JQuery Dialog

JQuery Dialog

Hi All,

I am new to using Jquery. I want to open a dialog using jquery and when the dialog shows , it should make a call to some aspx page to update its own contents.

I know an updatepanel can be contained in a <div> and can be opened as dialog using Jquery and after opening up of dialog can issue any command like pressing a button to update dialog's contents from server.

But i want to make a call to aspx page as soon as it shows up , without issuing any command from dialog itself.

Is there any event in PageRequestManger or anything else to achieve this ?
In my current project, popups are shown using RAD controls and IFRAME which contains the actual aspx page.I want to replace all these kinds of popups using jquery.

Thanks

Dhruv
