Please post your code in a standalone testcase that implements EntryPoint. Stacktraces with linenumbers are meaningless without posting the versionnumber you use.

YOu probably are not using any loader in your liststore, which is required.

Hi Sven,
Thanks for ur quick reply. we are able to display records on the widget now. the problem is what is the default visible record size of LivegridView. i have total of 404 records. by default only 17 are visible, on scroll we get 17 more etc. plz help me how can i increase the default display size. i have attached the screen shot of my widget. after 17 records still we have space on widget, how can we utilize all space. plz find and suggest me.

Thanks!
