Javascript To Check Against Radio Button Selection?

Apr 1, 2010

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.

Web Forms :: Fetching Selection Of Radio Button?

Mar 9, 2010

My web page has one radio button and three sub radio buttons. When I click on Main Radio button, I am enabling the sub radio button using Javascript, and user can select the options. Now the problem is, when I click on submit on this page, I am unable to get the selected radio button. i.e., Suppose if I select 1st sub radio button and click on submit. I am checking in the code for sub radio button selection, I am getting no radio buttons are selected. The above condition is for first time only. Now go to another page and traverse to the page again, I am successful, i.e., I am getting the selections properly.

Radiobuttonlist - Linking To A Radio Button Selection?

Jan 20, 2011

I have an "articles" page that holds a radiobutton list and a textarea. when the user selects a radio button, the text area is populated. now the users wants to be able to point to an article via a url link. (everything is dynamic and being pulled from a db source)

by using a 3 party tool i was able to grab the exact http request (below) that will link to the users' selection. the problem is the url is extremely long. is there another way to link to the radio button selection? that way i can just modify the query string to fit a specific format.

Forms Data Controls :: Save Radio Button Selection

Feb 17, 2010

How do you save a radio button selection to a DB (within the .aspx page)? I have 5 sets of "yes/no" radio buttons (1 for yes/ 1 for no). Do I just add each radio button as a field into the DB and if its not selected, leave it NULL (or whatever the default value is)... this does seem very efficient.

Radio Button Selection On Jquery Tabs Label Click

Jan 12, 2010

I had a simple working (ASP.NET) Scenario here: 3 asp:RadioButtons that each have OnCheckedChanged event that will update an asp:gridview. But now, I want to put some description for each radiobutton selection,and I thought it would be a good idea to embed them in JQuery UI Tabs like the following :

<div id="tabs">
<ul>
<li><a href="#tabs-1">
<asp:RadioButton ID="RadioButton1" runat="server" Text="option1" Checked="True"
AutoPostBack="True" OnCheckedChanged="RadioButton_CheckedChanged" /> </a></li>
<li><a href="#tabs-2">
<asp:RadioButton ID="RadioButton2" runat="server" Text="option2"
AutoPostBack="True" OnCheckedChanged="RadioButton_CheckedChanged" /></a></li>
<li><a href="#tabs-3">
<asp:RadioButton ID="RadioButton3" runat="server" Text="option3"
AutoPostBack="True" OnCheckedChanged="RadioButton_CheckedChanged" /></a></li>
</ul>
<div id="tabs-1"> <p> content1</p> </div>
<div id="tabs-2"> <p> content2</p> </div>
<div id="tabs-3"> <p> content3</p> </div>
</div>
and the jquery is
<script type="text/javascript">
$(function() {
$("#tabs").tabs();
});
</script>

I want the corresponding radiobuttons for each tabs be selected after switching to that tab (by clicking anywhere inside that tab) I don't know how to that probably by JQuery or JavaScript

Generated HTML source :
<div id="tabs" class="ui-tabs ui-widget ui-widget-content ui-corner-all">
<ul class="ui-tabs-nav ui-helper-reset ui-helper-clearfix ui-widget-header ui-corner-all">
<li class="ui-state-default ui-corner-top ui-tabs-selected ui-state-active"><a href="#tabs-1">
<input type="radio" checked="checked" value="RadioButtonCart" name="ctl00$ContentPlaceHolder1$g2" id="ctl00_ContentPlaceHolder1_RadioButtonCart"/><label for="ctl00_ContentPlaceHolder1_RadioButtonCart">option1</label></a></li>
<li class="ui-state-default ui-corner-top"><a href="#tabs-2">
<span style="color: Green;"><input type="radio" onclick="javascript:setTimeout('__doPostBack('ctl00$ContentPlaceHolder1$RadioButtonShetab','')', 0)" value="RadioButtonShetab" name="ctl00$ContentPlaceHolder1$g2" id="ctl00_ContentPlaceHolder1_RadioButtonShetab"/><label for="ctl00_ContentPlaceHolder1_RadioButtonShetab">option2</label></span></a></li>
<li class="ui-state-default ui-corner-top"><a href="#tabs-3">
<input type="radio" onclick="javascript:setTimeout('__doPostBack('ctl00$ContentPlaceHolder1$RadioButtonFish','')', 0)" value="RadioButtonFish" name="ctl00$ContentPlaceHolder1$g2" id="ctl00_ContentPlaceHolder1_RadioButtonFish"/><label for="ctl00_ContentPlaceHolder1_RadioButtonFish">option3</label></a></li>
</ul>
<div id="tabs-1" class="ui-tabs-panel ui-widget-content ui-corner-bottom">
<p> content1</p>
</div>
<div id="tabs-2" class="ui-tabs-panel ui-widget-content ui-corner-bottom ui-tabs-hide">
<p> content2 </p>
</div>
<div id="tabs-3" class="ui-tabs-panel ui-widget-content ui-corner-bottom ui-tabs-hide">
<p> content3 </p>
</div>
</div>

I solved 2 problems with adding ids to anchors like id="tabsA-1" and simulating the postback for

OnCheckedChanged="RadioButton_CheckedChanged" with $("#aspnetForm").submit();
<script type="text/javascript">
$(document).ready(function() {
$("#tabsA-1").click(function() {
$("#<%=RadioButtonCart.ClientID %>").attr("checked", "checked");
$("#aspnetForm").submit();
});
});
</script>

I just have to find a way to select the right tab after postback and my problem is solved.

<script type="text/javascript">
$(function() {
var $tabs = $("#tabs").tabs();
$tabs.tabs('select', '<%= selectedTabIndex %>');
});
</script>

which selectedTabIndex is a public string var in code_behind and i update its value in page_load. one funny problem was that the .tabs( 'select' , index ) in JQuery is not zero-based index of the tab as the official site said and it start from 1.

AJAX :: Textbox Postback Causing Radio Button List To Lose Selection?

May 27, 2010

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?

Forms Data Controls :: How To Pass Parameters From A GridRowView Selection Via Radio Button

Jul 21, 2010

I need to pass parameters via a gridRowView to a button I have a gridView that currently allows row selection via a radio button What I need to do is based on that selection is pass the parameters to one of 4 button options within the footer. This will then open a new page based on those values. I'd got this working using a hyperLinkButton and querystring but now I'm really struggling with the new requirement "it must be a button" selected this way

Here's my code, if it helps anyone to see it?

Javascript - Check If Selection Changed In OnClick Event?

Jul 26, 2010

Note: The answer marked as the answer, answers the questions in the Title. However, my underlying problem, using type ahead dropdowns, is solved by moving to IE8.

I have a drop down list that when I CLICK a NEW selection I want to cause a postback ("this.form.submit()") But only if the click on the dropdown list just changed the selection.

Note that OnChange will NOT work because when the selection is changed by the keyboard I would not want to postback because it is a type ahead dropdown list.

I also suppose I could use OnChange and check if the change was caused by the mouse.

Maybe if we can come up with both solutions and i'll see which works better?

EDIT: More information:

AutoPostback = true; will not work. (don't want it to post back when the selection is changed by the keyboard)

onBlur = doPostBack; I tried this, but the result is not optimal. The user has to click off the ddl after making a selection with the mouse.

Another way to state what I want to do, i think, is do a postback when both the OnChange and OnClick events fire at the same time.
