Server Side code withoout page refresh

Is it possible if I can call server side code without the page
refreshing?

Thanks,

SeanShort answer : no, if it's a postback.
On the first call, yes, of course.

yes. the techinque is call AJAX. google for toolkits. also asp.net 2.0 has a
very simple (feature wise) implementation for IE.

Yes.
You can use Remote Scripting callbacks (often now referred to as "AJAX").
This normally involves using XmlHttp from the client - side page DOM to make
a call into the server-side page and call a method on it, returning the
results as either javascript, JSON, or HTML which is used to update the DOM
at the client.

The new Atlas Framework does this for ASP.NET 2.0. You could also look at
Anthem.Net and MagicAJax.net over on Sourceforge.net if you are interested in
using a whole "framework" for this type of operation.

Here you can find a comparison of AJAX frameworks, that allow page
updates with AJAX without reloading the whole page:

Some frameworks allow roundtrips with ASP.NET server events without
updating any page content.

Sure, although you're still posting back...just not the whole page.

server side kepress event on textbox

HI There,
I have a webform and I am wanting to call a function from a textbox control
located on the webform when a key is pressed. Can this be done in server sid
e.
already know do like this
on ASPX page within javascript tags
<script laguage=javascript>
function trapKeypress() {
alert (window.event.keyCode);
}
</script>
and in .vb page of the .aspx page ..'
textbox1.attributes.item("onkeypress") = "javascript:trapKeypress();"
Can I do it without using JavaScript .
RegardsYou can submit the form in trapKeypress(). This will cause a postback and
you can pass to the server a sort of info telling what exactly caused the
postback. This will resemble a server event. You can't avoid using
javascript on the client side. How can server know what is happening in the
browser?

Server was unable to process request. --> Array cannot be null...

Hello,
I am trying to call a simple web service from .net environment. The service
gets an array parameter. When I run it, it becomes the error:
Server was unable to process request. --> Array cannot be null. Parameter
name: bytes
I am sure that my array is not null. Besides, its name isn't "bytes".
What is wrong with it?
Regards..Have you tried using the debugger to step through the code and see
where the exception occurs? Did the error message include a stack
trace with line numbers? Something is null when it shouldn't be,
you'll have to find it.

Try to build with debugging information included and get a stack trace
with line numbers. Or try putting some trace statements inside. A
little more information makes tracking down the source of the
information easier. Once you have some information you can review the
code and see what could be going wrong.
