Thanks venkat for your quick reply. Example scenario is labelfunction of a datagrid takes two parameters - data and column. But datatipFunction takes only one parameter. If we make the second paramter of labelFunction taking befault value null for second parameter like - labelfunction(data:Object, column:DataGridColumn = null) then we can use this labelfunction for assigning to datatipFunction also along with assigning it to labelFunction. In an application suppose we have not used this type of labelfunction for datatipFunction instead we have used a function with only parameter like - mydatatipfunction(data:Object). Suppose I override the itemToDataTip method of DataGridColumn class to pass the column data for scenarios where labelfunction is used for datatipFunction. How to identify a mydatatipfunction is used or labelfunction is used? So I thought of checking for number of parameters the function takes. Hope its clear now. Let me know if you need any other details.
