Thanks for your reply.
Yes, I am using itemsource of Datagrid for items. I dont want to give data in slots. I want to display without slots.

Now queries are:
1) If visibility dont stop the control to draw. Is there any property to do the same?
2) Can you provide any link for data virtualtion so that I can show only numbers of rows which are visible and load another row when user scolls.
