execute this opening the RTE and clicking on the button a blank pupup shows up. inspecting the url of the iframe it looks like this:

enter image description here

Based on the image I see the page is empty(look at the body tag) If I inspect the src for out of the box ones when I click, they show properly. Anyone know what I'm doing wrong?

I was able to reproduce it and got a solution. You are probably missing one small thing.

  • Open new tab: http://domain/sitecore/shell/default.aspx?xmlcontrol=RichText.InsertFloatImage&la=en

  • Right now it will be empty.

  • Located the InsertFloatImage.xml file and open it

  • Make sure you have changed RichText.InsertImage node to RichText.InsertFloatImage, like this:

    <?xml version="1.0" encoding="utf-8" ?>
    <control xmlns:def="Definition" xmlns="http://schemas.sitecore.net/Visual-Studio-Intellisense">
            <FormDialog Header="Insert Float Media Item" Text="Navigate to or search for the image or media file that you want to insert." OKButton="Insert">
                <!--control code -->
  • Restart your application (this is super important! You have to do this to clean cache in Sitecore)
  • Go back to: http://domain/sitecore/shell/default.aspx?xmlcontrol=RichText.InsertFloatImage&la=en and refresh the page.


Now you should see your custom dialog. enter image description here I was able to display my custom dialog (changed title) and after I clicked Insert I was able to hit the js breakpoint .
