Problem on display many XML files in web broswer IE

[=?Utf-8?B?ZGF2aWQ=?=]

I use datagrid to store XML file information for selecting a XML from
database, and a textbox, txtXML, for displaying a selected XML.

When I dispaly a XML in the textbox at firstime, it OK. But when I select
another one to display, I got an error message and a security warning in the
following attached.
I think that the browser sends bacl the first dispalyed XML back to Server,
when I want the second one.

Anyone could tell me how to get rid of it. Thanks

David

A potentially dangerous Request.Form value was detected from the client

Description: Request Validation has detected a potentially dangerous client
input value, and processing of the request has been aborted. This value may
indicate an attempt to compromise the security of your application, such as a

validateRequest=false in the Page directive or in the configuration section.
However, it is strongly recommended that your application explicitly check
all inputs in this case.

Set enableRequestValidation="false" in your page's @Page directive.

You got it. I was thinking of the attribute for the pages element in the
web.config. Same thing.
