Javascript - Disabled Radio Button Losing Value After Postback
Feb 14, 2011
I have two radio buttons that are disabled with javascript when the page loads. RadioButton1 is checked by default. When I click the button to do a postback, the RadioButton1 is no longer checked.
Here's my code sample. The code behind is empty.
<asp:RadioButton ID="RadioButton1" runat="server" GroupName="group" Checked="true"/>
<asp:RadioButton ID="RadioButton2" runat="server" GroupName="group" />
<asp:Button ID="Button1" runat="server" Text="Button"></asp:Button>
<script type="text/javascript">
window.onload = function () {
var RadioButton1 = document.getElementById('<%= RadioButton1.ClientID %>');
var RadioButton2 = document.getElementById('<%= RadioButton2.ClientID %>');
RadioButton1.disabled = true;
RadioButton2.disabled = true;
};
</script>

My current structure:
1. An asp.net radio-button list with autopostback = true. The radio-button list has 2 items - Yes and No.
2. An asp panel that has 2 textbox.
Current behaviour:
When the user clicks on the radio-button list (i.e. Yes), the panel is made visible.
My clients wants the same functionality without the page refresh (i.e. the postback).

I have a set of radio buttons that are all disabled, and one of them is selected. In IE8, when I print the web page, the selected radio button is not showing as selected. However, this works fine in FireFox.

I have a web application that shows a page containing between 6 and 20 AJAX UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here:
[URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button
clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)
Not sure if this is an AJAX issue, or general ASP.NET UI issue, so I'm posting in two forums on this one.

I am creating a ASP.Net server control to manage locations. The control is a composite control containing several text-boxes, labels, and a link button. I use the AJAX Control Toolkit to provide a modal popup which contains a Bing map. All the Javascript is in its own file and used as an embedded web resource.
The link button is what opens the modal popup. It also needs to call a Javascript function that initializes the Bing map (onclick = "GetMap();"). There are instances when this server control is placed within an Update Panel (and there is no way to avoid this). When in an Update Panel the link button loses its onclick event. I understand that this is because during an async postback the portion of the DOM that defines the content of the Update Panel is thrown out and reinitialized, resulting in the event breaking. When the control is not in an Update Panel everything works as intended.
I have tried registering events on Page.Load and Page.Init, like so:
[Code]....
I have also tried flat out writing the function call to the page:
[Code]....
I have put breakpoints on the lines inside each delegate and they do not get hit. I am not aware of any special way to register events of a composite control's child control or the Page.Load/Page.Init events when being done inside a server control. Is there some special way to register these events? (Note: Both those code blocks above are in my CreateChildControls() method)
Below is the GetMap() Javascript function. As you can see it is pretty straight forward.

standard webcontrol:
<asp:Button ID="cb_btnSubmitData" Text="Submit data" OnClick="SubmitData_Click" runat="server" />
added this in the Page_Load eventhandler
this.cb_btnSubmitData.Attributes.Add("onclick", "addTextToLabel('message', '" + this.cb_btnSubmitData.ClientID + "');return true;");
and this is the javascript that is executed when the button is pressed:
<script type="text/javascript">

I have a set of radio buttons for "yes" and "no" values which have a name="choice". "yes" is checked by default. They're both runat="server". I read the choice on postback like below. It works perfectly fine as long as the validation doesn't fail. For example, if I select "no" and validation fails on postback, I still see "no" selected. But if I submit the form after correcting everything, the value read is "yes" on server side! Is this a bug in .net, and if so, how do i fix this?
foreach (string key in Request.Form.AllKeys)
{
if (key.EndsWith("choice"))
return Request.Form[key] == "yes";
}

I'm trying to disable a link button to prevent the user from submitting several times.
I've seen many questions like this here on SO, most people suggest the following javascript:
button.disabled = true or button.disabled = 'disabled'
Which indeed disables the button (the button is greyed out), but the problem is that it's still clickable, and still submits!!
Here is my stripped down code:
function ValidateButton(button){
// some other code
button.disabled = true;
button.value = 'Processing...';
}
<asp:LinkButton Text="Submit" ID="btnSubmit" runat="server" onclick="btnSubmitRow_Click" OnClientClick="return ValidateButton(this);"/>
Why is the button still clickable, and submits after being disabled ? The button text is still "Submit" not "Processing...', why?

I'm using the code the above and running into an error i can't quite figure out. Maybe its something simple or maybe it's something that can't be done. Not sure.
I created a user control (button) that references a javascript file like this:
string url = ResolveClientUrl("./Scripts/main.js");
function SubmitButton_Click(e) {
try {
var src = typeof (event) != 'undefined' ? event.srcElement : e.target;
[Code]....
The error that i am running into is this:
The buttons in the update panel work everytime without any problems. When i click a button in the update panel and then click a button outside the update panel it chockes on this line of the above javascript.
src.aspnet_onclick();
The value of aspnet_click() is 'SubmitButton_Click(e)'. This is incorrect which causes it to choke.
The value should be 'onclick(event)'
For some reason when click the button inside the update panel and then the button outside the update panel causes this javascript error but I am not sure why the aspnet_onclick() is incorrect.

This is likely a n00b question, but I can't seem to find any info on how to solve it. Here's the scenario:
I have a Textbox and a RadioButtonList in an UpdatePanel, both with AutoPostBack turned on (they need to be, can't turn it off on the text box))
The user enters some text in to the textbox, then clicks one of the Items in the radio button list.
Because the textbox post back is executing, the radio button is losing the value that the user selected.
How can I workaround this?

I'm trying to write a javascript to check if the 5th element in the radiobutton list is selected then:
1. alert 'enter an amount' if the txtbox is empty
2. alert 'amount must be greater than 10' if the txtbox value is less than 10
My code is shown below, but I guess I'm missing something because the code didn't executed.

What I want to do is whenever you click a radio button on the Group1Most RadionButtonList, it will disable the corresponding radio button on the Group1Least RadioButtonList. The problem is I can't figure out how to select an individual radio button within the RadioButtonList.

Using jQuery I want to be able to click an element which will also checks it's related radio button. I had this working fine until we had to add runat="server" to the radio buttons.When I apply this it prevents my jQuery function from working how to get round it, heres a simplified version of the code:HTML
<input type="radio" runat="server" id="sector1Radio" name="SectorGroup" title="Sector1" />
jQuery
$('#SomethingElse').click(function() {
$('input[title=Sector1]').attr('checked','checked');
});
I've found out that when its converted to a .net control instead of checked="checked" (as it would be usually) it is just Checked, so I changed that but on inspecting the DOM in multiple browsers, none of my radio buttons are being checked(Are there any other ways I can use jQuery to check a radio button that has runat="server"?

[DefaultValue(true)]
public bool IsModificationMode
{
get
{
return (bool)Session["ModificationMode"];
}
set { Session["ModificationMode"] = value; }
}
In the PageLoad, I set it's value.
Now after the Postback, I am losing it's value having a a NullReferenceException
