Catalog Data Sources

How it works

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 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[]
