Need help converting a C#/.NET method into client-side (javascript) function
Hey Guys,
I have implemented an AJAX Toolkit CalendarExtender. I have a method 'CheckDate' in javascript (followed a tut!) that checks to see if the user selected a date > DateTime.Now().
Well, I have a few other things to check but not sure how to do them in javascript, so I'm hoping someone here can help me. I mean, i can somewhat convert it but it'll be too mangled, I'd rather learn the right way. I'm attaching the code and any help will be appreciated.

how to call server side function from client side javascript?
Hi all, I have a image button in the update panel. I would like to call a method from server side (not from webservice) to get the variable when Onclick on the image button is invoked. Is there any way that I can able to access this function from the client script?
In using the UpdatePanel, in essence, you're already doing this because there will not be a full postback. You can make an asynchronous call to your Click method of your ImageButton. So, what do you want to do with this "variable"?Christopher Reed"The oxen are slow, but the earth is patient."...

Is it possible to call client side function from server side code without initial client request?
Atlas is great. I'm using timer to periodically check database changes on server to populate client side controls with new data. Is it possible to do it without a lot of client requests to server which takes a huge useless network traffic? Server should call client side function on all connected clients when, for example, 'database updated' event occurs on server. Thanks.
