I tried and found WebDataSource Control very useful ! Congrats for the same.
I encounter one problem, whenever there Null Value in any field, it gives
following error while opening the table :
Subsystem Call: BASE
System Code: 1111
Default Status: .F.
Description: Argument error
Operation: LEN
Arguments: [ 1] = Type: U Val: NIL
Involved File:
Dos Error Code: 0
Trace Through:
LEN (0)
TWEBRECORDS:GETEDITABLE (169)
TWEBRECORDS:OPEN (89)
TSQLTABLE:OPEN (318)
TFORM1:FORMINITIALIZE (57)
TFORM1:ONINITIALIZE (0)
TFORM1:NEW (195)
MAIN (14)

Oops.....I found it.
Tables without Primary Key were creating problem.
Solved it.
Very happy with this Control.
