.net - Check If A Radiobutton Is Checked In A Group?
Aug 11, 2010
I have group of radio buttons, each group ranges from 5 - 27 radiobuttons. And if any radio button in a group is checked I store 1 in db else I store 0. Now I'm checking each radiobutton using if loop to see if they are checked and set database value. I'm also trying to use the code below. Is there a good/better approach to check if they are checked or not?Current code:
'rname is radiobutton prefix for a given group
'cnt is number of radiobuttons in the group
Private Function RadioIsChecked(ByVal rname As String, ByVal cnt As Integer) As Integer
[code]...

So I've got three RadioButtons, They're not in a RadioButtonList because I need to add some textboxes next to each of them.I've added a GroupName, and on the front end they behave as expected. ONLY ONE appears checked at a time.However in the code, if I do:
RadioButton1.Checked = true;
RadioButton2.Checked = true;
RadioButton3.Checked = true;
I would expect only the last one, RadioButton3, to be checked, because they all belong to the same group. This is not the case. All three evaluate to true.... how can that be?

note that the scenario is ASP.NET Webforms + Master - Content page which mess up the ids.
I have, say, three checkboxes
<asp:CheckBox ID="chkConsultantQuality" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantEnvironment" runat="server"
CssClass="company"/>
<asp:CheckBox ID="chkConsultantSafety" runat="server"
CssClass="company"/>
I would like to make a div id="CompanyPanel" on click event of each checkbox according to the following condition
visible if any of the checkboxes are checked.
hidden if all of the checkboxes are unchecked.
I am planning to use jQuery since I am selecting by class name. I could do it with jQuery.each on the class='company' by checking each for a checked flag.

I want to add the radiobutton group to the items below ( Date, txtIRID, txtShipNo) . User can only select one of them. And then this selection will be used in the button event for different handling. How to amend and add the code below?

I am using mvc3 with razor. I have a set of radiobuttons on my view
@Html.RadioButton("Status", "0", new { id = "StatusAll", @class = "selectedObjects" }) All
@Html.RadioButton("Status", "1", new { id = "StatusCurrent", @class = "selectedObjects" }) Current
@Html.RadioButton("Status", "2", new { id = "StatusDeleted", @class = "selectedObjects" }) Deleted
I would like to have "postback" to my controller (myController) and call an action (getSelected()). How would i do that?
public class MyController : Controller
{
public ActionResult Index()
{
ViewData["Status"] = 0; // show all results

I'd like to set one of a few radiobuttons to checked dynamically. They are called rbTheme1-rbTheme7. I can find them (for example the one called rbTheme3) with the code below but how do I set it to true at the loading of the page?
int buttonID = 3;
string buttonName = "rbTheme";
(RadioButton)themePick.FindControl("buttonName" + buttonID.ToString());

I've found this code, but I was wondering whether there's a more streamlined way to do it.
So for example, rather than having all the if statements can you have one line that says Label1.text = "You selected " & RadioGroup1.Text
Sub SubmitBtn_Click(Sender As Object, e As EventArgs)
If Radio1.Checked Then
Label1.Text = "You selected " & Radio1.Text
ElseIf Radio2.Checked Then

I am creating a control that inherits from the RadioButton, so that I can set the GroupName property manually. Everything is working okay apart from the fact that when the page posts back, the RadioButton becomes unchecked if it has previously been checked. This is the first time I've tried inheriting from controls, so must be doing something really silly. I would welcome anyone helping me to improve my code so that the control's Checked value persists through postbacks. I am causing a postback using a button, not the actual RadioButton itself, if that makes any difference. Here is my code:

</Columns>

<asp:Button ID="BShow" runat="server" Text="Show Data" OnClick="BShow_Click" />
1) I want to use RadioButton inside Gridview to select rows of gridview.
I tried using ASP RadioButton, but it is multi selecting the Grid rows.I want single selection of RadioButton one at a time while selecting rows.

I have a couple of RadioButtons that are created dynamically. But after postback they don't retain their checked property. I also have some CheckBoxes and they work just fine using the same mechanism (code below). I have narrowed down the problem to the "GroupName" property. If I remove it, it works just fine. But I need the RadioButtons to be mutually exclusive.

I have a radiobutton and if it is checked "Yes", then the three textboxes that are disabled in default will be enable. Now that this textboxes are enabled I want this to be mandatory. How could I do this via javascript or code behind? If I do it in code behind then autopostback is need which is unnecessary.
