Check Is A Radio Button Is Checked After Post Back?

Dec 13, 2010

I am looping through all the posted data on my website and grabbing the values, this will then be used later on. The user is going to put 2 radio buttons on the page, one with a correct answer and one with an incorrect answer. I need to know how to see if a Radio Button is checked or not based on the posted data.

Web Forms :: Multiple Radio Buttons Are Set As TRUE In Post Back?

May 9, 2010

In my code, I cannot use a radiobuttongroup due to formatting constraints. This is a page where the user can update the data. So I have

<asp:TableCell ID="TableCell1" CssClass="answer" runat="server">
<asp:RadioButton ID="PatientYes" GroupName="Patient" runat="server" />
<asp:TableCell ID="TableCell2" CssClass="answer" runat="server">
<asp:RadioButton ID="PatientNo" GroupName="Patient" runat="server" />

If I have the case where one button is set when the page is displayed and the user changes to the other value, BOTH are coming back as TRUE. How can I just get the value selected by the user?

I'm trying to add a css class to the parent div of my radio button if it is checked. Then remove if it is not checked. Using onfocus and onblur won't work on radio buttons for some reason. I also want to achieve this without specifying any type of id or name, just by the html control of 'input'.

Here's what I came up with in jquery:

Web Forms :: Radio Button Returning Null When Checked?

Apr 7, 2010

I have 3 radio buttons op1, op2, op3 working as a group. In the code behind I check to see if a paticular button is checked, then do some processing. The problem is all the buttons return null. Checked in the debugger and all values are null even op1 which value is set to true.

Front end code for the buttons are:

<asp:RadioButton ID="op1" runat="server" AutoPostBack="True" Checked="True"
GroupName="searchOPT" oncheckedchanged="op1_CheckedChanged" />
<asp:RadioButton ID="op2" runat="server" AutoPostBack="True"
GroupName="searchOPT" oncheckedchanged="op2_CheckedChanged" />
<asp:RadioButton ID="op3" runat="server" AutoPostBack="True"
GroupName="searchOPT" oncheckedchanged="op3_CheckedChanged" />

The test in the code behind is:

if (op1.Checked)
{ stuff...}
if (op3.Checked)
{ stuff...}
if (op3.Checked)
{ stuff...}

Forms Data Controls :: Radio Button In Grid View Not Getting Checked?

Mar 7, 2011

I have added a template field in a gridview. In that i have added a radio button. I have written a code which will get row Id of GridView of a row which is having a radiobutton on it checked. Through code i am getting even name of that radio button, but it is showing me that radio button is not checked, even when it is already checked. Here is the code. Dim row As GridViewRow Dim rd As RadioButton Dim rowId As Integer = -1 For Each row In GridView1.Rows rd = CType(row.FindControl("radio1"), RadioButton) If rd.Checked = True Then rowId = row.RowIndex Exit For End If Next Even when a radio button is checked the code never enters the if block.

Set Previously Selected Radio Button Checked In Classic After Page Is Postbacked?

Jun 9, 2010

I have never worked on classic ASP and unfortunately i am supposed to modify an old classisc ASP web site.

ASP.Net ViewState does take care of maintaining control's sate automatically. How do i do it in classic ASP ?

I have two radio buttons and a text box placed on my ASP page, when user types in something in the text box based on radio button selection we display different search results. Now what i need is to keep the previously selected radio button as checked after the page is postbacked. How do i do that ?

Set Value Of Radio Button Back To False?

Aug 3, 2010

Depending on what I click, true or false, this will cause my table to show or hide accordingly. My issue is, if i cancel(close) out of this while the selected is "true", and come back to this, "true" will still be selected and vice versa for "false". What I want to achieve is, regardless of the selected value, when I close out of this and come back, the selected value should alway be set to "false".

var rblRecurrence = new SelectList(new List<ListItem> {
new ListItem { Text = "Yes", Value="true" },
new ListItem { Text = "No", Value="false" }}, "Value", "Text", "false");
var htmlAttributes = new Dictionary<string, object> {
{ "onclick", "if(eval(this.value)) { $('#tblRecurrence').show('slow'); } else { $('#tblRecurrence').hide('slow'); }" }
foreach (var rbl in rblRecurrence)
<%=Html.RadioButton("rblRecurrenceVal", rbl.Value, rbl.Selected, htmlAttributes)%>

MVC :: Radio Button Sets From The Controller Without Passing 15 Different Variables To The Post Method ?

Aug 27, 2010

I'm fairly new to MVC and admittedly don't fully understand how data is passed between Views and Controllers. That said, here is my issue.

I am working with C#. I have a page which has a list of items. Each item has a radio button set of three associated with it and there are 15 of these sets on the page. Thus I have radio1, radio2....radio15, etc. Each of these has value 0, 1, or 2 upon submit. I can't seem to understand how to get the information out of these radio button sets from the controller without passing 15 different variables to the post method in the controller which is associated with the view; ie passing Int32 radio1, Int32
radio2,.., Int32 radio15, etc.

I tried using ViewData["radio"+i] in a loop to access the value of each radio button set, but this, apparently can only be used to pass data to the View from the Controller and not the other way around.

After the form is filled out, the info is then passed to an aspx page which sends out an email with the info.

C# - Using A Timer Post Back, Which Controller To Use That Doesn't Post Back To Server?

Jul 14, 2010

Being new to ASP.NET I have run into trouble building my own Whack-a-mole program. I think my problem comes from using Buttons, which by themselves send post backs to the server, making the software unusable. The looks are in place, making new buttons show up in the grid, in different places by random. However, when a button is pushed - the score doesn't change (which I feel is strange).

Not so strange is that the Button doesn't work since it sends post back to the server - reloading the UpdatePanel. I think I should use a different controller like the CheckBox and style it hard using CSS (which isn't a problem). Is this the correct way to go, or should I make use of JavaScript AJAX instead?

Note to self: This technique shouldn't be used in a public application since it put too much unwanted pressure on the web server.

Web Forms :: Disable Button After Validation But Before Post Back

Mar 29, 2010

I have orders page. When user submit Order, I need to disable the button to avoid multiple transactions. I also have few validation controls on the page, so button should not be disabled untill page is about to be posted. I dont have any custom javascript for validation. It is just these validation controls. What is the best way to achieve that? I have spend about 2 hours on google and found various solutions, but nothing seems to work. Each has some issue. On button I add OnClientClick="return btnOnClick this, 'Payment');" Below is what gets called. Unfortunately if I disable button, it cancels post back. So I am calling dopostback and also adding few lines on server side to see which button caused postback. It works fine in IE8 and Chrome. But for Firefox on server side arg comes null. Any ideas what is wrong with my code? Or any other suggestions to do it in a better way?

C# Server side
string arg = this.Request.Params.Get("__EVENTTARGET");
if (arg == "Payment") { this.ProcessPayment(); }
<asp:Button ID="btnSubmitPO" OnClientClick="return btnOnClick(this, 'Payment');" runat="server" Text="Submit Order" ValidationGroup="G" />
