public event BaseContainerValidateEditorEventHandler ValidatingEditor
Public Event ValidatingEditor As BaseContainerValidateEditorEventHandler
The ValidatingEditor event's data class is BaseContainerValidateEditorEventArgs. The following properties provide information specific to this event:
|ErrorText||Gets or sets the error description.|
|Valid||Gets or sets whether the value is valid.|
|Value||Gets or sets the value being validated.|
Editor validation takes place when attempting to save the edit value (using the PivotGridControl.PostEditor method) or when closing the active editor. First, automatic validation is performed. The editor determines whether it can accept the entered value. After automatic validation has been performed, the ValidatingEditor event is raised. Handle this event to implement custom constraints on cell values.
If the entered value is returned by the event parameter’s Value property. If it is invalid, set the Valid property to false. In this instance, the edit value is not saved, and the cell remains focused so that an end-user can correct it.
The default event handling result (displaying an error icon and tooltip leaving editor focus unchanged) can be overridden within the PivotGridControl.InvalidValueException event handler.
