In HTML, there's a DropDownList[/code] wo Sie verschiedene Lebensmittelnamen auswählen können, und [url=viewtopic.php?t=14917]ich möchte[/url] den ausgewählten Namen verwenden, um das Whole Food -Objekt zu erhalten, aber nicht auf ausgewählten Lebensmittelnamen zugreifen kann.
[code]Request.Form["selectedFood"][/code] gibt null hier zurück, warum?
