Jquery - Load And Show Data Asynchronously?
Feb 9, 2011
I am using ASP.NET and SQL Server. I would like to load data from database asynchronously and show data which are partially loaded immediately.Suppose there are tons of records in a query result. After 3 sec,It loads 20% then I have to process and show 20% data immediately, not waiting for complete response. I know $.Ajax in jQuery to load data async. Is it possible to process partial response, Not wait for complete response and show it immediately.

On the home page of my site I want to display a lot of products which have images which are quite large. Currently the page is taking so long to load that it is actually timing out and the page fails to display!
In MVC, or just ASP.NET in general, how can I load an image asynchronously? Basically what I want to do is display the details of the product and just display a small loading image e.g. ajaxload.info. until the image is loaded.
I assume this is going to require some javascript/jQuery...

Here is the situation. I need to hit ~50 servers and grab some data from a file. I then want to display a few rows for each in an ASP.NET GridView control.
I tried doing this with Threads/ThreadPool and successfully gather all the data in session.
What I'd like to do, and what I am having a hard time figuring out, is update the grid for the user after each server is done loading.
If I put the databinding code in the thread, it will only display whatever has loaded by the time the response is sent back to the client. If I take it out of the thread, I'd have to wait until all threads were done to send the response, and that doesn't do what I want.
I seeing some stuff about Asynchronous Client Callbacks, but I'm not sure if that's what I need to be using. I have no idea how to manipulate a GridView from Javascript.

I have four repeaters, that are all independent to each other. They all bind via web services on page load and then display the results.
There is a noticeable delay however and I would like to know how to achieve the following if possible.
On page load I want to begin asynchronously binding the repeaters so that as soon as the first one is bound, its result display and then the next starts binding.
I looked at update panels but from what I have read they do not have a page load trigger.

I am using a third party service for location time(zonal).If I pass latitude and longitude of the location with service URL it returns the time of that location in XML format.But the problem is some of the time this service gets too much slow so because of that my home page gets stuck because its a synchronous call of that service.here my code-
string TimeZoneUrl = "http://ws.geonames.org/timezone?";
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(TimeZoneUrl + "lat=" + latitude + "&lng=" + longitude);
XmlElement root = xmlDoc.DocumentElement;
XmlNodeList nodes = root.SelectNodes("//*");
How can I make this a asynchronous call?

suppose my page content is huge so in my asp.net application i want to show busy icon with percentage downloading the content in client side. i saw many flash and sliver light site that they show busy icon and also they show percentage that means how much content has been loading in client machine. how could i achieve this using JQuery and when page content has been downloaded in client machine the busy icon goes out and actual page content will display.

heavy operation which takes long time to be completed in my asp.net application. I don't want to run the entire operation in one request which may result in a TimeOut error. Instead I want to invoke the operation in a separate thread and poll for the result every x seconds. How can I do this?If the operation gets completed I need to register a script in the ajax postback to hide the loading panel and show the content. However I'm not able to register new scripts and invoke it during ajax postbacks.

I have an ASP.NET (3.5) web page which calls a few web methods (SOAP based) using jQuery's .ajax method. The web methods implement 'ScriptMethod' attribute and return JSON data. The web service file (asmx) is local to the same project.
I noticed these web methods execute synchronously on the server which means they run sequentially and affect performance negatively, some methods are waiting, when some of them are slow.
I read this article and I am not sure if I understand that WebMethods which implement Scriptmethod can run synchronously only (they implement IHttpHandler not IHttpAsyncHandler).
If this is true, I might have to change the design. I am looking for other designs, maybe like using WCF, where the browser can call webmethods using JavaScript and the web methods run asynchronously on the server.

I'm working on an ASP.net application in which I've multiple web parts in a page. Each web part has its own data source pulling data from them and showing it. When a user tries to load the page I want to load the page instantly and asynchronously render all the web parts with the data.

now when i type something in header Search cell , it shows the data of first page index only , it won't show me data from 2nd page index .. here's my code :
protected void PhasesTempGrid_OnDataBound(object sender, EventArgs e){
GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
for (int i = 0; i < PhasesTempGrid.Columns.Count - 1; i++) {
TableHeaderCell cell = new TableHeaderCell();
TextBox txtSearch = new TextBox();
[Code] .....
My gridview is in update panel therefore i did this in .js script :
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function () {
$(document).ready(function () {
$('.search_textbox').each(function (i) {
[Code] .....
Here's my code structure for gridview :
<asp:UpdatePanel ID="ConstructionActPhaseUpdatePanel" UpdateMode="Conditional" runat="server">
<ContentTemplate>
<asp:gridview ID="PhasesTempGrid" ClientIDMode="Static" OnDataBound="PhasesTempGrid_OnDataBound" allowpaging="True" OnPageIndexChanging="PhasesTempGrid_OnPageIndexChanging"
[code]...

In my master.page I load a Web form:
<script type="text/jscript">$("#LoginInformation").load("LoginInformation.aspx");</script>
But when I have a ListView or DataView, etc... with a pager, I get problems when I click on 'next page'.Then I get the error: Validation of viewstate MAC failed. When I don't use Jquery's load function, I don't get an error.

I have a requirement to show a list of rows (from a datatable resulting from a call to stored proc) in a pop-up window. I'm wondering if I could do this with fancybox? The situation is that on my main page, there is a Gridview. One column has a linkbutton and when the user clicks it, they want to see a pop-up with a grid or table of more data related to the row they clicked on.

Basically I have a site where I want the user to input something, have it go to the server for processing and then return it asynchronously, load the contents into a div and then fade it in with jQuery. What is the best way to the do accomplish this?
Currently here is my "solution":
$(document).ready(function () {
$('#output-box').hide();
$('#form1').submit(function () {
$.ajax({
type: "POST",
url: "Default.aspx/ParseData",
data: "{ $('#txtInput').val() }",
success: function (msg) {
$('#output-box').text(msg).fadeIn();
}
});
return false;
});
});
It doesn't work - just returns the contents of Default.aspx. So how do I properly send the contents of #txtInput to the ParseData function in Default.aspx.vb? Also, is this the best way to accomplish something like this? Should I even need to use jQuery to send the data, or should I simply call the function and have it grab the data server-side, put in the information in the result div, and then show it using jQuery?

I'd like to achieve the following effect using ASP.NET MVC and JQuery. I've got a drop down list displaying a list of Countries. I want to make it so that when I change the value of the country, a new drop down list appears below it, showing a list of companies whose country of origin is the particular selected company. The thing is that I do not want to rely too much on controller actions because I'm using it in a Template Helper which is a "headless" view. Can I bind it somehow?
