DataGridView row added event

Question

Hi all, I'm using a DataGridView and I bind a List to the DataSource.

I already have the right columns and I map exactly the fields. What I'm trying to do is handling a sort of RowAdded or RowDataBound (like in aspx GridView) event.

The only event that I found is RowsAdded but no matter how many items I have, it is fired only 4 times the first time i bound, and twice the other times, with values

e.RowCount:1 e.RowIndex:0 e.RowCount:[n-1] e.RowIndex:1 *where n is the number of my items

is there a way I can get to a handle for each item?

EDIT: without changing the DataSource = binding method

I just ran into this same issue. You can get the index and range of the rows that were added from the event args passed to the RowsAdded event handler. Use this information to loop through each of the added rows. e.RowIndex and e.RowCount will let you determine the added rows.

private void DataGridView1_RowsAdded(object sender, System.Windows.Forms.DataGridViewRowsAddedEventArgs e)
{
    for (int index = e.RowIndex; index <= e.RowIndex + e.RowCount - 1; index++) {
        DataGridViewRow row = DataGridView1.Rows(index);

        // Do something with the added row here
        // Raise a custom RowAdded event if you want that passes individual rows.
    }
}

If you wanted you could inherit datagridview and make your own grid that throws a "RowAdded" event inside the loop above.
