Utilizzare i marker di immagine durante il raggruppamento dei dati nei Smart Marker

Utilizzo di marcatori immagine durante la raggruppamento dei dati in Smart Markers

Il codice di esempio seguente crea un foglio di lavoro e poi aggiunge i seguenti tag del marker intelligente nelle celle D2, E2 e F2 rispettivamente

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

&=Person.City

&=Person.Photo(Picture:FitToCell)

Successivamente riempie l’origine dati con dati e chiama il metodo WorkbookDesigner.Process() per processare i tag del marker intelligente. Il codice utilizza queste immagini ossia moon.png e moon2.png ma è possibile utilizzare qualsiasi immagine
