ajax - asp.net page wait others server side / asynchrone page -

-

i created asp.net page waiting ajax. have 1 page creating takes 30 seconds. on every step change session value.

i have page ajax, returning session value showing percentage of creation. but, dont know why, ajax page awaits end of creation of first page. 100% @ end.

maybe it's because use vs development server , not iis server. if problem, can change settings of development server asynchrone execution?

or else?

webforms not ideal asynchronous operations.

add signalr project , use hub push status data page update current state of process running asynchronously.

an example of technique perform type of asynchronous notification covered in blog post titled "a guide using asp.net signalr radnotifications"
