How to hook on "Reload linked file" event ?

[m.vallee]

Hi Revit API community,

I want some code to be executed each time the user clicks on "Reload" on a linked file.

I've had a look at PostCommands and Idling events but I haven't find the corresponding "trigger".

How would you do that ?

Thanks for your advice.

Dear Maxime,

Thank you for your query.

I do not think there is a dedicated event to catch that.

Here are some ideas that you might try out:

• Implement a dynamic model updater, specifying a specific linked file type (or all) as triggers, with ChangeTypeAny.
• Subscribe to the DocumentChanged event and check whether any recognisable elements get added, deleted or modified when you reload the link.

I hope this helps.

Best regards,

Jeremy

Hi Jeremy,

I tried your first idea, as it sounded quite promising.

The resulting behaviour is not far from what I want : my updater is triggered each time a RevitLinkInstance is loaded or unloaded. So if the user clicks on "Reload from", it is executed. But if the user simply clicks on "Reload", nothing happens.

Another point I missed when thinking about the process is that when linked files have been replaced/updated, reopening the main file *does* already refresh all the links, without any user manipulation... how could I detect these changes to execute some code...

Hi, 

Another ideas from the Revit API community ? 

Thanks in advance.
