Använda bildmarkörer samtidigt som data grupperas i smarta markörer

Använda bildmarkörer samtidigt som data grupperas i smarta markörer

Följande exempel skapar en arbetsbok och lägger sedan till följande smarta markörtaggar i cellerna D2, E2 respektive F2.

 &=Person.Name(group:normal,skip:1)

&=Person.City

&=Person.Photo(Picture:FitToCell)

Sedan fyller den datakällan med data och anroparWorkbookDesigner.Process() metod för att bearbeta smarta markörtaggar. Koden använder dessa bilder dvsmoon.png ochmoon2.png men du kan använda vilken bild som helst.
