Ich habe eine Ausnahme, wenn ich die Anwendungsseite (/_layouts/collages/uploadcollage.aspx) im Dialogfeld mit dem Inline -Code ausführte.
Code für das Ausführen von Dialogfeld auf default.aspx Seite:
<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>

Oben Code funktioniert nicht, wenn es im SharePoint -Dialog ausgeführt wird. Es funktioniert, wenn es ohne Dialoge ausgeführt wird. (auf url: /_layouts/collages/uploadcollage.aspx).
Jede Hilfe, um es mit dem Dialog zu arbeiten, wäre sehr geschätzt. Was könnte die Quelle des Problems sein?
Lösung
Fragen Sie anwsert.
Ich hatte einen Fehler in meinem C# Code gemacht:
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;
}
Es sollte sein:
private int GetFolderID(SPFolderCollection folders, string folder)
{
for (int i = 0; i < folders.Count; i++)
{
if (folders[i].Name == folder)
{
return i;
}
}
return 999;
}
Nach den Korrekturen sollte es perfekt funktionieren ...
