Can anyone please tell about how to apply group name to html (input) radio button controls so that i can select any one of the available radio buttons?
I have input radios in a table. Each row contains two radios as follows. I want to select one from each row. But i am able to select only one radio button amongst all radio buttons present on all rows.
<input name="radiobutton" type="radio" value="radiobutton" />Option1
<input name="radiobutton" type="radio" value="radiobutton" />Option2
What change i have to make to select one radio button on each row?
Thanks,

As far as I know, radiobuttons in HTML do not have group names. Their HTML "name" attribute is the group name.
It is important to verify that each radiobutton has a unique "value" attribute. Otherwise there is no way to tell which of the duplicate values was selected:
<input name="radiobutton" type="radio" value="radiobutton1" />Option1
<input name="radiobutton" type="radio" value="radiobutton2" />Option2
This example lets you choose only one radio button per table row. You have to give all radio buttons the same Name= to create a mutually exclusive group of them.
<form>
<table>
<tr><td>
<!-- Can choose only one of these two. -->
<input name="group1" type="radio" value="1a" />Option1
<input name="group1" type="radio" value="1b" />Option2
</td></tr>
<tr><td>
<!-- Can choose only one of these two. -->
<input name="group2" type="radio" value="2a" />Option1
<input name="group2" type="radio" value="2b" />Option2
</td></tr>
</table>
</form>

I have some radio buttons. But I also want to the text clickable. So that the ratio button is selected. So not only if you click on the radio button that the ratio buttion is selected, but also if you click on the text, that the ratio button is selected.
I have this:
<td>
<input id="upload" name="folder" type="radio" value="#item" />
<label>#Html.Label(item)</label>
</td>
Thank you
I try it like this:
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<table>
#foreach (var item in Model.Directories)
{
<tr>
<td>
<input id="upload" name="folder" type="radio" value="#item" />
<label for="upload">#Html.Label(item)</label>
</td>
</tr>
}
</table>
</div>
</div>
I have it now like this:
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<table>
#foreach (var item in Model.Directories)
{
<tr>
<td>
<label>
<input type="radio" name="folder" value="#item" id="upload">
<label for="folder">#Html.Label(item)</label>
</label>
</td>
</tr>
}
</table>
</div>
</div>
but the radio buttons are in a foreach loop, so the id is different of every radio button
I try it like this:
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<table>
#foreach (var item in Model.Directories)
{
#for(var i=0; i < item.Count; i++){
<tr>
<td>
<fieldset>
<input type="radio" name="folder" value="#item" id="folder">
<label for="folder">#Html.Label(item)</label>
</fieldset>
</td>
</tr>
}
}
</table>
</div>
</div>
You can use for attribute with the value of the input's id attribute:
<input id="upload" name="folder" type="radio" value="#item" />
<label for="upload">#Html.Label(item)</label>
the simple way
<td>
<label>
<input id="upload" name="folder" type="radio" value="#item" />
#Html.Label(item)</label>
</td>
use label for
<td>
<input id="upload" name="folder" type="radio" value="#item" />
<label for="upload">#Html.Label(item)</label>
</td>
Using for attribute:
<label for="folder">#Html.Label(item)</label>
You need to enclose the radio within a label tag, To display some text add a tag inside the label:
<label for="upload">
<span>#Html.Label(item)</span>
</label>
<input type="radio" name="folder" value="#item" id="upload" >
I have a nested textbox inside a radiobuttom list item
here is the code
<asp:RadioButtonList ID="OtherEducInNursing" runat="server" RepeatColumns="1" RepeatDirection="Vertical" RepeatLayout="Table">
<asp:ListItem Value="1">Certificate<input id="OtherEdNsgCertName" type="text" MaxLength="25"/></asp:ListItem>
