Data Binding to Large Data via XPO
- 4 minutes to read
The Bootstrap Card View supports binding to large data sets using the XpoDataSource component provided by the XPO ORM library. This component fully supports database server mode (i.e., it delegates all data processing to the DB server), and only loads the records to be displayed on screen. This allows you to dramatically increase performance when working with large datasets.
Binding to Data
To bind Bootstrap Card View to a dataset via XpoDataSource in server mode, do the following.
Create and customize an XpoDataSource object. At design time, you can find this component in the Toolbox and add it to the page.
Note
To see an example, refer to How to Implement OData v4 Service with XPO (.NET Framework).
For information on generating persistent objects for existing data tables, see the Generating Persistent Objects for Existing Data Tables topic in the XPO help documentation.
- Set the XpoDataSource component’s XpoDataSource.ServerMode property to true. This enables database server mode.
- Bind the Bootstrap Card View to XpoDataSource.
- Provide connection settings to the target data store.
Data Stores Supported in Server Mode
In server mode, the Bootstrap Card View control uses methods provided by the eXpress Persistent Objects for .NET (XPO) to connect to a data store. It works with all the data stores supported by XPO. These are listed in the following table.

Note that the database provider assembly versions listed in the table above are the versions that have been tested with the current XPO version. Since XPO loads ADO.NET provider assemblies dynamically, you can use any specific version of the provider.
Note
XPO does not support tables with multi-column (compound) keys or indexes in ASE databases. To avoid exceptions when connecting to ASE databases containing these tables, use one-column keys or indexes.
Note
We do not recommend binding the Bootstrap Card View control to file-based databases (MS Access and VistaDB). These databases are slow, unlike the transaction speed, data security and integrity of server-based database engines (MSSqlServer).
Database Server Mode Limitations
In database server mode, the Bootstrap Card View does not have simultaneous access to bound data in its entirety. This imposes some limitations on the grid’s features, which are still available in regular binding mode. Please see the following topic for information on features that are not supported in server mode: Database Server Mode Limitations.
