Dynamically generating imagebutton control

[krish]

hi,

I am dynamically generating Imagebutton (say 5 imagebutton, in loop) .

for each imagebutton url , i am dynamically generating image and
assigining to it.

every thing is ok upto this stage.

The problem arises when i click on particular image button
i want to know which image button is clicked, in click event and take
appropriate actions.

i have saved image like
bmp.Save(Response.OutputStream,
System.Drawing.Imaging.ImageFormat.Gif);
