SQL Stored Procedure nicht erhalten Parameter von VB übergeben

Question

So habe ich eine Mauer mit meinem Projekt erreicht, an dem ich gearbeitet habe. Ich versuche, ein Suchformular zum Funktionieren zu bringen, indem ich dem Benutzer erlaube, Daten in jedes Formularfeld einzugeben, dann suche nach allen spezifischen Feldern. Dies sollte alle Zeilen zurückgeben, die anwendbar sind.

Was passiert ist, wenn der Benutzer die Suche ausführt, wird der Text aus dem Formularfeld genommen und in VB zur Validierung gebracht und dann in eine gespeicherte Prozedur geschoben. Die gespeicherte Prozedur sieht jedoch nicht die Parameter, die übergeben werden. Ich habe ein paar verschiedene Methoden ausprobiert, um die Daten zu bekommen, aber es passiert einfach nicht. Wenn ich den Code mit einem Unterbrechungspunkt ausführe, kann ich SEHEN, dass der Text gerade in den VB gebracht wird, aber er wird nicht als Parameter übergeben (tatsächlich finde ich im Haltepunktfenster nichts, was sagt mein Parameter wird generiert)

Der Fehler ich erhalte ist:

Prozedur oder Funktion ‚SearchFarmStand‘ erwartet Parameter ‚@Farm_Business_Name‘, die nicht geliefert wurde.

Ich habe versucht, googeln für mehrere Stunden das ohne Erfolg zu beheben

ich viele Änderungen in der Hoffnung gemacht habe, dass ich es Arbeit bekommen konnte, aber ich habe nicht erfolgreich gewesen. Ich habe versucht, den Standardwert für die Parameter auf NULL zu setzen, aber die Parameter werden immer noch nicht abgerufen, obwohl es die Prozedur durchläuft, es gibt nur nichts zurück. Auf der VB-Seite der Dinge habe ich auch viele verschiedene Möglichkeiten versucht, die Parameter mit cmd.Parameter.Add und cmd.Parameter.AddWithValue zu deklarieren. Mein Code zeigt meinen letzten Versuch, den Parameter zu erhalten.

Jede Hilfe wäre genial, wie ich

Die folgenden vollständig bin stecken ist mein Code:

Answer 1

Also habe ich herausgefunden, was passiert ist. Ich hatte eine zusätzliche SQLDataSource, die festgelegt wurde, um die gespeicherte Prozedur zu ziehen, jedoch wurden keine Parameter in der sqldatasource festgelegt. Dies war getrennt von der VB, die ich erstellt hatte, um die Parameter zu erstellen.Was ich getan habe, ist die unnötige sqldatasource entfernt und mein Code funktioniert jetzt perfekt.

Answer 2

<asp:CheckBox ID="VegetablesSearch" Text="Vegetables" runat="server"></asp:CheckBox><br /> 

If VegetablesSearch.Text = "True" 

Woran glauben Sie, dass der Text der CheckBox "True" ist?
