I have a small websolution that needs the user to input a password. I have two input boxes
<input type="password" runat="server" id="m_txtPassword1"/>
If I set some chars to the Value-property of the control like this:
m_txtPassword1.Value="someChars";
The password box is rendered empty. No bullets are shown. If I look into the rendered html-source, also no value-tag has been rendered. If I change the type to
<input type="text" runat="server" id="m_txtPassword1"/>
the chars are shown. Is this by design? How can I disable this feature?
Please note, I don't want to put a real password into the value-property, I only want to show the user that there is already a password set, and this is IMO done best with some 8 bullets in the input-control. But for this, I need the possibility to set the value-property of the control.
Update
For all, having the same problem: I have tried to declare <asp:textbox id="m_txtPassword1" runat="server" TextMode="Password" /> with the same result. Also m_txtPassword1.Attributes["value"]="someChars" has not helped.
It seems that this is realy not possible.
As a workaround, I declared the password-boxes as plain html without the runat="server" and have set the value-property in markup (via two properties from the code-behind). Not nice but I really want to show the user that he has already entered a password.
Another workaround would be to set the value through javascript on load.
This is by default. You cannot set a password.
I make this works,
<html>
<head>
<script type="text/javascript">
function alertValue()
{
alert(document.getElementById("password1").value);
}
function setpassword()
{
password1.value="someChars";
}
</script>
</head>
<body>
<form>
<input type="password" id="password1" value="" />
<input type="button" id="button1" onclick="alertValue()" value="Show default value" />
<input type="button" id="button2" onclick="setpassword()" value="Set value" />
</form>
</body>
</html>
Try this:
http://jsbin.com/ocexo5
It is by design, for security reasons - so that the password is not in the
HTML in plain text.
Now, you could write out javascript to set the value property of the textbox
on the client, of course this would still mean that you have the password in
plain text in the HTML.
Here is example of the page:
Markup:
<script type="text/javascript">
function setPwd()
{
var Pwd = "<%=Pwd %>";
var txtText = document.getElementById("MainContent_txtText");
txtText.value = Pwd;
}
</script>
<input type="password" id="txtText" runat="server"/>
And code-behind:
public partial class _Default : System.Web.UI.Page
{
public string Pwd;
protected void Page_Load(object sender, EventArgs e)
{
Pwd = "password";
ClientScript.RegisterStartupScript( this.GetType(),"somescript","setPwd();",true);
}
}
Textbox11.Attributes.Add("Value",whatever_your_password_is)

I have a search textbox that I tried wrapping in a form element:
<form id="searchForm" method="GET" action="Search.aspx">
<input name="term" type="text" id="searchTerm" class="nav-search" size="30" />
<input type="submit" value="submit" style="display:none;"/>
</form>
I can't get it to redirect to the content page (Search.aspx) with the query string (term) from the Master Page.
I tried wrapping it in an ASP:Panel and using the DefaultButton Property but that wouldn't call the Click event in code behind.
I'm perplexed as I've searched for a solution for hours and this seems like a such common task. Thanks.
Change your code to this
<input name="term" type="text" id="searchTerm" runat="server" class="nav-search" size="30" />
<asp:Button ID="searchsubmit" OnClick="searchsubmit_Click" runat="server" Text="Search" />
in Site.Master.cs add something like this
protected void searchsubmit_Click(object sender, EventArgs e)
{
Response.Redirect("~/search.apsx?content=" + searchTerm.text);
}
This will allow to search with button click, if you want to hide it, add also panel around first code, saying that this is a button to automatically press when enter is pressed Something like this:
<asp:Panel ID="UserPanel" runat="server" DefaultButton="searchsubmit">
i have a system that generates unique numbers for reference..here is my function in jquery:
function random() {
return Math.floor(Math.random() * 100000000);
}
function generateRandomNumber() {
$("#GenerateCode").val(random());
}
window.onload = function () {
generateRandomNumber();
}
here is my mark up(asp):
<div id="step3" class="formwiz">
<h4>Step 3: Reference Number</h4>
<br clear="all" />
<p>
<label>Reference Number</label>
<span class="field">
<input type="text" id="GenerateCode" name="GenerateCode" class="smallinput" disabled="disabled" /> <small style="color: red">Please write the numbers at the back of your check</small>
</span>
</p>
</div>
this function works fine with html (input)...but when i shifted from input to ast textbox, the numbers are not posted in the textbox...do i need to use getelementbyid.?
please help...
