Hi dilipkumarmdk,
There's sample in this
KB article , and the Rubber band selection is accomplished using managed code. You still need to write code to draw control rectangle outside those controls were selected.
The code is using C#.NET language, if you have difficulty in understanding them, you can translate them using
online translating tools .
If you have problem with this, please feel free to let me know.
Best regards,
Bruce Zhou
