BorderThickness="1,0,1,1"

Source="{Binding AllRoutesItemSource}"

DisplayMode="All"/>

When User make choice of Column & Filter and after this when user Delete the Row My Grid Data go Off & pagination shows only Page 1. this happens specially in case when After filter on 1 row is available.
Later after a while when Click on Filtered Column Again I see all the values in it. If I select I m able to see data in grid but Paginaiton still have page 1 only.
I've more then 20000 rows for this grid.

How to resolve this issue ?
