Data is at the core of most apps you create with Experience Builder. Many widgets are data driven, and the builder provides unified data management. Widgets that consume the same data can be connected in an app. For example, you can synchronize record selections across multiple widgets and apply the same filter across widgets that are connected to the same data.
When you add data to an app in Experience Builder, it’s a specific instance of a data source connection. The benefits of this include the following:
- Updates to the original data source are synchronized in the apps you build.
- You can add the same data source multiple times. The connections become independent data in Experience Builder. Most of the data processing doesn’t affect other data processing (such as filtering and sorting), with the exception of updates that are made to the original data source (such as editing features and updating attributes).
Manage data
All the data you add to an app is listed in the Data panel of the builder workspace. You can manage the app’s data here and review related information, such as how many and which widgets are connected to the data and to which fields, when applicable. Use the Search box to filter the list to help you find a particular data source. Search results include sublayers for the web maps and web scenes you've added to the app.
Add data to an app
When adding data to an app, you can select web maps, web scenes, and layers stored as content items in ArcGIS, including the following:
- Hosted feature layers
- 3D Object and Point scene layers that support querying
- Scene layers with an associated feature layer
- Feature, scene, and map services
- Feature collections (excluding map notes and route layers)
You can browse and search for these data sources in your content, your groups, your organization, and content that’s shared publicly, including ArcGIS Living Atlas of the World. Layers from feature, scene, or map service URLs are also supported. In addition, when you add web maps and web scenes to an app, you can use their supported layers as a data source for widgets.
Note:
- When you add a web map or web scene as a data source, widgets can connect to its supported layers, such as tables, map image layers, tile layers, and group layers. Unsupported layer types aren't available in widget settings and don't appear on the details tab of the Data panel.
- Web maps and web scenes created with JSAPI 3.x that cannot be opened in Map Viewer Classic or Scene Viewer cannot be used as data sources. (If you add one of these items, it won’t be available to select and appears in the Data panel as an error card.)
You can add data to an app in the following ways:
- Before adding any widgets, click the Add data button in the Data panel to add data that will be used in the app. All data types supported in Experience Builder are listed in the Add data window.
- If you don’t add data before adding widgets, you can add data when configuring a widget by clicking Add data at the bottom of the Select data pane. Only the data type supported by the widget is available to add. The data you add when configuring a widget also appears in the Data panel and is available to select when configuring other widgets.
Note:
You can hide some sublayers in a service, a group layer, or a web map or web scene when you add data. You can also hide them under the detail panel of the service, group, web map, or web scene. The hidden layers won’t be available in the select data list when you configure widgets. You can only hide layers that aren't used yet.
Remove data
You can remove a data source using the Remove option on item cards in the Data panel. The data contained in the data source is also removed. When you remove data here, it is no longer available for widget configuration. If you remove data that’s already used by widgets, the app will no longer display information from that data, and all widgets connected to that data will be affected. You can delete the affected widgets when you delete the data, or you can reconfigure the widget settings by connecting other data later.
Data details and data views
The Data panel displays item cards with the item names for data that you add to the app. Labels with icons help you differentiate between data types. You can view additional details by clicking the link to open the item page for the original data source. You can change the name that appears on the item cards to something more relevant to the app (the source data is unchanged). Each card indicates the number of related widgets and layers in a map or scene. Clicking a data card opens a pane with more data details.
- For web maps, web scenes, services, and group layers, you can view the following details:
- Layers tab—Layers that the data source contains are listed. The layers are divided into two groups: In use shows layers that are selected in widget settings, and Others shows layers not yet connected to a widget. You can hide an unused layer so it won’t appear in the select data list when you configure a widget. Click the layer card to open a details pane.
- Widgets tab—Widgets that use the entire map, scene, service, or group layer directly are listed. Widgets that only use specified layers under the data aren’t listed here; they’re listed under the corresponding layer instead.
- For single layers (including those without sublayers), the following setting options and details are available:
- Data settings—Set filters, sort fields, and record limitations for the data. The filter settings here affect all its data views.
