PropertyListBox.CellValue
From Jeremie Leroy - XOJO Controls Wiki
Method
PropertyListBox.CellValue ( PropertyName As String, RaiseCellValueChanged As Boolean = False, Assigns Value As String )
Assigns the Value to the Property found by its name. The PropertyName is considered as an object. If you want to assign a value to a parameter but several Properties share the same name under different headers then refer to the Property as: HeaderName.PropertyName
If the Property wasn't found then it will search through each Property and assign the value even if it is a header. RaiseCellValueChanged is optional. If True, the CellValueChanged event will fire after assigning the Value.
