Thanks for your response..
In all these examples, we are using another aspx page (WebForm2.aspx) to show the image. Is there any way we can render the image on WebForm1.aspx without using another page? Because I have some 20 webpages in my application and I have to show grapphs on atleast 15 of them. I don't wat to create another 15 pages just for the grapths. Also I figured out a way where I can just have one webForm for all the 15 graphs. But here I have to pass the chart object to the graph page everytime I want to render the graph.
I'm just wondering if there is any other efficient way to do what I need in my application.