<asp:ListItem Value="2">Baccalaureate</asp:ListItem>
<asp:ListItem Value="3">Master</asp:ListItem>
<asp:ListItem Value="4">Doctorate</asp:ListItem>
<asp:ListItem Value="5">None of the above</asp:ListItem></asp:RadioButtonList>
It works fine both in chrome, but in firefox, when i tried to click the textbox, the blinking cursor loses focus, I have to click the text box couple times to get cursor back
I added some code like this
onclick="document.getElementById('OtherEdNsgCertName').focus();"
which still didn't work, doesn anyone know why and how to fix it? thanks very much
edit
here is the jquery code too
$(document).ready(function () {
if($("#<%=OtherEducInNursing.ClientID%> :checked").val()!="1")
$("#OtherEdNsgCertName").hide();
else
$("#OtherEdNsgCertName").show();
$("#<%=OtherEducInNursing.ClientID%>").click(function () {
if($("#<%=OtherEducInNursing.ClientID%> :checked").val()!="1")
$("#OtherEdNsgCertName").hide();
else
$("#OtherEdNsgCertName").show();
});
edit：
html code:
<table id="MainPlaceHolder_OtherEducation_OtherEducInNursing">
<tbody><tr>
<td><input type="radio" value="1" name="ctl00$MainPlaceHolder$OtherEducation$OtherEducInNursing" id="MainPlaceHolder_OtherEducation_OtherEducInNursing_0"><label for="MainPlaceHolder_OtherEducation_OtherEducInNursing_0">Certificate<input type="text" onclick="document.getElementById('OtherEdNsgCertName').focus();" maxlength="25" id="OtherEdNsgCertName"></label></td>
</tr><tr>
<td><input type="radio" value="2" name="ctl00$MainPlaceHolder$OtherEducation$OtherEducInNursing" id="MainPlaceHolder_OtherEducation_OtherEducInNursing_1"><label for="MainPlaceHolder_OtherEducation_OtherEducInNursing_1">Baccalaureate</label></td>
</tr><tr>
<td><input type="radio" value="3" name="ctl00$MainPlaceHolder$OtherEducation$OtherEducInNursing" id="MainPlaceHolder_OtherEducation_OtherEducInNursing_2"><label for="MainPlaceHolder_OtherEducation_OtherEducInNursing_2">Master</label></td>
</tr><tr>
<td><input type="radio" value="4" name="ctl00$MainPlaceHolder$OtherEducation$OtherEducInNursing" id="MainPlaceHolder_OtherEducation_OtherEducInNursing_3"><label for="MainPlaceHolder_OtherEducation_OtherEducInNursing_3">Doctorate</label></td>
</tr><tr>

</tr>
Remove the focus function from the textbox and give focus in your jQuery:
$(document).ready(function () {
if($("#<%=OtherEducInNursing.ClientID%> :checked").val()!="1")
$("#OtherEdNsgCertName").hide();
else
{
$("#OtherEdNsgCertName").show();
$("#OtherEdNsgCertName").focus();
}
$("#<%=OtherEducInNursing.ClientID%>").click(function () {
if($("#<%=OtherEducInNursing.ClientID%> :checked").val()!="1")
$("#OtherEdNsgCertName").hide();
else
{
$("#OtherEdNsgCertName").show();
$("#OtherEdNsgCertName").focus();
}
});
ok, i have this:
<div class="radio-toolbar">
<input type="checkbox" id="check1" name="checks" value="1">
<label for="check1">1</label>
<input type="checkbox" id="check2" name="checks" value="2">
<label for="check2">2</label>
<input type="checkbox" id="check3" name="checks" value="3">
<label for="check3">3</label>
</div>
and i'm looking for a way to set the "onclick" attribute of those labels with ASP.NET VB Codebehind, making the labels looks like:
<div class="radio-toolbar">
<input type="checkbox" id="check1" name="checks" value="1">
<label for="check1" onclick="some javascript">1</label>
<input type="checkbox" id="check2" name="checks" value="2">
<label for="check2" onclick="some javascript">2</label>
<input type="checkbox" id="check3" name="checks" value="3">
<label for="check3" onclick="some javascript">3</label>
</div>
so, is that possible?
Use a asp:Label.
<asp:Label ID="lblChk1" runat="server" AssociatedControlID="check1" Text="1">
</asp:Label>
Then in your code behind:
lblChk1.Attributes.Add("onclick","some javascript");
Edit: You could simply use asp:CheckBox and use its Text Property. Clicking the text would then fire the onclick event of your CheckBox.
