Sample for Web

In this example there is a Web Form containing a Web Component called Component, whose purpose is to load the links recently accessed by the user. They are dynamically loaded, meaning, for example, that they are loaded every time that the Web Panel object is Refreshed.

Event Refresh
    For &Index = &FirstTab To &LastTab
        Do 'LoadItem'

Sub 'LoadItem'
    &WebComponentUrl = &Tab.WebComponent
     Component.Object = CreateFromURL(&WebComponentUrl)

The variable &WebComponentURL is Character(1000).

The &Tab variable is based on  the TabOptions SDT  whose structure is as follows:

TabOptions SDT

Sample for Smart Devices

Event Start
   &Url = MyPanel.Link(&parm1)
   Component1.Object = CreateFromURL(&Url)


CreateFromURL function is available also in Smart Devices since GeneXus 15 upgrade 12.
