Calling a function on the server and returning a value

[Ed Staffin]

Hi,
It seems like this should be possible, but I'm not seeing any examples.
All I want to do is, in javascript on teh client side make a call somehting like:

var myReturnValue = SomeCallToTheServer(SomeArgument);

Where SomeCallToTheSever is a server side function something like:

Public Function SomeCallToTheServer(arg as Object) as Int32
    return SomeValue
End Function

Any guidance and pointers to an example would be fantastic.
Thanks ... Ed

Hi Ed,

Try the below suggestion:

<script type="text/javascript">
function MyClientFunction()
{
    var myReturnValue = "<%= SomeCallToTheServer(arguments) %>";
}
</script>

You also might need to wrap the sclient script in a RadCodeBlock.

I hope this helps you.

Hi,
Thanks for the reply, but I don't think that will work. In your example, the arguments parameter is the problem. I need to pass a parameter from the client.
Thanks ... Ed

Hi Ed,

Yes, you are right. But tell me what do you need to pass as an argument and how would be this used on the server?

Thanks,

Hi,

I have a situation where I have an Id on the client and I want ot look up a name to go iwth it so I want to pass the id to the server and get the name back.
Thanks ... Ed

HI,

hmm... I understand your idea but I am not sure how this could be done.
What comes into my mind is to use hidden field, e.g. set the ID to the hidden field on the client and use its value on the server.
