Question

I need a field to store some information after one asp button click for another asp button’s click.

I saw that it wasn’t working so I wrote the following simple page codebehind (thinking that perhaps some of my code was causing it) but here I can see that the field really does get re-initialized.

I suppose that every button click reloads the page. Is this true? And if so – how can this be overcome without a static variable (-because what if more than one person is accessing the same page at once…)?

public partial class _Default : System.Web.UI.Page
{
    string s = "a";

    protected void Page_Load(object sender, EventArgs e)
    {

    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        s = "b";
    }

    protected void Button2_Click(object sender, EventArgs e)
    {
        here.InnerText = s;// "here" is an id.
        //returns "a" despite Button1 having been clicked before.
    }
}

add in your code (EnableViewState)
