Datagrid and deletebutton

What I wonder is if anyone know if it´s possible to trigger any code Before the row dissapreres.
I know how to trigger code when the key is pressed etc. But all that code comes after the row is gone in the datagrid.

Example:
I want to delete the last row in the datagrid and want to know what rowindex that row got.
All I get is the index of the row before.

How should I know if the row that was delteted was the last or the one before?

In RowDeletion procedure add one single line before other commands :

OldRowIndex=Me.DataGrid1.CurrentRowIndex

'Here OldRowIndex is module level integer variable

Thanks.
But where do I find the function before rowdeletion?
I have tried to read the row when the key is pressed down but it never enter the function.
why I don´t know.

write in procedure in which you are deleting row (before row-deletion code)

deletebutton takes away the post in the datagrid before I can do anything.

But no probs. I have solved it. Just reloaded the datagrid from the dataset and some checks etc...

Thanks for responding parminder
