State Management :: ViewState - Does The Master Page Have Its Viewstate

Apr 30, 2010

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?

C# - Page With ViewState Disabled Still Be Validating A Viewstate Field?

Sep 24, 2010

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.

Capture Errors On A Per-page Level?

Aug 9, 2010

I want to capture errors on a per-page level. I've added the following code to my code behind page:

public void Page_Error(object sender, EventArgs e)
{
Response.Write("Unhandled error on the page.");
}

I have also ensures that AutoEventWireup="true".

I have some gridviews on this webpage that use a SQLDataSource. I'm hoping to use this error message (which will be better when I get it working, response.write is mostly just to test) to cover up those errors with something more user friendly. Yet when I have an error ("Cannot open database" for instance), Page_Error never fires and I get the ugly yellow screen of death instead.

Configuration :: Set HttpRuntime ExecutionTimeout On Page Level?

Mar 30, 2010

We have a function which sends out a bunch of e-mails. The problem is that a HttpException is thrown on the server after a while.

I managed to find out the the solution is to increase the executionTimeout in web.config, but I only want this on one page, not the whole application.

Is there a way to set the executionTimeout configuration only on one page?

C# - Disabling Page Level Cache/Dangers?

Mar 9, 2011

Basically, the reason I am disabling the cache is because I have DevExpress ASPxGridViews, which work great for filtering, sorting, etc. but the client is working with large amounts of data and has requested that we save the filter/sort between page navigations.

The way this is done is via an event that occurs, ClientLayout. The problem is, when the user navigates to a different page, and then clicks the browsers Back button, the events do not fire, and the unfiltered grid is displayed, presumably because this is what was cached. (However a link back to the grid's page causes the page to load properly, and the events to fire.)

The only way I have been able to solve the problem is to disable caching as pointed out in this link:
http://forums.asp.net/p/1304752/2563283.aspx

Obviously, just because I CAN do it, doesn't mean its a good idea. I understand it might affect performance a bit, but can anyone tell me of any other problems that might occur? Maybe AJAX problems or controls giving out unexpected behaviour?

Maintain Current Page When Updating Top Level Parameter In MVC?

Nov 23, 2010

After working on a page for quite some time, the customer now decided that they wan't to be able to change a top level setting but still maintain the current page they're in.

Say for example:

User goes to default page, clicks on the UserSettings which is loading a partial view. In that partial there is multiple links like Address, Password, Other. Click Address (any of these) and it will load a partial within the partial. This will of course maintain the link "MyProject/User/1" in the URL bar.

When the User now change in the drop down in the top level, from User 1 to User 2 this will update the URL to be "MyProject/User/2" and will load the matching action with that. However, I wan't to be able maintain the user selection from before (MyProject/User/2, click UserSettings, click Address).

If I knew this from the beginning I would have done it completely different, but this now a request from the customer after the project is done so I'm look into if there is any "easy" way

[code]....

I can also add that I've tried to do something like this to figure out what exact page I'm on:

var foo = window.location.pathname;

but that only gives me what ever I already have in the URL bar, and not any information about what partial that potentially would be loaded. Is there any way to see what partials is dynamically loaded at the moment?

Basically loading View -> Partial View -> Partial View. Changing the setting for the View but still want to maintain View -> Partial View -> Partial View, but now for the new User

C# - Session At The Page Level Blocks The Pagemethod Calls?

Feb 24, 2011

The Situation: When there multiple PageMethod calls in a single page, each of the method call holds a lock on the Session object thus blocking. The PageMethod calls can be made asynchronous only with @Page directive is turned to False|ReadOnly

Findings: When the Page directive is default (read/write) but the session is not used anywhere on the page, the calls are not blocked. Any read or write in to the session at the page level blocks the pagemethod calls.

The Problem: Making EnableSessionState=ReadOnly at the @Page directive is very restrictive and don't want to take that route. Can the pagemethod calls not block? and still access the session? (may be not write but just read)

Determine Size Of Page's Viewstate Before Serving Page?

Oct 28, 2010

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.
