Binding dataset to listview

[Bom]

Hi,

I bound a dataset to a listview (I used example of Lothka).
I have also a button delete. When I select a row in the
listview and I push delete-button I can delete the row in
the dataset as follows :
ds.Tables[0].Rows[Convert.ToInt32(item.Index)].delete().
And then I rebind my listview to the dataset.

But working with item.index is not right.
1. When I am deleting then the 3 row. In the dataset he
deleted the 2e row.

So : listviewItem.index and the index for the rows of the
dataset doesn't match anymore after my first delete.

Same problem when I sort the listview, then there is no
match between both indexes.

What is the best way to resolve that problem?
Thanks
Bom
