Image tag border attribute is deleted by editor

[Laurie]

When inserting an image via the Image Manager, the css for the height, width, border attributes that are chosen is properly generated.  However, for better compatibility with some email rendering clients, I also need to have these attributes exist as html image tag attributes (for example:  <img width="100" height="100" border="2" .)  When I manually add these attributes to the image tag, I find that the editor deletes the border attribute.  How can I prevent this deletion from occurring?  I have uploaded examples to show what I manually add and what the editor keeps/deletes.  Thank you.

Hi Laurie,

You can disable the ConvertToXhtml filter because the border attribute is not valid XHTML:

RadEditor1.DisableFilter(EditorFilters.ConvertToXhtml);

Creating valid XHTML content is of vital importance for RadEditor and as such it is its first priority.

Thank you so much.  Your reply is very helpful!  I had forgotten about image border attribute and XHTML.  As we will prefer to leave the filter in place, I can work around by placing images into tables, then style the tables.
