            lblship.Text = (CInt(lblsubtotal.Text) * 0.15).ToString("c")
            lblgrand.Text = (CInt(lblsubtotal.Text.ToString) + (lbltax.Text.ToString) + (lblship.Text.ToString)).ToString("c")


end sub

I dont see where you are facilitating the deletion of items from your cart.

Here is the psuedo code for what i would do

Handle OnItemDeleted
--Remove indexed item from the cart
--Calcualte the new total in SQL
--Rebind the grid

That is just what i would do. In any case what i think your poblem is is that when you delete an item, you are still working with the grid that has that item in its cells, even though you have removed it from the backend table. You should delete from your database rebind your grid then loop through for your new total.
