Hi Andrew,


You have the image to show what is on variable BinaryDataVar, so you need to set the value that is on the database after the query.

For that, you need to create a OnAfterFetch event on the GetMoviesByActorId query:

And then update the BinaryDataVar with the image on the database:

I missed that part.

You have to add a handler on the OnChange event of the Upload widget:

And there, you can get the extension from the name and do the validation you want. If the extension is not the right one, you reset the Name and BinaryDataVar variables and show an error message to the user:


I don't know which extensions you want, so my example and OML in attachment considers any extension other than .jpg and .png as invalid.
