Programmatically Refreshing the PageOne 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. Hi
Do not know if i am correct did u try meta refresh tag of HTML. Shivprasad Koirala C# , VB.NET , SQL SERVER , ASP.NET Interview Questions http://www.geocities.com/dotnetinterviews/ 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. -- Show quoteHide quoteNathan Sokalski njsokal***@hotmail.com http://www.nathansokalski.com/ <shiv_koir***@yahoo.com> wrote in message news:1123904916.645353.180630@o13g2000cwo.googlegroups.com... > Hi > > Do not know if i am correct did u try meta refresh tag of HTML. > > > > Shivprasad Koirala > C# , VB.NET , SQL SERVER , ASP.NET Interview Questions > http://www.geocities.com/dotnetinterviews/ > "Nathan Sokalski" <njsokal***@hotmail.com> wrote in I think you have a misunderstanding of how the web works...

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. -- Lucas Tam (REMOVEn***@rogers.com) Please delete "REMOVE" from the e-mail address when replying. http://members.ebay.com/aboutme/coolspot18/ 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. Shivprasad Koirala C# , VB.NET , SQL SERVER , ASP.NET Interview Questions http://www.geocities.com/dotnetinterviews/ Hi, Nathan.
You might want to take a look at: "Generating Client-Side Script for Postback" http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpcongeneratingclient-sidejavascriptforpostback.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/default.asp?url=/library/en-us/cpguide/html/cpconpostbackusingjavascriptsample.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/default.asp?url=/library/en-us/cpguide/html/cpconrenderingservercontrolssamples.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/loadpost/simplewait.aspx http://www.daveandal.net/books/6744/loadpost/progressbar.aspx There's links to source code in both.

I assume that the other sample I did sent in your other questions give you an answer on this? I hope this helps, Cor 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.HttpContext = GetHTTPContext() httpCxt.Response.Redirect(httpCxt.Request.RawUrl) ' RawUrl contains the full url, including parameters. End Sub Public Shared Function GetHTTPContext() As System.Web.HttpContext Return (System.Web.HttpContext.Current) End Function Show quoteHide quote "Nathan Sokalski" <njsokal***@hotmail.com> wrote in message news:eH0ql66nFHA.3408@tk2msftngp13.phx.gbl... > 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).
