I am trying to run both client and server events when clicking a button.
Since the code i wrote i tried this enclosed code as a test but it won't work please tell me what i'm doing wrong:
(P.S. I posted the browser source as there is almost no code behind and this, i think, shows more details)

else {
theform = document.Form1;
}
theform.__EVENTTARGET.value = eventTarget.split("$").join(":");
theform.__EVENTARGUMENT.value = eventArgument;
theform.submit();
}
// -->

<input language="javascript" onclick="Javascript: return test(); __doPostBack('Button1','')" name="Button1" id="Button1" type="button" style="Z-INDEX: 101; LEFT: 248px; POSITION: absolute; TOP: 120px" value="Button" />

TIA,
GK582Hi,
Can I know how it won't work? Client script not run and server code not run?
The scenario should work, but I can't repro your problem. May I see you sample code? Is it a VS project or just a plain single ASPX page?
Thanks

The following code snippet works for me. If you use code behind model, you need to paste client script into aspx file and move server script code to code behind file
<%@. Page Language="VB" %>
<script runat="server">
Sub Page_Load()
if not Page.ispostback then
button1.attributes.add("onclick", "Javascript: return test();")
end if
end sub
Sub button_click(byval sender as object, byval e as System.EventArgs)
REsponse.write("<h1>post back</h1>")
end sub
</script>
<script language="javascript">
function test() {
alert("hi!");
}
</script>
<html>
<body>
<form id="form1" runat=server>
<asp:button runat=server id=button1 text="button1" name=button1 onclick="button_click"></asp:button>
</form>
</body>
</html>
