Answer 1

Well a little bit adding more (i know its very old topic, but still it helps someone)...

I tried

EnableColumnVirtualization="True" VirtualizingPanel.VirtualizationMode="Recycling"
EnableRowVirtualization="True" 

for DataGrid(AutoGenerateColumns="True") binding to DataTable.DefaultView() and No effect on speed, it was still horrible for Speed as well as for navigation between rows. Than, I came up with solution to set Fixed Height and Width of DataGrid. Additionally I also set

RowHeight="23" 
ScrollViewer.HorizontalScrollBarVisibility="Visible"
ScrollViewer.VerticalScrollBarVisibility="Visible"

This makes my page fill very fast... Instead of 2 min, now it takes hardly 10-12 seconds.

Hope it helps someone.

Note: I am using .Net 4.5
