Use Framework 4.5 and HTML 5....

Whats the problem? 

Found the problem, http://www.cryer.co.uk/brian/mswinswdev/ms_vbnet_server_error_potentially_dangerous.htm

Yeah, you need to fix that for AJAX request .

 

But we will improve the error message

Hi Terry,

 

I got the same problem as mentioned above. I already follewed the steps on the website given above but the problem still insist.

 

When I click on e.g. Add Image I get an alert pop-up with the source code of my page. After I close the pop-up and click on Upload image I got the same error message as above.

 

Any ideas I could try?

Have you try <httpRuntime requestValidationMode="2.0" in web.config?

Hi kjell.ek,

 

I've tried your suggestion but it didn't solved my problem. Thanks anyway.

And <%@ Page Language="VB" ValidateRequest="false"

That was my problem.....

It's a mvc 3 project so I can't do that.

 

After several try-and-error test we found out that the editor does a POST after we click the button. The method in the controller which invoke the editor also has a POST version (["HttpPost"]). Thats where it goes wrong.

I need to find a way to solve this problem.
