public class PLinqServerModeSource :


Server mode allows a data-aware control to rapidly work with large datasets. Loading records in small portions on demand and performing data-aware operations on the data server side are the key features of server mode. When the control needs to display a specific portion of data, it calls a specific method of the bound server mode data source. This method sends a corresponding request to the data store, and upon receiving the results, passes them back to the control. The PLinqServerModeSource component implements the IListSource interface, and can be used as a data source for a control supporting the server mode feature.

Use PLinqServerModeSource to bind a server-mode enabled control to an enumerable collection via Parallel LINQ to Objects. For this purpose, perform the following steps.

  • Specify the required collection via the PLinqServerModeSource.Source property. This property should be set in code.

    public Form1() {
        plinqServerModeSource1.Source = myCustomerCollection;
  • Bind the control to the PLinqServerModeSource component.


The LinqServerModeSource is a read-only data source.
