PivotGridControl.OlapConnectionString Property

Gets or sets a connection string to a cube in an MS Analysis Services database.

Namespace: DevExpress.Xpf.PivotGrid

Assembly: DevExpress.Xpf.PivotGrid.v24.1.dll

NuGet Package: DevExpress.Wpf.PivotGrid

Declaration

public string OlapConnectionString { get; set; }

Property Value

Type Description
String

A String that specifies a connection string to a cube in an MS Analysis Services database.

Remarks

To retrieve data from an OLAP cube asynchronously, use the PivotGridControl.SetOlapConnectionStringAsync method to specify a connection string.

A sample connection string is shown below:

OlapConnectionString=”Provider=msolap;Data Source=localhost;Initial Catalog=Adventure Works DW;Cube Name=Adventure Works;Query Timeout=100;”

The connection string has the following parameters:

  • Provider - Identifies a data provider to be used. The “msolap” string identifies the latest version of Microsoft SQL Server Analysis Services (SSAS);

    Important

    Note that the Provider parameter is in effect only for the OLE DB provider for Analysis Services specified using the PivotGridControl.OlapDataProvider property.

  • Data Source - Specifies the name of a server that runs an instance of SSAS;
  • Initial Catalog - Specifies a data catalog that contains cubes;
  • Cube Name - Specifies the name of a cube that provides OLAP data;
  • Query Timeout (optional) - The maximum amount of time, in seconds, to wait for a query to SSAS to complete. If the parameter is set to 0, each query can last indefinitly.
