I have a long form for my users to fill out. Is there a way to hyperlink the error message in ValidationSummary to the specific text field?
The easiest way to do this is with straightforward HTML anchor tags <a>, you can include the HTML in the ErrorMessage property of your validation control which will be displayed in your ValidationSummary control. For examples
<asp:ValidationSummary ID="ValidationSummary1" runat="server" />
<asp:Button ID="Button5" runat="server" Text="Submit" />
<br />
<div style="height:800px"></div>
<a name="TextBox1"></a>
Required Field
<asp:TextBox ID="TextBox1" runat="server" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ErrorMessage="Required Field is Required <a href='#TextBox1'>Click Here To Go To</a>"
Text="***"
ControlToValidate="TextBox1" />
A more elegant approach would be to combine the above approach with jQuery using the scrollTo function and perhaps highlighting the field. You can include this jQuery/Javascript code in the onclick property of the anchor tag.
I've implemented this before in the same way #jdmonty had suggested - by adding the anchor tags to each RFV's ErrorMessage attribute. Eventually I found this too tedious so I drummed up some jQuery to do the work for me. This snippet will wrap your validation messages in anchor tags with the href=#targetControl, which of course when clicked scrolls to the target input.
Add this to the $(document).ready(); portion of your script code.
var validators = Page_Validators; // returns collection of validators on page
$(validators).each(function () {
//get target control and current error validation message from each validator
var errorMsg = $(this).context.errormessage;
var targetControl = $(this).context.controltovalidate;
var errorMsgWithLink = "<a href='#" + targetControl + "'> " + errorMsg + "</a>";
//update error message with anchor tag
$(this).context.errormessage = errorMsgWithLink;
});
You could add some additional jQuery as #jdmonty suggested to smooth the scrolling. You can also use the css pseudo class ':focus' in your style sheet to add styles for 'active' input textboxes, something like input[type=text]:focus{background-color:red;} to really accentuate when they are focused.
P.S. I know this question is old but I just found it today while seeing if anyone had come up with a more elegant solution, so for anyone else in my shoes, here ya go.

How to add an additional css class from code behind using ASP.NET?
CURRENT TEXTBOX
<asp:TextBox ID="txt" CssClass="MyClass" runat="Server" />
DESIRED OUTPUT
<asp:TextBox ID="txt" CssClass="MyClass Error" runat="Server" />
Testing
txt.CssClass = "Error"
This replaces current css class.
txt.CssClass = "MyClass Error"
This works but but is greatly inefficient having to specify class.
txt.Attributes.Add("class", "Error")
This only works if no initial class is set.
txt.Attributes("class") += " Error"
This does not work for me.
Add additional CssClass like this:
txt.CssClass = txt.CssClass + " Error"
The above can also be abbraviated as:
txt.CssClass += " Error"
I know that you were looking for a quick one-liner. However, this previous answer may prove useful going forward:
How to add more than 1 class to an element in ASP.NET?
I have a asp label that I need to be able to change according to the code behind. How can I do this?
ASPX: (The first part works correctly only for "TestA#abc.com" and the second part dynamically changes the label (EmailLabel) according to the "if" statement in the code behind. How can I integrate these two so the label is mailto? Thanks.
<p>Email at TestA#abc.com.</p>
<p>Email at <asp:Label ID="EmailLabel" runat="server"></asp:Label>.</p>
Code Behind:
public changeLabel()
{
if (//Some Condition Here)
{
this.EmailLabel.Text = "TestA#abc.com";
}
else
{
this.EmailLabel.Text = "TestB#abc.com";
}
}
What you are trying to do there won't work. Label's render out as <span> tags, so it will never be "clickable". You want to do something more like this:
<p>Email at TestA#abc.com.</p>
<p>Email at <asp:LinkButton ID="EmailLabel" runat="server"></asp:LinkButton>.</p>
And then instead of changing the Text property, change the NavigateUrl property.
You could also use an HtmlControl, which is basically a standard HTML tag that you add the runat="server" attribute to.
<p>Email at <a id="EmailLabel" runat="server" href=""></a>.</p>
You would then be able to modify this <a> tag via server side code, the properties will be slightly different, but now you've got a real live anchor tag to work with.

