A potentially dangerous Request.Path value was detected from the client (&)

Hi,

We have a problem and strongly suspicious about telerik components about this request.

Our firewall and .net seem the below url as dangerous because of first & sign. We checked our scripts and codes which has a potential to generate such a url, but we couldn't find.

http://xxx/$$$&?&?$$$?cmd=get_file&arg=block_style.css&sid=2721D35AB490C1FAA14DC203E330729AE1AD88B7

Can you please check that your components may generate such a request url ?

We are getting first exception and then the second one, even we cannot find any strong relationship between them, they seems sequentially...

Problem with Insert Symbol on IE

When you add a symbol to the end of a line in IE, the cursor moves down to the next line. This behavior does not exist in FF or Chrome, and it did not exist for IE in previous versions of the Editor.

Here is a video demonstrating the problem using the Telerik demo editor.

http://screencast.com/t/9S0TjfZzyFqj

Please advise on a solution to this problem.

Thanks,
Trevor.

unable to deselect table on iOS

The problem can be seen on the demo editor.

On iOS, tap the "Insert Table" toolbar button to add a table to the editor content window,
Notice that the new table is 'selected',
If you tap somewhere else in the content window, the table remains selected

In a desktop browser, the table will become deselected as soon as you click elsewhere in the content window. On Android, the table becomes deselected as soon as you tap elsewhere in the content window.

Can I get a solution to this problem?

Thanks,
Trevor.

Required Field Validator

Hi, when one of the controls of the FormTemplate has RequiredFieldValidator, clicking edit or Add new record not working. I am getting error:
"NetworkError:
500 Internal Server Error -
http:.../ScriptResource.axd?d=nv7asgRUU0tRmHNR2D6t1B_9fiS5OJY3KTRMAF4D17Hlkgb15LTvxIFD9V60xX_vkRJU81TFs8HNZhyOtmOQ3BeUAV6sJwN0m6XD0jm6Dg-1FSTXmC_cPUhXqUD-lmHVpRtmvKgLT4XLk7tOAE-VhQ2&t=362a7238"
When setting property EnableClientScript="False" it works.

I cannot use Client validation with RadGrid?

Regards,
Lev Rakhman
