此代码应をrk，在本地测试：

{ 
    if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) 
    { 
     Panel panel1 = e.Item.FindControl("Panel1") as Panel; //assume your panel name is Panel1 
     if (panel1 != null) 
     { 
      Label LblHead = panel1.FindControl("LblHead") as Label; 
      if (LblHead != null)

       string LanguageID = Globals.GetSuitableLanguage(Page); 
       if (LanguageID == "ar") 
       { 
        LblHead.Attributes.Add("CssClass", "hed_logo2");

添加下列检查，

if (e.Item.ItemType == ListItemType.Item || 
       e.Item.ItemType == ListItemType.AlternatingItem) 
{ 
    // your code here 
}
