CachedDataStoreClient Class
A cached data store provider (an ICachedDataStore implementation) for client applications transferring data via WCF.
Namespace: DevExpress.Xpo.DB
Assembly: DevExpress.Xpo.v24.1.dll
NuGet Packages: DevExpress.Win.PivotGrid, DevExpress.Win.TreeMap, DevExpress.Xpo
#Declaration
#Remarks
CachedDataStoreClient objects are automatically created to maintain a cache (DataCacheNode) on the client side when you create a data layer via the XpoDefault.GetDataLayer method call and pass a connection string to a service (an ICachedDataStoreService implementor, such as a CachedDataStoreService descendant) as a method parameter.
// Sample WCF service connection string.
string connectionString = "http://localhost:64466/Service.svc";
// GetDataLayer automatically creates
// a cached data store provider (and a cache) based on the connection string.
XpoDefault.DataLayer = XpoDefault.GetDataLayer(connectionString, AutoCreateOption.DatabaseAndSchema);
XpoDefault.Session = null;
If you are going to create a cache hierarchy at the client, you can manually create CachedDataStoreClient objects as shown below.
// Specifying the name of the endpoint in the client application's configuration file.
string bindingName = "...";
// Creating a cache (a node starting a cache hierarchy at the client).
DataCacheNode node = new DataCacheNode(new CachedDataStoreClient(bindingName));
// Checking connection.
node.ProcessCookie(DataCacheCookie.Empty);
XpoDefault.DataLayer = new SimpleDataLayer(node);
XpoDefault.Session = null;
