Viewstate why

An example showing how a transient variable is declared: transient String name;. Each form on your page will have its own copy of view state. This will make sure only a single copy of the view state is associated with that VF page instead of two copies. Use Custom Setting: Use custom setting to store large quantities of read-only data instead of custom objects. To ensure that this occurs, you should set the Page. This issue - and many more like it - can be found using our web vulnerability scanner.

Burp Suite Documentation Take a look at our Documentation section for full details about every Burp Suite tool, function and configuration option. Background A web application is stateless. That means that a new instance of a page is created every time when we make a request to the server to get the page and after the round trip our page has been lost immediately. It only happens because of one server, all the controls of the Web Page is created and after the round trip the server destroys all the instances.

So to retain the values of the controls we use state management techniques. Now I am showing you an example of what the problem is when we don't use view state. Step 1 Open Visual Studio Step 3 Now click on Solution Explorer.

Step 5 After adding the WebForm6. Now the 1 was being displayed in the textbox on my browser, and I clicked the button again, 1 is sent to the server again.

As you can see, I don't need to use Viewstate to "remember" values in previous request, I know textbox in asp. Note that you're asking about ASP. NET WebForms, which is now effectively deprecated. It's an abstraction layer in ASP. NET which was meant to make designing stateful data entry web-pages "web forms" easy by mimicking how VB6 and WinForms works with "server-side events" and "controls" , however it is a very leaky abstraction which falls apart whenever you need precise control of the web-application which is why WebForms is not popular today and why ASP.

NET 5. NET for it to be rendered again. It works similarly to a HTTP cookie that contains a security token. ViewState is not compatible with cookies because it's specific to a single page, not a HTTP session, and it can often reach sizes in the megabytes which is too big for a cookie anyway. I feel WebForms was an interesting experiment for the web - but it added a lot of complexity which was arguably unnecessary, and WebForms applications were inherently non-RESTful, which broke many assumptions about the web that we can now take for granted - for example, it made it almost impossible to automate web-applications through simple requests e.
