XML Escaping for Textbox

[Nick]

Hey there,

I'm trying to get a textbox (using ASP.NET / VB.NET) to display XML
without freaking out the browser afterwards.

Currently I have the textbox displaying the XML fine, but that's when
things go funny, the second another postback occurs it complains. I thought
that a textbox would have it's contents escaped in on way or another,
obviously not, any idea how I can get the page to ignore it's contents? I
don't want it to use the contents for anything, it's just for the users
convenience.

Error: Sys.WebForms.PageRequestManagerParserErrorException: The message
recieved from the server could not be parsed. Common cause for this error
are when the response is modified by calls to Response.Write(), response
filters, HttpModiles, or server trace is enabled.

Cheers in advance for your time!

Nick.

Turn off ViewState on the TextBox so that the data in the Textbox is not
held onto during the between round trips. That means you'll have to populate
the controls each time on the postback with the XML.

Hi Nick,

Based on your description, my understanding is that you use a TextBox on
page to accept some input and you assign some XML text into the textbox ,
however, when you post back the page, it report some error, correct?

In the error message , I saw the "Sys.WebForms..." component which is
ASP.NET ajax script class. So are you using AJAX in that page to perform
partial postback(non refresh post)? If so, would you provide some further
code logic about how to did the AJAX stuff or an simple example of the page
so that we can also perform test on my side? BTW, have you tried Arnold's
suggestion to see whether it helps?

Hi Steven,

I've found an alternative way to display the information I want without
using a Text box but using an iFrame instead which solves the issue I have
been experiencing.

Thanks a million for your time and help none the less.

Nick.

Hey there,

For some reason this post only just appeared! I blame Outlook Express.

Anyway thanks a million for the tip, I thought there must be some way of
excluding it, that's great, cheers.

Nick.
