I know this question is asked before, and I looked it up, and found this sulotion:
Page.ClientScript.RegisterStartupScript(this.GetType(), "click", "test();", true);
so I put that in my c# method, and the following javascript code in my head.
<script type ="text/javascript">
function test() {
alert("succes");
}
</script>
this is my html where i call the code behind method.
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div id="ampwirecalc">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" RenderMode="Inline">
<ContentTemplate>
<asp:DropDownList ID="dropdownsize" OnSelectedIndexChanged="wirecalc" onchange="runscalc()" AutoPostBack="true" runat="server">
<asp:ListItem Text="Select Wire Size" value="-1"/>
<asp:ListItem Text="1/0 gauge" Value="0" />
<asp:ListItem Text="4 gauge" Value="1" />
<asp:ListItem Text="8 gauge" Value="2" />
</asp:DropDownList>
<script type="text/javascript">
function runscalc()
{
var totalRMS = document.getElementById('<%=tbx_anw3.ClientID%>').value;
document.getElementById('<%=HiddenField1.ClientID%>').value = totalRMS;
}
</script>
<!--These are the texts giving information on the options-->
<div class="textwirecalc">
<p class="selectedwire">Selected Wire:</p>
<p class="neededruns">Needed Runs:</p>
<p class="selectedsize">Selected size:</p>
</div>
<!--These are the labels that wil show the calculated info-->
<div class="labelwirecalc">
<asp:Label ID="wiretype" runat="server" Text="Wire type will show here"></asp:Label>
<asp:Label ID="wireruns" runat="server" Text="Needed runs will show here"></asp:Label>
<asp:Label ID="wiresize" runat="server" Text="Wire size will show here"></asp:Label>
</div>
</ContentTemplate>
</asp:UpdatePanel>
does anyone know what I'm doing wrong, and what I should do instead.
thanks in advance.
Try this
Page.ClientScript.RegisterStartupScript(this.GetType(), "click", "test();", false);
Reference
last parameter true/false indicate- whether to add script tags.
you can give the javascript like below, no need to write javascript function
Page.ClientScript.RegisterStartupScript(this.GetType(), "click","alert('succes');", true);
UPDATE
ScriptManager.RegisterStartupScript(UpdatePanel1, UpdatePanel1.GetType(),
"click", "alert('succes');", true);
The third parameter must be enclosed with script tags as the
http://msdn.microsoft.com/en-us/library/asz8zsxy.aspx says.

this is a script of switchmenu
On page 1st load it is working good but on doing linkbutton clicking which is inside,
than after script does not get work again.
If I understood your problem, this should solve it:
Javascript
$(function () {
$(".box .h_title").not(this).next("ul").hide("normal");
$(".box .h_title").not(this).next("#home").show("normal");
});
function lbClicked(obj) {
$(obj).next("ul").slideToggle();
}
ASP.NET
<asp:LinkButton ID="lnk" runat="server" onclick="lnk_Click" onclientclick="lbClicked(this)"><%# Eval("subtitle") %></asp:LinkButton>
C#
protected void Page_Load(object sender, EventArgs e)
{
// You don't need the line below, which is wrong anyway
//ScriptManager.RegisterStartupScript(this, this.GetType(), "javascript", "function();", true);
}
protected void lnk_Click(object sender, EventArgs e)
{
// You don't need the line below, which is wrong anyway
//ScriptManager.RegisterStartupScript(this, this.GetType(), "javascript", "function();", true);
}
I know that this question has been asked before, but none of the remedies seem to be my solution.
I have an aspx page and a code behind with a Page_Load routine. My routine writes a record to a SQL table to capture the user's credentials.
The Page_Load has a !IsPostBack check, aspx has AutoEventWireup="True", and I have no img or any other element that would cause an AutoPostback to my knowledge. Still Page_Load is called twice.
Here is my .aspx page and the code behind. I am hoping someone can help.

The visible function doesnt work, but why? Is a true set in a callback not allowed?. When I set the visible to true on top of the page(_Default : System.Web.UI.Page) it is working.
information_remedyID.Visible = true;
information_remedyID.Text = inquiryId;
TOP Class:
public partial class _Default : System.Web.UI.Page

XDocument doc = XDocument.Parse(responseXML);
inquiryId = (string)doc.Root.Element("inquiry_id");

Do you use a UpdatePanel with UpdateMode="Conditional"

In case you use WPF
information_remedyID.Visibility = Visibility.Visible;
Sorry, overread ASP!
if (inquiryId == null | inquiryId == "")
If this should be an or change it to a double stripe:
if (inquiryId == null || inquiryId == "")

And in your code, after you changed the visibility:
MyUpdatePanel.Update();
I couldn't get this to work either.
A workaround is to use Style="display: none;" instead of Visible="False". Then you can reveal it with
information_remedyID.Style["display"] = "initial";

Why My Accordion remove?
It's because your accordion is inside of an updatepanel. When you post back, everything inside your updatepanel is removed from the DOM and readded. Hence, the DOM element that was the accordion is gone. You need to call: $("#accordion").accordion(); after your postback.
one way you could do that is to do this:
<script type="text/javascript" language="javascript">
function SetupAccordion(){
$("#accordion").accordion();
}
$(document).ready(function () {
SetupAccordion();
if (typeof Sys.WebForms != 'undefined') {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(SetupAccordion);
}
});

function pageLoad() {

var hfd = $get('<%= HiddenField1.ClientID %>');
var oldSetActiveTab = Function.createDelegate(tabContainer, tabContainer.set_activeTab);
tabContainer.set_activeTab = function (value) {
if (value.get_id() == '<%= Panel3.ClientID %>' && hfd.value != "-1") {
alert("oops");
}
else {
oldSetActiveTab(value);
}
};
}