- Refresh settings—If the Auto refresh option is turned off, the data is refreshed only when you refresh the app or the builder. Turn on Auto refresh to refresh the data and get the latest features based on a specified time interval. You can set a custom time interval, or if the data comes from a web map, you can use the layer’s settings.
- Allow export—Provide options for users to export data at run time from connected widgets for which data actions are enabled.
Note:
For hosted feature layers, the app verifies that the user's role and item settings allow exporting the data.
- Data views tab—Create data views of supported feature layers and scene layers by adding filters, sort fields, and records limitations to control what appears in connected widgets. These settings only take effect within the view and don’t affect other data views or the source data.
Note:
Each layer also has built-in views that you can select when configuring data sources for the widget. The default view contains all the features. The selected features view contains features selected at run time. The automatically populated view is used for dynamic content settings with List widgets.
- View for empty selection—Check this box and click its Settings button to configure a view that displays when there are no features selected in a Selected features view. (Features in this configured view are not selected automatically.)
- Fields tab—Fields that are used by widgets are listed.
- Widgets tab—Widgets that use the layer in their settings are listed.
Use data
Data you add to an app, regardless of how you add it, is available to all supported widgets in that app. A data source used by one widget can be used by others. Record selection is synchronized throughout the app. In addition, filters on the default data view affect all widgets that use the data or its views. Filters on a specific data view only affect widgets that use the same data view.
Note:
When displaying a web map or web scene in a Map widget, a new web map or web scene view is created automatically, and this view is only used in the current widget. Data processing in the Map widget does not affect widgets using the same data source or its contained layers; however, the Map widget is affected by data processing on the default view.
The configuration panel for each widget includes a standard setting to connect to data. When you click Select data, a pane appears that lists the added data and output data in the app that the widgets support (hidden data is not listed). You can select data from the list or add more data to the app. Use the Search box to filter the list of options. Search results include sublayers for the web maps and web scenes you've added to the app. Some widgets support multiple data sources, so you can select more than one item in the list. If a widget can only be connected to one data source, click the existing data card to open the Select data pane where you can clear the selection and select another item.
The table below lists the widgets that you can connect to data and the supported data types for each.
| Widget | Supported data type* | Supported data number |
|---|---|---|
Branch Version Management | Feature service, map service (must be registered as versioned) | 1 or multiple |
Button** | Feature layer, scene layer | 0 or 1 |
Chart | Feature layer, scene layer | 1 |
Edit | Feature layer, scene layer (layers must be editable) | 1 or multiple |
Embed** | Feature layer, scene layer | 0 or 1 |
Feature Info | Feature layer, scene layer | 1 |
Filter | Feature layer, scene layer | 1 for each filter |
Image** | Feature layer, scene layer | 0 or 1 |
List | Feature layer, scene layer | 1 |
Map | Web map, web scene | 1 or 2 |
Map Layers | Web map, web scene | 0 or 1 |
Query | Feature layer, scene layer | 1 for each query |
Search | Feature layer, scene layer | 1 for each layer source |
Table | Feature layer, scene layer | 1 for each sheet |
Text** | Feature layer, scene layer | 0 or multiple |
Timeline*** | Web map, feature layer, map service layer | 1 or multiple |
*For a specific list of supported item types, see Add data to the app.
**Image, Text, Button, and Embed widgets are static by default. To display information from the data, turn on the Connect to data setting and specify the parameters with attributes, statistics, or expressions. For more information, see Dynamic content.
***The Timeline widget supports multiple feature layers or map service layers but only one web map at a time.
Output data
In addition to the data that you manually add to the app, the following widgets can process the original data and generate a new output dataset with the displayed results.
| Source widget | Output data type | Output datasets |
|---|---|---|
Chart | Feature layer | Chart statistics |
Directions | Feature layer | 1 each for stops, direction points, direction lines, and route |
Elevation Profile | Feature layer | 1 for each profile |
Query | Feature layer | 1 for each query |
Search | Feature layer | 1 for each locator source |
Utility Network Trace | Feature layer | 1 layer containing result area polygons |
When these source widgets are configured in the app, their output data is listed in the Select data pane when configuring other widgets. The output is created as a new data source, so filters and selections on the output data don’t affect the original data source.
