DataSet

  • Artigo

Provides properties and methods to work with data on grids and views.

Available for

Model-driven and canvas apps.

Properties

columns

The set of columns available in this dataset. Supported in both model-driven and canvas apps.

Type: Column[]

error

Whether an error occurred in data retrieval. Supported in both model-driven and canvas apps.

Type: boolean

errorCode

The error code associated with the last encountered error, if applicable.

errorMessage

The error message associated with the last encountered error, if applicable.

Type: number | string

filtering

The column filtering for the current query. Supported in both model-driven and canvas apps. Filtering can be configured for a dataset by setting context.parameters.[dataset_property_name].filtering.setFilter(<filterExpression>). Once filter is set, calling context.parameters.[dataset_property_name].refresh() retrieves the filtered data from the data source.

Note

Filtering feature is only available to Dataverse data source.

Type: Filtering

linking

Defines the linked table information. Supported only in model-driven apps.

Type: Linking

loading

Indicates whether the dataset is loading or not. Supported in both model-driven and canvas apps.

Type: boolean

paging

Pagination status and actions. Supported in both model-driven and canvas apps. Paging info can be accessed and configured for a dataset using context.parameters.[dataset_property_name].paging .

Note

Dataverse data source does not return the totalRecordCount in paging object for canvas apps. Instead, it uses hasNextPage and hasPreviousPage to check if there are more records to be fetched.

Dataset components can use context.parameters.[dataset_property_name].paging.setPageSize(pageSize) to change the number of records retrieved per page.

Type: Paging

records

Map of IDs to the full record object. Supported in both model-driven and canvas apps.

Type: EntityRecord

sortedRecordIds

IDs of the records in the dataset, order by the query response result. Supported in both model-driven and canvas apps.

Type: string[]

sorting

The sorting status for the current query. Supported in both model-driven and canvas apps. Sorting can be configured for a dataset by setting context.parameters.[dataset_property_name].sorting = [SortStatus]. Once sorting is configured, calling context.parameters.[dataset_property_name].refresh() retrieves the sorted data from the data source.

Note

Sorting feature is only available to Dataverse data source. Also, if sorting is re-configured it will reset the filter context.parameters.[dataset_property_name].filtering

Type: SortStatus[]

Methods

Method Description Available for
addColumn Adds column to the column set. Model-driven apps
clearSelectedRecordIds Clears the selected record ids list. Model-driven and Canvas apps
delete Delete the records from data source. Canvas apps
getCommands The commands for the dataset. Canvas apps
getDataSetCapabilities The capabilities for the dataset. Canvas apps
getSelectedRecordIds Retrieves all the selected record IDs. Model-driven and Canvas apps
getTargetEntityType Returns the target table type name. Model-driven and Canvas apps
getTitle Retrieves the view display name used by the dataset property. Model-driven and Canvas apps
getViewId Returns the Id of view used by dataset parameter. Model-driven and Canvas apps
newRecord Initialize a local record object for control to set the value. The control needs to invoke the save() method on the newly created record to persist the change. Canvas apps
openDatasetItem Open dataset item for a given EntityReference. It checks if there is a command with command button id Mscrm.OpenRecordItem. If exists, it executes the command, otherwise it just navigates to the associated form of the EntityReference. Model-driven and Canvas apps
refresh Refreshes the dataset based on filters, sorting, linking, new column. Additionally, refresh will reset paging to page 1. Model-driven and Canvas apps
retrieveRecordCommand Retrieve record's associated commands. If there are multiple datasets in the manifest, retrieveRecordCommand returns the commands for the first dataset. Model-driven
setSelectedRecordIds Set the ids of the selected records. Model-driven and Canvas apps

Lookup columns

Dataverse table's lookup columns can now be retrieved. For canvas apps, if a lookup column is included in the dataset, all columns in the referred record are retrieved. GetFormattedValue returns the JSON string for this column. GetValue method returns the JSON object directly.
