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:
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'm using AjaxToolkit and it works just fine. In one form i'm using the Time field (MaskedEdit). I need to validate Time field only if a tickbox is ticked. Is it possible?
I am using a datalist with checkbox and datalist is in a panel. I am poping the panel by using ajax modal pop-up. When we check the checkbox the checkedchange event is firing. But, when we uncheck the checkbox the event is not firing. It is user control and it is in update panel.
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>
- 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 trying to add an item to the Reorderlist dynamically using the following code but nothing gets displayed.
Server Side Code: FieldInfo field = new FieldInfo(); field.FieldId = 1; field.Alias = "Text"; _selectedFieldsListBox.Items.Add(new ReorderListItem(field,_selectedFieldsListBox.Items.Count,ListItemType.Item)); Client Side Code: :
what I'm doing wrong? Or has anyone done this before?
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'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?
