Comentários
The number of labels returned for each item depends on the number of language packs installed by the organization. If no additional language packs are installed, there will only be labels for the organization base language. For best performance when additional language packs are installed you can limit labels to those that correspond to the user’s language preference. These preferences can be determined using the values returned by the client-side context getUserLcid function or by querying the UserSettings.UILanguageId value.
The following example shows those portions of the Sample: Query Metadata and Detect Changes which deal with setting the LabelQueryExpression.
private Guid _userId;
private int _languageCode;
...
_userId = ((WhoAmIResponse)_service.Execute(new WhoAmIRequest())).UserId;
_languageCode = RetrieveUserUILanguageCode(_userId);
...
protected int RetrieveUserUILanguageCode(Guid userId)
{
QueryExpression userSettingsQuery = new QueryExpression("usersettings");
userSettingsQuery.ColumnSet.AddColumns("uilanguageid", "systemuserid");
userSettingsQuery.Criteria.AddCondition("systemuserid", ConditionOperator.Equal, userId);
EntityCollection userSettings = _service.RetrieveMultiple(userSettingsQuery);
if (userSettings.Entities.Count > 0)
{
return (int)userSettings.Entities[0]["uilanguageid"];
}
return 0;
}
...
//A label query expression to limit the labels returned to only those for the user's preferred language
LabelQueryExpression labelQuery = new LabelQueryExpression();
labelQuery.FilterLanguages.Add(_languageCode);
