Try This


private void ListView(DataSet _DataSet)
{
DataTable dtable = _DataSet.Tables["table_name"];
listView1.Items.Clear();
for (int i = 0; i < dtable.Rows.Count; i++)
{
DataRow drow = dtable.Rows[i];
if (drow.RowState != DataRowState.Deleted)
{
ListViewItem lvi = new ListViewItem(drow["column1"].ToString());
lvi.SubItems.Add (drow["column2"].ToString());
lvi.SubItems.Add (drow["column3"].ToString());
lvi.SubItems.Add (drow["column4"].ToString());
listView1.Items.Add(lvi);
}
}
}