Set the ID attribute and add runat=server for your labels. Then you can access the labels from your code-behind:
<div class="radio-toolbar">
<input type="checkbox" id="check1" name="checks" value="1">
<label ID="label1" runat="server" for="check1">1</label>
<input type="checkbox" id="check2" name="checks" value="2">
<label ID="label2" runat="server" for="check2">2</label>
<input type="checkbox" id="check3" name="checks" value="3">
<label ID="label2" runat="server" for="check3">3</label>
</div>
Instead of a html label i would use the ASP.NET Label control with AssociatedControlID attribute which is rendered as label for.
<asp:Label ID="Label1"
AssociatedControlID="check1"
onclick="somejavascript"
runat="server"
Text="1"></asp:Label>
You can also add the javascript from codebehind:
Label1.Attributes.Add("onclick","somejavascript");
From MSDN:
...
When the AssociatedControlID property is set, the Label control
renders as an HTML label element, with the for attribute set to the ID
property of the associated control. You can set other attributes of
the label element using the Label properties. For example, you can use
the Text and AccessKey properties to provide the caption and hot key
for an associated control.

If I have the following CheckBoxList
<asp:CheckBoxList ID="typeCheckBoxList" runat="server" RepeatDirection="Horizontal">
<asp:ListItem Value="0">Student</asp:ListItem>
<asp:ListItem Value="1">Parent</asp:ListItem>
<asp:ListItem Value="2">Educational</asp:ListItem>
<asp:ListItem Value="3">Specialist </asp:ListItem>
<asp:ListItem Value="5">Other</asp:ListItem>
</asp:CheckBoxList>
Using Jquery i want to get the values of the selected items, I use the following code
$('#<%= typeCheckBoxList.ClientID %> input:checked').each(function() {
alert($(this).val());
alert($(this).next('label').text());
});
$(this).val() always returns "on" and I can't return values such as 0 ,1, etc.
Is there any way to do that ?
EDIT : Rendered Markup:
<table id="RegisterationWUC1_typeCheckBoxList" class="listVertical" border="0">
<tr>
<td>
<input id="RegisterationWUC1_typeCheckBoxList_0" type="checkbox" name="RegisterationWUC1$typeCheckBoxList$0" />
<label for="RegisterationWUC1_typeCheckBoxList_0">Student</label>
</td>
<td>
<input id="RegisterationWUC1_typeCheckBoxList_1" type="checkbox" name="RegisterationWUC1$typeCheckBoxList$1" />
<label for="RegisterationWUC1_typeCheckBoxList_1">Parent</label>
</td>
<td>
<input id="RegisterationWUC1_typeCheckBoxList_2" type="checkbox" name="RegisterationWUC1$typeCheckBoxList$2" />
<label for="RegisterationWUC1_typeCheckBoxList_2">Educational</label>
</td>
<td>
<input id="RegisterationWUC1_typeCheckBoxList_3" type="checkbox" name="RegisterationWUC1$typeCheckBoxList$3" />
<label for="RegisterationWUC1_typeCheckBoxList_3">Specialist </label>
</td>
<td>
<input id="RegisterationWUC1_typeCheckBoxList_4" type="checkbox" name="RegisterationWUC1$typeCheckBoxList$4" />
<label for="RegisterationWUC1_typeCheckBoxList_4">other</label>
</td>
</tr>
</table>
Since ASP.Net 2.0 doesn't render this appropriately (it's intended purpose is to get the values server-side) you can do a bit of hackery. In the code-behind, do something like this:
foreach (ListItem li in typeCheckBoxList.Items)
li.Attributes.Add("data-value", li.Value);
Then your markup will look like this (ignore the shorter names, my test wasn't in another named container, and it doesn't matter one bit for the question at hand):
<table id="typeCheckBoxList">
<tr>
<td>
<span data-value="0">
<input id="typeCheckBoxList_0" type="checkbox" name="H$M$typeCheckBoxList$0" />
<label for="typeCheckBoxList_0">Student</label>
</span>
</td>
<td>
<span data-value="1">
<input id="typeCheckBoxList_1" type="checkbox" name="H$M$typeCheckBoxList$1" />
<label for="typeCheckBoxList_1">Parent</label>
</span>
</td>
<td>
<span data-value="2">
<input id="typeCheckBoxList_2" type="checkbox" name="H$M$typeCheckBoxList$2" />
<label for="typeCheckBoxList_2">Educational</label>
</span>
</td>
<td>
<span data-value="3">
<input id="typeCheckBoxList_3" type="checkbox" name="H$M$typeCheckBoxList$3" />
<label for="typeCheckBoxList_3">Specialist </label>
</span>
</td>
<td>
<span data-value="5">
<input id="typeCheckBoxList_4" type="checkbox" name="H$M$typeCheckBoxList$4" />
<label for="typeCheckBoxList_4">Other</label>
</span>
</td>
</tr>
</table>
Notice that extra <span data-value="valueHere"></span> wrapped around it now? You can just use .closest() or .parent() to get to the <span> and retrieve that value via .attr(), like this:
$('#typeCheckBoxList input:checked').each(function() {
alert($(this).closest('span').attr('data-value'));
alert($(this).next('label').text());
});
Give it a try in a demo here :) If it helps at all. the default rendering mode for ASP.Net 4.0 does render the value in markup, as it should. The reason for the data-thing format on the attribute is to be as valid as possible, these are called data attributes, added to the spec in HTML5, but cause no issues for this in 4.
