Does this work? I have a simplified InfoPath form that receives a parameter via connection from the Query String URL Filter webpart. In my sample, I think my form should show the query string value.
Steps
- I published the form to a Forms library in office 365 with a connected property
- Created a Web Part Page
- Added the InfoPath Form webpart and configured it to point to my form
- Added a Query String URL Filter web part and configured it to look for a query string parameter called querystring
When I connect the two webparts, I don't get a secondary dialog to configure what value goes to what.
