HTML Client : property description

Question

Hi,

In SL client, the controls include both DisplayName and Description Properties.  That does not seem to be the case in HTML client.  contentItem.description is undefined.  Is there a way to get the description from the designer properties for use in js code of HTML client?

TIA,

Josh

Answer 1

Hi Josh,

For HTML Client, the LSML model file will be transformed into a model JSON object to be used by the JavaScript runtime (model.json under GeneratedResources). Unfortunately it looks like the Description of Content Items are not preserved in the model.json file, so it's impossible to get to them on the HTML Client. I'm checking to see if this is intentional or a bug. You can also log a Microsoft Connect bug for this issue.

Best regards,
Huy Nguyen

Thanks for logging the bug, Josh.

Answer 4

This is fixed in VS2013 RTM.  Here is a nice use of contentItem.description for help text:

vs 2013 update 2.

project is upgraded from vs 2013 (it seems to be the cause).

to have contentitem.description working you have to reset the value - like add  symbol - run - delete sumbol - run.
