Problem with OnItemDataBound

[Dan]

Have a RadListBox with OnItemDataBound going to this method:

protected void listWho_ItemDataBound(object sender, RadListBoxItemEventArgs e)
        {
            if (!IsPostBack)
            {
                    DataRowView dataSourceRow = e.Item.DataItem as DataRowView;
                    string pkValue = dataSourceRow["pk"].ToString();
                    if (pkValue == "51" || pkValue == "53")
                    {
                        e.Item.Selected = true;
                    }

            }
        }

The problem is that dataSourceRow is null.  Why?

I figured it out.  The code should be:

protected void listWho_ItemDataBound(object sender, RadListBoxItemEventArgs e)
        {
            if (!IsPostBack)
            {
                    string pkValue = e.Item.Value;

                    if (pkValue == "51" || pkValue == "53")
                    {
                        e.Item.Selected = true;
                    }
            }
        }

So, it appears that the documentation here should be revised:
