DataLayoutControl.FieldRetrieved Event

Fires after a layout is generated at runtime. Allows you to customize settings of individual generated layout items and editors.

Namespace:DevExpress.XtraDataLayout
Assembly:DevExpress.XtraLayout.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type DevExpress.XtraDataLayout.FieldRetrievedEventArgs containing data related to this event.

Expanded Remarks

The FieldRetrieved event fires after a layout is generated at runtime in the following cases:

  • When the RetrieveFields method is called.
  • When automatic layout generation is invoked at runtime. This feature is invoked each time the DataSource property is set to a new value, provided that the AutoRetrieveFields property is enabled.

The FieldRetrieved event fires for each generated layout item. Handle this event to customize settings of individual layout items and editors.

Expanded Example

Show Me

A complete sample project is available in the DevExpress Code Examples database at http://www.devexpress.com/example=T246872.

This example shows how to handle the FieldRetrieving and FieldRetrieved events to customize binding information, and settings of auto-generated layout items and embedded editors.

In the example, the FieldRetrieving event is handled to assign a ComboBoxEdit control for editing the ZipCode field. Items are added to the ComboBoxEdit after the editor is created (in the FieldRetrieved event).

In the FieldRetrieving event handler, the DataSourceUpdateMode parameter is set to OnPropertyChanged. For instance, this forces the "Full Name" field to be updated immediately on typing text in the "First Name" and "Last Name" fields.

The following image shows the result:
