Exempel
Följande kodexempel visar hur du använder InsertItemTemplate egenskapen för att skapa en anpassad mall för ett objekt i infogningsläge på en TemplateField fältrad i en DetailsView kontroll. Mallen visar en DropDownList kontroll som gör att användaren kan välja ett värde från en fördefinierad lista.

Kommentarer
Använd egenskapen InsertItemTemplate för att ange det anpassade innehåll som visas för ett objekt i infogningsläge i ett TemplateField objekt. Definiera innehållet genom att skapa en mall som anger hur objektet i infogningsläge återges.
Om du vill ange en mall börjar du med att öppna och stänga <InsertItemTemplate> taggar mellan inledande och avslutande taggar för elementet <TemplateField> . Lägg sedan till det anpassade innehållet mellan de inledande och avslutande <InsertItemTemplate> taggarna. Innehållet kan vara så enkelt som oformaterad text eller mer komplext (till exempel bädda in andra kontroller i mallen).
För att programmatiskt få åtkomst till en kontroll som definierats i en mall ska du först avgöra vilket objekt i den databundna kontrollen som TableCell innehåller kontrollen. Använd Controls sedan objektets TableCell samling för att komma åt kontrollen. Du kan också använda FindControl -metoden för TableCell objektet för att hitta kontrollen, om kontrollen har en ID angiven egenskap.
Note
Alla databundna kontroller stöder inte den här mallen Den här mallen stöds endast av databundna kontroller som gör att du kan infoga en post, till exempel DetailsView kontrollen.
