This is highly likely to be a stupid question, so my apologies. But I can't seem to find an answer anywhere. I am brand new to ASP.net and I'm using C# for the code behind (I have experience with C# from a WinForms project I did, also in Visual Studio)
I have a page, a register for an account page, on the website and I want to be able to access the TextBox that contains email and password etc. I thought it would be something like textboxname.getText() or similar to get what the user has typed into that box when they press submit (clicking submit is my Event) but I don't now how to make it recognize that textboxname is the ID.
For example:
<input type="email" class="form-control" placeholder="Enter Email" id="email"/>
My email TextBox has an ID of 'email'. In code, if I try to type email.getText(), it does not recognize that email refers to that TextBox. If I could even get it to recognize the ID, I could figure out the rest from there.
Thank you for listening to my excessive beginner ranting! If any extra details are necessary I'll add them, just ask.
Resolved! - For some reason it did not generate a designer for my pages when i created the web forms, so i regenerated the design.cs and it is working! :D Thanks for help anyway!
Be sure your markup is correct on front end - even if you are a space off between quotes it can mess things up.
<asp:TextBox id="email" runat="server" Text="Email" />
email.Text = "your text here";
You should use email.Text; (since it's a property, no a method) instead of email.getText(). Also make sure your control has runat property equals to "server" on HTML.
On your page
you have to declare a form with a submit button and within this form you can have your textbox.
<form id="myForm" runat="server">
<asp:TextBox id="TB_Email" placeholder="Enter Email" runat="server"></asp:TextBox>
<asp:Button ID="Btn_Submit" runat="server" Text="Submit" OnClick="Btn_Submit_Click" />
</form>
Code behind
protected void Btn_Submit_Click(object sender, EventArgs e)
{
// here you can access the value of your email-textbox
String email = TB_Email.Text;
}
Use:
<input type="email" class="form-control" placeholder="Enter Email" id="email" runat="server"/>
or alternatively,
<asp:TextBox id="email" runat="server"/> /*Add any other attributes you need*/
In the code behind:
email.Text="your text here";
Without runat="server" attribute, your control is just a HTML control and hence you cannot access it from the server side code(code behind).

I am new to telerik controls.
I have a aspx form with HTML controls on it. Data will be submitted using post method. I want to use Telerik Captcha on my page.
I have added following code on my aspx page :
<form id="frmYourDetails" runat="server" method="post" action="save.aspx">
Number: <input type="text" name="CustomerNumber" id="CustomerNumber" pattern="\d{2}-(?:\d{4}-){3}\d{1}" maxlength="19" title="xx-xxxx-xxxx-xxxx-x" required >
Name : <input type="text" name ="CustomerName" id ="CustomerName" required >
<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />
<telerik:RadCaptcha ID="RadCaptcha1" Runat="server" ErrorMessage="The code you entered is not valid." Display="Dynamic"></telerik:RadCaptcha>
<button type="submit" id="btnSubmit">Save</button>
</form>
How do i validate if user has entered correct value in textbox that comes with RadCaptcha? I want this validation on client side if possible.
Captchas do not validate on the client, only on the sever for security reasons (if they did on the client they would be next to useless).
Call the Validate() method of the captcha or the page and check the IsValid property of the captcha.
You can see more options by using the RadCaptcha events in this demo http://demos.telerik.com/aspnet-ajax/captcha/examples/serversideevents/defaultcs.aspx
I want to place two Zurb Foundation 5.5.2 modals on the same page. One modal contains a customized <asp:Login> and the other contains a customized <asp:CreateUserWizard>.
I've created two separate user controls for this purpose. Independently, they work great. However, when I try to place both of them on the same page I either get a KeyError or the user can't login.
The problem is that the ID="UserName" and ID="Password" are required for both the <asp:Login> and <asp:CreateUserWizard>.
There is custom ASPX similar to this inside of each of these ASP element tags.
<asp:TextBox ID="UserName" runat="server" />
<asp:TextBox ID="Password" runat="server" TextMode="Password" />
Obviously, I can't have identical / clashing IDs on the same page, but ASP.NET expects to find an ID of UserName and Password inside of <asp:Login> and <asp:CreateUserWizard>.
