Obviously, first priority is disabling and not using Viewstate as much as possible, but if you have to, is this worthwhile? Also considering that IIS is gzipping everything for you as well. ViewState is smaller however is the trade off of CPU worth it?

Trying to give a client some guidance based on this.
PS: They are using .NET 2.0
I agree that the best way to shorten the ViewState is to disable it on the ASP.Net controls that don't need it. Keeping it small from the beginning is a great habit.I have also heard that it is already compressed (although can be true... there are ways of compressing it even more, has described in this Stack Overflow question).
My question here is not if it should be compressed... is: when should ViewState be compressed?If we have a ViewState of 410 characters it will weight 410 bytes in a page, while a ViewState of 13.843 characters equals 13.5 KB.13.5KB is a considerable weight already. And if I compress a CSS file that height 10KB, I think it is also worthy compressing a ViewState of 13.5KB, even if that means a little extra "thinking" on the server.But is 410 bytes of ViewState worth the extra processing on the server?
I'm wondering how much performance suffers form using an ORM. It only makes sense that straight ADO.net would be faster than an ORM since they are built on top of ADO.net.
I'm not building any high traffic sites or using any incredibly large record sets. I'm seriously considering using LINQ after having to add a number of classes to my DAL and my BAL. The ease and reduction of work from an ORM seems very advantageous. I'm thinking it would far out weigh any performance concerns for me.
How much of a performance hit does using an ORM create? I would think that this would depend on the number of users and size of the record sets but I would like to get an idea of the impact of this. How many hits per day/ size of the record sets would be the threshold?
Do any of you have any complaints about the performance hit from an ORM? Do you prefer the reduction in work over any performance hits?
I have to create a web application that allows you to create specific XML documents. To generate a document, the user must be able to fill out fields that will be the XML content, using dropdown lists, text input fields, calendar controls ... Some fields will be validated. use some default values (text, new GUID, current date ...) add or remove sub nodes. The minimum an maximum number of nodes will be validated. All fields, relations and validations should be configurable by using config files. I have an idea of how to implement this in a homebrew MVP or MVVM pattern way.
Now I wonder if MVC 2 can help me enough to justify the learning curve. (MVC 3 is not an option, as my client still uses VS2008.) In two weeks I should have a working application. It is for internal "power user" use, so it doesn't have to look too fancy, but the main concept and functionality should be waterproof. My background: I have many years of experience with Win Forms developement and basic knowledge of ASP.NET (did some smaller apps with it).
Now here is the weird thing. First i am running it locally on the built in vs2008 web server.I load my control in fine, do a postback from a linkbutton, locally on my machine it all works fine, no issue.However when it goes onto my host, it falls over with the message:
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.Now i also load controls dynamically and use postbacks and things in the admin area of the site...and that works fine, however my front end just keeps failing? See the code behing below:
[Code]....
I have problem getting values from viewstate in GetTopThemes.
<asp:ObjectDataSource
ID="sourceGetTopThemes"
runat="server"
TypeName="DBConnection"
SelectMethod="GetTopThemes"
EnableViewState="true"></asp:ObjectDataSource>
[Code]....
}
[Code]....
when the page is not Posted back, I saved all values in the viewstate.
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 know the difference between ASP.NET webforms and ASP.NET MVC and I've seen quite a few videos explaining that they both run on top of ASP.NET (and I've used both). However, my question is, how would one develop right on top of ASP.NET without webforms or mvc.net?
View 5 RepliesI am converting a webforms app to mvc. I implemented localization in webforms this way: The user selects the language, which BTW can be an rtl language, and the selection goes into the user profile in order for it to persist the next time the user visits the site. I used anonymous profiles. also, I used resource files.The db tables have multiple rows for each language (with a language index field). I also used different style sheets for ltr and rtl languages since I don't use tables on my site (Is there another way instead of using separate style sheets?) What are the best practices for using localization in asp.net mvc ? can I and should I use resource files ? and profiles ? should I map the aspnet tables to linq-to-sql ?
View 1 RepliesIf I use a Server.Transfer command with a true value passed for the "PreserveForm" 2nd param's value:
Default.aspx:
Server.Transfer("WebForm1.aspx", True)..I can access the value of the textbox "TextBox1" control on the first page, Default.aspx, from "WebForm1.aspx" as follows:
lblPassedValue.Text = Request.Form("ctl00$MainContent$TextBox1")
I know that I can control the way that IDs are generated in Visual Studio 2010, but how about controlling the NAME property?
I would like it to read:
lblPassedValue.Text = Request.Form("TextBox1")
I'd also rather use ASP.NET Textbox controls rather than a native HTML textbox.

