Web Forms :: At Least One Checked Validation For CheckBox Inside ListView Using Custom Validator
Jun 26, 2013
With respect to my previous questionListview Checkbox checked using jquery . The code works fine and it checks for any checkbox checked in listview and returns a alert msg but now it does not check for any required field validators in the page. I the checkbox is checked it fires button click event. I need to check for validators also and after that only it must check for checkbox validation. The link for previous question is [URL] .....
I need to merge the code for required field validation check with checkbox check.
having one listview in the listview first column is checkbox.on the out side of the listview there is dropdown list and button. i have to make functionality is on button click need to check atleast one checkbox has to selected if not then has to send alert for this. atleast select one checkbox from listview.
I have repeater control which contains checkbox. when user click on download button I want to check whether user select atleast on checkbox using javascript not jquery.
I have an ASP.NET MVC 2 project in which I've created a data transfer object to receive data from a web page form. The form has two groups of checkboxes on it. I want to validate the object to make sure that at least one of the checkboxes in each group is checked.
I'm doing the validation on the server side so that a user won't be able to hack around any client-side validation. (I will add client-side validation with jQuery later; that's easy.)
My understanding is that I have to create my own custom ValidationAttribute for my data transfer object class, but I don't understand how to create and use one that can accept an arbitrary list of checkbox properties to make sure that at least one of them is true. I am guessing I will have to call the attributes like this:
[AtLeastOneCheckbox("set1check1", "set1check2", "set1check3", ErrorMessage = "You must check at least one checkbox in set 1.")] [AtLeastOneCheckbox("set2check1", "set2check2", "set2check3", "set2check4", "set2check5", ErrorMessage = "You must check at least one checkbox in set 2.")] public class MyFormDTO { ... }
What would the implementation of AtLeastOneCheckboxAttribute look like?
Or is there a different way that I should do this kind of validation?
I have tinkered with this a bit, and would like to know how to require fields based on the status of the checkbox.
The page I am referring to is located at www.libertyhtc.com/billsubmit.aspx.
Under Step 3, say, if a user checked the Television box, the textboxes for service provider, and authentication would be required. the upload file can be left blank if the user chooses to do so. This would be true of the Internet, Home Phone, and Cell Phone areas.
Now, later on, once the user clicks submit bill, I would like to have it go to a page that would bring up a page with the service agreement. The service agreement would pull data that they just put into the form before clicking that button. This step is necessary to allow the user to print out the page for their records.
Finally, there should be a button that, when clicked, will send all the data in the first form (located at www.libertyhtc.com/billsubmit.aspx) to a specified email account. I have sent data to an email before, but the code sample I used wanted the stmp details and logon information in the source code of the page, and for obvious reasons, i dont want users to know this.
Iam developing a custom checkbox control deriving from the 'compositecontrol' which i need to use it for a composite control purpose.
public class TngCheckBox : CompositeControl {
i have written the required properties which are working fine except the "checked" property. here is my code for 'checked' property. i tried both the below ways (commented one and not commneted) . the problem is the 'checked' value is not setting the value at the get set part of the property.its assigning the value at the design time , but when i check and uncheck its not updating the property value.which is resulting me wrong .

I have a GridView that I was previously populating via an ObjectDataSource, and this code was working perfectly (ie, when the checkbox was checked Checkbox.Checked = true):
I've been trying to get a custom validator component working that ensures at least one checkbox from a checkboxlist has been checked. I've been used some code I found on dotnetjunkies.com but the client-side validation didn't work. I've been attempting to modify it to get the client-side javascript validation to work with no luck. Basically, I compile the below code into a DLL and add it to my bin folder.
I am using EF4 and ASP.NET MVC 2 for my web application. I am also using data annotations for my validation.
Is the following possible? If so, how would I implement it? I have a checkbox, and a from and to date. The from and to date are not required fields, but when the checkbox is ticked then the from and to dates are required fields. Then the required error must display.
I have created a gridview and added a headertemplate field inside templatefield. Inside header template field I have added a button and a condirmbutton extender. confirmbutton extender uses modelpopup with ok cancel. This works fine but with one problem. I want this popup to open on button click only if user has checked atleast one checkbox from gridview. So far it shows this modelpopup everytime even user hasn't checked anything.
I am using a PasswordRecovery Control and have changed one of the validators to a custom Validator, however, OnServerValidate neer seems to get called.
Can someone tell me how to get the OnServerValidate to work correctly?
I have a repeater control on my page. Here's my code:
[Code]....
I would like to change a background color of the item's <div> when user checks the chechbox. I have an event handler for CheckedChange event but I don't know how can I get access to this div from the event handler.
I need the ability to check a box and then store or remove the text of the checkbox clicked to my sql server database. see my code below that is written in vb.
<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="SBN_Company_Cat_Types.aspx.vb" Inherits="ShopBuyName_Test_Site.SBN_Company_Cat_Types" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
I have the following validation which is working fine for the rest of my fields, but trying to get a custom validator to work as part of the validation summary for a checkbox but no joy.
This is what I have at the moment
<script language="javascript" type="text/javascript"> function ValidateTandCs(source, args) { args.IsValid = document.getElementById('<%= optIn.ClientID %>').checked; } </script> <asp:ValidationSummary CssClass="highlight" id="ValidationSummary1" HeaderText="<p>Please amend these errors below to continue with your application.</p>" Runat="server" /> <asp:CheckBox id="optIn" runat="server"></asp:CheckBox> I agree to the terms and conditions of this site and I wish to Opt In for registration. <asp:CustomValidator ID="valTandCs" ClientValidationFunction="ValidateTandCs" ValidationGroup="ValidationSummary1" runat="server" ErrorMessage="Please accept Terms and Conditions before submitting."> </asp:CustomValidator>
But when I click submit I only see the error messages for my other fields and nothing for this checkbox..
I am using Checkbox in Gridview item template once it checked it cant be unchecked..once i click the button the checked box should automatically unchecked.
In my asp.net website; i have REPEATER control having child control checklistbox , dynamically generates in code behind.I would like to know how can i write javascript function where i have to check at least one checkbox should be checked.
I have a gridview inside which there are 4-5 checkboxes. In that gridview, I have 10 rows too. So, Now what i want is.
IF I check, 2 checkboxes and don't check remaining checkboxes. how to save the value of the checked checkboxes value as Y and unchecked checkboxes value as N into the database.
