I have been building a Content Management System which will be used for several of my clients, and I have been hoping to use RadEditor However, I have run into a really tough issue. For some of these clients, the majority of content this CMS system will be managing will be email content. RadEditor generates XHTML-compliant code which is great... if you're displaying content in a browser. However, Email clients don't always like XHTML code at this point and the content is often broken. For instance, images that have style declarations which specify their width/height will not be displayed properly in Outlook and other email clients. Images need to have their width/height attributes set in order to function correctly in email clients. I found a thread which discusses this exact problem at:
The solution provided (that of creating a custom filter) appears to have some issues. First off, when you insert an image from ImageManager, the custom filter works to rewrite the tag using attributes instead of style, however, the width/height it specifies is the width/height of the physical image, not the width/height specified in the Properties tab of the Image Manager. So, I can insert an image that has w/h of 300x200 and its attriubtes will be set correctly using the filter, but if I wanted to set the w/h to 600x400 in the Image Properties Dialog and/or tab in the Image Manager, the filter won't do this.
Apparently, the Image Properties dialog and Image Manager Properties Tab operate only on the style attribute of the img tag. This makes sense, sine you're tying to create and manipulate XHTML-compiant code, but of course, isn't particularly helpful in this scenario.
The solution above is also a bit problematic because I believe this style vs attributes issue applies to other types of elements, besides the img tag. Even if it were possible to overcome the properties issue I noted above, it would likely be very difficult to create an exhasutive filter that handles any and all tags and their attributes that are affected by this.
Anyhow, I'm hoping someone out there has created some sort of system that allows them to create content using Rad Editor that will work in email clients. Or, I'm hoping Telerik can provide a more workable and robust solution than the one in the link above. If not, I'm afraid I will have to forego using RadEdtior in my CMS system, which would be sad since I think the control is excellent otherwise.
