PLinqServerModeSource Class

The data source for the DevExpress.XtraGrid.GridControl, DevExpress.XtraEditors.GridLookUpEdit and DevExpress.XtraEditors.SearchLookUpEdit controls that binds these controls to any enumerable source in Server Mode.

Namespace:DevExpress.Data.PLinq
Assembly:DevExpress.Data.v18.2.dll

Expanded Syntax

Expanded Remarks

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 System.ComponentModel.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 Source property. This property should be set in code.

  • Bind the control to the PLinqServerModeSource component.
Note

The LinqServerModeSource is a read-only data source.
