Extjs 4 drag-drop (grid as target panel) ?

[RashmiBhadsawle]

Hi,
I am working on ExtJs 4 (Drag n Drop). I have successfully implemented this link. But is there any way to to get the control over the component before it is dropped to second grid?
I have followed the link here wherein the target panel is a form, and I am getting the control of the component before dropping to the form. How to implement the same for the first link where the target panel is a grid?
I tried comparing the both but get error like : Uncaught TypeError: Cannot read property 'dom' of undefined
Any suggestion?
Thanks in advance!

You will have to post some code for someone to help you... that error is far to generic.

But have you looked at the "beforedrop" event?
