i am trying to increase my web based game movement system speed as much as possible.
i am using ajax asynchronous postbacks for moving on the map. (if you wanna check address [URL] )
so i am looking for all kind of tips to increase ajax asynchronous postback speed.
i have 100 buttons and 101 textboxs, button run scripts and some of them run by code like this:
[code]....
i meaen i want it run on client side only , before i submit by another button, but the problem is it spent more than 2 second to get value
from textbox1 to textbox2 in this case( because i have 101 button run like these), i know that it need time postback to server. i could not use return()false because if i do like that the value from texbox1 will not add into textbox2, 2 seconds is not reach my golf.
I am working on finance domain, we are using many sessions and viewstates for store values and data. Our clients want fast speed of our website. We are using grid/repeater/datalist and chart controls for show data.

I have a website that enable the user to upload pics to server (uploaded pics sizes are 300x400 and approximately 270kb). In my app. I am having another page that lists the pics and I am using there an image control for that purpose. The Image control sizes are 80px width, 60px height. My question is how can I improve the download speed by minimizing the images ? Do I have to create a thumbnail for each picture the user upload?
View 4 RepliesThere are various website speed test online tools available. Few of them are listed on: [URL] I tested my website using iweb and selfseo. My website is showing 0.03KB Average speed per KB everywhere. Even google also is giving same kind of results.I tested the site using Page Speed and YSlow. I have already followed most of the recommendations suggested by these tools like efficient use CSS, contents across the domains, caching, compression and all. But still I am getting the same average speed per kb. Page speed is showing around 85/100 as my page speed score, so I guess I have optimized my site a lot. My questions here are:
1. What are the other factors affecting the avg speed per kb of a website?
2. How to improve the Avg speed per kb?
3. Is there anything related with the Server Software and Hardware that I have to check?
Note: I tested by uploading a plain html page with simple text "Hello World", but the avg speed per kb is the same for this page as well. Same is the case with the rest of the pages.

I have an asp.net page which has 4 grid views connecting to mysql database for data population. The average response time for a round trip to the server is 20.55 seconds. That is way too much time. I have since applied the HTTP Compression GZip to improve the speed,I don't see any improvement in load time. Ive also used pagination, but no effect.
View 3 RepliesIs there any way can let me set a textbox's value before the asynchronous postback. but I don't want to add a handler for a control which caused that asynchronous postback, because there are too much control can cause that. I want to know if there is a client event would be caused before the postback.
I tried the event initializeRequest of PageRequestManager to do this, but it did not work, it seems like the request has been generated when this event was executed, the value i set in this event for textbox did not be sent to server.
here is a page I used to test

I have textbox in which pincode has to be entered and it checks with database and gets city and state from database and fills data in other 2 textbox.I have kept asynchronous postback trigger on textbox textchanged event. After reterving data from database i set focus on other textbox of STDCode.But the problem with ie7,ie8 browser is that the focus comes on control but i can't write anything in stdcode textbox untill i move to another textbox. When i come back from another textbox i can write in stdcode textbox.Problem gets occured only in IE7,Ie8 browsers only.Here is design file of that page.

I am building a website in which all of the site layout is in Master page and the content of the site is in the inherited pages. I have various links for navigation in which i simple use Response.Redirect to transfer to different pages. Now the problem is that I want to put the content place holder inside Ajax Update panel so that the postbacks are Asynchronous and I want to show the postback by an animated image inside Update Panel progress control. The problem is that I am unable to achieve this result and the entire page is posted back and rendered again. I have placed the content place holder inside the Ajax control toolkit's Update panel but it does not work. Is there any way that I can change the content of the content place holder to a new page with asynchronous postback.

I have same problem, can anyone write a code project exemple
During Asynchronous postback (Ajax) will Page_PreInt() ,Page_Init(),Page_Load() events fire again?

