Dimension(String, Int32) Constructor

Initializes a new instance of the Dimension class with the specified group index and binds it to the specified data member.

Namespace: DevExpress.DashboardCommon

Assembly: DevExpress.Dashboard.v19.2.Core.dll

Declaration

C#

public Dimension(
    string dataMember,
    int groupIndex
)

VB.NET

Public Sub New(
    dataMember As String,
    groupIndex As Integer
)

Parameters

Name	Type	Description
dataMember	String	A String that identifies the data member to which this Dimension should be bound. This value is assigned to the DataItem.DataMember property.
groupIndex	Int32	An integer value that specifies the index of the group which owns this Dimension. This value is assigned to the Dimension.GroupIndex property.

Remarks

The data member identifier passed via the dataMember parameter should consist of the data table name and the column name, dot separated. For instance, the Street Address column from the Customers table is identified as “Customers.Street Address”.

If a data source has been specified in code, particular data fields can be custom objects. In this instance, the identifier is a chain of property names, like “Customers.City.Population”.

Note that aliases specified in the Query Builder are not used in data member identifiers. Use actual column names instead.

Note

You can use the groupIndex parameter to combine the dimensions contained in a specific OLAP hierarchy.

Example

The following example demonstrates how to bind the dashboard to the OLAP cube using DashboardOlapDataSource.

DashboardOlapDataSource allows you to establish a connection to the OLAP cube by specifying a connection string.
