CreateCustomObjectSpaceProviderEventArgs.IsObjectSpaceProviderOwner Property

Specifies whether or not the Object Space Provider is disposed of when the application is disposed of.

Namespace: DevExpress.ExpressApp

Assembly: DevExpress.ExpressApp.v21.1.dll

Declaration

public bool IsObjectSpaceProviderOwner { get; set; }

Property Value

Type Description
Boolean

true, if the Object Space Provider is disposed of together with the application; otherwise, false.

Remarks

When Object Space Providers are created using the XafApplication.CreateCustomObjectSpaceProvider event, providers and their connections are disposed of together with their application (e.g., on re-logon). Set the IsObjectSpaceProviderOwner parameter to false to cancel disposal of providers together with the application in this scenario

private void Instance_CreateCustomObjectSpaceProvider(object sender, CreateCustomObjectSpaceProviderEventArgs e) {
    IXpoDataStoreProvider dataStoreProvider = null;
    if(Application["DataStoreProvider"] != null) {
        dataStoreProvider = Application["DataStoreProvider"] as IXpoDataStoreProvider;
        e.ObjectSpaceProvider = new SecuredObjectSpaceProvider((ISelectDataSecurityProvider)WebApplication.Instance.Security, dataStoreProvider, true);
    }
    else {
        if(!String.IsNullOrEmpty(e.ConnectionString)) {
            string connectionString = DevExpress.Xpo.XpoDefault.GetConnectionPoolString(e.ConnectionString);
            dataStoreProvider = new ConnectionStringDataStoreProvider(connectionString, true);
        }
        else if (e.Connection != null){
            dataStoreProvider = new ConnectionDataStoreProvider(e.Connection);
        }
        Application["DataStoreProvider"] = dataStoreProvider;
        e.ObjectSpaceProvider = new SecuredObjectSpaceProvider((ISelectDataSecurityProvider)WebApplication.Instance.Security, dataStoreProvider, true);
    }
    e.IsObjectSpaceProviderOwner = false;
}
