פתרתי את הבעיה של האירוע שלא התעורר! אבל יש לי בעיה אחרת: ה-DDL השני משנה תוצאות רק כאשר זה דרך האירוע של PageLoad, ולא משתנה דרך האירוע של
SelectedIndexChange
(למרות שהוא מתעורר).

XmlDocument doc = new XmlDocument();
protected void Page_Load(object sender, EventArgs e)
{
string xmlPath = HttpContext.Current.Server.MapPath(@"App_Data/Artists.xml");
if (!IsPostBack)
{
doc.Load(xmlPath);
XmlNodeList list = doc.GetElementsByTagName("Artist");
foreach (XmlNode node in list)
{
string artist = node.SelectSingleNode("@name").InnerText;
Art_nameDDL.Items.Add(artist);
}
LoadAlbums();
}
}
protected void Art_nameDDL_SelectedIndexChanged(object sender, EventArgs e)
{
LoadAlbums();
}
}