Try using a class instead so change the class attribute to:
class="smallinput random"
and change the javascript to:
$(".random").val(random());
I would take a wild guess that you're actually using ASP.NET and not classic ASP and you try to change the text box to:
<asp:TextBox id="GenerateCode" runat="server" CssClass="smallinput" Enabled="False" />
In such case, the generated ID might be different than what you give it, if the textbox is part of control, placeholder or something like this.
To ensure same ID use ClientIDMode and set it to Static:
<asp:TextBox id="GenerateCode" runat="server" ClientIDMode="Static" CssClass="smallinput" Enabled="False" />
Now the jQuery code should work fine again.
I'm really new to ASP and have a project where I need to capture the login of the person logged into Sharepoint. I have created the following code and am able to get the login. I am having trouble pass the parameter to a form. What is the best way to do this: I know the 2nd part the POST is wrong, I don't know what to do here. Thanks for your help. Scott

You can pass values from the codebehind to html page using for example hidden values, see here.
Usually though values are placed into form elements in the codebehind directly. If the element has the "runat=server" attribute then you can access the element in the Page_Load method using c# and just set the text value directly.
myuserid.Text =
I just wanna ask if there's a possibility to change:
<input type="hidden" name="reference" value="ABC"/>
into this:
<input type="hidden" name="reference" value="any values I want"/>
where I can set any values behind .cs/C# - making it dynamically. The payment gateway I'm using requires and I can't find a way to included an ASP.NET control ( ?)
and I'm needing your suggestions/comments about it. Thanks.
PS. <asp:HiddenField ID="reference" runat="server" Value="ABC" /> is not working because the payment gateway specifically needs the 'name' property.
I know this is an old post, but for anyone looking to solve this issue now - If you add runat="server" to the input, the name will be changed (e.g. MainContentArea_ctl00_ctl01_ctl01_amount). ClientIdMode="Static" will only help for the ID.
To get around this:
In your html page use a Literal :
<asp:Literal runat="server" ID="litInputAmount"></asp:Literal>
In the code behind file, assign a string to the Text attribute of the Literal This string should be the html as you would like it to be. The correct value can also be added for the value field:
litInputAmount.Text = String.Concat("<input id='inputAmount' type='hidden' name='amount' value='", Price.ToString(), "'>");
This will then be compiled as:
<input id="inputAmount" type="hidden" value="224.4" name="amount">
This will give the information to the payment gateway with the correct name, but your value can be managed dynamically. Repeat for any other values that need to be added before sending.
You can just put runat="server" on the control to access it from your code behind:
<input type="hidden" name="reference" id="reference" runat="server" />
Then, in your code behind:
void Page_Load(object sender, EventArgs e)
{
// ...
reference.Attriutes["value"] = "any values I want";
// ...
}
Note that in this case, the "id" attribute is required because when you have runat="server", the id attribute is used to specify the name of the generated variable.
You can use standard input of type hidden as if you are working with static HTML or Razor, and rely on the <%= expression, which is evaluated at render time rather on DataBind() time as the <%# expressions would.
This way, you can have a normal html, for which you can have ASP.NET WebFroms generate the hidden input's value for you server side, without actually having to mark the input with runat="server" or using <asp:HiddenInput control. See the example below, which should do the job:
<input type="hidden" id="add-to-wishlist-url" value='<%= YourServerSideExpressionHere.Execute() %>' />
Of course, this approach is not one size fits all, but seems like the closest to the meet the requirement described 7 years ago...
