please help

my create function is

private void createcontrols()
{
 
i = 1;
 
//if (CheckBoxListmst.SelectedIndex > -1)
 
//{
 
foreach (ListItem li in CheckBoxListmst.Items)
{
 
if (li.Selected == true)
{
 
Label label = new Label();
 
DropDownList dropdownlist = new DropDownList();
 
label.ID = "label" + i.ToString();
 
label.EnableViewState = true; 
 
dropdownlist.ID = "dropdownlist" + i.ToString();
 
dropdownlist.EnableViewState = true ;
 
 
label.Text = li.Text;
 
//Label1.Text += dropdownlist.ID ;
 
i++;
 
//rdr = cmd.ExecuteReader();
 
for (int j = 0; j < 5; j++ )
{
 
ListItem ld = new ListItem();
 
ld.Text = j.ToString() ;
 
ld.Value = j.ToString();
 
dropdownlist.Items.Add(ld);
 
}
 
PlaceHolder1.Controls.Add(label);
 
PlaceHolder1.Controls.Add(dropdownlist);
 
 
 
Response.Write("<br>");
 
 
}
 
}
 
}
 
// }
 
}
 
 

and i access it with the code as

Label objlbl;
 
DropDownList objdrop;
 
objlbl = this.PlaceHolder1.FindControl("label1") as Label;
 
objdrop = this.PlaceHolder1.FindControl("dropdownlist1") as DropDownList;
 
if ((objlbl != null) && (objdrop.SelectedIndex > -1 ))
 
{
 
Label1.Text = objlbl.Text; //Page.FindControl("label1").ToString() ;
 
Label2.Text = objdrop.SelectedValue;
 
}
 
 

i call createcontrol funtion in filterbutton_cl ick and override oninit()
