Well you could always copy the list of selected rows into a temp
collection and then delete all the rows in that collection.

Hi Richard,

Based on my understanding, you want to delete several selected rows fromt
the datagrid at one time.

Yes, because of databinding, deleting one row in underlying datasource will
make DataGrid repopulates itself, and all the rows' row number behind the
deleting row will decrease one.

For this issue, I think we may use a ArrayList to store all the initial
selected row number, when deleting the row, each row number decrease the
already deleted row count. Sample code like this:

private void button1_Click(object sender, System.EventArgs e)
{
    ArrayList al=new ArrayList();
    CurrencyManager cm
=(CurrencyManager)dataGrid1.BindingContext[this.ds.Tables["your table"]];
    for(int i=0;i<cm.Count;i++)
    {
        if(this.dataGrid1.IsSelected(i))
        {
            al.Add(i);
        }
    }

    for(int i=0;i<al.Count;i++)
    {
        int row=(int)al[i];
        this.ds.Tables["your table"].Rows.RemoveAt(row-i);        //row number
decrease already deleted row count
    }
}
