Using a panel question

[Brad]

I have a form where I have a treeview control in the left sidebar and then a
panel next to it in the other pane. Based on user selection from the tree
view, I would like the panel to display a certain html page that was created
in Word as html. Currently I do have the treeview's nodes pointing to a URL,
however for design asthetics, I would love to have the html page just open in
this panel.

How would I got about doing this and thanks for the help.

ASP:PANEL is a <DIV> tag when rendered to HTML and <DIV> cannot host another
HTML page. Adding an IFRAME to the right panel may be an option. IFRAME can
host new HTML/ASP/ASPX pages.

Brad,

I wouldn't go the iFrame route myself. You can certainly display the page in
the panel.

Put a literal control into the panel and then get the html code like this:

'---Create the request

Dim WebRequest As System.Net.WebR equest

WebRequest = System.Net.WebR equest.Create(N ew Uri(CurrentLink ))

'---Optionally set the timeout (if you don't the default timeout will be
used)

WebRequest.Time out = 2000

'---Get the response produced by the request

Dim Response As System.Net.WebR esponse = WebRequest.GetR esponse

'---Download the page content into a stream

Dim Stream As System.IO.Strea m = Response.GetRes ponseStream

'---Place the stream into a stream reader

Dim StreamReader As New System.IO.Strea mReader(Stream)

'---Read the stream into a string object

Dim Html As String = StreamReader.Re adToEnd

'---Cleanup for the next request

Stream.Close()

StreamReader.Cl ose()

Literal1.Text = Html
Now, you may need to parse the html to remove html, head, and/or form tags
depending on what the html you are receiving contains. There are, of course,
tags that could mess up your page's display. But I use this technique to
display newsletters saved as html pages in an archive site and the
surrounding site's format is just fine in every browser. You'll just have to
test to see if any included tags mess things up and remove them from the
Html string if they do...

There is a lot of overhead in the technique you just described.
For performance reasons I think I'd have to lean toward the IFrame approach
for most situations, depending on your requirements.

Yes,

I'd agree, if an iFrame is compatible for all potential users of the
application, then that would be the way to go. It's just that while iFrames
are being adopted by more browsers there are still a lot of users out there
who are using older browser versions or browsers that don't render
iFrames...
