Viewstate stored in which format

If you fill a form and send it to server for processing but after round trips [when page return from server] then every data would be lost.

To overcome this, ViewState technique has introduced. View State uses HiddenField to store page information or control value in key-value format and value stored in baseencoded strings encrypted format. View State can enable or disable the View State on control level, page level. By default View State is enabled for page.

You can enable or disable ViewSate on page level in page directive. You can change EnableViewState value to true or false. I hope this post will help you.

When the page is first created all controls are serialized to the ViewState, which is rendered as a hidden form field named ViewState.

This hidden field corresponds to the server side object known as the ViewState. ViewState for a page is stored as key-value pairs using the System.

StateBag object. When a post back occurs, the page de-serializes the ViewState and recreates all controls. The ViewState for the controls in a page is stored as Base64 encoded strings in name - value pairs. The following is the content of the ViewState hidden field as generated for a page in my system. By default, all pages have view state enabled. The actual data is stored in a hidden field on the form - take a look at a page's source, and you'll quickly find the field hosting the data.

The data is not encrypted, so it does present security risks; however, it is Base64 encoded, which doesn't make it easily read by the naked eye. Like session state, view state may be disabled on the page level via the EnableViewState attribute of the page directive. Likewise, most individual controls have the same property available.

It may be disabled for the entire site in the web. The size of the hidden field used to maintain view state can become large, so disable it whenever it is not needed. Problems With Viewstate ViewState has lots of advantages and as well as disadvantages, so you need to weigh carefully before making the decision to use it. Is ViewState secure? In this mode, ASP. NET does not wait for a control in the page to request encryption. ViewState is always encrypted. When working with sensitive data, it is a good practice to utilize encryption.

The mode is a property on page, but is set using either a page directive or in the web. What is Autopostback in asp net?

Autopostback is the mechanism by which the page will be posted back to the server automatically based on some events in the web controls. In some of the web controls, the property called auto post back, if set to true, will send the request to the server when an event happens in the control.

What is Enableviewstate in asp net? A server control's view state is the accumulation of all its property values. NET uses an instance of the StateBag class to store the property values. The values are then passed as a variable to a hidden field when subsequent requests are processed. What is difference between ViewState and session in asp net? Storage The Viewstate is stored within the page itself in encrypted text , while the Sessionstate is stored in the server.

Session is used mainly for storing user specific data [ session specific data ]. Viewstate is the type of data that has scope only in the page in which it is used.
