Security :: Ensure Checkbox Is Checked In Createuserwizard?
Jan 4, 2011
I have a standard createuserwizard control, which adds a new member to my membership database. All fine, except I need to ensure that the user checks the terms and conditions checkbox before the member is created in the code-behind page. I need this to be server-side, rather than client-side, so a javascript-reliant solution isn't a solution :)
The code-behind is like this:
[Code]....
The aspx code is like this:
[Code]....
how to add validation to the 'Terms' checkbox? I've tried a normal validator and custom validators but just can't get them to work at all.
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 am doing a survey. so basically, i will send out an email with a unique link and the person clicks the link which directs them to my aspx page. that controls i use will be bound to a datatable.
first I will need to show their existing home and email address in a control.
then i will give them 4 checkbox's to tick a certain option. also, how can I ensure only one checkbox is ticked all the time?
I will need the checkboxes to be bound as well, to show the options they chose incase they load the page again after saving.
I have an html checkbox that controls a list of checkboxes. I want this checkbox to display in a sorta "null" state where it is neither true nor false. <HeaderTemplate> <div style="width:90px"> Toggle: <input id="chkAll" onclick="javascript:SelectAllCheckboxes(this);" runat="server" type="checkbox" /> </div> </HeaderTemplate>
When clicked on particular URL, i need to pass whether user has checked REMEMBER ME CHECKBOX while logging in. How can I determine this using FOrmsAuthentication mechanism?
- How can I uncheck a checkbox using client side code when the other checkbox is checked? - Is there a way to check server side on form submission that at least one check box is checked?
Using Asp.net Webforms how can I validate that a checkbox has been checked. (I cannot do a postback) has to be in javascript (either custom - working with the existing validation controls for other fields. or using a .net validation control)
I'm creating an ASP.NET application which uses Facebook Connect and fbml tags. It also uses the LinkedIn widget. When I run this app in any browser, there are no warnings and everything works. However, in IE, a message like this comes up:
Security Warning: The current webpage is trying to open a site in your Trusted sites list. Do you want to allow this?
Current site:http://www.facebook.com Trusted site:http://localhost
(same for LinkedIn.com). I know how to fix this from a client perspective and to stop the security warning showing up. However, is it possible to ensure this message doesn't come up as it could be off putting for users who don't know how to suppress this warning? I haven't tried uploading it to my webhost, so not sure if this message will appear for everyone in production. However, I always get it on my local machine.
(None of my pages use SSL, so I don't think that's the issue. I tried using FB's HTTPS urls but that didn't make a difference).
I have a gridview with one column of checkboxes and other columns with different custom controls. What I want is that when a checkbox is checked an event is triggered which toggles the visibility of other elements in the row .
what is the code to retrieve the id associates with each checkbox and read if whether each checkbox is checked or not in the controller action(I will need to get the status in both conditions, checked or unchecked )?
In my Code Behind in test method I am trying to set the checked to true, but in the ApplicantFormBound event when i debug it is never true...any reasons why? Basically I want to set the Validator to true when checked.
I am using the AJAX ReorderList, and inside the ItemTemplate I have a label and a checkbox. Now when in firefox I am able to change the checkbox checked state, but in IE it won't allow me to do anything with it. Its weird because the checkbox becomes that blue colour like when it gets focus, but it won't put the check in it or call the postback. The ReorderList is inside an UpdatePanel, so that I can monitor when the check changes on its postback. Below is the code:
I've a list page with check box for each row.When records are selected by checking the Checkbox, it will open a pop-up window for those selected records .When the pop-up is closed, i want to retain he checked status of the checkbox in the base page, just to keep track of what i selected. But curently it is not happening.
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 created a single checkbox in the DetailsView of my Asp page. I then created VB code behind to set the value =1 if the checkbox is checked and value =0 if checkbox is not checked. I cannot get the code to work. The record will get created in my SQL database, but the checkbox field remains NULL
In SQL table, my field and datatype is: Greenfield, bit, NULL
And the VB code behind. I originally used OnCheckedChanged but that wasnt working and it was suggested of me to use DetailsView1_ItemInserting instead: (The Dropdownlists in the code are working)
Code: Protected Sub DetailsView1_ItemInserting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DetailsViewInsertEventArgs) Handles DetailsView1.ItemInserting Dim DropDownList6 As DropDownList = CType(DetailsView1.FindControl("DropDownList6"), DropDownList) Dim DropDownlist9 As DropDownList = CType(DetailsView1.FindControl("DropDownList9"), DropDownList)
I have House_info table in database that have Pay column
I have one checkbox in admin.aspx page that I bind it from database
I want if there was data in pay column checkbox.cheked=true else checkbox.cheked=false
so in behind code I wrote below code
SqlCommand _cmd = new SqlCommand("ViewSreg", _cn); _cmd.CommandType = CommandType.StoredProcedure; _cn.Open(); SqlDataReader _dr = _cmd.ExecuteReader(); while (_dr.Read())
[Code] ....
But in both condition if there was data in Pay column Or there wasn't any data in Pay column it checked checkbox. I mean in both condition it is CHKV.cheked=true
