LookupTable::CreateLookupTablesMultiLang Method

Creates multilanguage custom field lookup tables and corresponding code masks.

Namespace:  [LookupTable Web service]
Service reference: http://ServerName:32843/[Project Service Application GUID]/PSI/LookupTable.svc
Web service reference: http://ServerName/ProjectServerName/_vti_bin/PSI/LookupTable.asmx?wsdl

Parameters

ltds
Type: [LookupTable Web service].LookupTableMultiLangDataSet
LookupTableMultiLangDataSet containing data in the datatables.
validateOnly
Type: System.Boolean
Validate only, do not create.
autoCheckIn
Type: System.Boolean
If true, check in after creating.

If you create a non-text lookup table such as type Cost, Date, Duration, or Number, you still need to programmatically create a code mask. Project Web App hides the code mask for non-text lookup tables on the New Lookup Table page, but creates a code mask for the call to CreateLookupTable. The Example section includes sample code that creates a Duration lookup table. For more examples, see Using the ProjTool Test Application in Project Server 2010.

The pre-event for CreateLookupTables is LookupTableEventReceiver.OnCreating and the post-event is OnCreated.

For example, the e parameter in an OnCreating event handler exposes a LookupTableMultiLanguageDataSet object. The following code shows examples of how to get data from different tables such as LookupTableLanguages, LookupTables, and LookupTableValues.

C#
Copy 
using PSLibrary = Microsoft.Office.Project.Server.Library;
. . .
public class LookupTableEvents : LookupTableEventReceiver
{
    public override void OnCreating(PSLibrary.PSContextInfo contextInfo, 
        LookupTablePreEventArgs e)
    {
        int lutLanguage = 
            (int)e.LookupTableInformation.LookupTableLanguages.Rows[0]["LCID"];
        Guid lutMultiUid = 
            (Guid)e.LookupTableInformation.LookupTables.Rows[0]["LT_UID"];
        string lutMultiValue = 
            (string)e.LookupTableInformation.LookupTableValues.Rows[0]["LT_VALUE_TEXT"];
        . . .
    }

To use datasets in event handlers, set a reference to the Microsoft.Office.Project.Schema.dll assembly. For more information, see How to: Write and Debug a Project Server Event Handler.

Caution noteCaution

When you use the PSI to create or update a number lookup table, do not add values that have more than two decimal places.

The CreateLookupTablesMultiLang method enables you to save a number with more than two decimal places. When you create a custom field that uses the number lookup table, Project Professional 2010 rounds the number custom field values to two decimal places and shows them as strings in the drop-down list to select a value. When you select a value, Project Professional 2010 converts the string back to a number. The process shows an error, because the numeric value with only two decimal places does not exist.

Project Server Permissions

Permission

Description

ManageEnterpriseCustomFields

Allows a user to modify the definitions of Enterprise custom fields and lookup table values. Global permission.

The following code fragment creates a lookup table named Test Duration LUT of type Duration. LookupTableWS is an arbitrary name for a reference to the LookupTable Web service. To test the code, add it to a sample console application. For more information, see Prerequisites for ASMX-Based Code Samples.

The comments include names of the tables changed in the Published database after the call to CreateLookupTablesMultiLang.
