>I wish to create a grid class with methods for setting the index order of data to the column header clicked. I have created the custome method to detect whether an index exists for the control source but cannot see how to place method code in the Column header click event of the class to be inherited by the instance of the grid on the form.
>can any one help ?

two options you have are
create a grid with more columns that you need (i.e. max number of columns you use) and remove column in run-time
the second is to create the class definition for the column, header etc. in code (in a PRG) and add them in run-time
