Examples

The following example uses CustomFieldWS as the name of a web reference to the Custom Fields web service (https://ServerName/ProjectServerName/_vti_bin/psi/CustomFields.asmx). The btnCustomField_Click event handler is for a button on a Windows Form application, such as LoginDemo in the Project SDK download.

using PSLibrary = Microsoft.Office.Project.Server.Library;
. . .
private Guid customFieldUid;
. . .
private void btnCustomField_Click(object sender, EventArgs e)
{
    string cfName = "Test Task Cost";
    Guid entityTypeUid = new Guid(PSLibrary.EntityCollection.Entities.TaskEntity.UniqueId);
    lookupTableUid = Guid.Empty;
    ltRowDefaultUid = Guid.Empty;
    byte cfType = (byte)PSLibrary.CustomField.Type.COST;
    byte rollup = (byte)PSLibrary.CustomField.SummaryRollup.Sum;

    customFieldUid = CreateCustomField(
        customFields, cfName,
        entityTypeUid, lookupTableUid, ltRowDefaultUid,
        cfType, rollup);
}

// Test method for creating a custom field.

    CustomFieldsWS.CustomFieldDataSet.CustomFieldsRow cfRow =
        customFieldDataSet.CustomFields.NewCustomFieldsRow();
    Guid cfUid = Guid.NewGuid();

    cfRow.MD_PROP_UID = cfUid;
