Hi,
Is there any possible way to unselect a number of radiobuttons grouped in the same groupname?
Thank you
Jump to PostI use another radio button
<input type='radio' value="1" name="samename" >5<br> <input type='radio' value="2" name="samename" >4<br> <input type='radio' value="3" name="samename" >3<br> <input type='radio' value="4" name="samename" >2<br> <input type='radio' value="5" name="samename" >1<br> <input type='radio' value="" name="samename" checked>Reset<br>
Jump to Postsorry, can you explain more please?
look at the html sample given, copy it to a html file on your desktop and run it
the reset button will uncheck any other button in the list
and give a nul value, so that verification of submitted data can still take place
Jump to Postthat has little relation to the question first asked,
stipulated same groupname,
gone to examine some code,
post when i have an answer

There is no button in your code ! Maybe you're talking about the reset radiobutton.
What I'm looking for is the following:
I have 2 groupnames, each one has many radiobuttons. When I select a radiobutton from the 1st groupname (group1), it must unselect all radiobuttons in the 2nd groupname (group2). I tried this code but it's not working
foreach (RadioButton btn in this.Controls)
{
//Do some commands
}
Also I tried this but it's not working
protected void Button1_Click(object sender, EventArgs e)
{
//http://www.experts-exchange.com/Programming/Languages/.NET/ASP.NET/Q_20987249.html
foreach (Control btn in this.Controls)
{
if (btn is System.Web.UI.WebControls.RadioButton)
{
//Do some commands
//TextBox1.Text += ((RadioButton)btn).Text + "<br>";
}
}
foreach (RadioButton btn in this.Controls)
{
//Do some commands
}
}
that has little relation to the question first asked,
stipulated same groupname,

Try this javascript function to uncheck all radiobuttons with the same groupname.
function unSelectAllCheckBoxes()
{
var rdoBtns_Array = document.getElementsByTagName('input');
if(rdoBtns_Array.length>0)
{
for(i=0; i<rdoBtns_Array.length; i++)
{
//Check for radio button with groupname 'myGroupName'
if((rdoBtns_Array[i].type == 'radio') && (rdoBtns_Array[i].name == 'myGroupName'))
{
//Uncheck Radio Button
rdoBtns_Array[i].checked = false;
}
}
}
}
Thank you Aneesh_Argent.

Your answer confirm that it's impossible to unselect a given group of radiobuttons in a single instruction (like ClearSelection() of the RadioButtonList) !
I'm not familiar to Javascript. I'm newbie to aspx. At the moment, this solution is working for me:
protected void RadioButton_CheckedChanged(string groupname, string buttonlistname)
{
foreach (Control ctrl in form1.Controls)
{
if (ctrl is System.Web.UI.WebControls.RadioButton)
{
RadioButton btn = (RadioButton)ctrl;
if (btn.GroupName != groupname)
btn.Checked = false;
}
else if (ctrl is System.Web.UI.WebControls.RadioButtonList)
{
RadioButtonList btn = (RadioButtonList)ctrl;
if (btn.ID != buttonlistname)
btn.ClearSelection();
}
}
}
and I'm calling this function from any RadioButton or RadioButtonList Checked Changed as follows:
protected void RadioButton2_CheckedChanged(object sender, EventArgs e)
{
RadioButton_CheckedChanged(RadioButton2.GroupName, "none");
}
protected void RadioButton3_CheckedChanged(object sender, EventArgs e)
{
RadioButton_CheckedChanged(RadioButton3.GroupName, "none");
}
...
protected void RadioButtonList1_SelectedIndexChanged(object sender, EventArgs e)
{
RadioButton_CheckedChanged("none", RadioButtonList1.ID);
}
Thank you almostbob
that has little relation to the question first asked,
Maybe, but i was looking for an instruction that may permit the unselection of a number of groupnames, without using the foreach ALL CONTROLS.
one group precludes the other
is it possible to use a single name and divide the response to the buttons by group, at form validation
example perhaps
ignoring syntax punctuation and styling, trying something brain not 100%
<table><tr>
<td>
<input type=radio name=groupname value=A1>a1
<input type=radio name=groupname value=A2>a2
<input type=radio name=groupname value=A3>a3
<input type=radio name=groupname value=A4>a4
<input type=radio name=groupname value=A5>a5
<input type=radio name=groupname value=A6>a6
</td><td>
<input type=radio name=groupname value=b1>B1
<input type=radio name=groupname value=b2>B2
<input type=radio name=groupname value=b3>B3
<input type=radio name=groupname value=b4>B4
<input type=radio name=groupname value=b5>B5
<input type=radio name=groupname value=b6>B6
<input type=radio name=groupname value=b7>B7
</td></tr></table>
when the form is submitted parse the response by first character, if (function defined elsewhere) firstchar = b do something
if (function defined elsewhere) firstchar = a do something different
any response in group B unchecks all responses in group A
any response in group A unchecks all in group B
another option
after radio buttons are selected there is no way to unselect them all, a hidden nul value button may work if the forms cannot share a name and be poarsed on validation
please igonre syntax errors,
as the first radio button in a group
<input type=radio style='visibility:hidden' name=groupa value=">
<input type=radio name='groupa' onselect="document.groupb[0].checked;" value='a1>a1
<input type=radio name='groupa' onselect="document.groupb[0].checked;" value='a2>a2
<input type=radio name='groupa' onselect="document.groupb[0].checked;" value='a3>a3
buttons in group.b
<input type=radio style='visibility:hidden' name=groupb value="">
<input type=radio name='groupb' onselect="document.groupa[0].checked;" value='B1>B1
<input type=radio name='groupb' onselect="document.groupa[0].checked;" value='B2>B2
<input type=radio name='groupb' onselect="document.groupa[0].checked;" value='B3>B3
still not 'good' ideas
onselect="document.groupa[0].checked;"
onselect="document.groupa[0].checked=true;"
getting sloppy
sorry
You can also add the input button (btnDeleteSelection) and use this javascript code to deselect all items in radio button list:
$("#btnDeleteSelection").click(function() {
$('#<%=radioButtonList.ClientID %> input[type=radio]:checked').removeAttr("checked");
return false;
});
