UserControl Problem

[suicidaltendencies]

Here is my problem. I'm putting 3 user controls on my page. In my page load function I'm specifying the visiblity of the user controls. 2 invisible and 1 visible. In the visible control there are buttons. I want the the other controls to be visible if the buttons are pressed. How do I detect the button was clicked on the visible usercontrol? What code should I write in my page?

Thanks,
Harold

Page section:
<pm:usercontrol id="usercontrol" runat="server" />
<pm:usercontrol id="Usercontrol1" runat="server" />
<pm:usercontrol id="Usercontrol2" runat="server" />


CodeBehind section:
private void Page_Load(object sender, System.EventArgs e)
{
Control usercontrol = Page.FindControl("usercontrol"
Control Usercontrol1 = Page.FindControl("Usercontrol1"
Control Usercontrol2 = Page.FindControl("Usercontrol2"

if(!Page.IsPostBack)
{
usercontrol.Visible=true;
Usercontrol1.Visible=false;
Usercontrol2 .Visible=false;
}
}

The code to make the other two controls visible should be written in the Button Click event handler in the "visible" control code behind, not on the container page:

private void Button1_Click(object sender, System.EventArgs e)
{
  Parent.FindControl("Usercontrol1").Visible = true;
  Parent.FindControl("Usercontrol2").Visible = true;
}

Can I somehow write this code in the Parent page code behind section?

You can create a custom event handler in your ascx and wire it up to a handler in your aspx like this.

//In ASCX

public event System.EventHandler MyEvent;

private void Button1_Click(object sender, System.EventArgs e){
  MyEvent(sender, e);
}

//In ASPX

private void InitializeComponent(){
  this.Load += new System.EventHandler(this.Page_Load);
  this.UserControl1.MyEvent += new System.EventHandler(this.MyEvent_Event);
}

public void MyEvent_Event(object sender, System.EventArgs e){
  //Show the buttons
}

You can use this technique to create and "bubble" (though its not strictly event bubbling) events from ascx and custom server controls.
