: Returns whether items in the underlying list can be edited.
: Returns or sets whether the method can be used to add items to the list.
This property is set to true when the underlying list represented by the property has a fixed size or is read-only.
The property is set to true and the event is not handled when the underlying list type does not have a default constructor.
: Returns whether the items can be removed from the underlying list.
: Returns the total number of items in the underlying list, filtered using the current value.
: Returns the currency manager associated with this .
: Returns the current item in the list.
Use the property to access the current item, but use the property to get the entire list. To determine the type of the current object, use the , or methods. To change the current item, set the property to a new integral value, or use one of the navigation methods such as .
: Returns or sets the list in the data source to which the connector currently binds to.
If the contains multiple lists (or tables) of data, you should set the property to the name of one of the sources. Setting this property raises the event
: Returns or sets the data source that the connector binds to.
The property can be set to a number of data sources, including types, objects, and lists of types. The resulting data source will be exposed as a list. The following table shows some of the common data sources and the resulting list evaluation.
| DataSource | List Result | | :--- | | null | An empty of objects. Adding an item sets the list to the type of the added item. | | null with set | Not supported, raises . | | Non-list type or object of type "T" | Empty of type "T". | | instance | containing the array elements. | | instance | An containing the items. | | List instance containing type "T" | instance containing type "T". |
In addition, can be set to other list types such as and and the will handle them appropriately. In this case, the type contained in the list should have a parameterless constructor. When setting a data source, if the supplied reference contains more than one list or table, you must set the property to a string that specifies the list to bind to. Setting this property raises the event.
: Returns or sets the expression used to filter the items in the underlying .
Typically used in complex data-binding scenarios, the property allows you to view a subset of the . Only underlying lists that implement the interface support filtering. When is not null, the passes this property to the underlying list. If you set this property during object initialization, the call will be deferred until after initialization is complete. To form a filter value, specify the name of a column followed by an operator and a value to filter on. The accepted filter syntax depends on the underlying data source. If the underlying data source is a , , or , you can specify Boolean expressions using the syntax documented for the DataColumn.Expression property. The value of the Filter property affects the value of the property. Additionally, the Filter value will persist when the data source changes. To stop filtering the , call the RemoveFilter method.
: Returns whether data binding is suspended.
: Returns whether the underlying has a fixed size.
: Return whether the underlying is read-only.
: Returns whether the items in the underlying are sorted.
: Returns whether access to the collection is synchronized (thread safe).
: Returns or sets the list element at the specified index in the underlying .
index is less than zero or is equal to or greater than .
: Returns the underlying data list.
The class uniformly handles different data sources. Ideally the property should be set to a general . However, sometimes it may be necessary to cast this property to a more specific type. The following table shows the underlying list type, which depends on the type or value of the data source.
| DataSource Type | Underlying List Description | | :--- | | and are null | An empty . | | is null, but is not null | None; an attempt to get the List will throw an . | | An instance | An . | | An instance | The return value from a call to the GetList() method of this instance. | | An instance | An . | | An instance | An . | | A non- instance of type "T" | A with one element. | | An instance | An with one element. | | An | An with the elements copied over. | | The type with of item type "T" | A . | | A Type that represents an or | An instance created by a call to the CreateInstance(Type) method of the class.

If the type retrieved is the interface, the underlying collection may be more complex, such as an or class.
: Returns or sets the index of the current item in the underlying .
When setting the property, out-of-range values are treated in the following manner:
Values greater than or equal to are treated as Count minus 1.
Changing the property will adjust the property.
: Returns or sets a value indicating whether events should be raised.
When the property is false, it suspends the raising of the events. This event indicates that the bound list has been modified in some way, including adding, deleting, inserting, or modifying items.
: Enables the automatic refresh of the source property after a data-bound value has been updated in the data source.
: Returns or sets the column names used for sorting, and the sort order for viewing the rows in the data source.
The property is a case-sensitive string that specifies the column names used to sort the rows, along with the . Columns are sorted ascending by default. Multiple columns can be separated by commas, such as "State, ZipCode DESC". To support sorting, the underlying must implement the or interfaces. This capability can be queried through the property. Multicolumn sorting is available when the property is true. Setting the Sort property will change the internal list depending on its type:
If the list is of type , the and properties are set in the internal list.
If the list is of type , the property is set.
The internal list's sort properties are only changed when the sort string is not null. The get accessor for this property will not retrieve the sort value of the internal list; instead, it will return the set accessor value. The value of the property will persist when the data source changes.
: Returns the collection of sort descriptions applied to the data source.
If the data source is not an , the property always returns null.
