One thing that I have often needed to do that I have been unable to find a
way to do is refresh the page (basically do the same thing as pressing the
browser's Refresh button). I know how to do this using Javascript/JScript,
but I have situations in which I need it to be done immediately after code
that is part of my other code. Is there any way to do this? Thanks.

You seem to have misunderstood my question. I want the refreshing to occur
when, and only when, it is called in my code. For example, I might have a
graphic that gets changed when the user presses a button. They do not see
the new graphic unless the page is refreshed. I want to be able to
automatically refresh the page after the graphic is modified, but I don't
want the page to be continually refreshed, because that would be inefficient
and mean that the user might need to wait a certain period of time
(depending on how frequently I set the meta tag to refresh) before seeing
the new graphic.

I think you have a misunderstandin g of how the web works... The web works
in a request-response fashion, only clients can make requests for data.
Hence, the server (ASP.NET) can force a refresh.
There are a couple solution to emulate what you want:
1. Refresh continously
2. Poll the server via javascript remoting, when the server returns a
positive response, refresh thte apge
Option 1 is easy. Option 2 takes some knowledge of javascript.

Nathan,
I assume that the other sample I did sent in your other questions give you
an answer on this?
I hope this helps,

Ok got it then you can use Cache object where you can specify when the
object changes referesh the cache.
Cache object can further be customized on lot of parameter like values
, time , change in file etc etc.

Hi, Nathan.
You might want to take a look at:
"Generating Client-Side Script for Postback" http://msdn.microsoft.com/library/de...orpostback.asp
That article explains how to generate a postback event
in controls other than buttons and image buttons.
Make sure you follow through to the accompanying article: http://msdn.microsoft.com/library/de...riptsample.asp
That sample creates a custom link button
that initiates postback through client-side script.
For a sample which derives from WebControl,
see "Rendering a Server Control Samples" : http://msdn.microsoft.com/library/de...olssamples.asp
I see what might be a problem in using these methods, and it's that
synchronizing the client-side script so that it executes *after* your
new image has been created might be tricky.
You might want to consider adding a "Please wait..." message
or a progress bar to your code and introducing a time delay
for the postback to occur, so that enough time elapses before
the page is refreshed by the postback.
For "Please wait..." and progress bar example code, see : http://www.daveandal.net/books/6744/...implewait.aspx http://www.daveandal.net/books/6744/...ogressbar.aspx
There's links to source code in both.

I'm not sure if this will help but; this is what I do when I want the page
to be refreshed. It is server based, I find it nessary if a resource on the
server has changed and I want it reflected in the browser.
Public Shared Sub RefreshPage()
Dim httpCxt As System.Web.Http Context = GetHTTPContext( )
httpCxt.Respons e.Redirect(http Cxt.Request.Raw Url) ' RawUrl contains
the full url, including parameters.
End Sub
Public Shared Function GetHTTPContext( ) As System.Web.Http Context
Return (System.Web.Htt pContext.Curren t)
End Function

Nathan -
You can write a little routine to force the page to refresh. You ca
then call this procedure whenever you need to:
In the code behind you will need:
'Build dynamic script to force a postback to the page to get th
new info
Private Sub ForcePostBack()
Dim strRedirectBuil der As StringBuilder = New StringBuilder
strRedirectBuil der.Append("<sc ript language='vbscr ipt'>")
strRedirectBuil der.Append("For ceRefresh()")
strRedirectBuil der.Append("</script>")
Page.RegisterSt artupScript("Re direct"
strRedirectBuil der.ToString)
End Sub
Then in your script you would need:
public sub ForceRefresh()
dim strPath
strPath = "<pagename>.asp x"
window.navigate (strPath)
end sub
Hope this helps

How can this be done? The information will come from a database and the

Hi,
i'm not sure to understand the difference between refreshing the pagina by
clicking on 'refresh' in the browser and a postback.
What i think it is:
Suppose a page with a form containing a textbox and a dropdowlist: and a
button to start something n code-behind:
a refresh doesn't send any value back to the server but with a postback, the
values are sent?
But then, which role does Viewstate play in the postback proces?
