{
for (int i = 0; i <this.GridView1.Rows.Count; i++)
{
int id = Convert.ToInt32(this.GridView1.DataKeys[i].Value);
if ((this.GridView1.Rows[i].Cells[0].FindControl("CheckBox1") as CheckBox).Checked == true)
{
Delete(id);
ClientScript.RegisterStartupScript(GetType(),"提示","<script>alert('刪除成功！')</script>");
}
}
this.GridView1.DataBind();
}//刪除
private void Delete(int id)
{
using (SqlConnection conn = new SqlConnection(str))

SqlCommand comm = conn.CreateCommand();
comm.CommandText = "delete from Notice_Msg where id=@id";
comm.Parameters.Add(new SqlParameter("@id", id));
comm.ExecuteNonQuery();
