Create event handler for componenent that's created programaticall

[mg]

The code below creates an ImageButton when a LinkButton is clicked.

How can I create an event handler for this ImageButton which can't be seen
in Design?
private void LinkButton1_Click(object sender, System.EventArgs e)
{
System.Web.UI.WebControls.ImageButton ImageButton1 = new ImageButton();
ImageButton1.Height = 18;
ImageButton1.Width = 100;
ImageButton1.ImageUrl = @"\images\continue.gif";
Panel1.Controls.Add(ImageButton1);
}

Hi,

Use ImageButtton1.[EventName] += new EventHandler ([eventhandler])

Do you want to hook up an existing method or create a new one at runtime?

At this point, I'm not sure.

I'd very much appreciate your providing the code for both cases, including
the code for the eventhandler itself.

I'm still confused about how this all works.

this.ImageButton1.Click += new System.EventHandler(this.ImageButton1_Click);

resulted in the following error message:

'Page' does not contain a definition for 'ImageButton1'

I then rewrote the line as follows:

ImageButton1.Click += new System.EventHandler(ImageButton1_Click);

This code resulted in the following error message:

ImageButton1_Click(object sender, System.Web.UI.ImageClickEventArgs e)
does not match delegate 'void System.EventHandler(object, System.EventArgs)'

Sorry, I pasted wrong code. Here is the correct one:
ImageButton btn = new ImageButton ();
btn.Click += new ImageClickEventHandler(btn_Click);

and the handler:

private void btn_Click(object sender, ImageClickEventArgs e)

The following code ran without error, but the alert did not appear. Can you
see the problem?

private void LinkButton1_Click(object sender, System.EventArgs e)
{
System.Web.UI.WebControls.ImageButton ImageButton1 = new ImageButton();
ImageButton1.Height = 18;
ImageButton1.Width = 100;
ImageButton1.ImageUrl = @"\images\continue.gif";
Panel1.Controls.Add(ImageButton1);
ImageButton1.Click += new ImageClickEventHandler(ImageButton1_Click);
}

private void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
Response.Write("<script language='javascript'>alert('TEST');</script>");
}
