Modifying existing radeditor dialogs

[Graham Berry]

Hi,

I have read the article on "Disabling the Anchor tab on the Link Manager" and that seems straight forward but I want to add a new property, tracktag,  to the Hyperlink Manager tab - is this possible?

I have looked in the LinkManager.ascx and this seems fine and I can create a new field and label for my tracktag property but how do:

1. Save the tracktag property in to an attribute in the created anchor link
2. retrieve the value of the tracktag if its an existing anchor link

It really would be a pain if I had to create new customised dialogs for this purpose.

Also, is there any detailed information regarding radeditor extensions and they seem to be in snipets all over the place.

Thanks,
Graham

Hi Graham,

In order to achieve the required functionality you need to modify the several methods of the LinkManager prototype.

1. The setupChildren() function initializes the input fields and comboxes inside the dialog. In this function you need to register the new property of the LinkManager object and assign it to the input field representing the custom attribute field, e.g.:
   HTML Markup
   

   <tr>
       <td class="reLabelCell">
           <label for="LinkTooltip" class="reDialogLabel">
               <span>CustomAttribute </span>
           </label>
       </td>
       <td class="reControlCell">
           <input type="text" id="CustomAttribute" />
       </td>
   </tr>

   setupChildren function's body
   

   this.customAttribute = $get("CustomAttribute");

2. To store the value entered in the custom input field you need to modify getModifiedLink() function. This is the method which creates or modify the link DOM element, e.g.:
   

   if (this.customAttribute.value.trim() == "")
   {
       resultLink.removeAttribute("CustomAttribute");
   }
   else
   {
       resultLink.setAttribute("CustomAttribute", this.customAttribute.value.trim());
   }

   
   
3. To populate the input field with the correct value (empty if it is a new link, or set the value of the CustomAttribute attribute of the selected link element) you need to modify the _cleanInputBoxes() and _loadLinkProperties().

For your convenience I have attached modified LinkManager.ascx file. The modifications that was made are wrapped with comments, e.g.:

//customAttribute
........
//customAttribute --- END

I hope this helps.
