FormView.DataItem is null on postback
===

I am using a LinqDataSource and a FormView with paging enabled on an ASP.NET page. I am trying to access the FormView's `DataItem` property on `PageLoad` and I have no trouble on the first page load, but as soon as I use the Next/Prev page button (causing a postback) on the FormView the `DataItem` property is null, even if there a record showing in the FormView. Any ideas why it works fine on the first page load but not on a postback?

If you're curious what my `PageLoad` event looks like, here it is:

    protected void Page_Load(object sender, EventArgs e)
    {
    	Label lbl = (Label)fvData.FindControl("AREALabel");
    	if (fvData.DataItem != null && lbl != null)
    	{
    		INSTRUMENT_LOOP_DESCRIPTION record = (INSTRUMENT_LOOP_DESCRIPTION)fvData.DataItem;
    		var area = db.AREAs.SingleOrDefault(q => q.AREA1 == record.AREA);
    		if (area != null)
    			lbl.Text = area.AREA_NAME;
    	}
    }
