This topic describes the Catalog Data Sources features. Classes in this topic are in the Mediachase.Commerce.Catalog.DataSources namespace.
The following image shows an overview of the Catalog Data Sources API structure.
Example: creating a CatalogIndexSearchDataSource
private CatalogIndexSearchDataSource CreateCatalogIndexSearchDataSource()
{
// Set up CatalogEntrySearchCriteria object.
SearchFilterHelper sfHelper = SearchFilterHelper.Current;
string keywords = Request.QueryString["search"];
SearchSort sortObject = CatalogEntrySearchCriteria.DefaultSortOrder
CatalogEntrySearchCriteria criteria = sfHelper.CreateSearchCriteria(keywords, sortObject);
// Set up CatalogIndexSearchDataSource object.
int startIndex = SomeListView.StartRowIndex;
int recordsToRetrieve = pageSize;
int count = 0;
CatalogEntryResponseGroup responseGroup = new CatalogEntryResponseGroup(CatalogEntryResponseGroup.ResponseGroup.CatalogEntryInfo);
bool cacheResults = true;
TimeSpan cacheTimeout = new TimeSpan(0, 0, 30);
//...
CatalogIndexSearchDataSource dataSource = null;
// No need to perform search if there are no catalogs specified.
if (criteria.CatalogNames.Count != 0)
{
Entries entries = sfHelper.SearchEntries(criteria, startIndex, recordsToRetrieve, out count, responseGroup, cacheResults, cacheTimeout);
dataSource = new CatalogIndexSearchDataSource();
dataSource.TotalResults = count;
dataSource.CatalogEntries = entries;
}
return dataSource;
}
After creating the CatalogIndexSearchDataSource object, you can bind it to an ASP.NET server control that supports data binding, such as the ListView control. When this is done, you have access to a collection of catalog entry results.
Example: accessing a catalog entry results collection
SomeListView.DataSource = CatalogIndexSearchDataSource
CatalogIndexSearchDataSource.CatalogEntries // propety of type Entries
CatalogIndexSearchDataSource.CatalogEntries.Entry // array of type Entry[]
