Get started

Watch this video to get started using CONTEXT() .

Sample usage

IN(CONTEXT("View"), LIST("Orders_Detail", "Orders_Form")) returns a Yes/No value that answers the question, is the currently-displayed view named Orders_Detail or Orders_Form ? This might be used in a Show_If column constraint to display a column only in specific views but hide it elsewhere. See also: IN() , LIST()

SWITCH(CONTEXT("Host"), "Device", "Tap below to:", "Browser", "Click below to:", "") returns different directions depending on whether the app is running from the native app on a device or from a browser. This might be used to generate a display name for a gallery view of launchers. See also: SWITCH()

CONTEXT("VIEWTYPE")="Detail" returns Yes if the current view is of type Detail.

Syntax

CONTEXT( option )

option - Must be set to one of the keywords described in the following table.

The following table lists the keywords and their return values.

Note : If an invalid option is provided, a null value is returned.

Keyword

Return value

AppName

Unique name of the app, including account ID, as used in app URLs. For example, MyApp-123456 .

Device

Universally unique identifier (UUID) of the device, intended to identify the mobile device running the native app. Used from a browser, the UUID is tied to the browser's local storage, not the device itself, and may change if the browser's cache is cleared. In the emulator of the app editor, the text expression-assistant-device-id is returned.

Host

Returns one of the following values:

Server when the expression is evaluated remotely on the server. Remote evaluation would include things like automation , security filters , or virtual columns computed during sync.
Browser when the expression is evaluated locally within the app running in a web browser or the app preview in the editor
Device when the expression is evaluated locally within the Android or iOS AppSheet apps or branded apps .

Local evaluation would include things like column constraints , slice filters , and virtual columns updated during editing.

OwnerEmail

Email of the app owner.

Table

Name of the table used by the current view.

View

Name of the view currently displayed to the user, or blank if no view is currently displayed (for example, in an automation)

ViewType

Type of the view currently displayed to the user, or blank if no view is currently displayed (for example, in an automation). For a list of valid view types, see View types .

Notes

The View and ViewType options are:

Not supported for Chat apps or embedded app view emails (dynamic emails).
May not work as expected if used in a virtual column's App formula expression . Except when editing a row (for example, in a form or with an action) and other limited circumstances, virtual column values are computed by the AppSheet server during a sync .

In each case, the server is unaware of the view currently visible to the user, so cannot provide the view name or type.
