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>
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 have two checkboxes on my form.
- 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?
How bind the data through checkbox if checkbox checked is true
View 3 RepliesI have a treeview in my .aspx: <asp:TreeView ID="tvDocCatAndType" runat="server" /> Not much else going on in the page -- two <asp:LinkButtons> and one <asp:Label>; the page is a child of a master page, so these controls are within a <asp:Content> control. I populate the treeview in code -- just 3 node levels, including the root node. All nodes have checkboxes, and I initialize all node.Checked to true. I have some Javascript to do the usual check/uncheck up and down the tree as parent and child node checkboxes are toggled.
No matter how many checkboxes I clear in the UI, on postback every single node has node.Checked = true regardless of the state of the checkbox in the UI. This is not the first time I've used a treeview, but I've never had this problem before. I created this page by light adaptation of an earlier project that works fine.
In my page,on one button click ,i am creating a checkbox dynamically and in other buton click i need whether the checkbox is checked or not.
For me every time it is showing as not checked eventhough i cheked the checkbox..
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)
View 3 RepliesI 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 .

Even though im checking the checkbox im not the checkbox checked in code behind.
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)

I want to reach checked rows item in ASP.Net Listview control.
For example:
if 3 Lines of Listview checked, I want to reach checked items value in listview.
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">

I have multiple dynamic checkboxes. I would like to find out what checkbox was checked in the controller. How do I do that? This is what I have.

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.
View 3 RepliesI 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
The beginning code for DetailsView1 is:
Code:
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" BackColor="White" BorderColor="White" BorderStyle="None" BorderWidth="1px" CellPadding="3" CellSpacing="2" DataKeyNames="ID" DataSourceID="tblEntryFormDS" style="text-align: left; margin-bottom: 0px;" Font-Bold="False" Font-Names="Arial" Font-Size="Small" DefaultMode="Insert" GridLines="Horizontal" CssClass="auto-style47">
<AlternatingRowStyle BorderStyle="None" />
The code for the checkbox within DetailsView1:
Code:
<asp:CheckBox ID="CheckBox1" runat="server" Text=" Greenfield" AutoPostBack="True" />
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)
