Methods
| Name | Description |
|---|---|
| CreateObjRef(Type) | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. Inherited from MarshalByRefObject. |
| Dispose() | Releases all resources used by the Component. Inherited from Component. |
| Equals(Object, Object) static | Determines whether the specified object instances are considered equal. Inherited from Object. |
| Equals(Object) | Determines whether the specified object is equal to the current object. Inherited from Object. |
| GetHashCode() | Serves as the default hash function. Inherited from Object. |
| GetLifetimeService() | Retrieves the current lifetime service object that controls the lifetime policy for this instance. Inherited from MarshalByRefObject. |
| GetService(Type) protected | Returns an object that represents a service provided by the Component or by its Container. Inherited from Component. |
| GetType() | Gets the Type of the current instance. Inherited from Object. |
| InitializeLifetimeService() | Obtains a lifetime service object to control the lifetime policy for this instance. Inherited from MarshalByRefObject. |
| MemberwiseClone() protected | Creates a shallow copy of the current Object. Inherited from Object. |
| MemberwiseClone(Boolean) protected | Creates a shallow copy of the current MarshalByRefObject object. Inherited from MarshalByRefObject. |
| ReferenceEquals(Object, Object) static | Determines whether the specified Object instances are the same instance. Inherited from Object. |
| Refresh() | Reloads data from your source by firing the dedicated events (VirtualServerModeSource.ConfigurationChanged and VirtualServerModeSource.MoreRows). |
| ToString() | Returns a String containing the name of the Component, if any. This method should not be overridden. Inherited from Component. |
Events
| Name | Description |
|---|---|
| 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. |
| CanPerformColumnServerAction | Allows you to specify whether the requested filtering, sorting or summary calculation operation needs to be accepted or canceled. |
| 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. |
| 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. |
