A challange with client callback (2.0)
-
Hi guys, I have implemented a simple client callback functionality (which works fine), that upon clicking an html button only a portion of the page accesses database and changes a field. Then within the same javascript I have a timer go off and once 90 seconds elapses, it changes the properties of certain fields/controls on the page. Now, my challange is to access the database again once the 90 seconds has passed and change a couple of the data fields... I cannot think about a way to do this! Can somebody PLEASE PLEASE PLEASE help me? :-) Nila Fridley

Hi there, IMHO, you can use the
setTimeout/setIntervalmethods to implement the client side timer, then once after a specified period of time, a custom client side function is called and you can use it to update the DB with ClientCallback. You can easily find the exampples of these two functions out there. -

I was hoping to be able to do yet another callback for that purpose(you know, like going through RaiseCallbackEvent and GetCallbackResult again). But in order to do that I had to wire that particular javascript to a specific control's Attribute collection (this.someControl.Attributes.Add("", "")... Would you happen to know of a good article or two that may shed some light? Thank you so much :-) Nila Fridley

Turns out I had to provide yet another callbackEventReference (with a function named Release(arg, context)) that would tell my server to do something, and I called that function from within the timer function... long story short, it worked and Im super happy :-D Nila Fridley
