Will calling .click() fire an updatepanel Trigger?

This might seem a bit silly but...

Basically, I have a javascript function which calls the .click() method of a button, this button resides outside of any UpdatePanels

This button is also set as a trigger for one of my UpdatePanel controls.

My problem is, the button click runs fine, the server side click event fires ok and rebinds some data for a GridView which is inside the UpdatePanel, but the UpdatePanel does not update its contents.

Do you have to physically click the button with your mouse to cause the Trigger? Or should the programmatic javascript call to click() work?

No will not cause it trigger, you need a postback for that, not a javascript call


You cantrigger an UpdatePanel refresh from the client side, using __doPostBack().

Hi

The programmatic javascript call to click() should work, you must do something wrong.

Look this sample:

xmlhttp and outside servers.

I'm sure this is some kind of security feature but I'm hoping there is a fix or work around.

I have a page that is doing a xmlhttp GET to an outside server to get some data back. This works 100% when I am in debug mode in vs2008. Soon as I move the application to 1 of 2 hosting sites, it no longer works. I just get "access denied"

Why does this work just fine locally but not else where? Is there a way to around this some how?

For cross server requests, you'll need to either have an external service that supports JSONP (which is honestly kind of a pain to deal with) or create a proxy service on your local server that acts as a middle man.


but why does it work on my local server, which is a basic IIS setup and not on another server?


Different browser security settings for that local server probably.


:(

Guess I'm out of luck. I'll just run the part that needs to do the request from my local machine and everything else from the hosting.

Unless anyone has any tricks up their sleeve that can make this work :)

Thanks again ASP.Net forum people


You're not out of luck.

You just need to create a web service proxy that's running on your local domain. Basically an asmx in your solution that basically does no more than call the remote service and then return that result. So, your client side functionality can call the remote service by calling the local one, and there are no cross domain issues.
