Declaration
Event Data
The EditValueChanging event's data class is ChangingEventArgs. The following properties provide information specific to this event:
| Property | Description |
|---|---|
| Cancel | Gets or sets a value indicating whether the event should be canceled. Inherited from CancelEventArgs. |
| IsBoundUpdatingEditValue | For internal use. |
| IsTextChanging | For internal use. |
| NewValue | Gets or sets the value which is about to be assigned to the editor. Setting the NewValue property is not supported if the editor uses masked input (RepositoryItemTextEdit.Mask). |
| OldValue | Gets the editor’s value. |
Remarks
The EditValueChanging event is raised when the edit value (BaseEdit.EditValue) is about to be changed (in code or by a 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.
