AJAX :: TabContainer Occasionally Failing To Draw?
Mar 2, 2010
Okay, so this is one of those annoying bugs that happens sometimes, but not with enough regularity to really root out.
Fair warning that I'm still just toddling in ASP.NET, so I could be doing something heartbreakingly stupid. Here's the gist:
I've got a page with the bulk of its content inside of a TabContainer from the AJAX Toolkit. There are a few page elements outside the TabContainer -- mostly just header/footer stuff from the master page. Sometimes the page will load (either initially or on a postback) and the TabContainer will completely fail to draw, leaving a mostly-empty page. Clicking "Reload" in the browser almost always makes everything appear as usual.
What would make a TabContainer occasionally fail to draw? How can I go about debugging this.
I am using a bunch of SliderExtenders to morph the ASP Textbox into a Slider control. This has worked great. However, I noticed that 1/20 times, occasionally, the sliderextender fails to morph the textbox. So the textbox actually appears during initial page_load. However, you can still drag the slider around because it is also rendered beneath the textbox.
A subsequent page refresh fixes this problem until some other time.
As security of the return data is not a problem, I am Get enabling the HTTP response. On the client (browser) end, my code is as below
Everything works smoothly but occasionally on the web server's event viewer, I see the following error
"Request format is unrecognised for URL unexpectedly ending in /SomeWebServiceWebMethod"
After fiddling through the request headers using Fiddler, I figured out that if I make direct request to the webservice link, contentType header attribute is missing and that is what throws the error. There is a good post by scott guthrie explaining this. I am not able to replicate the issue and not sure what removes the contentType attribute from the request header occasionally.
the jquery is embedded in an .aspx page (a language i'm not familiar with) but is posting to a php script. i'm receiving emails properly but there is no data inside. am i missing something? i tried to bypass the variables in this example, but its still not working.
I have a website which uses the latest AJAX Control toolkit. On my pc, the website is loading perfectly well. The page makes use of a tab control and an update Panel - AJAX Control toolkit.Unfortunately when I uploaded the website online, on the shared web server, the website gives the following 3 errors (on IE) :
1) ASP.NET Ajax client-side framework failed to load 2) 'Sys' is unidentified 3) 'Sys' is unidentified
The page finally loads, however the ASP.NET Ajax controls do not load (Tab controls and UpdatePanel). The rest of the page loads perfectly well. I made some searches online, however still cant find a solution.
Facts:1. The site contains an Ajax Script Manager Proxy2. The web.config states that the site is not in debugging mode3. Tried to create a fresh new virtual directory and problem still persists. 4. On my Development machine the website is 100% functional.
Yesterday I upgraded to MVC 2 RC. I have several jquery ajax requests that worked fine prior to the upgrade. Sometimes they work, sometimes they don't.
I know the MVC team made changes to the framework to protect against Json Hijacking so that GET requests are not allowed (by default) and I have changed my jquery ajax code to use 'type: "POST",' and then adorned the Action Method with the POST verb.
Again, the odd thing about this is that it works sometimes and other times it doesn't. When it fails, there are no error details. The error code is 12030 or 12031.
At present we are using <ajax:TabContainer> to load tabs. I have 5 user controls inside <ajax:TabPanel>.
The problem is that all the data on these 5 pages gets loaded at once and increases the loading time as well as it is very hard to debug. Can we do lazy loading uisng TabContainer control? so that only the data of the current tab is loaded and when we click on the other tab then that's control data gets loaded.
m kinda new in asp.net ,i'm try to do a web form with 3 tabs but i want that the tabs will start from the right end of the screen and not from the left?is there a way to do it?i searched the properties list for such a thing , and i didn't fine it.
I have a page with the CuteWebUI upload control in it. The page occasionally locks up permanently, and by locks up I mean the whole browser locks up. Does anyone have any problems like this, or can anyone think of a general reason why this would be happening?
My company is running into a problem with a web service that is written in C#/ASP.Net. The service receives an identity key for data in SQL Server and a path to generate and save a PDF report for this data.
In most cases, this web service returns results to the calling web pages very quickly, usually within a few seconds max.
However, it seems to occasionally hit a significant slowdown. The web application calling the web service will generate a timeout error when this slowdown occurs. We have checked and the PDF does get created and saved to the server, so it looks like the web service eventually finishes executing. It seems to take about 1 to 2 minutes for processing to have completed. The PDF is generated using ActiveReports from Data Dynamics.
Wwhen this problem occurs, making a small change to the web service's config file (ie, adding a blank space to a connection string line) seems to restart the web service and everything is perfectly ok for a period of time afterwards.
Other web applications that are running on the same web server do not seem to experience this type of behavior, only this particular web service.
I have added the code for the web service below. It is basic calls to 3rd party libraries. We are not able to recreate this problem in test.
I created dynamic the tabpanel of tabcontainer, and the tabpanels change depended on the item which chooses from dropdownlist but the problem is tabcontainer keeping the last tabpanel and create another tabpanel and I couldn't remove them how I can rebulid the tabconatiner each postback
Having a strange issue with the TabContainer in the AJAX Toolkit. We have several views into a customer record system that we have built as ASP.net controls. These controls use UpdatePanels to load data asynchronously. We use jQuery and jquery.ui to place these controls in separate tabs on a single page. Which all works swimmingly. Lately, I've gotten a little tired of the jQuery tab hackish approach and decided to port everything to use the TabContainer. I want to be able to control the tabs as objects.
At first glance, everything works perfectly. I just slapped the controls into tabs in a TabContainer and everything looked great. However, for some reason, databound controls are losing their data. For instance, grid views vanish when I switch pages. A drop down control with an OnTextChanged event, loses its databound list of values upon post back. Something about the TabContainer -> Custom Control -> UpdatePanel -> Control that uses data binding heirarchy is throwing it out of whack and the debugger isn't shedding any light. It seems like control state isn't being stored. I don't really know enough about control state to know what to look for. Here is the markup for the TabContainer:
I am using MONDOR's MSCaptcha control in my ASP.NET 3.5 application, and everything seemed to work fine both locally and remotely, till I started receiving complains from rare users.I am using is for my web site registration, and as I see many people are able to register, I assume that the problem is rare.
However, I've heard two complaints from two different users that Capthca image is not displayed at all. They did not add any special blocks to browsers, and both tried several browsers and it did not work in all of them.here is my code for referrence:
