Syntax
public class TableDescriptor : SourceListDescriptor, ICustomTypeDescriptor, IDisposable, IItemPropertiesSource, ITypedList, ITableEventsTarget
Remarks

TableDescriptor has several collections that can either be auto-populated from the underlying datasource or manually modified.

CollectionDescriptions
Fields The Fields collection is auto-populated from the underlying sourcelist's columns. Normally you will not modify this collection and just use it in its default auto-populated state. A fieldDescriptor holds a name, mapping name, and type of the column in the list.
Relations The Relations collection is auto-populated from the underlying sourcelist's relations. It will extract its information from an ADO.NET datasource. If you have other IList collections that are related, you can add RelationDescriptor manually to this collection and specify the primary and foreign key between the two lists.
ExpressionFields The ExpressionFields collection has ExpressionFields. You need to manually add ExpressionFields. This collection is not auto-populated from the datasource. A fieldDescriptor holds a name and the formula expression of the column.
GroupedColumns The GroupedColumns collections contains SortColumnDescriptor objects. It defines the grouping of the table. Each SortColumnDescriptor has a name that identifies a field in the Fields or ExpressionFields collection, a SortDirection property, and a FieldDescriptor property. The FieldDescriptor is Read-only and looked up in the Fields or ExpressionFields collection using the Name of the SortColumnDescriptor. A custom categorizer can be specified that allows you to group records into ranges of data, e.g. if you want to group by month.
Sortedcolumns The Sortedcolumns collection contains SortColumnDescriptor objects. It specifies the sort order of records within a group.
RecordFilters The RecordFilters collection has RecordFilterDescriptor objects. RecordFilters define selection criteria to hide or show records based on criteria.
Summaries The Summaries collection holds SummaryDescriptors. A SummaryDescriptor has a name, a mapping name that identifies the field (Fields or ExpressionFields collection) for which summaries should be calculated for, and a SummaryType property that defines the type of calculations to be performed. Possible SummaryTypes are: Count, BooleanAggregate, ByteAggregate, CharAggregate, DistinctCount, DoubleAggregate, Int32Aggregate, MaxLength, StringAggregate, Vector, DoubleVector, and Custom. When you specify the SummaryType.Custom type, you need to set the custom method through the CreateSummaryMethod property of the SummaryDescriptor. It is of type CreateSummaryDelegate and is called to create a instance of a summary object.

The Field and Relations collections feature auto-population on demand and reflect changes from the collection they depend on. The auto-population will happen when you access the contents of the collection, e.g. if you query its Count.

GroupedColumns and SortedColumns need to be manually initialized. They are not auto-populated.

SortedColumnDescriptor also lets you specify a custom comparer that implements the IComparer interface.

SortedItemsInGroup

Occurs after the records for a group were sorted.

Declaration
public event GroupEventHandler SortedItemsInGroup
Event Type
Type
GroupEventHandler
Remarks

The engine has a built-in optimization for sorting columns that allows it to perform the sorting on an on-demand basis group-by-group. Suppose you have a table with 200 different countries and then you change the sort order of city, it is not necessary to sort the whole table. Instead, the individual groups can be sorted when they are scrolled into view. SortingItemsInGroup and SortedItemsInGroup events are fired in such cases when a specific group was sorted on demand.

If the whole table was set dirty (see TableDirty), then the whole table is simply recategorized. In that case, only a CategorizedElements event is raised but no SortedItemsInGroup event.

SortingItemsInGroup

Occurs before the records for a group are sorted.

Declaration
public event GroupEventHandler SortingItemsInGroup
Event Type
Type
GroupEventHandler

SourceListListChanged

Declaration
public event TableListChangedEventHandler SourceListListChanged
Event Type
Type
TableListChangedEventHandler
Remarks

The reason for firing this event is to give a programmer chance to react to an System.ComponentModel.IBindingList.ListChanged event before the engine since there is otherwise no order guaranteed when an IBindingList raises a ListChanged event.

SourceListListChangedCompleted

Occurs after the Table processes the System.ComponentModel.IBindingList.ListChanged event of an attached source list.

Declaration
public event TableListChangedEventHandler SourceListListChangedCompleted
Event Type
Type
TableListChangedEventHandler
Remarks

The reason for firing this event is to give a programmer the chance to react to an System.ComponentModel.IBindingList.ListChanged event right after the engine since there is otherwise no order guaranteed when an IBindingList raises a ListChanged event.