I tried changing the Password ID inside <asp:Login> like so:
<asp:TextBox ID="Password_Different_ID" runat="server" TextMode="Password" />
and I get an error.
LoginUserModal: LayoutTemplate does not contain an IEditableTextControl with ID Password for the password.
I did the same thing for <asp:CreateUserWizard> and I get.
CreateUserWizard1: CreateUserWizardStep.ContentTemplate does not contain an IEditableTextControl with ID Password for the new password, this is required if AutoGeneratePassword = true.
I set AutoGeneratePassword="false", and I get the exact same error message even though I set it to false.
Any idea on how to change these IDs, or another way to solve the problem?
When I use browser remembered password, after login, some textboxes in my forms shows username.
I am confused, how it works?
Please provide solution to avoid this problem?
Set TextBox property TextMode as Password
or try this
TextBox1.Attributes.Add("autocomplete", "off");
<form id="Form1" method="post" runat="server" autocomplete="off"></form>
Using Javascript you can also delete history of textbox
function disableautocompletion(id){
var passwordControl = document.getElementById(id);
passwordControl.setAttribute("autocomplete", "off");
}
Try:
<asp:TextBox ID="MyTextBox" AutoCompleteType="Disabled" runat="server" />
this renders as:
<input id="MyTextBox" name="MyTextBox" type="text" autocomplete="off" />
for more info MSDN for autocomplete

Before we begin, I would like to convey that I have limited to no knowledge on the JavaScript language. The only things I've used is JQueryUI - and even that is copy paste.
Currently, I have a user registration page, with all the standard TextBox inputs. I would like to, however, slide down a secondary 'Confirm email' and 'confirm password' whenever a user enters text into the original text box.
I understand the community likes to help those who can prove they helped themselves, but the only thing I currently have to show is me trying to lookup solutions for this and failing.
Could someone please show me a way to do this?
Edit: Code of the password box
<div class="ctrlHolder">
<asp:Label ID="Label9" runat="server" Font-Bold="True" Text="Password"></asp:Label>
<asp:Label ID="Label11" runat="server" CssClass="styleLabelWatermarkWashout" Text="**********"></asp:Label>
<br />
<%--data-default-value="Placeholder text"--%>
<asp:TextBox ID="txtRegisterPassword" runat="server" CssClass="textInput styleTextBoxCenter required"
TextMode="Password" MaxLength="20"></asp:TextBox>
</div>
So, assuming you can create markup similar to this:
<div class="ctrlHolder">
<asp:Label ID="PasswordLabel" runat="server" Font-Bold="True" Text="Password"></asp:Label>
<asp:Label ID="Label11" runat="server" CssClass="styleLabelWatermarkWashout" Text="**********"></asp:Label>
<br />
<%--data-default-value="Placeholder text"--%>
<asp:TextBox ID="txtRegisterPassword" runat="server" CssClass="textInput styleTextBoxCenter required" TextMode="Password" MaxLength="20"></asp:TextBox>
</div>
<div id="confirm-password-box" class="ctrlHolder">
<asp:Label ID="ConfirmPasswordLabel" runat="server" Font-Bold="True" Text="Confirm Password"></asp:Label>
<asp:Label ID="Label12" runat="server" CssClass="styleLabelWatermarkWashout" Text="**********"></asp:Label>
<br />
<%--data-default-value="Placeholder text"--%>
<asp:TextBox ID="txtConfirmRegisterPassword" runat="server" CssClass="textInput styleTextBoxCenter required" TextMode="Password" MaxLength="20"></asp:TextBox>
</div>
You'd want to add some CSS rules to make #confirm-password-box hidden by default. Then, add this script code somewhere on the page (preferably as close to closing </body> tag as possible):
<script>
$(function(){
$('#<%: txtRegisterPassword.ClientID %>').on('blur', function(event){
$('#confirm-password-box').slideToggle('slow');
});
});
</script>
The blur event occurs when the control loses focus. You don't really want to listen for keyup, since that would require this code being called every time a user entered a character into the password box...
Note that this particular chunk of jQuery code requires jQuery 1.7 or higher, so use NuGet to update your script reference (if you're not using anything else that requires an older version of jQuery).
