Public Overridable ReadOnly Property HelpVerb As WebPartVerb

Waarde van eigenschap

Een WebPartVerb functie waarmee gebruikers toegang kunnen krijgen tot Help-inhoud op de WebPart besturingselementen in een zone.

Kenmerken

PersistenceModeAttribute

Voorbeelden

In het volgende codevoorbeeld ziet u het gebruik van de HelpVerb eigenschap op een WebPartZone besturingselement.

Naast de volgende code hebt u een aangepast besturingselement WebPart nodig om het codevoorbeeld te laten werken. U kunt uw eigen beheer gebruiken of de code gebruiken voor het aangepaste TextDisplayWebPart besturingselement in het gedeelte Voorbeeld van het WebPart klassenoverzicht.

Dit codevoorbeeld bevat een gebruikersbeheer waarmee u weergavemodi op een webpagina kunt wijzigen. Zie Walkthrough: Weergavemodi wijzigen op een pagina met webonderdelen voor meer informatie over weergavemodi en de broncode in dit besturingselement.

Dit codevoorbeeld bevat ook een HTML-pagina die Help-inhoud voor het TextDisplayWebPart besturingselement kan bevatten. Als u dit voorbeeld wilt laten werken, moet u de volgende code opslaan in een bestand met de naam Textwebparthelp.htm en deze in dezelfde map van uw site plaatsen als de .aspx pagina waarop het TextDisplayWebPart besturingselement wordt gehost.

<html>
<head runat="server">
    <title>Text Content WebPart Help</title>

Houd er ook rekening mee dat de HelpVerb eigenschap declaratief wordt gebruikt voor het <asp:WebPartZone> element om de tekst voor het werkwoord in te stellen, zoals wordt weergegeven in het volgende codevoorbeeld.

<asp:WebPartZone ID="WebPartZone1" Runat="server">
  <CloseVerb Text="Close WebPart" />
  <HelpVerb Text="View Help" />
  <ExportVerb Text="Export WebPart Definition" />
  <DeleteVerb Text ="Delete WebPart" />
  <MinimizeVerb Description="Minimize the control" />
  <RestoreVerb Description="Restore the control" />
  <ZoneTemplate>
  </ZoneTemplate>  
</asp:WebPartZone>

<asp:WebPartZone ID="WebPartZone1" Runat="server">
  <CloseVerb Text="Close WebPart" />
  <HelpVerb Text="View Help" />
  <ExportVerb Text="Export WebPart Definition" />
  <DeleteVerb Text ="Delete WebPart" />
  <MinimizeVerb Description="Minimize the control" />
  <RestoreVerb Description="Restore the control" />
  <ZoneTemplate>
  </ZoneTemplate>  
</asp:WebPartZone>

Let ten slotte op in het volgende codevoorbeeld dat de HelpUrl eigenschap is ingesteld op het <aspSample:TextDisplayPart> element om de URL naar het Help-bestand op te geven.

<asp:CatalogZone ID="CatalogZone1" Runat="server">
  <ZoneTemplate>
    <asp:DeclarativeCatalogPart ID="DeclarativeCatalogPart1" 
      Runat="server">
      <WebPartsTemplate>
        <aspSample:TextDisplayWebPart 
          runat="server"   
          id="textwebpart" 
          title = "Text Content WebPart" 
          width="350px" 
          AllowClose="true"
          ExportMode="All"
          HelpMode="Modal"
          HelpUrl="TextWebPartHelp.htm" />            
      </WebPartsTemplate>
    </asp:DeclarativeCatalogPart> 
    <asp:PageCatalogPart ID="PageCatalogPart1" Runat="server" />
  </ZoneTemplate>

Nadat u de pagina in een browser hebt geladen, klikt u op het menu-item Catalogusmodus in de vervolgkeuzelijst Weergavemodus om de pagina over te schakelen naar de catalogusweergavemodus. Voeg het TextDisplayWebPart besturingselement toe aan de pagina, sluit de catalogus en retourneer de pagina naar de normale bladermodus. Als u in de titelbalk van het TextDisplayWebPart besturingselement op de vervolgkeuzelijst met werkwoorden klikt, hebt u toegang tot het Help-werkwoord om de Help-pagina te openen.

Opmerkingen

De HelpVerb eigenschap kan declaratief of programmatisch worden geopend. U kunt deze declaratief openen binnen een zone met behulp van het <asp:HelpVerb> element om de tekst, de beschrijving, of het werkwoord is ingeschakeld en andere kenmerken in te stellen. Het is echter niet nodig om een Help-werkwoord voor een zone te declareren, omdat deze standaard is ingeschakeld. De enige stap die nodig is om een Help-werkwoord in te schakelen voor weergave in het menu Werkwoorden van WebPart besturingselementen in een zone tijdens runtime, is het toewijzen van een waarde aan de HelpUrl eigenschap voor afzonderlijke WebPart besturingselementen.
