Today I came across the Page 13 "Email Editor" and I've seen the "Message" TextBox like this:
My first thought was - "it's probably some controladdin, let's see how it is done, so I can copy, paste and reuse it for my own purposes". So I went straight to AlAppExtensions repository on github to see the Page 13, but I haven't found any usercontrols there.
That was kind of strange for me. How it is implemented then?
So.. I've forked and cloned the AlAppExtensions repository, created clean container where I could compile the System App. Then I've copied the Page 13 "Email Editor" and saved under the name "Email Editor2" and Id = 1, like below:
but it still didn't work..
The magic behind this Message Box was bugging me, so I went back to the original Page 13 "Email Editor" and kept digging.
Once I've changed the Page id from 13 to some other, like 2 for example:
the magic was gone...
How did Microsoft implement this? On the Business Central platform site, with something like:
If (Page.id == 13)
