I have noticed that many new modern websites (and templates like themforest templates) are being built without any page flicker.What I mean by page flicker is that when you click on a link the hole screen flicker and then the new page is retrieved and viewed.Here are some examples of these new sites (templates) that do not have any page flicker.
I have an AsyncFileUpload with an image control to show a preview of the pic that is uploaded. Everything works fine, however on the postback from the asynchFileUpload the page jumps to the top of the page and then after a second or two it goes down to the proper scroll position. What can I do to avoid having the page jump to the top and then back down again on the postback ?
I want to create a searching work to fill the gridview detail acc to seach params.. When we enter text into search textbox it fills the grid, that works filne without postback. After this i have to fill the form values accroding to link clicked in Gridview. I uses the updatapanel in grid like
When the grid fills it doesnt fill my form... why it happens.. i used the Updatapanels multiple as well.. If i use the Updatepanel in whole.. it may flicker while filling in the form values.
This upload is working. But why the page is getting refreshed? this is not partial post back and instead it 's full post back. i have read the articles for the fileuplaod with issue inside the update panel. is there any way to achieve this asynchronous upload on button click?
I don't want to use the Ajaxtoolkit Asyncupload because that will upload (Ref : [URL] ....] the moment when we seelct the file itself which i don't want to do that. i need to do on the button click event.
I have block of code that consists of a textbox a button and a dropdown. The text entered in the text box filters the dropdownlist when the user clicks the button. The Ajax works great when it is in a simple page but if I put the same code in a User control I get flicker.
I have three cascading dropdowns on my web page and they work fine. The issue I am facing is that there are other controls on the page which cause a postback and with each postback the cascading drop downs are being re-populated (service methods are called) which is becoming a performnace issue.
When an asynchronous postback happened inside update panel, another postback happens also for MasterPagenot only update panel embedded page .I want to prevent this MasterPage postback . is this possible ?think like i have a MasterPage and another page which is test.aspx which is content page of MasterPagei have update panel at test.aspxwhen asynchronous postback happens at this test.aspx update panel it also loads MasterPage Page_Loadi want to prevent this (it should not also load MasterPage Page_Load)
I have a page with two updatepanels both using a timer's tick event to do various bits. The script manager is set to conditional updates and the panels are set up to use specified triggers but when the tick event fires for either the page flickers and the scrollbars reset to midway down the page. This renders my application unusuable.
It works fine in Firefox but in IE 7 fails doing the postback sometimes. Is it just a problem with my browser? The partial postback inside the update panel works great in both browsers, but when I hit the button outside the panel, the complete postback doesn;t work in IE....

I have a dynamically generated image placed inside an update panel. The image is generated with the Generated Image control (see here for more:
[URL]. This is basically a specialised httphandler linked to a normal asp:image, where the image src is generated dynamically. In my case, I use some GDI+ to dynamically generate the image, based on values from a database query.
The problem I have is that the image does not update when the update panel updates. The image does, however, update if I manually reload/refresh the page (i.e., hit F5). Why is is that some code fires during an update panel update, and not other code? And, more importantly, what can I do to make sure the image generation code does fire during the updatepanel update?
I have a Username and Password field on webform and a Submit button.Username ia validated through database on button click.Each time when i click on submit button and if Username already exist then my password gets to be removed due to postback.Please give me some solution so that when i just defocus my username field it will automatically check and display message if it exists.Please donot give Textbox ontextchanged event with update panel in conditional update mode because it will not work for me because i am using devexpress tools on my webforms.
so I got the following page - student listed with 6 buttons to indicate a lunch choice. Clicking the button will update the DB immediately - so a postback happens and lots of screen flicker.
Where do I put update panels in this messy repeater in order to make just a row "redraw"? I broke the code into two parts so you can see the StudentRepeater in the second code window.Also - note that the lunch counts in the labels on the left will also update from the DB. Does that go in it's own update panel?
I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)
I use AJAX tab panel for my web site (ver.1.0.2) with VS2005. Previously I use large page and now i it change to tab panel. The problem is when I change the source view to design view it automatically update the content of tab panel and show the 'error creating control' and sometimes it not. So I'm having difficulty on designing that page because always I have to keep the backup of the page.
Gridview binding data from database without doing postback on the select of item in dropdown.i know it is possible through ajax update panel but for some specific reason it can't use it.And i think that gridview is a server-side control and if i implement it by using table structure , jquery ajax and web service then it will loose all gridview properties of edit, update and paging etc.
