Sharepoint application Page lancer seule exception dans le dialogue

Question

Je vais avoir exception quand je suis en cours d'exécution d'application Page (/_layouts/Collages/UploadCollage.aspx) sur le dialogue avec le code en ligne intégré en elle.

Code pour dialogue en cours d'exécution à la page Default.aspx:

<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");
     }
} 

//Open the Dialog 
function OpenUploadDialog()
{ 
   SP.UI.Status.removeAllStatus(true);
   var dialogOptions = SP.UI.$create_DialogOptions();
   dialogOptions.width = 600;
   dialogOptions.height = 800;
   dialogOptions.url = "/_layouts/Collages/UploadCollage.aspx";
   dialogOptions.dialogReturnValueCallback = Function.createDelegate(
                    null, DialogCallback);
   SP.UI.ModalDialog.showModalDialog(dialogOptions);
}</script><p>?</p>

code ci-dessus ne fonctionne pas quand il est en cours d'exécution dans le dialogue Sharepoint. Il fonctionne lorsqu'il est en cours d'exécution sans dialogues. (Sur Url: /_layouts/Collages/UploadCollage.aspx).

Toute aide pour makeing le travail avec dialogue serait très appréciée. Quelle pourrait être la source du problème?

Answer 1

Question anwsered.

J'avais fait erreur dans mon code C #:

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;
    }

Il devrait être:

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

Après corrections, il devrait fonctionner parfaitement ...
