How To Avoid UpdatePanel Scrolling On AutoPostBack
Mar 1, 2011
I have an ASP.NET FormView within an updatepanel. I'm auto-saving the form by setting AutoPostBack=true for each of the items within the FormView.
This means the user can click a few elements in quick succession and fire off a few async postbacks almost simultaneously.
The issue I have is that the user is able to keep scrolling down the form while the async postbacks are not yet complete. The browser always scrolls back to the position it was in at the first postback.
Page.MaintainScrollPositionOnPostback is set to False.
I've tried all sorts of things in ajax and jquery with:
I have two textboxes insie an updatepanel, the same update panel also has a trigger from a Clear Button from the other update panel. The first Textbox AutoPostBack is set to true. The first time when the textchanged event is fired, everything work as expected--the labels got populated, the focus is set to the second textbox. However after I click on the Clear button, i entered something to the first Textbox, its TextChangedEvent fires--the labels got populate, the focus seems set correctly to the 2nd textbox, but I cannot enter anything to the second TextBox. it seems like the form is not active--when i hit tab, I expect the focus move to next control, instead it moves to the URL box. Turn off the AutoPostback then put a button next to the first textbox will fix the problem, but I am wondering if there is other workaround to keep the AutoPostback of the 1st textbox?
I've got a TextBox with AutoPostBack="true" and OnTextChanged property set.
The textbox is located inside a Repeater, which in turn is located inside an UpdatePanel.
Problem is - whenever the TextBox postsback, the whole page gets reloaded, instead of the UpdatePanel only.
Here's how the thing looks:
[Code]....
Interesting thing is, if I take the TextBox out of the repeater, it refreshes only the UpdatePanel. So is if I put a Button inside the repeater - only the UpdatePanel gets refreshed. But whenver I place an AutoPostBack-ing control inside the Repeater, the whole page gets refreshed.
I am using an asp.net autopostback enabled dropdown list. Here i want to restrict the autopostback property fot the value "Select" in the ddl. I have used javascript for this purpose. but not working.My code look like this.
I have two update panels and one javascript control.
When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.
However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.
i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.
I have a grid at the bottom of my website. There is an image button that addas a new row to the grid but as i click the image button the scrolling moves to the top disturbing the focus of the page. How can i stop the scrolling at one position only.

I am using jqplot to show candlestick chart and the data is from xml.I retrieve data from xml and put it into array and then jqplot creates a candlestick chart from that.but xml file contains lots of data so in chart values are over lapping (with fixed width). we make graph of lets say 10% of data and place a scrollbar and on every tick of scroll bar we rebuild graph with next data or there already exists any such functionality of scrolling graph/chart in jqplot
wanted to create some scrolling text on a page dictated from a sql query, in html days i used marquee but this didnt seem to work, and nor do i know how to fit it into a sql query, i was a select query attached to a label would do the job,
At first glance it seem to be an easy solution, and I really thought that I would be able to find it with a simple googling, but I couldnt!
I have this web-based chat application written in ASP.NET using C# with code behind and Ajax. I would like to scroll down automatically my "chat_area" DIV after to update it with new contents.
I have found the following code that supposed to be enough to do the task:
I've got one long GridView control on my website. The problem is, when I scroll down this GridView and select a row the selection occurs, but whole GridView is scrolling back to top and lost its current position. I am also fixed header of my gridview but when i put stop scrolling code in that page, its disable my fixed header.
I am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
for some reason when i view it in IE the page scrolling is extremely choppy. When i view it in firefox or safari the site is really smooth.I am not sure if i added somthing which made IE choppy because i do not remember it being choppy.... but i never really paid attention until i started to notice it.Is scrolling the site in IE choppy for you also?I tried to remove all the jquery and java - scripts i had, still choppy when scrolling. I'm not sure whats going on? The website is quite image heavy, even backgrounds are quite big, however firefox and safari have not problems... is it a IE chaching problem?
I've got my GridView inside another Panel and I got scrollbars but GridView is to big even with paging. So user needs to scroll down to scroll horizontal (to see horizontal scrollbar). How can I add any horizontal scrolling trick for my GridView in the Panel. Maybe something from javascript ? My js knowledges is still being poor. I really hard thinking on what that could be, maybe floating horizontal scrollbar?
I have a ASP.NET web page that contains many textboxes. Each textbox has a tabindex set. When I am tabbing through the textboxes, if i decide to click on the scroll bar to navigate the page up/down then return tabbing the tab order is reset. The tabbing begins at the start. I am using VS2008 and the browsers causing the problems are IE6 and IE7. This does not seem to be a problem in Firefox.
How can you have a fixed header on a DataGrid or GridViw and allow the grid to scroll? I'd like to avoid a solution that uses another separate table for headers.
I have a page with three tables, three charts and some other stuff. When I scroll up or down on the page it tries to jump to some other places, scrolling is not smooth. After a few minutes I also get this error popup: Error: Sys.WebForms.PageRequestManagerServerErrorException: The underlying connection was closed: An unexpected error occurred on a receive. The same behavior is noted on all pages with charts.
