PL 400 Canvas Apps 3

Question 1

Which property of a Canvas App Text Input control should be set to make it act as a password field?

Accepted Answer

Mode = Password

Answer

Setting the Mode property of a Text Input to Password masks the entered characters with dots.

Question 2

In Canvas Apps, what does the Concurrent() function do?

Accepted Answer

Executes multiple formulas simultaneously to reduce load time

Answer

Concurrent() runs all its arguments at the same time, reducing total wait time when multiple data calls are independent.

Question 3

A Canvas App must filter a Dataverse table where a lookup column equals the current user's team. Which function retrieves the current user's Azure AD object?

Accepted Answer

User()

Answer

The User() function returns the current signed-in user's full name, email, and image within a Canvas App.

Question 4

What is the maximum delegation limit for data sources in Canvas Apps and how can a developer work around it for large datasets?

Accepted Answer

2000 records; use delegable filter predicates or server-side views

Answer

Canvas Apps retrieve up to 2000 records by default, but using delegable query functions pushes filtering to the server, handling millions of records correctly.

Question 5

A developer wants to prevent a Button from being clicked while a Patch operation is running. What is the best approach?

Accepted Answer

Set button DisplayMode = DisplayMode.Disabled while isLoading is true

Answer

Setting DisplayMode to DisplayMode.Disabled grays out the button and prevents interaction without hiding it from the user.
