Question

As I have problems loosing indexes after postbacks, is it beter to remember indexes or values in sessions?

Thanks.

Answer 1

I’d say store them in sessions, HOWEVER, do you make any selection stuff in the page load event, if so, have you checked so that it won’t redo that population after a postback??

This could mess things up, this would set the time on every postback:

    protected void Page_Load(object sender, EventArgs e)
    {
            Label1.Text = DateTime.Now.ToString();
    }

This would however have your stuff remain intact in the viewstate and the time would only update if the page is loaded without a postback:

    protected void Page_Load(object sender, EventArgs e)
    {

        if (Page.IsPostBack != true)
        {
            Label1.Text = DateTime.Now.ToString();
        }
    }
