public LookupTableMultiLangDataSet ReadLookupTablesMultiLang(
	string xmlFilter,
	bool autoCheckOut


Type: System.String

XML filter to read specific data.

Type: System.Boolean

If true, check out for making changes.

The primary DataTable in a LookupTableMultiLangDataSet is the LookupTablesDataTable.


The xmlFilter parameter works with the Criteria operators to filter rows only in the primary LookupTablesDataTable. For example, you cannot use filter with the ReadLookupTables method to filter rows in the LookupTableLanguagesDataTable. If you try to filter rows in a secondary DataTable, the PSI returns a FilterInvalid exception.

However, you can use the Fields.Add method to filter columns in the primary LookupTablesDataTable and the in secondary LookupTableLanguagesDataTable, LookupTableMaskStructuresDataTable, LookupTableMaskValuesDataTable, LookupTableStructuresDataTable, or LookupTableValuesDataTable.

For more information about the xmlFilter parameter, see How to: Use a Filter Parameter with PSI Methods.
