Namespace: Microsoft.PerformancePoint.Scorecards
Assembly: Microsoft.PerformancePoint.Scorecards.ServerCommon (in Microsoft.PerformancePoint.Scorecards.ServerCommon.dll)

Syntax

'Declaration
Public Function GetListItems ( _
    listUrl As String _
) As FirstClassElementCollection
'Usage
Dim instance As BIMonitoringServiceApplicationProxy
Dim listUrl As String
Dim returnValue As FirstClassElementCollection

returnValue = instance.GetListItems(listUrl)

public FirstClassElementCollection GetListItems(
    string listUrl
)

Parameters

listUrl
Type: System.String

The server-relative URL of the document library or list that contains the objects. Example: /BI Center/Lists/PerformancePoint Content.

Return Value

Type: Microsoft.PerformancePoint.Scorecards.FirstClassElementCollection
The FCOs from the specified repository.

Implements

IBIMonitoringServiceApplicationProxy.GetListItems(String)

Remarks

PerformancePoint Services in Microsoft SharePoint Server 2010 uses SharePoint document libraries and lists as its repository. It stores data sources in a document library, and it stores other FCO types in a list.

Examples

The following code example is an excerpt from the PerformancePoint Services SDK Reference Sample. The sample runs on the front-end web server within a PerformancePoint Services application instance; therefore it calls GetListItems(String) to retrieve all data sources from a specified document library.

Before you can compile this code example, you must do the following:

Configure your development environment and create a C# class library project in Visual Studio. For information about configuring a development environment, see Setting Up the Development Environment for SharePoint 2010 on Windows Vista, Windows 7, and Windows Server 2008.
Add the Microsoft.PerformancePoint.Scorecards.Client, Microsoft.PerformancePoint.Scorecards.ServerCommon, Microsoft.SharePoint, and System.Web.Services DLLs as references to your project. For more information about PerformancePoint Services DLLs, see PerformancePoint Services DLLs Used in Development Scenarios.
