I have 2 webforms. The first one Webform1.aspx collects the data entered by the user and post it to the second form Webform2.asp. The second form has 3 textboxes , once the user enters the data in the first webform , the values should be passed to the second form so that each textbox will hold the value the user entered from the first form.
I tried it with for the second form, but im getting

Message 1 Validation (ASP.Net): Attribute 'value' is not a valid attribute of element 'TextBox'.
MSDN TextBox Class
Long story short the <asp:TextBox /> tag doesn't have a value attribute. That is why when you try to put it on the tag, the aspx engine gets all in a tizzy.
Edit:
It does have a Text Property, which you can see more about here.
This shouldn't be caused by your cross page posting, but if still have problems there please ask another question.

I try to save the changed text of an editable div. I put some text on page load into the div and change it in the browser, but I can't save the changes because the innerHTML content doesn't change.
This is my aspx file:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Title</title>
</head>
<body>
<form id="form1" runat="server">
<div contenteditable="true" runat="server" id="txtText" ></div>
<asp:Button ID="btnSave" runat="server" Text="Speichern" OnClick="btnSave_Click" />
</form>
</body>
</html>
This is the code behind file:
public partial class editWordModule : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
txtText.InnerHTML = "This is the unmodified text";
}
protected void btnSave_Click(object sender, EventArgs e)
{
string test = txtText.InnerHtml;
//still shows "This is the unmodified text" while it was changed before in the div
}
}
}
So how do I save the edited innerHTML of the div?
Make a little trick with JavaScript.
When the button is clicked, get the innerHTML of DIV and put into a asp:HiddenField
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Title</title>
</head>
<body>
<script type="text/javascript">
function ChangeDiv() {
var div = document.getElementById("txtText");
var hdn = document.getElementById("hdnText");
hdn.value = div.innerHTML;
}
</script>
<form id="form1" runat="server">
<div contenteditable="true" id="txtText"></div>
<asp:HiddenField ID="hdnText" runat="server" ClientIDMode="Static" />
<asp:Button ID="btnSave" runat="server" Text="Speichern" OnClick="btnSave_Click" OnClientClick="ChangeDiv()" />
</form>
</body>
</html>
And in your code behind read the hidden field.
string hdn = hdnText.Value
I have the following code to submit a form with a hidden value.
The problem is - I can't set the value of MyNewValue before the form is submitted to the remote address https://some-remote-site/Form.aspx.
Does anybody know how I can set the hidden value when the user clicks the button and then submit the form to the same address?

