AdomdDataProvider
Provides OLAP cube data access and operations using Microsoft Analysis Services through ADOMD.NET. This data provider enables pivot operations on multidimensional data sources with support for MDX queries, hierarchical dimensions, and cube-based aggregations.

Constructors
Initializes a new instance of the AdomdDataProvider class with default ADOMD client. Sets up the provider with deferred updates enabled for improved performance during configuration.
public AdomdDataProvider()
Properties
Gets a collection of AdomdAggregateDescription objects that specify how data should be aggregated within the intersection of row and column groups. These define the calculated values displayed in pivot cells.
public Collection<AdomdAggregateDescription> AggregateDescriptions { get; }
Gets a collection of AdomdGroupDescription objects that specify how the pivot data should be grouped by columns. Column groupings create the hierarchical structure displayed at the top of the pivot grid.
public Collection<AdomdGroupDescription> ColumnGroupDescriptions { get; }
Gets or sets the connection settings used for establishing connection to the Analysis Services data server. These settings include connection string, cube name, and authentication information required for ADOMD.NET access.
public AdomdConnectionSettings ConnectionSettings { get; set; }
The connection settings for the ADOMD data source.
Gets a collection of AdomdFilterDescription objects that specify how pivot items should be filtered. Filters are applied to restrict the data included in pivot calculations and display.
public Collection<AdomdFilterDescription> FilterDescriptions { get; }
Results
IPivotResults
Gets the current pivot calculation results containing the processed data from the OLAP cube. This property provides access to the aggregated and grouped data ready for display in pivot controls.
protected override IPivotResults Results { get; }
Overrides:
Gets a collection of AdomdGroupDescription objects that specify how the pivot data should be grouped by rows. Row groupings create the hierarchical structure displayed on the left side of the pivot grid.
public Collection<AdomdGroupDescription> RowGroupDescriptions { get; }
Gets the current state object representing the connection settings for this data provider. This state is used for field description retrieval and connection management.
public override object State { get; }
The ConnectionSettings object representing the current provider state.

Methods
Blocks the calling thread until the current refresh operation completes. This method is not implemented for ADOMD data provider as it uses asynchronous operations.
public override void BlockUntilRefreshCompletes()
This method is not implemented for asynchronous ADOMD operations.
Overrides:
Creates a field description provider for retrieving cube metadata and field information from the ADOMD data source. This provider is used to discover available dimensions, measures, and hierarchies in the connected cube.
protected override IFieldDescriptionProvider CreateFieldDescriptionsProvider()
A new AdomdFieldDescriptionProvider instance configured with the current connection settings.
Overrides:
Creates an aggregate description for the specified field that can be used in ADOMD pivot operations. The description is configured with the field name and initialized with the current provider context.
protected override IAggregateDescription GetAggregateDescriptionForFieldDescriptionCore(IPivotFieldInfo description)
The pivot field information to create an aggregate description for.
Returns:An AdomdAggregateDescription configured for the specified field.
Overrides:
Creates a filter description for the specified field that can be used in ADOMD pivot filtering operations. The description is configured with the field name and initialized with the current provider context.
protected override FilterDescription GetFilterDescriptionForFieldDescriptionCore(IPivotFieldInfo description)
The pivot field information to create a filter description for.
Returns:An AdomdFilterDescription configured for the specified field.
Overrides:
Creates a group description for the specified field that can be used in ADOMD pivot grouping operations. The description is configured with the field name and initialized with the current provider context.
protected override IGroupDescription GetGroupDescriptionForFieldDescriptionCore(IPivotFieldInfo description)
The pivot field information to create a group description for.
Returns:An AdomdGroupDescription configured for the specified field.
Overrides:
Performs the core refresh operation by generating MDX queries, executing them against the OLAP cube, and processing the results. This method handles field initialization, query generation, and result processing.
protected override void RefreshOverride()
