Public Event CellValidationError As CellValidationErrorEventHandler

Event Data

The event handler receives an argument of type CellValidationErrorEventArgs containing data related to this event. The following CellValidationErrorEventArgs properties provide information specific to this event.

Cell (Inherited from Infragistics.Win.UltraWinTree.CellEventArgs)Returns the UltraTreeNodeCell object for which this instance was created.
Column (Inherited from Infragistics.Win.UltraWinTree.CellEventArgs)Returns the UltraTreeNodeColumn for which this instance was created.
Node (Inherited from Infragistics.Win.UltraWinTree.CellEventArgs)Returns the UltraTreeNode for which this instance was created.
RaiseDataErrorEvent Gets/sets whether the DataError should be raised to report the error to listeners of that event.
RestoreOriginalValue Gets/sets whether the cell's value will be restored to the value it had prior to entering edit mode.
StayInEditMode Gets/sets whether the cell will remain in edit mode, preventing the end user from leaving the cell until a valid value is entered or the edit mode session is canceled.
The following code sample demonstrates how to use the CellValidationError event to apply a default value to a cell when the user enters invalid data:
