What ASP.NET page lifecycle event can I write code in to determine the size of the viewstate that being sent out? Also, is it possible to determine the size without parsing through the rendered HTML (like a property on the page object) or is parsing the only way?
What I'd like to do is log the sizes, specifically if they cross a certain threshold.

View 4 RepliesI 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 am using TabContainer with some controls on each tab (asp: labels, text boxes). When redirecting to the page that contains the TabContainer, the tabs and their content loads as expected, but when there is a postback, and the page refreshes, the TabContainer UI changes - the font size of the labels gets bigger, the text boxes become bigger and their location changes a bit (not aligned as before), and the tab header is partially hidden. I am using IE7.
I dont know if this is relevant but in some of the text boxes i use edit mask extender as well for date. Also, I have used a table inside the TabContainer for layouting the controls.
Here's the scenario:I have an asp.net webpage which displays dynamic data in a gridview.I'm using a master page to display the header and footer of the page, and this gridview is being displayed inside a div in the contentplaceholder.
The Problem:What I want is that the size of the page that is displayed remains constant for a user and must be equal to the size of their browser's available display area and the content being visible by scrolling the div.Sort of like the header and footer remain at the same position and the content inside it is scrollable.
Do you have any idea about the problem causes change the size of my nested aspx pages which are included in master page... When I click on my menu items, it navigates to new aspx pages which is in the content-placeholder .but new pages are getting smaller so my page contents, images, tables, text are moving. And my internet explorer is shutting down.
View 2 RepliesI have a form, with an update panel and the EnablePartialRendering set to true on the page. Here's my problem, the page size with every AsyncPostBack gets larger, even if my code makes no changes to the markup. It also, never stops... it just keeps growing about 3-4K with every AsyncPostBack. If EnablePartialRendering is set to false, full postbacks do not cause the page size to grow like that. It's like it's sending resources and then never getting rid of them out of the page even though they're not being used because an updated copy has come down.
1.) Is it supposed to work like that?
2.) If it's not, what can I do to not have 4K added to the page size everytime an AsyncPostBack occurs (not again, full PostBacks do not have that same behavior).
3.) This behavior happens whether I compress the ViewState or not (I am using ViewState compression). However, the ViewState size is NOT growing... it's the size of the content in the page that is (I'm monitoring the ViewState size/the Page Size closely).
So we're having this problem. A user goes to upload a file, and if it's above 10MB, it just kind of times out the page, and clears, and no good error is thrown to describe what happened. Ideally, we would like to examine the file size when the user chooses the file they want to upload but I don't know if this is even possible. Our framework is built with ASP.NET, VB.NET, and Javascript (and ExtJS 3.0), and it runs in IE.
View 6 RepliesI have a clarification on Viewstate. I have used the Viewstate machanisum to save the data in particular page. I have to get my viewstate data from one page to another page.

View 3 RepliesI'm using Forms Authentication. Is there a way to determine whether a page (or request) required authentication or not?

I use a separate project for my data layer and call one class within it clsData.cs. I'd like to know which page from the Presentation Layer (in another project within the solution) has referenced it from the clsData side, if that's possible.

ID="hyper1"

NavigateUrl='<%#string.Format("~/PLayer.aspx?ID={0}&Type={1}",Eval("arrange_by_id"),Eval("value"))%>'><%# Eval("value")%></asp:HyperLink>
I've implemented this string format in my NavigateUrl to pass a dynamic querystring depending on the clicked item!
but you see the first part in the string format where it says "~/PLayer.aspx" i want the user control to automatically change this part according to where it's placed!
I have a MasterPage, several content pages - each of the content pages have a UserControl.
In the MasterPage, I'm setting the Page.Title programmatically based on Page_Init "Request.UserAgent.Contains....", so that the content pages end up with different page titles based on this.
Each content page has its Title set to blank (Title=" "), but when the page renders, the pragmatically generated page title shows up in the browser tab.
In the UserControl code behind, I need to access the content page's (parent page) Page.Title value, and base on this, display some text:
If(Page.Title == "something")
{
Lable.Text = "something";
}
else if (Page.Title == "somethingElse")
{
lable.Text = "somethingElse";
}
However, my label remains blank when using this code. What is the way I need to determine the current Page.Title to what the MasterPage has set it as?
I'm looking to alter the way my asp .net webpage is output to the browser depending on the css media type being used. Although the css is generally taking care of the differences in appearance between screen and print mode I would also like to make some minor adjustments to the markup when print mode is required. I would simply be dropping a floated section down below its sibling rather than as a 2 col approach which is to used during screen layout in the browser.
View 3 RepliesSo, I have web apps with web.configs like so:
<authorization>
<deny users="?"/>
</authorization>
<location path="SomeUnsecuredPage.aspx">
<system.web>
<authorization>
<allow users="*"/>
</authorization>
</system.web>
</location>
In other words, most pages require authentication and authorization, but some don't.
Then I have an IHttpModule that will be used by all the different applications. All I want to do is check if the current request is "secured" at all. If the page doesn't require authorization I don't want my IHttpModule to do anything at all. I am using FormsAuthentication and I assume that FormsAuthentication already has all of this information cached somewhere, doesn't it? Also, since this check will be running constantly so it has to be very quick.
I am currently subscribing to the HttpApplication.AuthorizeRequest, but surprisingly this event fires even for resources that allow anonymous access.
I am developing a a web application of a general store where the operator has to enter the things what customer has purchased. Like daily usage item,or anything. So I have form in which I first ask how much item u wannt to register...(if he has 20-30 number of items then operator will enter 20-30 then in gridview 20-30 item are opened. With bind dropdownbox containing name of item ,then textboxs containing mrp, value, stock avail of that item. Here is the link for demo. [URL]. Problem is suppose the operator enter the value above 20, then viewstate size id about 1.50Mb that's too heavy.

Here is .cs code