I want to use "NVelocity" from plain ASPX pages without using any MVC framework. I don't want to use "NVelocity View Engine" thru' asp.net MVC framework. The only example that I got for "NVelocity" is for merging and writing onto console window (http://www.castleproject.org/others/nvelocity/usingit.html)
I am looking out for example on to integrating "NVelocity" into aspx web forms.
I have a mixed project: WebForms with ASP.NET MVC2 and is running OK. I have done this tutorial on separate MVC Project and localization is working fine. However, when I want to apply localization (mentioned above) in my mixed project, it seems to be ignored. It doesn't matter what I set in global.asax file (de-DE, fr-FR, pl-PL) always get en-EN or en-GB. This is really strange. web.config is correct and doesn't force the localization.
View 1 RepliesI am developing a simple application. I have completed.
1 - Using Respositary Pattern
2 - using DataAnnotation for validation.
3 - Selecting, Creating, Updating and Deleting.
My Questions.1 - I have extra BL validation. Should I create Service layer or use that in Partial Class where my DataAnnotation is?
I dont want to use DataAnnotations in one class and other BL validation in another class. Is there a way to combine both or Should I use those separately. Confused here? Any examples to implement BL.
2 - I have lots of Calculations to run once record is reterived and insterted. Where I put these calculations? Should I make extensions and call in controller or Methods in separate file. Any clean approach.
3 - Can I use Repositary Pattern and Service model in ASP.NET webforms with ADO.NET, Entity Framework and Linq to sql?
4 - I don't know id this is stupid question. Can we use ADO.NET with DataAnnotation somehow in Webforms and ado.net with mvc?.
i know ASP.NET and i would like to learn and make a new project in ASP.NET MVC. Is it easy to move from asp.net to asp.net mvc? Will the knowledge i have so far be helpful? Im asking because i will have only few days to learn asp.net mvc and i want to know whether it's possible.
View 4 Repliesavoid using MS AJAX completely while developing ASP.NET Webforms applications and use jQuery/jQuery Tools instead?
I have a completed app running in a QA environment. Everything works fine under most circumstances.If you hit a plain URL (no identifying information in the URL), you see an intro page with a button (generated by an asp LinkButton control) that posts back and directs you to another page. The markup looks the same when it fails and when it doesn't.
When such a URL is followed from, e.g., Word and the default browser is IE, the intro page loads fine, but clicking the button causes an error. When not debugging, this behavior occurs every time. While debugging, the error occurs only ~ 1 in 10 times (closing the browser instance and starting over every time).When the error occurs, the intro page Page_Load fires and IsPostBack is false. Somehow, instead of a post, a get is being issued.
When I run fiddler to try to analyze the actual calls (can't use firebug because it never happens using Firefox), everything works every time.I don't know whether this issue has anything to do with routing, and I've no idea even what to look at next. The strange thing is, when I debug, the intro page doesn't fully load every time. Only about 1 in 3 times does it fully load even if I've just cleared browser cache. When I run it through fiddler, it fully loads and works fine every time.
I have been trying to figure out how to use the Routing features with ASP.net 4.0 WebForms. I added a route to my route collection:
void Application_Start()
{
RegisterRoutes(RouteTable.Routes);
}
void RegisterRoutes(RouteCollection routes)
{
routes.MapPageRoute(
"about-route",
"about/",
"~/About.aspx"
);
}
In my master page I tried to do the following: <asp:HyperLink ID="asdf" runat="server" NavigateUrl='<%= GetRouteUrl("about-route", new {}) %>'>Test</asdf> I got a compiler error: Server tags cannot contain <% ... %> constructs. What is the proper way to create a route URL in a server control in Web Forms? I also need to include it in the following:
<asp:Menu ID="NavigationMenu" runat="server" CssClass="menu" EnableViewState="false" IncludeStyleBlock="false" Orientation="Horizontal">
<Items>
<asp:MenuItem NavigateUrl="ROUTE HERE" Text="Home"/>
<asp:MenuItem NavigateUrl="ROUTE HERE" Text="About"/>
</Items>
</asp:Menu>

I currently work for a company that uses a combination of ASP.NET Webforms and legacy ASP pages for web development. This works fairly well for their current projects but I would like to convince / suggest to them to switch over to ASP.NET MVC since most of their codebase consists of wiring form elements to stored procedure parameters. Just using an ORM is also a possibility but I think it would be a good idea to use this opportunity to switch to an MVC framework.
However, I'm not sure how easy it will be to deploy an ASP.NET MVC app along side ASP.NET and Classic ASP code while the codebase is updated. First, I would like to ask if this is even possible. I've seen threads about running ASP.NET with Classic ASP and ASP.NET MVC with Webforms but not all three in the same application. They currently have Webforms and Classic ASP working together so the pitfalls associated with that are already solved.
Is there any way to use ajax I'm using Jquery for this) with asp.net webforms without having to run through the pages life cycle?
