Moving ViewState To Bottom Of Page
Mar 4, 2010
What are the latest and greatest ways to move ViewState to bottom of the page Can this be done in a IHttpHandler that can be specified in the web.config to intercept requests to "*.aspx"?
<httpHandlers>
<add verb="*" path="*.aspx" type="MyApp.OptimizedPageHandler" />
<httpHandlers>
Other options is that this could be done in a IHttpModule, but that is not as performant, as it will intercept all requests. Also it could be done in an a class deriving from the Page or MasterPage-class, but this is not as modular.Are there any performance penalties to this?

I have been getting this error a lot lately with some of my users, and I had a couple of concerns with view state and I have read so many articles but I am still lost..
1. I use masterpage on all the pages and I need viewstate for some of the pages but..
There is a page where a user will fill out the information and then submit this data to a cgi server, and it is where I get most of the Client Disconnected errors, what would happen if I disable viewstate when they click on that button?
Now when a user browses from one page to another, does the view state from the previous page get deleted? If not how would I delete it?
Does the master page have its own viewstate? Would I be able to make sure none of items on my master page are using the viewstate?

I have a shopping cart page (Cart.aspx) that has a button that will (sometimes) post to a third party payment gateway, if payment is necessary. The payment gateway will process the payment and then do a silent post to my website (Order.aspx) so I can update the order status.
Order.aspx always throws an invalid viewstate error, even though viewstate is disabled on the page.
What's happening is that Cart.aspx (which has viewstate enabled) posts to the payment gateway, and the gateway will post it back as part of the silent post. Even though Order.aspx has viewstate disabled and validation disabled, it still tries to validate the __viewstate field it's being given.
I know setting EnableViewState=false will disable the rendering of the __viewstate field, but if another page provides the field, shouldn't it still skip validation? I tried calling ViewState.Clear() on the Page_Init event of Order.aspx, but ViewState is apparently empty. how to get around this? I don't want to disable ViewState on Cart.aspx (in some cases it may be necessary), but I can't figure out how to clear it on Order.aspx.

I have a page that I am adding user controls to the bottom of the controls each postback. The User Control has a textbox in it and the focus needs to be on this newly created control textbox each time. It all works almost perfectly however when there are too many controls to fit on the page, because I set the focus to the textbox the bottom of the page is set to the textbox that has focus not the very bottom of the page. I have a submit button below this which ends up below the page limit. How can I set focus to a textbox but still scroll to the every bottom of the page to show the submit button.

I have a grid view where the user can change pages at either the top or the bottom of the grid view. I want the view to go back to the top whenever a user changes the page, whether they are changing from the top or the bottom. I've tried using anchors and javascript to achieve this but it does not work. The javascript is executed and the user is taken to the top of the gridview, this can be seen by placing an alert after the javascript to change the view. But the last thing that happens on the page change is that the window is returned to it's previous position (the bottom of the page). Is there any way of doing this?

I got a problem with an Ajax form in MVC2 (VS 2010).Well I got an Index.aspx that has a Ajax.BeginForm, with a textbox and a input button (Button 1). The HttpPost of this simple form, will be handled by an action of my controller. This action will render a PartialView.The PartialView has a table that I fill with a ViewModel. Also it has another Ajax.BeginForm and another input button (Button 2). This new Ajax.BeginForm is handled by an action that has to do something with the data posted.
Here's the thing: I click the Button 1, fill the table and everything is going well, but after that when I click everywhere in the page, the Button 2 change it's position to the bottom of the page and get the focus ... I don't know why ...

I have a requirement to position a div on the bottom of the last page when printing. Consider I have a page set up as follows.
[div id=Header]
[/div]
[div id=Lines]
x Number of lines that could potentially span 1 or more pages
[/div]
[div id=Footer style="position: absolute; bottom: 20px; left: 4px; right: 4px;"]
[/div]
No this code is fine if there are a few lines on the page, but if there are more than just a few the footer then overlaps some of the lines. Is it possible in CSS to fix the footer to the bottom of the page, but to attach to the bottom of the second page if the lines fill the first page. I think its the position absolute that is causing the problem. Has anyone else done this that has an alternative?

I have a wierd issue with a ModalPopupExtender. I am using a GridView and a DetailsView Control inside a ModalPopupExtender to show the details. After I Hide the ModalPopupExtender it renders at the bottom of the page. The popup works fine, just when i close it it moves to the bottom. If i click on another item and close it, it just builds at the bottom of the page. If i click Save it closes and falls to the bottom of the page and my Update sql statement contains all the values of the below popups. Wierd huh!
I have tried both using the OKControlID and creating an event handler to do a ModalPopupExtender.Hide(); neither works. I have used the ModalPopupExtender a number of times and have never seen this happen.

We have designed RDLC having tables and binding dynamic data to the tables, so that we can export it to PDF.
While binding the data to the table, if the cell content which we are binding to the table row is large and doesn't have enough space to fit in the page, then the table row is moved to next page and because of this we are able to see blank space at the bottom of the previous page.
For example, if there is a table in a page with 3 rows, if the 3rd row is huge and cannot fit into the the same page with other rows; the 3rd row is moved to the 2nd page. There is huge space after the first 2 rows in the first page because of this. ive tried resizing the details section but it didn work.

I have an issue that may be tied to layering of ajax controls. On my page I have a Modal Popup that displays and has multiple input fields on it.One of which is a dropdown list that shows one of two sections OnSelectedIndexChanged. One section has a button that calls another Modal Popup with inputs.
When I cancel/close the 2nd Modal Popup and change the value of the dropdown list the Popup's panel displays at the bottom of the page.I have tired hiding the panel, calling the mpe.hide(); etc but cannot get this panel to stop displaying.
