VirtualServerModeSource Events

A data source that features event-based data operations: async data load, sorting, filtering and infinite scrolling through records (in a bound Windows Forms GridControl).
Name Description

This event can be handled to provide an inner list that will be storage for rows fetched using the VirtualServerModeSource’s events. To enable CRUD operations in a bound Data Grid, you need to provide an inner list that supports these operations. If no inner list is supplied (or you do not handle the AcquireInnerList event), CRUD operations are disabled in the grid control.

CanPerformColumnServerAction Allows you to specify whether the requested filtering, sorting or summary calculation operation needs to be accepted or canceled.

Fires on initial data load and reload in the bound grid control, and when the data grid’s sort and filter configuration changes. Allows you to initialize the data source and (optionally) return an initial batch of records.

Disposed Occurs when the component is disposed by a call to the Dispose() method. Inherited from Component.
GetUniqueValues Allows you to provide values for columns’ filter dropdowns.
MoreRows Fires when a bound grid control asks the data source for a new batch of rows.
TotalSummary Fires when a grid control asks the data source to calculate total summaries.
