    Problem with TextArea and TexField - accepting XML text

    Hello All,

    I read i think all threads about this :) But still didnt understand how to resolve my problem without changing ValidateRequest for page.
    I just need to have TextArea where user can write XML / HTML code, and then send this text to the server, or init this area with
    code from server.
    I think that this is very simple situation, but i still didnt find a way how to do this.

    Hi,

    You can encode/decode a html string.

    Hello Daniil,

    Thank you for you reply.
    Problem is that encode is ok when i want to set value of TextArea with XML from server,
    but when i want to submit data - i cannot do html encode on the fly, before request is sent to server,
    or at least i don't know how to do this from code behind.
    I did same with HTMLEncode/decode without problems for grid panels for example, adding params
    to rowclick direct evetns.
    But didnt did this with Textarea, simply because here button can be not on the same panel where
    is textarea, but in tab panel, where this panel is, or even in higher level.

    Regards,
    Nedelcho

    You can set up SubmitValue="false" for a TextArea and submit it manually, for example, as an extra parameter of a DirectEvent.

    }
</script>
