An approach to saving data for the user, is the ViewState.

The ViewState allows ASP.NET to repopulate form fields on each postback to the server, making sure that a form is not automatically cleared when the user hits the submit button.

Coding as

in page load event

 if(ViewState["NameOfUser"] != null)
Label.Text = ViewState["User"].ToString();
Label.Text = "Not set yet...";

in submit button click event

ViewState["User"] = NameField.Text;
Label.Text = NameField.Text;

Thanks & Regards,

View state is a repository in an ASP.NET page that can store values that have to be retained during postback. The page framework uses view state to persist control settings between postbacks.

if you have set EnableViewState = false at Page level then it doesn't matter whether EnalbleViewState = true for any control. It will not maintain the ViewState for the controls which resides on Page.

If you have set EnableViewState = true at Page level and for any controls, if you have set EnableViewState = true then for that controls only ViewState will be maintained. For other controls it will not maintain.
