I tried just like you say, but the problem is not about the only saving a file.

İf (I load nothing to editor || The editor is empty)

 

                                  there is no problem the method Editor1.SaveFile(filename);

                                  it works very well;

if (I load a content of file to editor || Something was initialized to editor)

 

                                  I cannot manage to save the file with changes;

                                  The saving process happends but Editor1.XHTML doesn't include the changes;

                                  Editor1.XHTML is the same with initialized form or was loaded from;

Please Help...
