ADOMD settings

ADOMD data provider requires a connection via ConnectionString property, in order to communicate with the data in the server.

The following table lists parameters that are necessary to establish a connection to the data in the server using the AdomdInitialSettings object. There are other optional parameters for authentication and security (not listed here). The binding code example below contains all these settings.

Parameter Description

provider

Used for connections that require SQL server data provider for Analysis Services ( Optional using current version). If specific version is required then this parameter needs to be specified.

"provider=MSOLAP.4;"

data source

Specifies the server instance ( Required ).

"data source=http://sampledata.infragistics.com/olap/msmdpump.dll;"

In addition to the connection string, mentioned above, you need to configure the following settings including the dimensions (rows, columns and measures) of the cube.

Parameter Description

catalog

Specifies the name of the Analysis Services database ( Required ).

Catalog = "Adventure Works DW Standard Edition"

cube

Cube name ( Required ).

Cube = "Adventure Works"

Rows

Rows dimensions.

Rows = "[Date].[Calendar]"

Columns

Column dimensions.

Columns = "[Product].[Category] "

Measures

Measures dimensions.

Measures = "[Measures].[Reseller Sales Amount]"

Code

ADOMD data provider communicates with Microsoft SQL Server Analysis Services using XML for analysis protocol. The following code example demonstrates how to configure the pivot grid to communicate with the data using ADOMD.

Note
Note:

This topic uses Infragistics sample data for demonstration purposes.

This example uses the data from the Infragistics OLAP server.

In C#:

AdomdInitialSettings settings = new AdomdInitialSettings();
StringBuilder sb = new StringBuilder();
sb.Append("provider=MSOLAP.4;");
sb.Append("data source=http://sampledata.infragistics.com/olap/msmdpump.dll;");
sb.Append("catalog=\"Adventure Works DW Standard Edition\";");
sb.Append("cube=\"Adventure Works\";");
options.ConnectionString = sb.ToString();
settings.Catalog = "Adventure Works DW Standard Edition";
settings.Cube = "Adventure Works";
settings.Rows = "[Date].[Calendar]";
settings.Columns = "[Product].[Category] ";
settings.Measures = "[Measures].[Reseller Sales Amount]";
AdomdDataSource adomdDs = new AdomdDataSource(settings);
ultraPivotGrid1.DataSource = adomdDs;

In Visual Basic:

Dim settings As New AdomdInitialSettings()
Dim sb As New StringBuilder()
sb.Append("provider=MSOLAP.4;")
sb.Append("data source=http://sampledata.infragistics.com/olap/msmdpump.dll;")
sb.Append("catalog=""Adventure Works DW Standard Edition"";")
sb.Append("cube=""Adventure Works"";")
settings.ConnectionString = sb.ToString()
settings.Catalog = "Adventure Works DW Standard Edition"
settings.Cube = "Adventure Works"
settings.Rows = "[Date].[Calendar]"
settings.Columns = "[Product].[Category] "
settings.Measures = "[Measures].[Reseller Sales Amount]"
Dim adomdDs As New AdomdDataSource(settings)
ultraPivotGrid1.DataSource = adomdDs

Adding MdxDataSelector

Overview

Although a separate control, the data selector ( MdxDataSelector) is an essential mechanism for the WinPivotGrid control; binding the data selector to the same data source as the pivot grid. The WinPivotGrid displays the list of dimensions and measures that the user can interact with at runtime by adding them to the pivot grid.

Note
Note:

If the data selector is not present at runtime, you will not be able to add the dimensions. You can only remove them from the pivot grid.

The following code example demonstrates binding data selector to the same data source as the pivot grid, using the data source object illustrated in the previous examples.

In C#:

mdxDataSelector1.DataSource = xmlaDs;

In Visual Basic:

mdxDataSelector1.DataSource = xmlaDs

The following screenshot illustrates the pivot grid with data selector both bound to XMLA data source. The same approach applied to ADOMD data source.
