Hi,

I have four dropdownlist in one update panel and NthinDiagramControl in an another update panel.
I want to refresh the Image or load a different image on each dropdown_selectedindex change event.
If i remove the update panel the event will have postback and whole page is refreshed rendering the required image. I don't want it to refresh the whole page for rendering the image.
How can i refresh the image inside the update panel without complete postback.

Thanks,
Sudarshan

Hi,

You in order to achive this you should use custom requests. Take a look at the Show/Hide Subtree Decorator example. It demonstrates how to implement the functionality you require.
