Author's helpful tips and formula lessons
> The first screen (HomeScreen) looks like one well-designed graphic, but it's actually composed of an image in the top half, with a rectangle, a text label, and a button in the bottom half. Take a look at how nicely the text is rendered and how well the design elements come together.
> The second screen (RegistrationScreen) looks very custom, but the core of the screen is an edit form, with the text matching the rest of the design. An image provides a dramatic background while a rectangle with transparency set keeps attention on the form.
> The information collected on the RegistrationScreen is written to the Contacts entity in the Common Data Service. The information on the FavoriteActivitiesScreen is stored locally in a collection, but in a production app, you would typically write this data back to a custom entity.
Let's look at the formula used to write to the collection:
If((button1||button2||button3||button4||button5||button6||button7||button8||button9||button10)=true,ClearCollect(favorites,{favoriteactivities:If(button1=true,Button1_3.Text&", ")&If(button2=true,Button1_4.Text&", ")&If(button3=true,Button1_5.Text&", ")&If(button4=true,Button1_6.Text&", ")&If(button5=true,Button1_7.Text&", ")&If(button6=true,Button1_8.Text&", ")&If(button7=true,Button1_9.Text&", ")&If(button8=true,Button1_10.Text&", ")&If(button9=true,Button1_11.Text&", ")&If(button10=true,Button1_12.Text)});Navigate(ThanksScreen, Fade),UpdateContext({finish_error:true}))
That looks pretty complex, but here's the gist of what the formula is doing:
- If at least one button is clicked, write the value of each clicked button to the collection "favorites".
- If no buttons are clicked, set the context variable "finish_error" to true, so that an error message is displayed.
