Couldn't create parent property with child properties expanded by plus sign...

[Guest]

Hell
I have a Web Custom Control project in ASP.NET. I'm using a subclassing technique to add functionality in HyperLink web

server control. I want to create a property "BrowserWindow" of my class "NewWinHyperLink" which will contain child

properties. When I use this custom control in testing web application these child properties don't appear with 'plus sign' in

visual studio designer. I want to make my parent property to have plus sign in order to expand in VS designer and adjust its

child properties (e.g. look at any web server contol and notice the Font property which have plus sign
here is my sample code where I want to make BrowserWindow property appears with plus sign

namespace CustomContro

[ToolboxData("<{0}:NewWinHyperLink runat=server></{0}:NewWinHyperLink>")
public class NewWinHyperLink : System.Web.UI.WebControls.HyperLin

protected override void OnInit(EventArgs e

base.Text = this.ID
NavigateUrl = "#"
// Do whatever the control usually does OnIni
base.OnInit(e)


private BrowserWindowInfo bwi = new BrowserWindowInfo()

[Browsable(true)
Bindable(true)
Category("Design")
public BrowserWindowInfo BrowserWindow //doesn't appear with plus sign

ge

return bwi

se

bwi = value





public class BrowserWindowInf

// String settings: default is blank
private string m_strURL = "about:blank"
// Integer settings: 0 invoked default
private int m_Height = 0
private int m_Width = 0


[Browsable(true)
Bindable(true)
Category("Appearance")
public string UR

ge

return m_strURL

se

m_strURL = value



[Browsable(true)
Bindable(true)
Category("Appearance")
public int Heigh

ge

return m_Height

se

m_Height = value



[Browsable(true)
Bindable(true)
Category("Appearance")
public int Widt

ge

return m_Width

se

m_Width = value






Can anyone please give me some hint? Do u think if I miss any attribute only

Thanx
