datatable处理gridview筛选后的值

 DataTable dt = (DataTable)gridView1.GridControl.DataSource;
 DataRow[] drr = dt.Select(gridView1.RowFilter);
 foreach (DataRow dr in drr)
 {
        dr["SelectFlag"] = "";
 }
 gridView1.GridControl.DataSource = dt;
 gridView1.GridControl.Show();

快速全选筛选之后的gridview值。

类似方法也可将datarow[]组装为新的datatable
