An AxDataSource component provides access to a data set in the AOT. The other components of the User Control will use the AxDataSource when retrieving or saving data in the data set.

Properties

The AxDataSource component has the following properties:

Property

Description

DataSetName

The data set the control is bound to.

EnableViewState

Indicates whether the control automatically saves its state for use in round-trips.

Expressions

The expressions that are bound to properties of the control.

ID

PersistState

When set to true, enables the control to persist state information for the dataset. Information persisted includes the following:

  • Dataset metadata

  • Calculated field values

  • Ax queries that are initially generated using the data source metadata

  • Temporary tables

  • Cursor position (active record) within each table

  • Uncommitted record buffer for the active record

The default value is true.

ProviderView

Role

  • Consumer - Data source receives context from other web parts

  • ProviderConsumer - Data source provides context to other web parts and receives context from other web parts.

A User Control can have multiple AxDataSource components. A maximum of one AxDataSource component for the User Control can act as a context provider. Multiple AxDataSource components can act as context consumers.
