I have a C# component that basically implements Javascript Rollovers. It
has been working great. I decided that I would add the option to have it
displayed as normally img tags or through an ImageButton (ie <input>
tag). I needed to use an image button for something I was doing because of
the postback. This is a .cs file therefore there is no interface. In the
code, I have create an Image button and set all of the properties and added
it to the page. That works and everything. Now the question is, how do I
get the Click event from the ImageButton to become part of my class. I was
reading something in the Help files about Bubbling Events, but it didn't
make a whole lot of sense. Just as a note, I found this C# file online
when I was first starting this project. I am not a C# programmer but a
VB.NET programmer though I do understand enough C# to get by.

This is inside of CreateChildControls()
ImageButton btn = new ImageButton();
btn.ID = ID;
btn.CommandName = CommandName;
btn.ImageUrl = this.ImageUrl;
btn.Width = Convert.ToInt16(this.imgWidth );
btn.Height = Convert.ToInt16(this.imgHeight) ;
this.Controls.Add ( btn );
// there is a little extra javascript attributes
in there too

I have tried do
public event ImageClickEventHanlder Click;

then tying it to btn.Click += this.Click but I couldn't get it to
work. Let me know if you need any more code.

Thanks,
Jonathan

I solved my problem. I thought it wasn't finding it because it wasn't
showing up in IntelliSense, but it's working now.