//<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
protected string GetVariableValue(string AspxPage, string inputTagName)
{
ra migirad
string RegPattern = string.Format("(?<=({0}\".value.\")).*(?=\"./>)", inputTagName);
Regex regex = new Regex(RegPattern, RegexOptions.IgnoreCase);
Match match = regex.Match(AspxPage);
if (string.IsNullOrEmpty(match.Value))
{
RegPattern = string.Format("<input[^>]*{0}[^>]*value=\"([^\"]*)\"", inputTagName);
regex = new Regex(RegPattern, RegexOptions.IgnoreCase);
match = regex.Match(AspxPage);
return match.Groups[1].Value;
}
return match.Value;
}
Apply the parameter:
ClientIDMode="Static"
For example:
<asp:HiddenField ID="reference" runat="server" Value="ABC" ClientIDMode="Static" />
with this, the "ID" with maintain exactly as "reference".
I'm trying to figure out a way to create a page that can be used for generic forms. What i had in mind was someone here at our office would use the obout edit to create html that would look like a form. This html would be saved to a database. When the user wanted to fill out the form and mail it, they would click on the correct form retrieval and this html would be put into a label control. So now the page has a label control on it with some html as the text of the label. The user could type in the values that they wanted. So the html might look something like this:
<p style="margin: 0px; text-align: center;">
Quarterly Report of Employees Serverd</p>
<br />
<br />
Employee:
<input type="text" style="width: 300px; height: 22px;" />
<br />
<br />
Address:
<input type="text" style="width: 300px; height: 22px;" />
<br />
<br />
<br />
The user would type in the input type="text" a value of say John Smith and then type into the address input type as well.
Now I want to grab all this html and mail it off. I know how to do the mailing portion, but the grabbing the html I'm not getting. I can grab the html in the label, but the text that that user typed in is not included in that text. So how do I get that html and the text the user typed in. Any ideas.
thanks
shannon
You need to encode the html to store them securely.
Use literal control instead of label or text controls.
Check this link for the first option.
Thanks :)
and you can use a way like this :
<input id="textField" type="text" runat="server"/>
C# - Code Behind
Mail.Send(textField.Value);
and don't forget to use ValidateRequest="false" in the header section of asp.net..
:)
You can iterate through the Request items to get the submitted values. If you want to send of an email which substitutes the entered values for the HTML input fields, you'll have to parse out the form HTML to find your input fields:
<input type="text" id="firstName" name="firstName"
style="width: 300px; height: 22px;" />
And then replace it with
Request.Form["firstName"]
Notice that the input fields will need identifiers so you can retrieve them from the HTTP request.
Hope this helps!
For one thing, you're really going to want to get a little more information into your html - at the very least some name attributes on the form elements:
Employee: <input type="text" name="employee" />
This way, you could create an aspx page like:
<%# Page language="C#"
autoeventwireup="true"
codebehind="DynamicForm.aspx.cs"
inherits="TempWebApp.DynamicForm" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Literal id="m_HtmlForm" runat="server"></asp:Literal>
<asp:Button id="m_SubmitForm"
onclick="SubmitForm_OnClick"
runat="server"
text="Submit" />
</div>
</form>
</body>
</html>
Then in your code you read your html from the database into the .Text of the literal control:
using System;
using System.Web.UI;
namespace TempWebApp
{
public partial class DynamicForm : Page
{
protected void Page_Load(object sender, EventArgs e)
{
m_HtmlForm.Text = getFormData();
}
protected void SubmitForm_OnClick(object sender, EventArgs e)
{
// Just showing we've picked up the form data.
// You'll also see ViewState and others in here.
foreach (string key in Request.Form.AllKeys)
{
m_HtmlForm.Text += string.Format("<br />Key: <b>{0}</b><br />Value:<br />{1}<br />", key, Request.Form[key]);
}
}
private string getFormData()
{
// Excluded for brevity
}
}
}
Obviously, in your button/postback handler, you would need to ensure you have the original HTML from the database, and then either modify the input elements to add a text attribute to them with the value, or more likely, replace them with the actual values - otherwise you'll have to do lots of additional parsing of the form if your users start saving forms with radio buttons, check boxes, select lists, etc.
