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 3 RepliesI have been trying to get the Re-order list to work using the following tutorial (but in VB instead): [URL] The list is displaying properly, but none of the items are moveable. My code is pretty much exactly the same as the tutorial.
View 1 RepliesI'm using Webservice which will return the data from the database through datatable and I'll convert the datatable into byte array. In front end, I'll reconvert the bytearray to datatable and used ajaxloader to display it in the form.. It is dynamic loading. So, for each click, it is taking 10 seconds to retreive the data regardless of the size of the data. So, I used static datatable and I've loaded all data in that datatable in page load event. But, no reaction. It is taking only same time. Even, there is no data to retreive, the ajax loader is going on loading for 10 seconds. Problem is with Ajax or my webservice??
My Code for listboxclick event
protected void listboxcity_SelectedIndexChanged(object sender, EventArgs e)
{
string sqlvalue = string.Empty;
//Thread.Sleep(200);
for (int i = 0; i < listboxcity.Items.Count; i++)
[Code]....
I would I have dropdownlist with no items
And after the page starts I would like to kick a web service that returns 10 items at a time to fill the list unlit it is completed without lag on the web page.
I could I go and execute my own web service call the set those values, but I can have that run in the background to avoid interupting the User's expereince?
Do you know of a library/httpmodule for logging slow loading pages (perhaps for a specific treshold) in an ASP.NET environment?
Google did not yield any results.
It would not be too hard to implement on my own, but why re-invent the weel.
This is a continuation on this question:The problem is simple. I need to call methods from a REST web service which controls several tables. One table is a snapshot table which contains records with huge XML files. Each XML file is basically a backup from another database. This backup XML is then sent to customers who use the data as read-only information in another product. Basically, the data in the XML are lists of companies, products, business rules and whatever more. And no, those customers work offline most of the time, so they cannot get the data live.Walking through the list of snapshots is tricky: XMLData.Snapshots.Skip(N).Take(1).First(); but it works very nice. It's the answer of the previous Q.But there are three other lists of data that I need to walk through. These are called Changes, Errors and Messages. They contain (1) changes to the data, (2) errors that occurred during modifying the data and (3) generic messages. All of these records are linked to a snapshot record. Thus a single snapshot can contain multiple changes, errors and messages.
I still cannot access the server code but since there's a REST service wrapped around an entity framework exposing most of the functionality, I can still use that service. (And that service is only accessible internally, on the Intranet. This is basically what I have to work with. And while the lists of changes, errors and messages are relatively small, the snapshots are still huge.
The problem is that I now want to generate a client-side report of the changes, errors and messages, but without grouping them by snapshot! They need to be grouped by date. But each record also needs to show the title of the snapshot, which causes me some incredible headaches...When walking through e.g. the Changes with the regular foreach instruction I can load the Snapshot data by using XMLData.LoadProperty(Change, "Snapshots"); but since the snapshot record itself is generally about 300 MB, this just slows the whole thing down to a crawl. (There are tens of thousands of these records in total!) So I need a faster solution, without having to modify the server code.
Yeah, okay. Modifying the server would be the proper way but that's not possible. It's in production and this list isn't important enough to require an upgrade of the server. Basically, I'm not allowed to modify any server-code for now. (But they still want this list.)The application I'm working on is something that just needs to run once per week or per month. But with the current amount of records, I estimate it would take more than two days to finish. The data itself will be updated a few times every office day and snapshots are created every week or so on the server. Errors can always be generated when users start browsing the site which maintains the data but in general, there will be about 50 changes and 4 errors per week, plus a few messages when the server goes down and up again or when snapshots are generated.
Are there any javascripts or other method which can decrease loading time of google maps? Google maps are added by iframe code.

Can any jquery plugin be useful for me?
I am facing problem with images loading time. In my form I have image server control placed in repeater control. The repeater control every time binds atleast 300 images. When we want to see all the images at a time the page is taking lot of time(atleast 3 to 4 mins) to display. But I need the page should be loaded fast.
The image url is from physical location.And the information related to image is coming from database.
I am using .net framework 3.5 and C#.net as language in asp.net web application.
I'm about to build a web application(not web presentation) which will load its content through AJAX (jQuery) into a specific div. There will be a menu above the div and when a user clicks on an item from the menu, the appropriate page will be loaded into the main div.I'd like to know if there are any cons and pros of choosing this pattern for a web application.So far I'm avare that the browser back button and history/url will be gone.
View 2 RepliesI am writing an 3-tier enterprise asp.net web application which needs to be very lightweigt to lower the bandwidth usage. I want to speed up ASP.NET web page loading, I have minified all js and css, used AJAX, used less images in page, used paging for grids but still the overall response page size goes to nearly 1Mb because of viewstate hidden fields.
Is there a way to measure the time elapsed for a web page to execute?
And if so, is it safe to use that figure to estimate the speed of the web page as the number of users grow and the database grows. Ie: if the page currently takes 1 second to process through x amount of rows in the database, to estimate it would take 2 seconds with 2x rows?
I started using url routing for my web application. It's a dynamic website and it has more than 50k pages. It looks like now it works slower. how to optimize it, to improve it and make it more efficient?
View 1 RepliesI have a checkboxlist that gets data from my database and displays a list of items.
Item 1
Item 2
Item 3
I know how to get the chosen items, but i'm not sure how to get them in the order that they were chosen. This is my code to get the selected items.
[Code]....
So if I choose Item 3, Item 2, and then Item 1, when I display them on a label, the order is always Item 1, Items 2, Item 3. How can i preserve the order of the chosen items?

I would like to set cache- control on a folder of images in a web application . In that way i can cache the images and the web pages will load a lot quicker . I can specify this in IIS by putting a ISAPI extension , but how can i do the same thing in asp.net application, ie create that setting in IIS when the application first starts up .

i want to display the orders alphabetically.
I have a DropDownList inside the EditTemplateItem (if the user clicks edit) in a GridView.The DropDownList receives all available rows from the database. My problem is,if the user clicks Edit in the GridView to edit a row and opens the DropDownList Box the original item is not selected but the first one.That means the items are sorted. Have someone an idea how I can solve this issue that the right item / the original is selected if I change to edit mode of the grid view?
View 2 RepliesI have update panel on the page to avoid postback and placed a dropdownlist control within that update panel. DrodownList is filled with Category names and also it's autopostback set to True.
Now whenever dropdownlist index change's on select, untill page loads complete data it should show mesage as "Loading.... in center and middle of the page and background should become bit transparent". And when page load completely with data then that background and message should get disappear.
Is there any way to load [main] menu items in run-time? for instance using WebServices? My web application's main menu is so big and takes a long time to be loaded. So that, i want to load its items on demand. I want to load the sub-items of the menu item user is hovering.
View 1 RepliesI 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.

so i am looking for all kind of tips to increase ajax asynchronous postback speed.
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've made a website online that allows customers to place an order. I would like the information customers input on the website to show once the customer clicks submit to confirm what was entered.
