XPBaseCollection.LoadAsync() Method

Asynchronously loads persistent objects of a specific type from the data store into the collection.

Namespace:DevExpress.Xpo
Assembly:DevExpress.Xpo.v19.1.dll

Expanded Syntax

Return value

Type: Boolean
true if the current method call started collection loading; otherwise, false.

Expanded Remarks

To reload data from a data store to the collection, call the Reload method.

Note

If the LoadingEnabled property is set to false, calling the LoadAsync method has no effect.

Expanded Example

The following example demonstrates how to asynchronously work with persistent objects.

In this example, a collection (xpcPersons) of Person objects is used as a data source for a grid control (gridPersons). The Update and Commit buttons (btnUpdate and btnCommit) allow users to update the grid control and store changes to a data store while continuing to interact with other UI elements. The accessibility of the grid control and these buttons is automatically updated within operation callbacks (CallBackLoadPersons and CallBackCommitChanges).
