Description

The function LINK allows “binding” a Web Panel to another Web Panel or URL. This function can be associated with the property link of a control inside any event of the Web Panel. So, when you click the control, the call to the Web Panel or URL referenced in the link is performed.

Notes:

• The Object can be selected using the option Insert/Object or Ctrl+Shift+J; in the example below, after writing "(" symbol.

  &var.link = link(
  

• If you want to call a URL, the URL must be entered between ‘’ (simple/double inverted commas).

  &var.link = link(‘http://www.genexusx.com’)
  

• If you want to make a link using an attribute that contains the URL or the name of the corresponding Web Panel, you must use the following syntax:

  &var.link = link(att:AplLnk)  // where AplLnk is an attribute of some table.

• Passing parameters is optional.

It can be used without associating it with the property link of a control.

&var = link(MasterLogin)
