Calling jvascript function from the button under UpdatePanel

Hello,

I am having a a web application developed using asp.net2.0 with vb.net as a language.

In this web application i am having two buttons and one update panel. Now my button1 is outside the updatepanel and another button2 is present inside the updatepanel.

In asp.net if we want to run any javascript function on the click of a button then we normally use the button.attribute.add() function but if we want that when user click on button then first some server side code will be performed and then the javascript function will be called.

For that we uses the below code in asp.net !!!

Page.ClientScript.RegisterClientScriptBlock(Me.GetType,"Script", "<Script>alert('Hello');</Script>")

this code is working fine on the click event of the button that is present outside the update panel. But when i am running the same code on the click event of the button that is present inside the updatepanel then its not working,

Remeber that i d't want to run the javascript code when user just click on the button , i want first some server side code wil perform his work then after this script will run.

But for controls under update panel its not working.??

please paste your code here, because I am doing almost the same thing here without any issues.

Hi,

Add a Literal control to your web form.

In your Click method use this code:

literal1.Text = "<script type=\"text/javascript\"> alert('Hello world!');</script>";

Dont forget to clear Text property in another postbacks.

Use ScriptManager.RegisterStartupScript, instead of the ClientScript class' method.

Can anyone tell me the solution for this?

Me too getting the same issue.

Thanks,

Jasmeeta.

Calling a JS function from server side

Hi,

I try to call a javascript function from the server side but it doesn't work, here my code :

1<%@dotnet.itags.org. Page Language="C#" AutoEventWireup="true" CodeFile="test.aspx.cs" Inherits="test" %>23<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">45<html xmlns="http://www.w3.org/1999/xhtml" >6<head runat="server">7 <title>Test</title>8</head>9<body>10 <form id="form1" runat="server">1112 <atlas:ScriptManager ID="scriptManager1" runat="server" EnablePartialRendering="true"></atlas:ScriptManager>1314 <atlas:UpdatePanel ID="UpdatePanel1" runat="server">15 <ContentTemplate>1617 <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />18 <asp:TextBox ID="TextBox2" runat="server" Text="test"></asp:TextBox><br />19 <asp:Button ID="Button1" runat="server" Text="Write" OnClick="Button1_Click" />20 <asp:Button ID="Button2" runat="server" Text="Clear" OnClick="Button2_Click" />2122 </ContentTemplate>23 <Triggers>24 <atlas:ControlEventTrigger ControlID="Button1" EventName="Click" />25 <atlas:ControlEventTrigger ControlID="Button2" EventName="Click" />26 <atlas:ControlValueTrigger ControlID="TextBox1" PropertyName="Text" />27 </Triggers>28 </atlas:UpdatePanel>2930 </form>31</body>32</html>33

And the code behind :

1using System;2using System.Data;3using System.Configuration;4using System.Collections;5using System.Web;6using System.Web.Security;7using System.Web.UI;8using System.Web.UI.WebControls;9using System.Web.UI.WebControls.WebParts;10using System.Web.UI.HtmlControls;1112public partialclass test : System.Web.UI.Page13{14protected void Page_Load(object sender, EventArgs e)15 {1617 }1819public void Button1_Click(object sender, EventArgs e)20 {21 TextBox1.Text ="Button clicked";22 }2324public void Button2_Click(object sender, EventArgs e)25 {26 TextBox1.Text ="";27 Response.Write("<script type=\"text/javascript\">alert('hello');</script>");28 }2930}31

When i click on the button 2, my alert function is not called and the textbox 1 is not cleaned.

How can i call the JS function ?

call webservce

i try to call a webservice when form load,but i can't

my code like

function callServicce()

{..........}

</script>

</form>

please help me ??

thank you

You need to register your webservice using ScriptManager and ServiceReference.
Here are examples of the webservice and javascript code which calls the webservice. Method DoSearch is calling the webservice method

Webservice in (Webservice.asmx)

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
[ScriptService] //If this is not added, then it is not possible to generate javascript proxy.
public class MyWebService : System.Web.Services.WebService {

[WebMethod]
public string HelloWorld(string query)
{
string inputString = Server.HtmlEncode(query);
if (!String.IsNullOrEmpty(inputString))
{
return String.Format("Hello, you queried for {0}. The "
+ "current time is {1}", inputString, DateTime.Now);
}
else
{
return "The query string was null or empty";
}

}

}

JavaScript snippet:

<form id="Form1" runat="server">
<asp:ScriptManager runat="server" ID="scriptManager">
<Services>
<asp:ServiceReference path="~/WebService.asmx" />
</Services>
</asp:ScriptManager>
<div>
Search for
<input id="SearchKey" type="text" />
<input id="SearchButton" type="button" value="Search"
onclick="DoSearch()" />
</div>
</form>
<hr style="width: 300px" />
<div>
<span id="Results"></span>
</div>

<script type="text/javascript">

function DoSearch()
{
var SrchElem = document.getElementById("SearchKey");
MyWebService.HelloWorld(SrchElem.value, OnRequestComplete);
}

function OnRequestComplete(result)
{
var RsltElem = document.getElementById("Results");
RsltElem.innerHTML = result;
}

</script>

Hope this helps

thanks for your reply

but my question is how to call webservice on formload event ?

i already do what you show,but webservice could'n to be call on form load event

Ajax, your code looks fine. Perhaps you could post your entire script so we can debug further?
I think you could try ScriptManager1.RegisterClientScriptBlock method in Page_Load Event.

CalendarExtender: internationalization

Hi!

How canI personalizzate extender for using italian (o other) language?

Thank you.

Have you tried the latest version of the toolkit? The calendar string "Today" is now localized in 14 languages including Italian. All toolkit controls now support localization. On how to achieve that check out the Calendar control source code and the localization entry on theOther Neat Stuff page.
Thanks for the answer.
