Question

Hi,
I have one DataGridView in my WindowsForm Application and it consists of one column with CheckBoxes.Here I am using Paging for my DataGrid.Whenever I want to check some records from first page and some records from next page to delete.When I go to next page the previous page checked records will be unchecked.
How to maintain the CheckBox state as checked?
Thanks in advance...
