Show Html Checkbox As Neither Checked Or Non-checked?

Oct 22, 2010

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>

MVC Validator To Make Sure At Least One Checkbox Is Checked

Dec 20, 2010

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?

MVC :: Return Value Chosen For Html.checkboxfor?

Feb 17, 2011

I love MVC, coming from WebForms development, but there are things that don't make any sense to me. The "Error executing child handler" occurs anytime a vast number of things happen, for instance. It's very close to a useless message. In order to get the actual cause, I click on Debug/Exceptions and check the "Common Language Runtime Exceptions", and then reload the View. Presto! It shows the cause of the error.

Another thing I'm wondering about today is the FormCollection value of the Html.CheckBoxFor control. Checkboxes in general seem badly designed in html, and MVC didn't improve on it much. When processing a POST, if a regular checkbox isn't checked, it simply won't show up in the list of posted elements. Great. Instead of just grabbing it by name in the FormCollection and testing its value, instead I have to test whether or not it exists in the FormCollection. Not very intuitive. The Html.CheckBoxFor is a variant on the same theme. It always shows up in the FormCollection, but with a similarly non-intuitive return. If it's not checked, it yields a value of 'false', which can simply be converted to boolean and processed as normal. But if it is checked, it returns 'true,false'. Super. Now, instead of converting its value to a boolean directly, I have to test the string returned for the index of 'true' and return that instead.

I find this close to as aggravating as the Linq To Sql Sum() method bug. If I run a Select() method on a given numeric property and run Sum() to add them all together, if an empty result set is returned by the query it throws an exception. Now, if I was looking at a bunch of totals to add together, and none of them had anything entered, what would I write in the sum box? Error? Exception? Nope, it would be zero. I fully understand that if no results were returned then nulls cannot be added, but according to the intitial documentation this method was supposed to return zero in such an instance regardless, because that's just common sense. Enough of that rant. Does anyone know why this return value was chosen for Html.CheckBoxFor?

I have this C# code in a Razor view:

But it's complaining. Why, and what is the right statement?

Make Index.html Show Instead Of Default.aspx?

Feb 17, 2011

We are working on an aspx site that we would like to not show users until we are ready to launch. The Default.aspx seems to have more "power" over my index.html file. All I would like to do is show the index.html by default and when working on the site, we can navigate to Default.aspx and work from there.

Web Forms :: Why CheckBox Is Not Getting Checked On OnCheckedChanged

May 14, 2010

I have a CheckBox field inside a Formview.

<asp:FormView ID="_fvApplicant" runat="server" DefaultMode="Edit" OnItemDeleting="ApplicantItemDeleting" Width="100%" DataSourceID="_dsApplicant" ondatabound="ApplicantFormBound">
<asp:CheckBox ID="_chkSuitable" OnCheckedChanged="test" AutoPostBack="true" CausesValidation="true" runat="server" Checked='<%# Bind("Suitable") %>' /></td>

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.

protected void test(object sender, EventArgs e)
{
CheckBox vld = (CheckBox)_fvApplicant.FindControl("_chkSuitable");
vld.Checked = true;
_fvApplicant.DataBind();
}
protected void ApplicantFormBound(object sender, EventArgs e)
{
var chk = (CheckBox)_fvApplicant.FindControl("_chkSuitable");
if (chk != null)

AJAX :: Checkbox In Reorderlist Can't Be Checked In IE?

Feb 6, 2010

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:

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<table>
<tr>
<td colspan="2">
