Sharepoint應用程序頁面僅在對話框中拋出異常

當我在對話框中運行應用程序頁面（/_layouts/Collages/UploadCollage.aspx）時嵌入代碼的內嵌代碼時出現異常。Sharepoint應用程序頁面僅在對話框中拋出異常

代碼Default.aspx頁面上運行對話框：

<script type="text/javascript"> 

//Handle the DialogCallback callback 
function DialogCallback(dialogResult, returnValue) 
{ 
    // Occurs when upload succeeds 
    if(SP.UI.DialogResult.OK == dialogResult) 
    { 
     this.statusId = SP.UI.Status.addStatus("Publishing complete:", "Published content available on Collages Library", true); 

     SP.UI.Status.setStatusPriColor(this.statusId, "green"); 
    } 
    // Occurs when upload throw exception 
    if(SP.UI.DialogResult.cancel == dialogResult) 
    {  
     this.statusId = SP.UI.Status.addStatus("Publishing failure", "An error occurs. Try again", true); 
     SP.UI.Status.setStatusPriColor(this.statusId, "red"); 
    } 
}

上面的代碼不工作時，正在運行Sharepoint對話框。它在沒有對話框的情況下運行。（在Url上：/_layouts/Collages/UploadCollage.aspx）。

任何幫助使它與對話框工作將非常感激。什麼可能是問題的根源？

你可以張貼例外呢？ – 2011-05-02 12:44:33

問題無法解決。

我曾在我的C＃代碼犯的錯誤：

private int GetFolderID(SPFolderCollection folders, string folder) 
    { 
     for (int i = 0; i < folders.Count - 1; i++) 
     { 
      if (folders[i].Item.DisplayName == folder) 
      { 
       return i; 
      } 
     } 
     return 999; 
    }

它應該是：

private int GetFolderID(SPFolderCollection folders, string folder) 
    { 
     for (int i = 0; i < folders.Count; i++) 
     { 
      if (folders[i].Name == folder) 
      { 
       return i; 
      } 
     } 
     return 999; 
    }

後更正，應該很好地工作......
