Custom Server Control Property

I wrote a simple server control that inherits from the DropDownList
control. I will be using the control in an aspx page and want to
access it in a repeater. I have created a public property called
DefaultValue. For some reason, the property is never set from within
my aspx page. It just gets ignored. Does anyone know why?

Here is how it looks in my aspx:

<frmcontrol:controltypedropdown DefaultValue="5"
id="Controltypedropdown1" runat="server"/>

Below is my control code.

namespace blah.Controls

/// <summary>
/// A server control to display the dropdown of Control Types. Will
/// displayed programatically in a repeater.
/// </summary>
public class ControlTypeDropDown :
private DataTable dt;
private ListItem[] coll;

private string defaultValue="0";
public string DefaultValue
get{return defaultValue;}

public ControlTypeDropDown() : base()
Survey s = new Survey();
dt = s.GetFormControls();
coll = new ListItem[dt.Rows.Count+1];
coll[0] = new ListItem("", "0");
for(int i=0;i<dt.Rows.Count;i++)
coll[i+1] = new ListItem(Convert.ToString(dt.Rows[i]["type"]),

HttpContext.Current.Application.Add("ControlTypeDr opDown", coll);
coll = (ListItem[])HttpContext.Current.Application["ControlTypeDropDown"];

this.Items.FindByValue(DefaultValue).Selected=true ;
