How to switch content page?

[Ben]

Hi,

i'm trying to build a simple site navigation (using c#)... i
implemented a master page that shows a sidebar user control on the
left side, and a content page on the right.

i click the link on the sidebar which calls Redirect.

problem is that the whole page refreshes... i just want the right side
to update to a new content.

can anyone point me in the right direction to accomplish this?

btw, i'm trying to use ajax when possible to make the job easier...
but if i put the sidebar in an UpdatePanel (in hopes of avoiding a
refresh) it gives this error:

"Sys.WebForms.P ageRequestManag erParserErrorEx ception: The message
received from the server could not be parsed. Common causes for this
error are when the response is modified by calls to Response.Write( )"


Thanks for any info you can give!

Thanks Mark -- That's why I looked into master pages, since i read
that framesets are a thing of the past...

content) and leave the left (the menu sidebar) intact?

Not with MasterPages...

It doesn't look professional when the whole page refreshes every time
someone clicks a new menu item....

That's the way the web works...

or is the only way to accomplish this using framesets?!?

One of the main features of MasterPages is the server-side interoperabilit y
between the content pages and MasterPages - you can't really do this with
framesets or iframes, so you're left with client-side JavaScript.

Obviously, you could create an asp:Literal control and fill it dynamically
with HTML, but that would mean that you would lose all of the server-side
ASP.NET functionality.

I would strongly advise you to stick with MasterPages - once you've got the
hang of them, you'll wonder how you ever managed without them...

yea, i want to avoid dynamically filling the HTML on the client
side... i was really hoping for the exact same functionality framesets
provided (being able to reload a particular frame), i just thought
there's an alternative that would behave in a similar way.

u know that MSDN page for the subscriber downloads... it's got a
navigation tree on the left, and it doesn't refresh when you click
things, just the content pane refreshes... that's what i wanted...
maybe they're using framesets...

btw, if there's any recommended book u can suggest that covers these
topics (i'm using VS 2008 now), let me know, i'd really appreciate
it... i think i need to get some basics down.

thanks!!

The "content" pages are static HTML stored in a database...

It might be easier for you to consider building your side menus into your
content pages instead of the master page. Then you could definitely do
partial page updates using nested update panels.

Apart from the fact that that would totally defeat the purpose of
MasterPages...

This is closer to what i need though... i'd rather not use a master
page in this section if it forces a full refresh.

I''m testing it now... so built a table with 2 columns in a webform,
one side has my menu and the other an UpdatePanel.
On menu item click I load a new Web User Control into the UpdatePanel
using this code:

UpdatePanel.Con tentTemplateCon tainer.Controls .Clear();
UserControl uc =
(UserControl)Lo adControl(sPath ToWebUI);
UpdatePanel.Con tentTemplateCon tainer.Controls .Add(uc);

It has a strange behavior -- when the contol loads, I click on a
button and it doesn't post back... i click again and only then it
works... is there anyway to fix this?

Re: How to switch content page?

I tried recreating your columns and update panel just to test it. I added a
"parent" update panel that holds everything except the Script Manager. And
then I dropped a variation of your code into my button onClick, which
created a Textbox control in the right column's Update Panel.

As expected, the partial post back worked fine. (with the "parent" Update
Panel). I would suggest, breaking through your user control; the two-click
bug might be in there.



I'm not sure what the code for your control looks like.
