Lesson 2 - Bind a Pivot Grid to an OLAP Cube

A cube is a multidimensional structure defined by its measures and dimensions. You can think of a measure as a data field in PivotGridControl, while a dimension can be represented by a column field or a row field. This tutorial will help you learn how to bind a pivot grid to an existing OLAP (OnLine Analytical Processing) cube. In this example, we will use the Adventure Works cube.

Note

This tutorial is based on the .NET Framework. For the .NET tutorial, refer to the following topic: Bind a Pivot Grid to an OLAP Cube (.NET)

Documentation: Migrate WPF Applications to .NET

To display data from an OLAP cube, do the following.

Specify a connection string to an OLAP cube.

1. Run MS Visual Studio. Create a new WPF Application project and add PivotGridControl as you did in Lesson 1.

2. Click the smart tag icon () displayed at the top-right of the pivot grid to invoke the Pivot Grid Control Tasks popup window.

   

3. In the invoked wizard, select OLAP Cube technology and click Next.

   

4. Select the ADOMD.NET as a data provider and click Next.

   

5. In the next window, select the MSOLAP provider and specify the Server Name as https://demos.devexpress.com/Services/OLAP/msmdpump.dll. Then, click the Retrieve Schema button.

   

   Make sure that the following parameters are specified.

   Provider	MSOLAP	Identifies the data provider to be used. The “MSOLAP“ string identifies the latest version of the OLE DB provider.
   Server Name	https://demos.devexpress.com/Services/OLAP/msmdpump.dll	Specifies either the name of a server that runs an instance of Microsoft SQL Server Analysis Services (SSAS), the path to a cube file or the path to a data pump.
   Catalog Name	Adventure Works DW Standard Edition	Specifies a data catalog that contains cubes.
   Cube Name	Adventure Works	Specifies the name of a cube that provides OLAP data.

   The image below demonstrates configured settings of the OLAP connection. Click Finish to close the wizard.

   

Create Fields

6. Click the pivot grid’s smart tag and use the Add Data Area Field menu item to add a new field to the Data Header Area. In a similar manner, add two fields both to the Column Header and Row Header areas.

   

7. To associate created fields with OLAP measures/dimensions, click the field’s smart tag icon. In the invoked menu, click the FieldName property ellipsis button to see existing data source fields.

   

   Select the following measures and dimensions for created fields.

   • For the data field, select the [Measures].[Internet Sales Amount] measure.
   • For the column fields, select the [Date].[Fiscal].[Fiscal Year] and [Date].[Fiscal].[Fiscal Quarter] dimensions.
   • For the row fields, select the [Customer].[Country].[Country] and [Customer].[City].[City] dimensions.

   After this, your XAML should look like the following. If it does not, you can overwrite your code with:
