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"] = "1";
}
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
