Strange problem of Dynamic Checkbox

[savvy]

I'm comparing two strings and trying to check a dynamic checkbox when
its true on pageload , but i dont know why i'm not able to do that on
page load, when i click some other links and come back to this page
then the required checkbox will be checked. I'm not able to figure out
where is the problem. Sorry about the long code
Any help will be greatly appreciated

private void Page_Load(objec t sender, System.EventArg s e)
{
if(!IsPostBack)
{
get_servc();
}
}
override protected void OnInit(EventArg s e)
{
InitializeCompo nent();
base.OnInit(e);
if (Page.IsPostBac k)
{
Session.Timeout =120;
_checkboxes = (ArrayList) Session["CheckBoxAr ray"];
}
else
{
_checkboxes = new ArrayList();
get_servc();
}

foreach(CheckBo x c1 in _checkboxes)
Panel1.Controls .Add(c1);
}
public void get_servc()
{
strcatgy = Convert.ToStrin g(Session["Category"]);
string temp = strcatgy;
int xPos = 20;
int yPos= 335;
int count=0;
objcmd = new SqlCommand("Sel ectDynControls" , objConn);
objcmd.CommandT ype = CommandType.Sto redProcedure;
objConn.Open();
objRdr=objcmd.E xecuteReader();
while(objRdr.Re ad())
{
CheckBox c1 = new CheckBox();
c1.ID="chk" + _checkboxes.Cou nt.ToString();
c1.AutoPostBack =true;
c1.Visible=true ;
c1.Text = Convert.ToStrin g(objRdr["CbName"]);
if(c1.Text == temp)
{
c1.Checked=true ; // this is the part which is not working
}

c1.Style.Add("D ISPLAY", "BLOCK");
if((count % 6)==0)
{
yPos +=30;
xPos =20;
}
c1.Style.Add("P OSITION", "absolute") ;
c1.Style.Add("T OP", Convert.ToStrin g(yPos));
c1.Style.Add("L EFT", Convert.ToStrin g(xPos));
_checkboxes.Add (c1);
Panel1.Controls .Add(c1);
xPos += 120;
count += 1;
}
objRdr.Close();
objConn.Close() ;
yPos = yPos + 50;
xPos = 275;
}

Actually the code had no problem
As I was creating the dynamic controls prior to page load. we have to
call method get_servc() again as shown in my code below
and now its working
hope this will be of some help to the people who stuck with the same
problem
private void dl_Edit(object source,
System.Web.UI.W ebControls.Data ListCommandEven tArgs e)
{
strcatgy =((Label)e.Item .FindControl("l blcategory")).T ext;
Session["Category"]= strcatgy;
get_servc();
............
...........

}
