[解决办法]
datagridview不是winform中的吗？怎么到asp.net区来问？

dgv1.EndEdit();
foreach (DataGridViewRow dgvr in dgv1.Rows)
{
dgvr.Cells["Check"].Value = checkState;
}

Check就是你的列名
[解决办法]
#region 选择CheckBox
DatagridViewCheckBoxHeaderCell cbhCell = new DatagridViewCheckBoxHeaderCell();
cbhCell.OnCheckBoxClicked += new CheckBoxClickedHandler(cbhCell_OnCheckBoxClicked);
DataGridViewCheckBoxColumn cbCheck = new DataGridViewCheckBoxColumn();
cbCheck.HeaderCell = cbhCell;
cbCheck.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
cbCheck.ReadOnly = false;
cbCheck.Name = "Check";
cbCheck.Width = 40;
cbCheck.HeaderCell.Value = string.Empty;
#endregion

private void cbhCell_OnCheckBoxClicked(bool checkState)
{
dgv1.EndEdit();
foreach (DataGridViewRow dgvr in dgv1.Rows)
{
dgvr.Cells["Check"].Value = checkState;
}
}
