VirtualServerModeSource Members

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

Top

Expanded Public Properties

Show: Inherited
  Name Description
Public property Container Gets the System.ComponentModel.IContainer that contains the System.ComponentModel.Component. (Inherited from System.ComponentModel.Component)
Public property RowType Gets or sets the type of object whose public properties identify columns for populating the bound control's column collection at design time.
Public property Site Gets or sets the System.ComponentModel.ISite of the System.ComponentModel.Component. (Inherited from System.ComponentModel.Component)
Top

Expanded Public Methods

Show: Inherited
  Name Description
Public method CreateObjRef Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from System.MarshalByRefObject)
Public method Dispose Releases all resources used by the System.ComponentModel.Component. (Inherited from System.ComponentModel.Component)
Public method Equals Determines whether the specified System.Object is equal to the current System.Object. (Inherited from System.Object)
Public methodStatic member Equals Determines whether the specified System.Object instances are considered equal. (Inherited from System.Object)
Public method GetHashCode Serves as a hash function for a particular type. System.Object.GetHashCode is suitable for use in hashing algorithms and data structures like a hash table. (Inherited from System.Object)
Public method GetLifetimeService Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from System.MarshalByRefObject)
Public method GetType Gets the System.Type of the current instance. (Inherited from System.Object)
Public method InitializeLifetimeService Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from System.MarshalByRefObject)
Public methodStatic member ReferenceEquals Determines whether the specified System.Object instances are the same instance. (Inherited from System.Object)
Public method Refresh Reloads data from your source by firing the dedicated events (ConfigurationChanged and MoreRows).
Public method ToString Returns a System.String containing the name of the System.ComponentModel.Component, if any. This method should not be overridden. (Inherited from System.ComponentModel.Component)
Top

Expanded Public Events

Show: Inherited
  Name Description
Public event AcquireInnerList

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.

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

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.

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