Rajeesh Menoth · Answer

Hi, ViewState is used to maintain the state of controls during page postback and if we save any control values or anything in viewstate we can access those values throughout the page whenever it required for that Example : protected void Page_Load( object sender, EventArgs e) { if (!IsPostBack) { string str = "Hello World" ; if (ViewState[ "SampleText" ]== null ) { ViewState[ "SampleText" ] = str; } } } protected void btnClick_Click( object sender, EventArgs e) { lblString.Text = ViewState[ "SampleText" ].ToString(); } Reference : http://www.aspdotnet-suresh.com/2012/11/viewstate-in-aspnet-with-example-in-c.html http://www.c-sharpcorner.com/UploadFile/225740/what-is-view-state-and-how-it-works-in-Asp-Net53/ http://asp.net-tutorials.com/state/viewstate/

Hi View State is one of the most important and useful client side state management mechanism. It can store the page value at the time of post back (Sending and Receiving information from Server) of your page. ASP.NET pages provide the ViewState property as a built-in structure for automatically storing values between multiple requests for the same page. Example: If you want to add one variable in View State, Hide Copy Code ViewState["Var"]=Count; For Retrieving information from View State Hide Copy Code string Test=ViewState["TestVal"] plz refer. http://www.codeproject.com/Articles/31344/Beginner-s-Guide-To-View-State http://www.c-sharpcorner.com/UploadFile/225740/what-is-view-state-and-how-it-works-in-Asp-Net53 Life cycle: http://www.tutorialspoint.com/asp.net/asp.net_life_cycle.htm

Kidamarthi View State is the method to preserve the Value of the Page and Controls between round trips. It is a Page-Level State Management technique. View State is turned on by default and normally serializes the data in every control on the page regardless of whether it is actually used during a post-back.
