The user clicks on a button on a page and as a result he gets a new page send back.
Most times everything is fine now, but sometimes this page needs to be updated within a few seconds but the user don't knows this.
I know I can poll from the client site with reload, but this does not fit here.
I need a kind of push update from server to client ... the action must be initiated from server, not from client ...

I've been stuck on this one for a while, so it's time to consult the pros. I've created a charting application that uses javascript to do heavy DOM manipulation/generation on the client (creating barcharts made of colored divs, etc).
Long story short, I want to avoid sending my js library to the client. Is there any way to create the content on the server, using my existing javascript library, and only send the javascript-generated HTML to the client?
I'm looking for possible ways for sending files from browser to server.
One obvious way is using form with enctype='multipart/form-data'.
I wonder if there are other ways than this.
The reason I ask you this question is this file uploader: http://aspnetajax.componentart.com/control-specific/upload/features/core_features/WebForm1.aspx
It's not flash based, but it sends the file in a way that it gives you a progress bar, but when you send a file with form with enctype='multipart/form-data' the whole file will be send to the server so you can't actually show a progress bar of uploading process.
I am developing the web site, It consists of device name list and related Build Button. When one click the Build button the one process will run in server.

View 2 Repliesthe idea id I need to send data to the client to the server to inform the server of some events at the client, and i need to send data from server to the client to inform the client of some results on the server. now from client to server is easy I use xhr easy enough. and to send data from server to client I thought of using long polling in xhr so to test I wrote the following code:
[code]
<!-- Test.aspx -->
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" %>
as per my flow on every click i have a postback without which i cannot store data to client or server.i have 2 ways of data storing one is client side in javascript variables in form of array(which can be lost on postback) the data to be stored are of differnt types some are numeric , some single characters some sepearted with comma other way is on each post back save the data in a session varibale on server & then access currently i have second way considering both the ways and in accrodance with the current flow which is best for maintenance & access speed reasking as i am notyet cleared abt the things.

We have an ASP.NET web application and it's hosted using IIS 6.0, in the app we have these several javascript and css files located in a folder, and for performance sake (according to YSlow) we set the folder content expiration header to 1 year. Everything worked just fine until recently when we deployed the latest build to the server, in which we had made some changes to those javascript and css files. For some reason after the deployment some of our end users don't see the latest changes when they connected to the app, even after they cleared the cache in IE. We have also restarted the IIS on the server and the problem still remained. When I went into the IE Temporary Internet Files folder on one of these machines I saw the files were still the older version and not the latest one, I had to manually delete the files from the Temporary Internet Files folder then they were able to see the latest changes. I'm baffled by this, how come only some users who couldn't see the changes but some others do (without having to do anything by the way), and how do I make sure that for future releases we won't have to do anything like what did (manually deleting the cached files)? For now I disabled the Content Expiration option in IIS for these files but I would like to know if there is a way that I can enable the content expiration (to help performance) but at the same time making sure when the files are updated, the latest version will be used for the end user (instead of the cached version)?

View 1 RepliesI am new to asp.net, so this might be a basic question. But I am struggling on this for more time... I have loaded a COM object in Server script using code behind (C#) and that COM object will trigger events in some random interval. I need to update the client page whenever I receive an event from the COM object from server side (code behind).My question is, Is there a way to make the client page do postback from the code behind(C#)? ie., The client page needs to be updated whenever an event occurs in the server. Is that possible? The com event does not trigger a postback since it only occurs in the server and not in the client.

I have a requirement where a user logs on to a server where exists a website. The user bring up the site on a browser on that server and loads a power point presentation slide. At that time, users using their laptop clicks on the link to that site and sees that particular PPT slide loaded on the server. Then the operator/user on the server clicks on the second slide and the laptop would now see the second slide. Is this possible to do? If yes, then what technology to use? DHTML? or something else.
View 4 RepliesI have a datalist and gridview that have a image in a column.. when you click the imagebutton, its calls my method that updates a table. The page is posting during this event, but when the page is done, the image hasnt changed.. im sure it has to do with the datasource not binding during that click.. so where can i move this code to or can i simply bind the control during that click? Currently im handling it in the itemdatabound event.. which would explain it.. but where is the correct place to handle this logic?

View 1 RepliesI create my own litte ViewEngine, done many things that works great, but now I want something to implement, but I don't know how.
I want the final Response Content when the controller is executed and the view is executed, manuelly manipulate and than send to the client.
I have two Examples for it.
First I have an AssetManager, he collects all Css files and JavaScript files, given by components, the view, classes and so on.
And this collected links I will insert with String.indexOf before the "</head" tag.
The reason why I want do this in the engine and not with a line like this in the head part
[Code]....
Is that I want so save me the work to do this every time on each project in the master page and maybe in single views.
A second usefull idea is, I want to write my own litte trace component, and I want so write the generated content before the "</html>" tag.
where I can manipulate the content before sending it to the client, and this in the engine?

View 1 RepliesI am using JQuery for all of my client side validation and Asp.net validator controls for all of my server side validation. I am using an errorlabelcontainer to store the client side validations in a summary at the top of the page, which is the requirement. All works well. My problem is, I want to display the server side asp.net errors in the same errorlabelcontainer OR display all of the client side errors in the validation summary. Either way, Both errors need to be in the same place/div. Any ideas on how to do this? I thought of maybe using the asp.net validation summary as the errorcontainer in JQuery, but I cannot find the summary. This is what I have right now.
$("#aspnetForm").validate(
{
onkeyup: false,
errorLabelContainer: $("ul", $("#FormErrors")),
wrapper: "li"
});
