TinyMCE preview and custom drop down menu

Please get the latest code before starting We have a tinyMCE editor to edit help pages and emails. TinyMCE is a wysiwyg editor. We need to provide a preview of the page they are working on, and also add some custom tag items to insert into to the text. The code is located under [login to view URL] We will focus on Edit function. (Create is similar) Task A(1H): Include a button called Preview that will show the page as html rendered content. The preview should open in a separate window. Each time the user clicks on the preview, this preview window should be updated instead of opening a new window each time. The preview must show the content without saving first. Task B(2H): Include a custom menu button with a multi dropdown array. Look at this link for example to create multi level button [login to view URL] There are 2 levels. In PController there is a function called GetDemoData that will return Dictionary>. Dictionary will contain the group name (Transaction, User, Customer, User-Plan-Ref), and for each category there is a List containing the entries for next level, and the demodata to view So a structure might be |-Transaction | |-Transaction Id | |-Payment date | |-Amount |-Customer | |-Name plus more In the MailTokenHolder, the Description is what should be displayed in the Menu (Like Payment date), and the [login to view URL] is what should be inserted into the text at the current location (eg. {{[login to view URL]}}). Task C(3H): We have some codes within the text identified by {{ and }}. These must be replaced with demo content when previewing. So the Preview function should replace all {{token}} with valid demo data. Now the MailTokenHolder contains demo data. Have a look at [login to view URL] - public static void decodeMail(ref String subject, ref String body, Dictionary args) You can use this function by merging all demodata into a dictionary containing (Token, DemoData). The last argument Dictionary args is a list of all tokens and their data. Create a Dictionary args = new Dictionary(); So traverse the [login to view URL](). Then for each category, traverse all MailTokensHolders and add to args like [login to view URL]([login to view URL], [login to view URL]) Then call [login to view URL](ref subject, ref body, args) and show the result
