Stuart,

 

Here are my suggestions:

 

When the page loads, we need to populate the editor.

 

string temp = "";'

temp += "type here";
temp += "<div contentEditable="false" UNSELECTABLE="ON">This Heading is not editable.</div>"; // You can put the data from recordset here.
temp += "type here again";


Editor1.Text = temp;

Hope it helps.
