usercontrol and checkbox event

[seal]

OK, I am trying to fire an event from a usercontrol that tells the page when
a checkbox was clicked.

Here is the control and when I try and wire up the page to catch the event,
my event is not shown. What am I doind wrong?

public delegate void CheckBoxEventHa ndler(object sender, System.EventArg s e);

public class WebUserControl1 : System.Web.UI.U serControl
{
protected System.Web.UI.W ebControls.Chec kBox CheckBox1;

private void Page_Load(objec t sender, System.EventArg s e)
{
// Put user code to initialize the page here
Response.Write( "WebUserControl 1 :: Page_Load <BR>");
}

#region Web Form Designer generated code
override protected void OnInit(EventArg s e)
{
//
// CODEGEN: This call is required by the ASP.NET Web Form Designer.
//
InitializeCompo nent();
base.OnInit(e);
}

/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeCompo nent()
{
this.CheckBox1. CheckedChanged += new
System.EventHan dler(this.Check Box1_CheckedCha nged);
this.Load += new System.EventHan dler(this.Page_ Load);

}
#endregion

public event CheckBoxEventHa ndler CheckedMe;

protected void OnCheckedMe(obj ect sender, System.EventArg s e)
{
if(CheckedMe != null)
{
CheckedMe(this, e);
}
}
private void CheckBox1_Check edChanged(objec t sender, System.EventArg s e)
{
Response.Write( "WebUserControl 1 :: Begin CheckBox1_Click <BR>");
OnCheckedMe(thi s,e);
Response.Write( "WebUserControl 1 :: End CheckBox1_Click <BR>");
}

If you are using ASP.NET 1.1 The page that uses the control has to
1- Register the control, e.g.
<%@ Register TagPrefix="cc" tagName="c1" src="WebUserCon trol1.ascx" %>

2- declare it in the codebehind as protected, e.g.
protected WebUserControl1 CheckBox1;

Then you will be able to write:
CheckBox1.Check edMe+=new CheckBoxEventHa ndler(CheckBox1 _CheckedMe);

Phillip thank you for your input.

I think I found the problem and confusion on my part.
I have 1.
<%@ Register TagPrefix="uc1" TagName="WebUse rControl1"
Src="Control/WebUserControl1 .ascx" %>

<uc1:webusercon trol1 id="WebUserCont rol11"
runat="server"> </uc1:webusercont rol1>

But for your 2nd point I have
protected UserControl WebUserControl1 1;

I think this is where the problem may be, point 2 that is. By using this I
never see the event CheckedMe. This is a UserControl, so am I declaring it
incorrect on my page?

Yes, when you used the base type "UserContro l", intellisense could not
display for you the methods in your derived control, which inherited the base
type.

Ok, I am not usnderstanding something or I have been looking at it too long.
I have dragged the control on my webform and
I declare the control....
protected UserControl ThisControl;

I try and create an event, though intellesense does not see it. OK, I can
live with that but I would think it would be easier to see the event I am
looking for...
this.ThisContro l.CheckedMe += new CheckBoxEventHa ndler(ThisContr ol_CheckMe);

Compile error--
does not contain a definition for 'CheckedMe'??

So I can clearly see that there is a definition for the CheckedMe in my
control (public event CheckBoxEventHa ndler CheckedMe;)

So what am I doing wrong?

These are basic concepts in Object Oriented Programming.

An object of type System.Web.UI.U serControl (the base type) does not define
an event named "CheckedMe" . Any object even if it were derived from
UserControl but cast as the base type cannot consume that event and hence the
compiler error.
