How to get controls from panel in asp.net c#?
Well, I am doing a project on online movie ticket booking.
My problem is, I want to show the seating arrangement in a screen of a particular theater.
As in every row the number of seats can vary so what I have done is add a panel and in it a checkboxlist is dynamically added during runtime.
each checkboxlist represents a single row.
string s;
for (int i = 0; i < ds.Tables["row_id_no_of_seats"].Rows.Count; i++)
{
cbl = new CheckBoxList();
cbl.RepeatDirection = 0; //horizontal
cbl.RepeatLayout = 0; //table
cbl.RepeatColumns = (int)ds.Tables["row_id_no_of_seats"].Rows[i].ItemArray[1];
Panel1.Controls.Add(cbl);
for(int j=1;j<=(int)ds.Tables["row_id_no_of_seats"].Rows[i].ItemArray[1];j++)
{
s = ds.Tables["row_id_no_of_seats"].Rows[i].ItemArray[0].ToString() + j.ToString(); //ex:A+1
cbl.Items.Add(s);
string query1 = "select booking_detail.row_id,booking_detail.column_id from booking_detail,booking where (booking_detail.booking_id=booking.booking_id) and (booking_detail.booking_date='" + bk_date + "') and (booking.booking_date='" + bk_date + "') and (booking.theatre_id=" + theatre_id + ") and (booking.screen_id=" + screen_id + ") and (booking.movie_id=" + movie_id + ") and (booking.show_start_time='" + show_start_time + "') and (booking.class_id=" + class_id + ")";
SqlCommand command1 = new SqlCommand(query1, connection);
adapter.SelectCommand = command1;
adapter.Fill(ds, "seat_booked_info");
// it checks and disables the seats which have been pre- booked.
for (int k = 0; k < ds.Tables["seat_booked_info"].Rows.Count;k++) {
if(ds.Tables["seat_booked_info"].Rows[k].ItemArray[0].ToString().Equals(ds.Tables["row_id_no_of_seats"].Rows[i].ItemArray[0].ToString())) && (ds.Tables["seat_booked_info"].Rows[k].ItemArray[1].ToString().Equals(j.ToString())))
{
cbl.Items.FindByText(s).Selected=true;
cbl.Items.FindByText(s).Enabled = false;
}
}
ds.Tables["seat_booked_info"].Clear();
}
}
Now what I want is, how do I get the details of the checkbox which have been selected by the user as the checkboxlist are dynamically added to the panel?
你会使用这样的东西：
foreach (Control c in Panel1.Controls)
{
CheckBoxList list = c as CheckBoxList;
if (c != null)
{
// Do something with the list
}
}
