Web Forms :: PostBack - Scroller Goes Top Of The Position First And Loading Some Images When Select Some State
Nov 4, 2010
I have form where I am displaying States and related cities. it is displaying properly. I also used MaintainScrollPositionOnPostBack="true" too. But the problem is when I select some state then my scroller goes top of the position first and loading some images. [it shows me on status bar] and after this it it maintained the position. During image loading it takes 4 - 5 seconds and it's too much for me.
I have a web page that regularly refreshes on post back, and all of this works fine. However, a user has made enhance the page, which I need with:
1) There are 3 asp.panels on the page, which are scrollable vertically. When the page refreshes, the scroll position returns to the top. The enhancement is to maintain the position of where ever the scrollbar is on postback. How do I keep the scrollbar position on post back?
2) Within each of the panels are dynamically added web controls. These web controls contain gridviews, which are themselves contained inside div tags. These div tags can be hiddened and made visible by an image button. This hidden and visible state is actioned by some javascript on the page. Again, the user has asked how it is possible to maintain the state of these div tags on post back, i.e. those that are closed and those that are visible. Currently, the state is on postback for all the div tags to be visible. How do I maintain the state of the visibility of a div tag during postback?
I am looking for a scroller which auto scrolls to the end and stops and switches to manual navigation. I tried googling, there are thousands of scrollers but i need one with both autoplay and manual scroll funtionality. Where user can also switch to manual scroll with a single click while it is auto scrolling. something like this
[URL] But it must auto scroll and switch to manual scroll once user clicks on it or if the scroll has reached the end. I dont want it to slide i want it to scroll.
I have a web page in which i have some validation after textbox lostfocus but i want that If Error occurs then text box changes their position and as soon as user corret that error text box set it on its original position how can i do it
I have a page that uses AJAX updatepanels. On this page, we have some radio buttons with Autopostback set to true. The problem is that after the postback, the control was losing focus so that when the user would hit tab, control would be restored to the first control on the page and not the drop-down which fired the event. As a fix, I wrote some set focus code in the radio button's oncheckchanged event. This seems to have fixed the problem with the focus. The problem I have is that the browser loses its scroll position every time I click on one of these radiobuttons. Is there a way to maintain scroll position? Maybe there is another way to resolve my original problem of setting focus that will prevent this from happening.
Is there anyway to define the screen position after a postback?
Specificaly i'm referring to the vertical scroll position. Some of my controls are set to AutoPostback = True. Depending on their selected value it then reveals a hidden ASP.Net panel and some more questions.
Problem is that with each post back the page refreshes at the top and i have to scroll back down to my question. I can use the .focus() control, that's fine, but it doesn't work as perfectly as i'd like. Is there any way of defining how many lines or pixels the screen is already scrolled to upon postback?
I want the page when refreshed to remember the position that the user was at on the page, for instance if they are scrolled half way down the page when the page posts back can it return to that position on the page?
I have got the gridview to populate from my own datatable and there are quite a few results in the table. As a result I have a scroll bar on my gridview.
If there is only a few results the gridview works perfectly, however; When I select a row further down in the scroll it selects and highlights but refreshes the view to the top of the gridview.
I have implemented the "slimScroll" in a div. Prior to this implementation, I was using the asp.net inherent scrolling and was able to use the Maintain Scroll PositionOnPostback="true" at the Page level and that worked well; but now, this no longer works.
I am using GeoMap in my website, and GeoMap is little below in Web Page.I am using filters in GeoMap, i.e., when user selects any station and clicks on "button", all the locations related to selection shows in GeoMap. But everytime when I filter and click on button, page loads and scroll upward then again to see the filteration result in Geo Map, I had to scroll down my page.I want that when I filter any station and click on button, page should stick to that GeoMap section. It should not go upward until user scrolls the page.For this I tried using "Update panel" but then GeoMap javascript is not working.
I have some collapse able anhcor link tags on a page that reveal some text when clicked on i.e.: [+] Topic This is all done in javascript client side. I would like to maintain the users scroll position on the page when these links are clicked on. They dont cause a postback as iv mentioned above its client side javascript.
ScrollBar position resets on postback.Is there anyway to maintain position ?I am adding UserControl(s) dynmically to the page, therefore I want to maintian positon (always maintain position at the end)Following is my .aspx file (Just to show where is the asp:panel and User controls)
I have an asp.net listbox with 15 rows and auto postback when the selected item is changed. This works as expected but, when the form is re-loaded, IE scrolls the list so that the last selected item is now the top visible item in the list. This produces a confusing/jumpy effect for the users and makes the listbox more difficult to use than it needs to be.
Is there any way to get the list scroll position to stay as it was before the postback? i.e, if I select an item from the middle of the listbox, the listbox is scrolled to the same point after postback.
I am working on URL Rewriting using RegisterRoutes.

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 have a simple question. I need to keep my position af postback in a scrollbar, where a panel consists of 20 equal user controls. I have attached the code below for the simple form and for the user control.
I have added MaintainScrollPositionOnPostback="true" in the webform, but still the position moves back to the top position of the panel after postback.
I have some problems with maintaining scroll position after postback. First time I experienced the problem was when I (believe) added Combobox control from AJAX control Toolkit and/or UpdatePanel from AJAX Extensions. The problem is when I do the postback on the page the page is loaded at the top and not where I did the postback. Actually, this wouldn't be a problem if it isn't happening on a very large form. I have already tried using MaintainScrollPositionOnPostback="true", but it wasn't helpful at all. I can provide the code if needed, but I don't think it would be of any use because I have comboboxes inside update panels which are rebinded on a button click.
I have a panel inside an update panel. The panel has a scrollbar. When a control inside the panel is clicked, the scrollbar resets, scrolling the panel back to the top. Is there a simple way to preserve the scrolling position of a panel inside and update panel when a postback happens from inside that panel?
I have a gridview control within a panel control. The gridview can contain up to 128 rows. The panel is 300px high and has a vertical scroll bar that allows me to scroll to the row I want to see or edit in my gridview. When I click the "Edit" button on an item within my gridview, the page posts back and returns to panel scrolled all the way back to the top. I have to then scroll back down to get to the item I want to edit in my gridview (which has correctly been placed in edit mode). How can I make the panel return to its postion (or stay in its postion) after a postback without me having to manually scroll back down?
I have to use progress bar when page postback. in my application report section is there. it's taking some time to generate the report. so i want to show some progress bar.
When page load progress bar should show. and when page load finish the progress bar should hide.
I googled many thing mostly they are using thread.sleep method but i don't want that.
The progress bar should fully depend on page loads.
i am using asp.net 4.0 iis 7.5 microsoft visual studio 2010
what i want is keep whole page (browser) scroll position (not a div or panel) when asynchronous postback happened (update panel) how can i do this actually i had a function which can keep div scroll bar position after postback like this
<script type="text/javascript"> var xPos, yPos; var prm = Sys.WebForms.PageRequestManager.getInstance(); prm.add_beginRequest(BeginRequestHandler); prm.add_endRequest(EndRequestHandler); function BeginRequestHandler(sender, args) { xPos = document.getElementById('Main').scrollLeft; yPos = document.getElementById('Main').scrollTop; } function EndRequestHandler(sender, args) { document.getElementById('Main').scrollLeft = xPos; document.getElementById('Main').scrollTop = yPos; } </script>
