RepositoryItem.EditValueChanging Event

Fires when the editor's value is about to be changed.

Namespace:DevExpress.XtraEditors.Repository
Assembly:DevExpress.XtraEditors.v17.2.dll

Expanded Syntax

Expanded Event Data

The event handler receives an argument of type ChangingEventArgs containing data related to this event.

The following ChangingEventArgs properties provide information specific to this event.
Property Description
Cancel Gets or sets a value indicating whether the event should be canceled.
NewValue Gets or sets the value which is about to be assigned to the editor.
OldValue Gets the editor's value.

Expanded Remarks

The EditValueChanging event is raised when the edit value (BaseEdit.EditValue) is about to be changed (in code or by an end-user). The potential new value can be identified by the ChangingEventArgs.NewValue parameter. The current edit value is identified by the ChangingEventArgs.OldValue parameter. To cancel the modification, set the Cancel parameter to true.

Note

Do not display modal dialogs or move focus within the EditValueChanging event, as this can lead to the loss of the current value.
