Calling a Server function from an HtmlInputHidden Control

Hey experts,

I want to have a functionality like the following:

<input id="hdnValue" type="hidden" runat="server" onpropertychange="fun1()">

If fun1 is a client javascript function, the syntax above would be true, but I want fun1 as a server function to be called according to the above case.

In order to do that you will need to create a custom control. That overrides the PostBack event. As custom controls are fairly involved I cannot post an entire section of code here. If you would like an explanation then please let me know.

Hi,

you could use the ServerChange event on server side
and on the client catch the onpropertychange - event with javascript and submit the form

server

this.hdnValue.ServerChange += new EventHandler(hdnValue_ServerChange);


client

function fun1() {

    window.Form1.submit();
}

this will postback the page and if the value of hdnValue has changed since the last postback
hdnValue_ServerChange() will be called.


Hope that helps,

Thalox

Hi mte01,

you can do that by using ServerChange event of the HtmlInputHidden control
when the page is submitted this event will fires if the value within the hidden filed has changed
this event will be rezied after the Page_Load event