<asp:HiddenField id="MyNewValue" Value="X" runat="server" />
<p>
<label for="Username">Username:</label>
<asp:TextBox id="Username" Text="Username" runat="server" />
</p>
<asp:Button ID="SubmitForm" runat="server" onclick="SubmitForm_Click" Text="Button" />
</fieldset>
</form>
</body>
MyFile.aspx.cs
// Not executed because action="https://some-remote-site/Form.aspx" is set
protected void SubmitForm_Click(object sender, EventArgs e)
{
MyNewValue.Value = DateTime.Now.ToString();
}
You can do it client-side using jQuery. So when the user clicks submit, and before submitting the form, you can update your hidden input and then return true to proceed the submission of your form.
This is it could be done:
$(document).ready(function(){
$('#myForm').on('submit', function(){
$('#MyNewValue').val('YOUR_VALUE');
return true;
})
});
I'm new to C# - ASP.NET and I'm trying to drop data ,from a filled form, from .aspx to .cshtml.
I made a form with three TextBoxes and a Button, a method for the "onClick". This method set the value of ViewData (name,date,user) with the values of the three TextBoxes. And I want to collect these value on the page targeted by the form.
I do not get any error but ViewData(name,date,user) seems to be empty.
Here's my code :
CSHTML
#{
ViewBag.Title = "Consulter";
}
#Html.Partial("MenuBar")
#Html.Partial("Connexion")
#ViewData["name"]
<style type="text/css">
...
</style>
...
<h2>...
ASPX
<%# Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" %>
<script language="C#" runat="server">
public void Ajouter(Object sender, EventArgs e)
{
ViewData["name"] = dateForm.Text;
ViewData["date"] = dateForm.Text;
ViewData["user"] = userForm.Text;
}
</script>
<!DOCTYPE html>
<html>
<head id="Head1" runat="server">
<meta name="viewport" content="width=device-width" />
<title>AjouterForm</title>
</head>
<body>
<h1>Ajouter un produit</h1>
<div>
<form id="form1" runat="server" action="Consulter" defaultbutton="bouton1" method="get">
<div>
<asp:TextBox placeholder="Name" runat="server" ID="nameForm"/></br>
<asp:TextBox placeholder="Date" runat="server" ID="dateForm"/></br>
<asp:TextBox placeholder="User" runat="server" ID="userForm"/></br>
<asp:Button runat="server" text="Envoyer" ID="bouton1" onClick="Ajouter"/>
<asp:Label runat="server" ID="label1" />
</div>
</form>
</div>
</body>
</html>
If you know how to solve it or if you have another way to do it, it would be amazing :)
Thank you in advance.
I am using jQuery to set some values in hidden fields, which are being set perfectly.
But the problem is hidden fields don't show me the values until I submit the form.
Is there away to get at the values before the form is submitted.
<script language="JavaScript" src="http://j.maxmind.com/app/geoip.js"></script>
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#hdnCountryCode").val(geoip_country_code());
$("#hdnCountyName").val(geoip_country_name());
$("#hdnCity").val(geoip_city());
$("#hdnRegionCode").val(geoip_region());
$("#hdnRegion").val(geoip_region_name());
$("#hdnLatitude").val(geoip_latitude());
$("#hdnLongitude").val(geoip_longitude());
});
</script>
<body>
<form id="form1" runat="server">
<asp:HiddenField runat="server" ID="hdnCountryCode" />
<asp:HiddenField runat="server" ID="hdnCountyName" />
<asp:HiddenField runat="server" ID="hdnCity" />
<asp:HiddenField runat="server" ID="hdnRegionCode" />
<asp:HiddenField runat="server" ID="hdnRegion" />
<asp:HiddenField runat="server" ID="hdnLatitude" />
<asp:HiddenField runat="server" ID="hdnLongitude" />
<asp:Button runat="server" ID="btnV" Text="s" onclick="btnV_Click" />
<%
Google.Values Send = new Google.Values();
Send.CountryName = hdnCountyName.Value;
Send.CountryCode = hdnCountryCode.Value;
Send.RegionName = hdnRegion.Value;
Send.RegionCode = hdnRegionCode.Value;
Send.City = hdnCity.Value;
Send.Latitude = hdnLatitude.Value;
Send.Longitude = hdnLongitude.Value;
%>
</form>
</body>
With the code above the values of the hidden fields when passing to the properties of my class is giving me "". But when I use button click event same code returns me all the values which i need
To get the values you need to get the rendered id, and this is done like:
$("#<%=hdnCountryCode.ClientID%>").val(geoip_country_code());
You can see this code:
<head>
<title>Test</title>
<script language="JavaScript" src="http://j.maxmind.com/app/geoip.js"></script>
<script language="JavaScript" src="http://code.jquery.com/jquery-1.8.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function () {
var countryCode = geoip_country_code();
var countryName = geoip_country_name();
$('#countryCode').html(countryCode);
$('#countryName').html(countryName);
});
</script>
</head>
<body>
<p>
CountryCode: <span id="countryCode">countryCode</span>
<p>
<p>
CountyName: <span id="countryName">CountyName</span>
<p>
</form>
</body>
</html>
I need value to be passing from ASP.NET page to JavaScript and then to HTML textfield.
My following code is able to read values from ASP.NET to JavaScript but unable to pass value form JavaScript to HTML TextField. Can anybody please correct my code.
Default.aspx
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<head id="Head1" runat="server">
<title></title>
<script type="text/javascript">
function can() {
var myVariable = '<%=ServerSideVariable %>';
document.write(myVariable);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<br />
<br />
<br />
<br />
<br />
<input id="Text1" type="text" value='can()'/>
</div>
</form>
</body>
</html>
Default.aspx.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{
public string ServerSideVariable { get; set; }
protected void Page_Load(object sender, EventArgs e)
{
string pval = "Passed value;
ServerSideVariable = pval;
}
}
document.getElementById('Text1').value = myVariable;
But you need to move the assignment script block bellow the declaration of element Text1, or do it on document.ready
Anyway, you also need to error check.
It's best to use JQuery anyway, and get familiar with it.
As others have said with javascript OR like this:
(since there is nothing in your example that requires javascript -- KISS-- don't use javascript if you don't have to do so.)
<%# Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<head id="Head1" runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<br />
<br />
<br />
<br />
<br />
<input id="Text1" type="text" ><%=ServerSideVariable %></input>
</div>
</form>
</body>
</html>
Do this instead in a document.load.
document.getElementByID('Text1').value = myVariable;
