how can I write JavaScript code in asp.net in code behind using C#.
For example, I have click button event when I click the button I want to invoke this java script code:
alert("You pressed Me!");
I want to know how to use java script from code behind.
yes client side must be java script but my qustion is not that.i am asking that can i use c# language to implement "actions" fired on "click side events" such as mouse over the reason for this question is that i remember some syntax of registering functions for particular events of formview, which are call when the event occurs (yes there ispostback involved" is something like the above possible for client side events using c# or even vb.net
protected void Page_Load(object sender, EventArgs e)
{
Label3.Text = "this is label three";
Label3.Attributes.Add("OnMouseOver", "testmouseover()");
}
protected void testmouseover()
{
Label4.Text = "this is label 4 mouse is working!!";
}
in my asp.net website, i have textbox control inside datagrid control. I would like to add textchange event in javascript where i need to sum the values inside textboxes in datagrid and show that addition in lable outside grid. I would also like to do same addition in codebehind(*.cs) But codebehind only execute when browser not support javascript. It means when browser support javascript only client side javascript should execute not server side code

How do i update the existing data and it will auto save in my sql database.
I've been assigned changes to make to an ASP.NET project. The WebForm I'm working on needs to dynamically display and hide controls in response to user actions.
So far, so good. My approach would be to create a little JavaScript. However, on this page, the markup is part of a template for a Telerik control (which I know nothing about). I'm not sure the ramifications of this. Can I still use JavaScript for templated markup?
I tried to insert some existing JavaScript in the page. The first problem I have is my use of <%= ControlName.ClientID %>, which produces an error because the name of the control in the template is not seen to exist by ASP.NET.
Is there another way to do this, or am I just going to run into more problems?

I know how to write/create cookies in JavaScript.
//Create the cookies
document.cookie = "Name=" + Name + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Surname=" + Surname + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Number=" + Number + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Email=" + Email + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Country=" + Country + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Company=" + Company + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
document.cookie = "Title=" + Job + ";expires=Friday, 31-Dec-2011 12:00:00 GMT; path=/";
But how can I read each one of them in JavaScript because I want to populate the text boxes next time the user come to the form? I have tried this but it does not work:
var cookieName = ReadCookie("Name");
document.getElementById('txtName').value = cookieName;
Edit with Answer:
I used this code.
<script type="text/javascript">
function getCookie(c_name)
{
if (document.cookie.length>0)
{
c_start=document.cookie.indexOf(c_name + "=");
if (c_start!=-1)
{
c_start=c_start + c_name.length+1;
c_end=document.cookie.indexOf(";",c_start);
if (c_end==-1) c_end=document.cookie.length;
return unescape(document.cookie.substring(c_start,c_end));
}
}
return "";
}
function checkCookie()
{
Name = getCookie('Name');
Surname = getCookie('Surname');
Email = getCookie('Email');
Company = getCookie('Company');
Title = getCookie('Title');
if (Email!=null && Email!="")
{
//Populate the text boxes.
document.FormName.txtName.value = Name;
document.FormName.txtSurname.value = Surname;
document.FormName.txtEmail.value = Email;
document.FormName.txtCompany.value = Company;
document.FormName.txtjob.value = Title;
}
}
</script>
And called the checkCookie() function like so from the window.onload
<SCRIPT TYPE='text/javascript' LANGUAGE='JavaScript'><!-- //
window.onload = initPage;
function initPage()
{
checkCookie();
}

View 8 RepliesI have started learning MVC and I have few questions in my mind,
1: As I seen that there is no .cs file in View, then how would I write my code behind for the page. I am very new to inline coding, do I need to learn it ??
2: What if I want to develop pages like I have already done for asp.net 2.0/3.5 websitepreviously.
Though I have gone through some articles regarding MVC and MVP, I am not able to take decision to write code with MVP or MVC pattern?
Which pattern will allow us to write loosely coupled code? Can I assume Asp.Net web forms is MVP by default?

Since everyone yells at me that MessageBox doesn't work when the project is uploaded to the server, I need to migrate to javascript alert box. As I was changing my MessageBoxes, I tested and found that they weren't being produced. I'm not sure if it matters, but they are in a try/catch block, which is shown here:[Code]....
This all worked before when I had MessageBox - it showed, then the page redirected when I clicked Ok.
I either don't understand how try/catch works, the javascript isn't adding, or Response.Redirect is executed before I can see the alert box and click Ok on it.
(just as a note, everything works fine, but the alert box doesn't show)........if I add the (javascript) code before the try block, the alert box comes up, so it's not something wrong with the writing of the javascript or executing it at least (I think).
I have a textbox on my aspx page defined as:
<input name= tbdisplay type="text">
I can pick the data (I built a touch screen keyboard and I used javascript to write to the thextbox) from code behind using:
string textdisplaydata = this.Request.Form.Get("tbdisplay");
But I can't figure out the way to write back to the same display from code behind. In other words, I need to send a message back to the textbox from code behind. Because I did not defined the tbdisplay to runat="server", I can't see the control tbdisplay. Also, I can't run the tbdisplay at server because the keyboard doesn't work.
