I have a website that uses a frameset which consist of a left frame and right frame. The right frame consists of the main contents, which are selectable via a set of iframes. The left frame has a graphical panel that users interact with to request info from or send data to the main content frame. Once each iframes is selected, that iframe loads its own panel so the user can use the features of that iframe and panels.
The problem that I have here is that every time a selection is made on the panel, it causes the main content to go through a full postback which cause the pages to flicker and at the same time cause the left panel to refresh as well hence looses the previous selection.
What I would like to know is how and what can I do eliminate the flickers while maintaining the view state of the graphical panel. I have heard of the Microsoft ICallbackEvenHandler but I don’t know how to use it and I don’t know if it would be the right tool for the job.
Please would someone point me in the right direction.
