XPObjectSpaceProvider.GetDataStoreProvider(String, IDbConnection, Boolean) Method

Returns the data store provider.

Namespace: DevExpress.ExpressApp.Xpo

Assembly: DevExpress.ExpressApp.Xpo.v23.2.dll

NuGet Package: DevExpress.ExpressApp.Xpo

Declaration

C#

public static IXpoDataStoreProvider GetDataStoreProvider(
    string connectionString,
    IDbConnection connection,
    bool enablePoolingInConnectionString
)

VB.NET

Public Shared Function GetDataStoreProvider(
    connectionString As String,
    connection As IDbConnection,
    enablePoolingInConnectionString As Boolean
) As IXpoDataStoreProvider

Parameters

Name	Type	Description
connectionString	String	A string containing the database connection settings.
connection	IDbConnection	An IDbConnection object specifying the database connection.
enablePoolingInConnectionString	Boolean	true, if the connection pooling is enabled; otherwise, false.

Returns

Type	Description
DevExpress.ExpressApp.Xpo.IXpoDataStoreProvider	An IXpoDataStoreProvider object.

Remarks

You can pass the object returned by the static GetDataStoreProvider method to the XPObjectSpaceProvider constructor when registering the Object Space Provider in the XafApplication.CreateCustomObjectSpaceProvider event handler.

If you do not need to enable connection pooling, use another overload of this method that does not take the enablePooling parameter.
