Why won't my ListView SelectedItemTemplate show when selected?

I have a databound ListView in asp.Net. I have both ItemTemplate and SelectedItemTemplate used in the aspx page.

In the .cs page I have this. I have verified by stepping through the code that the if statement evaluates to true only when it is supposed to, and开发者_如何学Go that the selected index is set. However the HTML output is as if all items use the ItemTemplate.

    int indexCounter = 0;
    protected void lvProducts_ItemDataBound(object sender, ListViewItemEventArgs e)
    {
        if (e.Item.ItemType == ListViewItemType.DataItem)
        {
            if (((DataRowView)e.Item.DataItem)["ID"].ToString() == Request.QueryString["id"])
            {
                lvProducts.SelectedIndex = indexCounter;
            }
            indexCounter++;
        }
    }

Is there a better way to do this?

"Setting the SelectedIndex anywhere after DataBinding works, you just don't get the SelectedItemTemplate. For that you have either rebind the data; or reinstantiate the SelectedItemTemplate on the ListViewItem. be sure to clear the ListViewItem.Controls collection first!"