Note:
If you remove a widget with output data that is being used by another widget, a warning message appears with a list of the related widgets. You can delete the related widgets or keep them to reconfigure with another data source later.
The schema of the output data is defined by its source widget:
- Chart—A statistic with attributes of the category field (if configured) and calculation results of number fields (it doesn't contain geometry)
- Query—A subset of records that meet the query criteria, with the fields as configured in its Results settings
- Search—The address for the search result from the corresponding locator source
The actual records in the output data are generated dynamically by the source widget at run time.
Data source views
Once the data is selected in the widget settings, you can choose one or more views from the drop-down list, based on the number of data sources the widget supports. A data source has the following view options:
- Default—A built-in view containing all the features in the data.
- Selected features—A built-in view containing features selected by the user at run time. The selected state of a feature is synchronized through all views. This view can be used to display an interaction result. For example, if it's configured for a List widget, the list only displays the selected records, and items in the list change dynamically as the selection changes. If there is no selection, the list displays a No data message until records are selected. You can also create a view for empty selection in the Data panel.
- Auto-populated—A built-in view that's available in dynamic content settings if a widget is added to a List widget and is connected to the same data view. This view only contains one feature that the list generates for each item in it.
- Data view—A subset of features that you can create with different filters, sort fields, and records limitations. You can preprocess a data source with multiple data views to control the data that appears in a widget without affecting other data views or the source data.
Note:
Output data doesn’t support adding custom data views.
Note:
The Page size setting on the Records tab is used for query performance and efficiency. It doesn't affect the total number of result features in widgets that support pagination. If the page size is smaller than the result, multiple requests are sent until all results are loaded.
The Default view is selected by default. You can also edit an existing view or create another view for the widget. Views created from a widget configuration panel are also available to select in other widget settings.
Dynamic content
Several widgets have settings you can use to display dynamic information from a connected data source. Examples include an attribute value of a specified feature; a statistic result of features meeting certain conditions; or an expression mixed with static strings, dynamic values, and computations.
Attribute
Get the attribute value of a feature in the specified data view using one of the following views:
- The views you set in the widget’s data source setting.
- The Selected features view of the original data layer. This view allows you to display the interaction results such as displaying the selected feature’s attributes.
- The automatically populated view if the widget is in a List widget (such as text, image, or button) and has the same data view as the List widget. This view contains only one feature that the list item represents.
If the view contains multiple features, the attribute value of the first feature is returned (based on the sort settings in the data view).
Statistics
Get the statistics results of the feature set defined by the specified data view.
Results can be the maximum, minimum, average, or sum value of a numeric field; the maximum or minimum value of a date field; the feature count of the feature set (using the unique ID field); or, if the service supports distinct count, the number of unique values for a field.
Use the statistics editor to provide custom labels for statistics. To set a label, replace the placeholder text, which acts as the default label and changes based on the operator and field you specify.
Expression
Use the expression editor to input text (format: “text”); numbers; field variables (format: {fieldname}); and functions including AVERAGE({fieldname}), COUNT({fieldname}), SUM({fieldname}), MAX({fieldname}), and MIN({fieldname}). Each part is concatenated with a plus sign. The expression returns the result of string concatenation and number calculation. For example, if you input 1+1, it returns 2 (number), but if you input 1 + “1”, it returns “11” (string).
As you type, suggestions appear that you can click to insert. Also, you can insert a field variable or a function by clicking the field names or function names listed under the input box.
Data on the Fields tab allows you to set the data view that the field variable represents. If a field variable is added as an independent part in the expression, the attribute value for that field is returned from the first feature in the specified data view.
If a numeric field variable or date field variable is used in a function—for example, AVERAGE({fieldname})—the function returns the statistic result of the data view for that field. For date fields, the expression builder only supports COUNT, MAX, and MIN functions.
You can format numbers in the expression by clicking the Number formatting button 
and turning on Number formatting. You can choose the number of decimal places to show, include a thousands separator, and add a unit from the data.