I would add a reference to jquery to the page you are working on.
Then make a new script (on the page or in a separate .js file) which attaches a new function to the onkeyup event for the textboxes. Something like this.
$(document).ready(function()
{
$('mytextbox').bind('keyup', function() {
$('myCOnfirmationTextbox').slideDown();
};
});
This will attach this function to all elements corresponding to the "mytextbox" class or ID. So if you have an input <input type="text" id="email" class="emailInput"/> then you would use $('#email') to bind the event to this particular element. Or you use $('.Emailinput') to bind to all input elements for emails.
By the way, I haven't tested the code, but this or something very similar should work.
If you use a separate .js file, then don't forget to reference it in your page as well.
You can use innerHTML to have a new textbox beneath the email textbox once that box is filled. I could give you the code if you can post the code over here
Replace the controls ids in this answer as per your html.
You can show the confirm controls in the following way.
$('#password').onfocusout(function() {
// This will show once you complete entering Email and Password.
$('#confirmEmail').attr('display', 'inline');
$('#confirmPassword').attr('display', 'inline');
});
Let me tell how you can achieve confirm Email. Same thing can be used to achieve confirm password.
When you focus out of confirm email textbox compare the emails entered by the user in Email and Confirm Email textboxex.
This can be done in following way
$('#confirmEmail').onfocusout(function() {
if($('#confirmEmail').val() == $('#Email').val())
{
// Emails entered are same
}
else
{
alert('Emails entered are not matching. Please reenter emails.');
}
});
Similarly you can check for confirm password.
The following code does not work. The markup is in a User Control and I suppose that's why ClientID returns the wrong prefix for the TextBox id.
Markup:
<INPUT id="txtName" runat="server" maxlength="50" style="WIDTH:100px">
<INPUT type="button" value="Find Your Doctor" id="btnFind" runat="server"
style="MARGIN-LEFT:10px;WIDTH:130px">
Code-Behind:
btnFind.Attributes.Add("onClick",string.Format("DoctorLink
('{0}',document.getElementById('{1}').value,{2});",
row["ZipCode"],
txtName.ClientID));
Results in browser:
<input name="DoctorsMainArea1$ctl01$txtName" type="text"
id="DoctorsMainArea1_ctl01_txtName" maxlength="50" style="WIDTH:100px" />
<input name="DoctorsMainArea1$ctl01$btnFind" type="button"
id="DoctorsMainArea1_ctl01_btnFind" value="Find Your Doctor" style="MARGIN-
LEFT:10px;WIDTH:130px" onClick="PrepareDoctorLink('90210',
document.getElementById('DoctorsMainArea1_ctl00_txtName').value);" />
As you can see, the parameter for the JavaScript call is DoctorsMainArea1_ctl00_txtName, but the actual id of the input element is DoctorsMainArea1_ctl01_txtName.
Any idea how to fix this? jQuery? I am not so much interested in an explanation of what's going on (maybe there is another control on this page that is interfering), but a more robust way to solve the problem.
I don't know which asp.net version you are using but in 4.0 you can declare inside any server control ClientIDMode="static" and it will give you the exact id in browser.
Example:
<asp:Textbox id="txtName" runat="server" ClientIdMode="static"/>
Others are predictable, inherit and it can be used with ClientIdRowsuffix.Can be used at page level and even on master pages and even in web.config file.
Example on web.config file:
<system.web>
<Pages clientIDMode="predictable"/>
other system web properties
</system.web>
Watched Craig shoemaker's Video at tekpub, you can also read more about it at Rick's bloglink text. It's pretty cool tho.
You should try moving the code that adds the onclick attribute to the button in the PreRender event (or OnPreRender override) in your page or user-control. That should probably get the ClientID right.
A fast solution:
btnFind.Attributes.Add("onClick",string.Format("DoctorLink
('{0}',document.getElementById('{1}').value,{2});",
row["ZipCode"],
"DoctorsMainArea1_ctl01_" + txtName.ClientID));
This happens because you have a content placeholder in your page somewhere.
another solution:
html tag:
<input type="text" name="txtName" id="txtName" />
code-bind:
string txtName_value = Request.Forms["txtName"];
and you can get the value
just use the html control.
