I am writing a program that adds images to the web page at runtime
by using the following commands

(Namespace : System.Web.UI.Page)

HtmlImage h=new HtmlImage();
h.Attributes.Add("style","position:absolute; left:150; top:200");
h.Src="bb/00000.jpg";
this.Controls.Add(h);

When the user clicks on the image i added i want to redirect the page to www.x.com

I have written the function below to handle this event, but i need to add an event handler to
the image "h" so that the function is executed

private void h_Click(object sender, System.EventArgs e)
{
 Response.Redirect("www.x.com");
}

this.Events.AddHandler(...............);

Please Can you tell me exactly what parameters to pass to the above procedure

Thanx.

Got a better idea:

HtmlImage h = new HtmlImage();
h.Attributes.Add("style","position:absolute; left:150; top:200");
h.ATtributes.Add("onclick", "javascript:window.location.href=\"http://www.x.com\";");
h.Src="bb/00000.jpg";
this.Controls.Add(h);

This will accomplish exactly the same thing, unless you need to something else before calling Response.Redirect().

To capture events, you should use the asp WebControls instead of the HtmlControls.

Try using an ImageButton, which has an OnClick event.



(Also, a side note, avoid setting the style attribute explicitly.  You can use the Style property of the control instead to add name/value paris of styles to the controls style collection.  Even better, use css classes, so you don't need to recompile your code just to change the style of an image.)