For your Label, just remember that .Text is the server equivalent of .innerHTML so you can put whatever HTML you want right into the asp:Label when setting .Text. Just watch out for cross-site-scripting exploits.
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.
I have text boxes and it has values let say. I am calling my javascript method on one of textbox 'onblur'. my function is:
function CalculateExpectedProductPrice() {
alert("hi i called");
var originalPrice = document.getElementById('hdnSelectedProductPrice').value;
var numberOfLicenses = document.getElementById('txtNumberOfLicense').value;
var enteredAmount = document.getElementById('txtAmount').value;
alert(originalPrice);
alert(numberOfLicenses);
alert(enteredAmount);
}
i am getting alert message as ""hi i called". but not further.
But some i am not getting values of these controls.
*Edited:* My HTML is :
<asp:HiddenField ID="hdnSelectedProductPrice" runat="server" />
<asp:TextBox ID="txtAmount" runat="server" Width="250px"></asp:TextBox>
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="txtNumberOfLicense" runat="server" Width="35px" ></asp:TextBox>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="txtNumberOfLicense" EventName="" />
</Triggers>
</asp:UpdatePanel>
Will there any impact master-content page . because script is in content page and html also on same content page.Also let me know you, I am using wizard control where as all these controls are resides on second step of wizard. will that make any impact ?
Edited:
I think wizard control making here matter. As i started my firebug and review the generated html it assign the Id dynamically to those controls which are inside the wizard. thats why javascript unable to find the expected control .
eg for txtAmount text box which is inside the wizard control getting name as :
ctl00_ContentPlaceHolder1_Wizard1_txtAmount
but certainly i would not prefer to use this generated Id. So is there any remedy to find control inside the wizard control and get - set values ?
get id of the control as shown below
var enteredAmount = document.getElementById('<%=txtAmount.ClientId%>').value;
It's impossible to say for certain with your not having quoted your HTML (!), but the usual reason for this is confusion between the id and name attributes. document.getElementById works with the id attribute, but people tend to think it works with the name on input fields, which it doesn't (except for on IE, where getElementById is broken).
(The other thing to remember is that id values must be unique on the entire page, but looking at the IDs you quoted, I suspect you're okay on that front.)
Update: It works if you use ids:
HTML:
<form>
<input type='hidden' id='hdnSelectedProductPrice' value='10'>
<input type='text' id='txtNumberOfLicense' value='2'>
<input type='text' id='txtAmount' value='3'>
<br><input type='button' id='theButton' value='Click Me'>
</form>

As T.J. mentioned we really need to see your html code, without seeing it it could be that you are looking for an elements attributes.
So lookup the element as you are already with
var element = document.getElementById('product');
Once you have the element you can query its attributes
var price = element.getAttribute('price');
If its "ASP.net server control" then you will have to do it like this:
var originalPrice = document.getElementById('<%=hdnSelectedProductPrice.ClientID %>').value;
if you use Asp.Net 4.0 and your textbox is unique on the entirepage you can add ClientIDMode="Static" in attribute of your textbox
<asp:TextBox ID="txtAmount" runat="server" Width="250px" ClientIDMode="Static"></asp:TextBox>
I am using a button that has to be invible and should be used by a javascript function.
<asp:Button ID ="btnDummy1" runat="server" Visible ="true" OnClick="btnSubmit1_Click" width="0px" height="0px"/
I cannot keep visible = false as it the javascript will not use invible content in the poage. I havetried to give width=0 and height=0, still it showws up in Chrome. What do you guys think i should do?
Thanks in advance :)
A pretty clean approach in ASP.Net it give it a "hidden" class:
<asp:Button ID ="btnDummy1" runat="server" CssClass="hidden" />
Then in your stylesheet:
.hidden { display: none; }
If you set it to Visible="False" then the code will not be executed.
Instead I think you should wrap it in a <div> and set display:none via css:
<div style="display: none;">
<asp:Button ID ="btnDummy1" runat="server" OnClick="btnSubmit1_Click" />
</div>
adding style="display:none" would hide the button till you make it visible again
<asp:Button ID ="btnDummy1" runat="server" OnClick="btnSubmit1_Click" style="display:none"/>
How about
style="display:none"
for the button instead of Visible = "true".
Can you just use a hidden form field in this case? This is generally the preferred method of passing information along.
See http://www.tizag.com/htmlT/htmlhidden.php
<asp:Button ID="btnMyOrders" runat="server" Text="my orders" CssClass="dropdown-item" OnClick="btnMyOrders_Click" Visible="False" />
Example then in Form(){
btn.Visible = true; to show it again
}
I think the first question you should ask yourself is : why would I put in my HTML doc a button that should not be visible ?
An HTML document should be used ONLY TO DESCRIBE A CONTENT'S SEMANTICS. So an HTML doc should ONLY contain the content you want to publish and extra data to explain the content's SEMANTIC !! NOTHING about the way it is displayed, NOTHING about the way it behaves !!
All displaying and behaviors questions should be managed with CSS and Javascript, NEVER within HTML itself.
Any element needed for Javascript only purpose should be added in the doc by Javascript itself !
You should never find, in an HTML doc, such things as prev/next buttons for a javascript picture gallery for example. The HTML doc should only contain the pictures list, than your JS script will change the way this list is shown, making it a eye candy gallery and add buttons for navigation.
So in your example, your saying you want to add in your HTML doc an invisible button with some Javascript actions on it.... that's probably an example of some content that should never be in the HTML doc.
