ProviderID property in NAV 2009

ProviderID property is specifically for the RoleTailored client and not supported in the Classic Client.

This property enables you to create a link from a Repeater or any other type of control to a Factbox. It could also be used to link two FactBoxes. For example, the Sales Order page (42), uses this property to update the Sales Line FactBox by creating a ProviderID link to the SalesLines FastTab.

For Example:

If you open the Page 42 in design mode, <Control1906127307> “Sales Line FactBox” control ProviderID value is 58 which is the ID of the SalesLines control in the same page.

 

That is the reason if you open the Sales Order page in Role Tailored Client, Sales Line Factbox details are updated based on the Sales line you selected.
