How can i get ddlChangeUser control from FooterTemplate of repeater.

This is not ok, becouse it is not in ItmeTemplate.

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

You need to use the ItemDataBound event and in there check for 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) {
                   ...
        }
    }
}
