RadEditor: why old "HTML" takes the input from "Preview", not the new "Content"?

[Stanley]

This is the old sample, it works for me: 
http://demos.telerik.com/aspnet-classic/controls/examples/integration/aspnetajax/autosaveradeditor/defaultCS.aspx
    
Here are my steps

1. In "Design View", I insert a "Textbox".
2. Swith to "Preview", click the newly add Textarea, typein "abc".
3. Swith to "Html" view, I can see my input was taken - it was changed to <INPUT style="WIDTH: 100px; HEIGHT: 22px" value=abc>

I tried same steps for the new sample, but I can not see "value=abc" added:

Please point to me what I missed (or it is a bug?), thanks for your help!

Hi Stanley,

This is a browser related behavior which appeared in IE9. RadEditor Classic does not support the modern browsers and its demos run in IE7 standards document mode and for this reason the behavior does not exist.

To fix the problem put one of the following meta tags in the head of the page with RadEditor for ASP.NET AJAX:

<meta http-equiv=X-UA-Compatible content=IE=7>

or

<meta http-equiv="X-UA-Compatible" content="IE=8" />

Best regards,
Rumen

Thanks!
