View 5 RepliesI have found many articles claiming to show you how to set the scroll position of a ListBox, but what they really end up showing you is how to set the SelectedIndex of a ListBox.
Here is what I need: a databound ListBox that's usually going to have around 25 items in it. When the page loads, ALL of the items in the ListBox are selected, and the ListBox is scrolled all the way to the bottom.
I've got the "All items Selected" requirement already, but I can't figure out how to get the "Scroll to the bottom" done.
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 using .Net 3.5 but no AJAX.
i have a update panel and when a link button is fired i need to set the scroll position to the top. i need this to happen in the code behind, i have tried the following but it wont work.
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "srcoll_0", "window.scrollTo(0, 0);", true);
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.
View 1 RepliesI have a gridview which is placed inside div tag to make the grid view to look like having scrollbars
<div id="divgrd" style="overflow: scroll"; width: 350px; height: 150px>
My grid is placed here.
</div>
Now it displays nice view of the grid with scroll bars. I am changing the color of the row selected from the grid. Only problem is if the grid has around 50 rows and I select the 50th row then the scroll bar moves to the top of the grid. I want to stop it and maintain the scroll position. I cannot change the height of the div tag as the grid may be very large if the rows inside is increased.
I have a panel, inside a panel there are some checkbox and radiobuttonlist. This panel is place inside an UpdatePanel ajax.
When I click on a checkbox, it will raise autopostback with ajax supported, then the scrollbar of the panel always move back to the first position. It does not keep the current scrolling position.
How could I remain the scrollbar position?
I already have tried to add:
this.Page.SetFocus("PanelTrips");
this.MaintainScrollPositionOnPostBack = true;
how can I get back to the same position of a page on postback. It always seems to get to the top of the page
I've tried using ' maintainScrollPositionOnPostBack = "true" ' but its not working.
i used the dropdown list in user control.when i select the dropdownlist that scroll bar went to top.how can i maintain the scroll bar position in that situation?
View 3 RepliesI'm using MaintainScrollPositionOnPostback=true property but this doesn't seem to work with chrome. (works on IE),
Is there any other way to maintain scrool position without using this property?
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.

View 6 RepliesI have taken a div inside the UserContol.
this usercontrol is placed in a page having master page.
In div i have checkboxlist control .
I want to preserver scroll position of while postback.
I have also used UpdatePanel in which i have placed this user control.
I have also triedMaintainScrollPositionOnPostback="true"
but does not work.
My page structure is this:
Masterpage > contentplacehoder (child Page) > UpdatePanel > User control > div > asp:CheckboxList
I want to maintain the scroll position of a page. So I try to get the page cordinates and set the position on the page load (actually I've a postback in my page) using JS as follows. What I've done is on a client click on an image get the page cordinates and keep in a hidden field.
[Code]....
GetScollerPosition function invoke in an image click event. But it's not work as I expected, the SetScrollPostion always find the value of hidden fields as zero.
I have this working in several pages in my site but in one page it wont work!
this is the hierarchyof the page.
I have a treeview in a div,in an asp:panel, in an updatepanel in a user control. the panel is shown/hidden using the ajax modalpopupextender.
this user control is placed in a content page (using a master page).
Now that you got the above, I'll let you know what ive tried already.
I tried doing this:(which works perfectly when the treeview is placed simply in an aspx page)

tried using also :

Basically i kept playing around with it trying different ways but seems like the selected node is just not visible even though i call this JS function after i have selected the Node in code behind.

I am trying to use an anchor tag to automatically scroll down to "position1" when the page loads.
I have created this name tag in the .aspx page and then trying to redirect to that tag in the page_load event but this results in that the page doesn´t load at all and cant be seen in the browser:
I have a multiview control on a page with multiple child view controls. As the ActiveViewIndex is changed when I nagivate between views, I'd like to reposition the scroll position of the browser. For instance, when toggling between a very long page with a huge gridview (page 1) and a smaller page that follows (page 2), I'd like my scroll position to start back at the top of the page when I navigate to the smaller page. Currently, if I scroll down on Page 1 and select an item that navigates me forward to page 2, the scroll position is maintained and I start too far down the page when Page 2 displays. I have programatically set MaintainScrollPosition to false on Page_Load so this should not be a factor.

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.Â

View 2 RepliesI have a .Net Web page that refreshes every few minutes, and all of this works fine. However, a user has made a request for some enhancements. There are two requests, which I am little unsure how to do
1) On my page are scrollable panels, what the user would like is for the position of the scrollbars to maintain their scrollable position during postbacks, because the scrollbars return to the top of panel during each post back. How do I keep the scrollable position of the panels - I have only 3 panels to content with
2) Inside each panel, are dynamically added controls, and these controls have an image button with some javascript which hides or shows a div tag. What the user wants is to maintain the show or hide of a div tag on each of these dynamically added controls during post back. How do I do this?
I am building an application using masterpages, one of the pages contains dynamic gridviews with textboxes using templates. The textboxes have the autopostback enables to allow the calculation of the numeric values entered in each row.
The grid has 3 cols (3rd col has the total of the first and sec cols) the problem is that when i change the textbox (therefore a postback is created) the page scrolls up.
I tried the Page.MaintainScrollPositionOnPostBack = True but it does not work. Can i use any other method to solve this poblem.?
I tried out the solution posted for [URL]
Is there any way to maintain scroll position if I need to re-direct to same page?
