AJAX :: Update Panel Fast In Debugger But Slow When Published?
Jan 29, 2010
I know it's not the best practice to do, but unfortunately I created a page with multiple large dropdown lists and have them inside an ajax updatepanel. I found some work arounds using siderite's ajax updatepanel adapter:
http://fastlistadapter.codeplex.com/.
The performance is very good while I am debugging on my machine, but when I publish the site and post it to a win 2003 server the performance drops off almost as bad as when the fix isn't there.
I understand that using a 3rd party fix really isn't supported by most, but is there any obvious reason why debug performance would be much better than published site performance on the same exact code?
I have, what i think is a very simple updatepanel setup. I have searched and found other similar issues, but they date back to 2008 and 2009. Is the fix provided back then the only known fix now? Is there any other fixes or things.
Using VisualWebDeveloper 2010 on the development machine. All nice and fast.Using VisualWebDeveloper 2008 on the server. Server runs on Windows Server 2008 and has IIS 7.
It looks like that when 'table', a datatabe filled up in C# code behind, is getting longer, then the server (whether running the website on IIS or on the local host of VIsualWebDeveloper2008) is really slowing down. Checked it in debug mode and traced it down to
Adapter.Update(table);
Are there any know issues? Could it be that there is incompatibility between different version of SQL server or something like that? The update works, it is just awefully slow, but only on the server.
I'm writing an app in which user can register. While registering the one may choose several options and according to these regiester fields are visible or not and are required or not. I came up with an idea that all fields will be in in the updatePanel and when users changes registration options I would set visibility of these fields on the server side.
It works but incredibly slow and whats more on the FF I have the given error:
The state information is invalid for this page and might be corrupted
3 checkboxes with other fields are in the updatePanel
Each field is in dl tag with runat="server>
I had to do it like that cause for "required" option I simply add css class to this dl (need in in javascript validation. If field should be visible I set visible="false" for given dl and then that field for example FirstName with title and so on isn visible after postback.
Am I doing something wrong ? Why does it take so long (~4 min on localhost) and in firefox it doesnt really work (when I use debug I think that process completes without errors on ff, I dont understand that at all :)
If update Panel is so weak what would be other option to change visibility and adding required class to all dls. Logic is quite complicated and has to make query to DB so simple javascript would be quite tricky.
Oh and I'm using ASP.Net and cant upgrade on this project.
when I access any page of my ASP.NET MVC website first time, then this first request is slow. It needs about 4-5 seconds to load. But every following request to any page is fast.When I wait some minutes or a hour then every first request is slow again. Every following request is fast.
I think that IIS 7 is compiling the code and keep it in memory. After some time it will delete it from memory so it needs to compile it again.What can I do that every first request is as fast as every following request? (Without precompiling my source, if possible)
I have made an asp.net web application using VS 2008 to show crystal reports. I have used CrystalReportViewer control to show reports.
The table (sql server 2005 ) from which I have to fetch data has approximately 400000 records. I connect to it using OLEDB ( Microsoft OLEDB provider for sql server )
We recently migrated to v4 of .net. We are running iis 7 in integrated mode. When the site first starts its slow. I get that - it compiles for the first time. The odd thing is then we will go to certain pages and it seems to compile again. The next time i go that page its very fast. Nothing exceptional with the second page - but once that is hit the rest of the site is fast.
Let's say you set maxRequestLength to the max number (2097151) (units are KB) and use the following code for your OnClick event for your submit button:
int int fileSize = FileUpload1.PostedFile.ContentLength;
if (fileSize < 2000000)//units are bytes Label1.Text="too big"; else { FileUpload1.SaveAs(saveItHerePath); Label1.Text = "Upload success."; }
Why when a huge file is attempted does it take a minute to get to the OnClick event on the server? Because if maxRequestLength were set to that value 2000, it would immediately choke if you tried to upload a 500MB file. What is going on here? What are the best practices for using the FileUpload control? Is there a better alternative way of uploading or checking for file size?
We have two update panels on our webpage. Now first update panel is having button cancel. While second update panel is having a file upload control.
Now if the user uploads a file that is going to upload in about 2 mins, and in between, say after 30 seconds the user clicks the cancel button, the upload taking place in update panel 2 should stop.
My application runs quickly when debugging locally, but slows down to an almost unusable state once published. Oddly, the published version seems to be grabbing data very quickly from MSSQL - it's the part where I'm updating datatables and gridviews that is very slow. For example:
i have developed an ERP in asp.net 3.5. The problem is that when published and as well as during development, the execution speed of page is very slow. I have off the compilation mode in web.config and also get all the data in page load and then filter it using Dataview rowfilter property but i can't get much better speed.
I have one update panel inside updatepanel i have one dropdownlist .When i change dropdownlist value so as per value button1 which is out of updatepanel not visible =true or false as per dropdownlist value.
I have two applications(A,B) both are developed in .NET3.5 and used LDAP services.Application-A in one screen we are fetching users with role "project Leads" and it is taking 10 min time
Application-B in login screen we are checking user is authenticated or not and it is taking 20 sec
Both the applications are using the same service then way there is a time span problem. Please suggest me what can I do to improve performance of application A?
I have a Gridview containing 10 columns and anywhere from 10 to 40 rows and each cell contains either dropdown or input boxes.I also have a calendar control that changes the data displayed in the gridview.Right now I have an outer update panel around the entire gridview and then I have inner update panels around each control, so potentially 400 update panels depending on the amount of rows for each day.The individual control updates happen fairly quickly if I for example change a dropdown etc, but when I change the day and the entire gridview has to refresh it is painfully slow.On average 30-50% of the cells will be manipulated between change of date. What is best practise? Right now it is to slow.
i have my master page with one update panel working like a banner, so when the timer do tick every 5 sec
the image change. That works fine, but i have an update panel in my index page, this update panel works with some buttons that change the text inside the panel when click.
Now, the problem.
When i click one button to change the text and the banner change, the text returns to his default text. The update in master page is affecting the update on index page.
I have a panel bar..each time I press panel bar item I display ascx control with in update panel..but it lakes update panel loading time lot..how I can decrease that loading time?
I have an AJAX Modal Popup panel that contains a RadioButtonList, 2 labels and 2 DropDowns. I want to update the Labels and DropDowns when a radio button is selected. My attempt at this posts back which causes the ajax popup to disappear.
aspx called on image click: <asp:Panel ID="pnlModalContainer" runat="server"> <asp:RadioButtonList ID="rblTest" runat="server" RepeatDirection="Horizontal" OnSelectedIndexChanged="rblTest_SelectedIndexChanged"> [code]...
I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.
I have a formview in Edit Mode, within an update Panel all and these arewithin a Modal Pop Up extender.On clicking Formview Update button, I want an image to appear within the pop up.I have put the image within another panel1 and runat server.For some reason the image is not showing on clicking update button.
