    Using Google Translator tool I add a custom dropdown on the RadEditor toolbar with a JavaScript function. The translator dropdown works either on selected HTML or if no selection translates the whole content in the editor.

    Here is how to add the custom dropdown to RadEditor toolbar:
    1) Register the Google's JS API by adding the following script tag inside the <head> tag of the page with the editor:

    <script type="text/javascript" src=""></script>

    2) Create the custom translation dropdown by adding the telerik:EditorDropDown  tag to Tools inner-tag of the RadEditor declaration:
    <telerik:RadEditor ID="RadEditor1" Skin="Telerik" OnClientCommandExecuting="OnClientCommandExecuting" runat="server"
                <telerik:EditorDropDown Name="TranslateTool" Text="<img src='./flags/en.png' /> Translation Tool" width="130" ItemsPerRow="1" PopupWidth="110" PopupHeight="300"
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/en.png' /> English (UK)" value="en" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/es.png' /> Spanish" value="es" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/de.png' /> German" value="de" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/fr.png' /> French" value="fr" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/it.png' /> Italian" value="it" />                     
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/ru.png' /> Russian" value="ru" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/pt-pt.png' /> Portuguese" value="pt" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/he.png' /> Greek" value="gr" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/nl.png' /> Dutch" value="nl" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/ja.png' /> Japanese" value="ja" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/bg.png' />  Bulgarian" value="bg" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/ro.png' /> Romanian" value="ro" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/uk.png' /> Ukrainian" value="uk" /> 
                     <telerik:EditorDropDownItem  Name ="<img src='./flags/sv.png' /> Swedish" value="sv" /> 
            This is sample content for translation!     

    To populate the items of the dropdown use the telerik:EditorDropDownItem inner-tag of telerik:EditorDropDown. The Name attribute of the telerik:EditorDropDownItem tag represents the item name that will be rendered in the dropdown and the Value represents the value of the selected item.

    You can add as much new languages supported by Google Translator in the dropdown as you wish.

    To visualize the icons inside the dropdown items copy the flags folder to the root of your web application. The flags folder is available in the attached sample project.

    3) After adding the custom dropdown to the editor's toolbar, you should attach a function to the editor's OnClientCommandExecuting, the arguments of which will give you reference to the selected dropdown name and value.  Once you obtain the selected item's value, you can modify it and paste it through the pasteHtml function in the content area, e.g.

    <script type="text/javascript"
    function OnClientCommandExecuting(editor, args) 
        if (args.get_name() == "TranslateTool"
            //Get language 
            var language = args.get_value(); 
            //Use either selected HTML or if no selection use all HTML                 
            var hasSelection = true
            var html = editor.getSelectionHtml().trim(); 
            if (!html) 
                html = editor.get_html(true); 
                hasSelection = false
            google.language.translate(html, "", language, function(result)  
                if (!result.error)  
                   currentSelectedHtml = result.translation; 
                   //Either paste at current location or replace whole editor content 
                   if (hasSelection) 
                   else editor.set_html(currentSelectedHtml); 

    For your convenience, I have attached a sample working project.

    Hi Atul,

    The provided approach to implement a translate tool is 5 years old. Surely Google has changed the way their API is used.

    Note that this code library is provided only as a demonstration and if further issues occurs due to new API features, they should be handled per case.

    I suggest investigating if you are able to invoke the google translation functionality without the editor. If you have specific difficulties on using the RadEditor control, please provide more details about them. 

    On a side note, the used version of the Telerik UI for ASP.NET AJAX suite is quite old, and surely not supported under modern browsers. Due to that I recommend you upgrading it. 

    Do you want to have your say when we set our development plans? Do you want to know when a feature you care about is added or when a bug fixed? Explore the Telerik Feedback Portal and vote to affect the priority of the items
