GetList. Retrieves lists of objects.

GetList

GetList(Ektron.Cms.Content.LibraryCriteria)

Retrieves lists of objects.

Authenticated users

CMS Administrators

To create anonymous user access with this method, set the API access mode (ApiMode) in the Manager class when instantiating the class.

Fields

*=Required

* Library Data Property
* Object Value

Parameters

criteria. LibraryCriteria used to retrieve libraries.

Criteria use

The DataProperty enum works with its criteria class and defines the properties that the Manager class uses to filter and order. Specify zero (0) or more criteria to retrieve the objects you want. The criteria object also lets you set the number of items to return, define paging data, and modify sorting.

Criteria objects

Condition. The Logical operator to apply to the filters. The default value is "AND". The criteria condition controls the operator for the default filter group and the AND-ing\Or-ing the filter groups together.
```
public Ektron.Cms.Common.LogicalOperation Condition { set; get; }
```
FilterGroups. Gets a list of filter groups. Filter groups can be created to do filter grouping (that is, parentheses in the where clause). The groups use the criteria's condition like other filters, but can use their own condition internally.
```
public 
  System.Collections.Generic.List<CriteriaFilterGroup<ActivityCommentProperty>> 
  FilterGroups { get; }
```
Filters. Lists of filters defined in this criteria object. To add new Filters, you can add them here or use the AddFilter method (recommended).
```
public 
  System.Collections.Generic.List<CriteriaFilter<ActivityCommentProperty>> 
  Filters { get; }
```

GroupByField. The group by field to apply to the results.

public 
  Ektron.Cms.Activity.ActivityCommentProperty 
  GroupByField { set; get; }

OrderByDirection. Sets the order direction (ascending or descending).

public EkEnumeration.OrderByDirection 
  OrderByDirection { set; get; }

OrderByField . Set the property used to order the results.

public Ektron.Cms.Activity.ActivityCommentProperty 
  OrderByField { set; get; }

PagingInfo. By default, page size is 50 for improved performance. Example paging Info:

PagingInfo pageinfo = new PagingInfo();
pageinfo.CurrentPage=1;
pageinfo.RecordsPerPage = 100;
criteria.PagingInfo = pageinfo;

Constructor(property, orderbyDirection)

Sorts the results by a property in ascending or descending order.

AddFilter(property, operator, value)

Filters the results based on the conditions defined in this method.

criteria.AddFilter(Property.ObjectType, 
  CriteriaFilterOperator.EqualTo, Objectvalue);

LogicalOperation Condition

Filters the array of items based on the logical condition set in the AddFilter properties.

criteria.AddFilter(Property.ObjectType, 
  CriteriaFilterOperator.EqualTo,Objectvalue);

List<CriteriaFilterGroup> FilterGroups

Binds data to a listview or gridview.
