Create checkboxes dynamically

Hello,

I want to create dynamically checkboxes based on sproc result (one checkbox for each row).Here's my code:

public void selectChecks(Label appno, Label Cat)
{
SqlConnection connection = getConnection();
try
{
connection.Open();
SqlCommand command = new SqlCommand("ChecksSelect", connection);
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("@Appno", SqlDbType.Int).Value = Convert.ToInt32(appno.Text);
command.Parameters.Add("@Cat", SqlDbType.Int).Value = Convert.ToInt32(Cat.Text);
SqlDataAdapter adapter = new SqlDataAdapter(command);
DataSet ds = new DataSet();
adapter.Fill(ds);
foreach (DataTable table in ds.Tables)
{
foreach (DataRow dr in table.Rows)
{
CheckBox check = new CheckBox();
check.Text = dr["CheckDescr"].ToString();
if (dr["CheckResult"].ToString() == "1")
check.Checked = true;
else
check.Checked = false;
check.ID = dr["CheckCode"].ToString() + "Lbl";
}
}
}
catch (Exception ex)
{ myMessageBox(ex.Message); }
}

How can I place them in my form's table?

Thank you in advance.

try this
//Drag and drop panal on the Webpage.
//After drag and drop following code will be generated automatically
protected System.Web.UI.WebControls.Panel PnlControl;
//Declare a CheckBox
CheckBox chkList1;
private void Page_Load(object sender, System.EventArgs e)
          {
                .
                .
                //Page load code goes here
                .
                .
          }
#region dyanamic checkboxes
//Function to generate the dyanamic checkboxes
private void AddCheckboxes(string strCheckboxText)
          {
                try
                {
                     if(PnlTimeExpence.HasControls())
                     {
                           return;
                     }
                     for(int intControlIndex=0;intControlIndex=5;intControlIndex++)
                     {
                           chkList1 =new CheckBox();
                           chkList1.Text = strCheckboxText;
                           chkList1.ID="Chk"+intControlIndex;
                           chkList1.Font.Name = "Verdana";
                           chkList1.Font.Size = 9;
                           PnlControl.Controls.Add(chkList1);
                           PnlControl.Controls.Add(new LiteralControl("
"));
                     }
                }
                catch(Exception exp)
                {
                     throw new Exception(exp.Message);
                }
          }

If you are using WebForm then you can use PlaceHolder control. You need to add checkboxes to placeholder control.
foreach (DataRow dr in table.Rows)
{
    CheckBox check = new CheckBox();
    check.Text = dr["CheckDescr"].ToString();
    if (dr["CheckResult"].ToString() == "1")
        check.Checked = true;
    else
        check.Checked = false;

check.ID = dr["CheckCode"].ToString() + "Lbl";
PlaceHolder1.Controls.Add(check);
}
