如何从转发器的FooterTemplate获取ddlChangeUser控件。

这不行，因为它不在ItmeTemplate中。

 DropDownList ddlChangeUser = siteMapAsBulletedList.Items[0].FindControl("ddlChangeUser") as DropDownList;

Answer 1

您需要使用ItemDataBound事件并在其中检查Footer。

siteMapAsBulletedList.ItemDataBound += new RepeaterItemEventHandler(siteMapAsBulletedList_ItemDataBound);

...

void siteMapAsBulletedList_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
    if (e.Item.ItemType == ListItemType.Footer)
    {
        DropDownList ddlChangeUser = (DropDownList)e.Item.FindControl("ddlChangeUser");
        if (ddlChangeUser != null) {
                   ...
        }
    }
}
