#Declaration

C#
VB.NET

public class TreeListCellValidationEventArgs :
    TreeListNodeValidationEventArgs,
    IDataCellEventArgs

The TreeListView.ValidateCell event receives TreeListCellValidationEventArgs as an event handler argument.

#Remarks

The TreeListView.ValidateCell event occurs before the focused cell's modified value is posted to a data source, allowing manual validation of its new value.

The focused cell's new value is returned by the ValidationEventArgs.Value property. Its previously valid value is returned by the TreeListCellValidationEventArgs.CellValue property. To indicate that the new value is invalid, set the ValidationEventArgs.IsValid property to false.
