Hi Tracy
Finally I would be able to retrieve labels but sorry I used labelFunction
because for some reason labelfield is breaking other programmer's code: I
have no idea why.
So Below is my code. But Now I am doing some logical error. I am getting all
the values in an array but it gives all the entries in all the whole list.
For example if there are 10 values named friendly name I need the list to
show
Value 1
Value 2
Value 3
.
.
.
.
Value10 as 10 entries in the list but with my code it is showing
Value1,Value2....Value10 10times in 10 rows with 10 entries in each row 10
times . I guess I am messing up in the logic. Can you please help me to fix
this problem.
Thanks alot for all your help
