Found this thread already hence posting my queries here.( Users feedback that we got as well) -
We have an ASP.Net application heavily based on RADControls. What we observed is
1. If the page kept idle for some duration(15-20 min) and then tried to do any action related to RadControls (RadCalnder, RadDateTime, RadGrid click events etc) , Page takes longer time to refresh than usual...almost 45 sec on an avg. Whereas during continuous operations it gets loaded within 15 sec.
2. Also, on every internal postback within UpdatePanel, the page takes longer time to refresh in order to load new state.
Any suggestions that you can think of ? We tried capturing the Network traffic but with no avail as nly .aspx request and WebResourceHandler request seems to take long time.
Appreciate an experts opinion on this?