I use the RepeatColumns of an ASP CheckBoxList to create three columns in a list of genres. This usually works OK but occasionally when the page loads the columns collapse. This seems to happen randomly and across all browsers. I do use OutputCache.
Has anyone noticed this behavior before?
This is a snippet of the code:
<table width="100%"><tr><td width="66%" style="padding-left:4px">Genres:</br>
<asp:CheckBoxList RepeatColumns="3" CssClass="chkChoice" ID="CheckBoxList_Genres" runat="server">
<asp:ListItem Selected="True">Action</asp:ListItem>
<asp:ListItem Selected="True">Comedy</asp:ListItem>
<asp:ListItem Selected="True">Classics</asp:ListItem>
<asp:ListItem Selected="True">Documentary</asp:ListItem>
<asp:ListItem Selected="True">Drama</asp:ListItem>
<asp:ListItem Selected="True">Fantasy</asp:ListItem>
<asp:ListItem Selected="True">Foreign</asp:ListItem>
<asp:ListItem Selected="True">Independent</asp:ListItem>
<asp:ListItem Selected="True">Kids</asp:ListItem>
</asp:CheckBoxList>
</td>
In response to the comment, this is the rendered html:
<span id="ctl00_ContentPlaceHolder1_CheckBoxList_Genres" class="chkChoice"><input id="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_0" type="checkbox" name="ctl00$ContentPlaceHolder1$CheckBoxList_Genres$0" checked="checked" /><label for="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_0">Action</label><input id="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_3" type="checkbox" name="ctl00$ContentPlaceHolder1$CheckBoxList_Genres$3" checked="checked" /><label for="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_3">Documentary</label><input id="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_6" type="checkbox" name="ctl00$ContentPlaceHolder1$CheckBoxList_Genres$6" checked="checked" /><label for="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_6">Foreign</label><br /><input id="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_1" type="checkbox" name="ctl00$ContentPlaceHolder1$CheckBoxList_Genres$1" checked="checked" /><label for="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_1">Comedy</label><input id="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_4" type="checkbox" name="ctl00$ContentPlaceHolder1$CheckBoxList_Genres$4" checked="checked" /><label for="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_4">Drama</label><input id="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_7" type="checkbox" name="ctl00$ContentPlaceHolder1$CheckBoxList_Genres$7" checked="checked" /><label for="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_7">Independent</label><br /><input id="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_2" type="checkbox" name="ctl00$ContentPlaceHolder1$CheckBoxList_Genres$2" checked="checked" /><label for="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_2">Classics</label><input id="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_5" type="checkbox" name="ctl00$ContentPlaceHolder1$CheckBoxList_Genres$5" checked="checked" /><label for="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_5">Fantasy</label><input id="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_8" type="checkbox" name="ctl00$ContentPlaceHolder1$CheckBoxList_Genres$8" checked="checked" /><label for="ctl00_ContentPlaceHolder1_CheckBoxList_Genres_8">Kids</label></span>
If you do not mind tabulating the checkboxlist, add RepeatLayout="Table".
E.g.
<asp:CheckBoxList RepeatColumns="3" CssClass="chkChoice"
ID="CheckBoxList_Genres" runat="server"
RepeatLayout="Table" >....
