Create your event handler as follows. Make sure you set the accessibility
to protected as shown.

protected void ImageButtonClick(object sender,
System.Web.UI.ImageClickEventArgs e)

{

Response.Write("the image was clicked");

}

Then, in the aspx file, add this attribute within your <ASP:IMAGEBUTTON >
tag:

    ONCLICK="ImageButtonClick"