Well I have a strange problem.I have a page with 2 DropDownLists on it and a custom web-user-control. The custom web user control has an UpdatePanel within it, and an Ajax Timer control within the UpdatePanel to periodically update a listing of stuff.When I "drop-down" one of the DropDownLists and hover over (not click on) an option while the Timer control within the UpdatePanel asynchronously posts back to the server, the DropDownList "autopostbacks" to the server!
I'm trying to figure out why an asynchronous postback would cause the DropDownList to act as if I selected/clicked on an option so that I can find a way around this issue.Now it's really simple to reproduce this problem. Create a Web User control called "TimerUpdatedListing"...this is the ASPX code markup for the web user control:
<%@ Control Language="vb" AutoEventWireup="false" CodeBehind="TimerUpdatedListing.ascx.vb" Inherits="MyNamespace.TimerUpdatedListing" %>
<div style="width: 150px; height: 150px; overflow: auto; border: solid 1px navy;">
<asp:UpdatePanel ID="anUpdatePanel" runat="server">

I have a page that has 5 sections. Each section takes about 1 second to render.
Page_Load()
{
RenderSection1(); //1 sec
RenderSection2(); //1 sec
RenderSection3(); //1 sec
RenderSection4(); //1 sec
RenderSection5(); //1 sec
}
I would like to speed up the loading of this page. But at the same time make sure that it don't slow down performance of other parts of web application and also do not crash the IIS.
The are several approaches:
Use AJAX requests. Needs to be MVC style requests to Controller or Web Service. Using UpdatePanel around each section will not work - since if I try to submit refreshes to multiple UpdatePanels at the same time using approach here: [URL], the last request will always win: [URL] Use ASP.NET threads described in answer to right way to create thread in ASP.NET web application. So I would use a separate thread for each call: RenderSection1, RenderSection2, etc... Move the logic that takes up time, usually DB requests, into Application Service class in another DLL or External Web Service. Something like
OrderDTO GetDataForViewOrder(int orderID)
{
}
and use multiple threads in that DLL. This approach seems to provide the best scalability, but also introduces UI details into Application Services layer.
I did the tutorial on this site for the auto completer control. It can be found here[URL] to see the code.
It uses a page method that has the words in a string array for the auto-completer. It works but it's really slow. There is a delay of a half second or so before it appears. Even when I have cache enabled it's really slow. The array only has 5 or 6 words in it. I can't imagine how slow it would be with a much larger list. Which is how this would really be useful.
Is there a way to speed this up? I know I've seen these on the web that worked better. It seems like if this were done using a service that it would be way too slow.
I want to implement the following page by Asp.net version 4.0 and ajax but I want to have loading by order like loading item 1 and 2 and so on. I have container or web part but mostly container like simple asp.net panel. how I can implement it ? I used updatepanel and update progress but it doesn't work that I have expected before.

View 4 RepliesI am relatively new to asp.net. In My asp.net website, i have a method GetData(int id) which is called Repetitively, depending on id count, GetData is desinged to get data from sharepoint and sql server both. if the Id count is high say =10, my page load time increases because GetData is called 10 times and the page load time keeps adding up. so I want to ask, is there any way that this GetData() be called asynchornously or by the use of some thread, so that my page loads faster.
View 2 RepliesSince i am fresher to .net, i m unable to handle asp.net. I have call asynchronous ajax call using XMLHTTPRequest and also use QueryString to filter Employee details.
I have following files:
1. Default.aspx code
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Task2._Default" %>
<%@ Register TagPrefix="uc1" TagName="SearchResult" Src="SearchResult.ascx" %>
[code]....
3. Ajax.aspx is empty in design
what should be the code in Default.aspx.cs when u take some text in textbox to search, OnClick of "ok" button there should'nt be any postback.
first i'll describe my problem:
I have payment form with a clients dropdownlist that is populated from a database on form load with:
value field = clientIdtext field = nameId
<asp:DropDownList ID="selClients" runat="server">
</asp:DropDownList>
When user makes a payment, it's necessary to chose a client from selClients, and so i get the clientsId value and build my insert SQL query.
Until here, no problems.
The problem with my UI has started since i had a lot of clients been registered: My dropdownlist became huge and it's taking too much time to load it's contents on page load. Also the dropdownlist area is taking a large area from page screen.
So i tryied a solution with jquery autocomplete plug in. I put a textbox with autocomplete for client name and another hiddenfield to receive the clientId when user select a item.
That solves both problems:
No more large amout of data loaded on page loadThe dropdownlist doesn't take a large area from page screen
But it gave me another problem!
With a textbox, there is a possibility for wrong input client name. So if i don't have a valid clientId in hiddenfield, it will generate a database INSERT exception because it doesn't respect the client table constraint:
payment table REFERS client table
I'm trying to find kind of dropdownlist where the user can type text with autocomplete. Like this, the user will be able to select only data within the possibilities of the dropdownlist and i always will have a valid clientId.
