Working on VS2008 with using .vb
I have placed two radiobutton's on simple .aspx page. I didn't used any Update Panel or any javascript on that page also set both radiobutton's AutoPostback="True", But it's not responding as I want.
I have a web application that shows a page containing between 6 and 20 AJAX UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here:
[URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button
clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)
Not sure if this is an AJAX issue, or general ASP.NET UI issue, so I'm posting in two forums on this one.
I need to create dynamic radio buttons in my page, and then access their values in postback
I create the buttons using the following code:
[Code]....
In the post back I try to access the radio buttons using their created ID:
[Code]....
But it seems that the find method is never finding the Radio button control.
I am having a bit of trouble trying to get teh postback data from a programmatic generated radio buttons in TableCell object. I have the following ASP user control:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="wcntrlCallFlow.ascx.cs" Inherits="CallEvaluation.wcntrlCallFlow" %>
<style type="text/css">
.TableDev
{
width: 100%;
border-style: solid;
border-width: 1px;
border-color: Black;
}
.HeaderRowStyle
{
width: 100%;
border-style: solid;
border-width: 1px;
border-color: Black;
background-color:#33CCCC;
}
.DetailRowStyle
{
width: 100%;
border-style: solid;
border-width: 1px;
border-color: Black;
background-color:White;
}
</style>
<asp:Table ID="tblControl" runat="server"/>
I generate the TableRow and TableCell base off XML data file. When the submit occurs I can not access the data values from the radio buttons that are generated. I try to get the data in the following manner:
if(Request[objRadioName].Checked)
{
this.value = 5;
this.ReCalc();
}
I notice that in the Request object the table row name is passed back like: "wcntrlCallData1$wcntrlCallFlow1$CallFlow".
i have a table which looks something like the following
<table id="Table1" border="0">
<tr>
<td><b>1.</b> Question 1</td>[code]....
how do i go about looping through each group of radio buttons and getting the text of the selected radio button ?the code displayed above is created dynamically ... in my aspx file i have the following code
<asp:Table ID="Table1" runat="server">
</asp:Table>
In my form i have three radio buttons and nine image buttons, three image buttons per radio buttons
If the user check one radio button, the respective three image buttons only has to be displayed.
In a single time one radio button only can be checked the rest two would be unchecked
Here i have pasted the aspx file design source

How to use radio buttons with example is ther any good article related to this in mvc mobile?
View 1 RepliesI've got 3 groups of controls each of which I want enabled/disabled depending on which radio button the user has clicked.
The code *works*, but daaaaaayuum the postback time from a radiobutton click is long.
I suspect my approach is the noobish way, and that there's a slicker way to achieve this control-groups-enabled effect.
How can I bind radio buttons to an sqldatasource for update ?
View 2 RepliesI have the following client side code in .aspx page within a datalist itemtemplate that takes questions from the database like this:
[Code]....
The output is like:
1) What is your age group?
- Option 1
- Option 2
- Option 3
- Option 4
The ID's of the radio buttons are dynamic ("Q" & QuestionID). If there is no answer to a question then the GetVisible function returns false and the containing panel is hidden.
I have been trying to get rid of the html and replace these with asp:radiobuttons but it is not possible to set id's from databinding.. only simply. I was trying something like:
<asp:RadioButton ID="Q<%#Eval("ID")%>" runat="server" Visible='<%#GetVisible(Eval("OptionA").Tostring())%>'
Text='<%#Server.HtmlEncode(Eval("OptionA").ToString())%>' />
Here is the function that provides data:
[Code]....
but I'm finding it impossible to work with the html controls, i.e get their .text value from codebehind, or adding events!
better way to replace the html with suitable asp.net web controls or from the codebehind and output it. Or point me in the right direction?
I have a table, that contains a number of rows, in each row there are three columns that are mutually exclusive. What I need is to be able to have radio buttons that are linked across the three columns.

I'd like for where there is a 1 for it to display a checked radio button, and where there is a 0 for it to be unchecked. This can then be edited by clicking the radio in another column where necessary.
I have a formview that runs of an SQLDS, very simple stuff. Inside that form i have various fields, one of them is a credit field, one of them is a debit field. Now i have put a radio button list with two radio buttons (credit and debit). What i want to do is when the "credit" radio button is enabled i want the "credit" text box to be enabled and visa versa.
I know how to reference an object inside a formview, but i am confused, do i reference the radio button list and then the list items inside it or?
"Radio Buttons Are Not Mutually Exclusive When Used in a Repeater" according to KB #316495 http://support.microsoft.com/kb/316495. This bug also exists with ListViews, and I am having a hard time developing a workaround. Is there a solution or workaround available? I'm using Visual Studio 2010.
(Here is my ASPX. I want rbGroupedSession and rbFees to be mutually exclusive. Databinding and setting controls visible attribute to true/false is done in the code-behind. I'm also setting the RadioButtons "GroupName" property correctly in the code-behind, but it gets changed when rendered in the browser -- which is bug KB #316495)..

I've got a gridview that will allow clients to edit options they've already entered on another page. The gridview has three radio buttons in it each with a value of 1,2,3. The option value in the dataset is 1,2 or 3 respectively. I would like to have the radiobutton with the corresponding value selected in the gridview so they can see what they previously chose and will then be able to edit, if they wish.
Here's my code so far:

View 3 RepliesI have a 2 groups of Radio Button controls on my web page that are dynamically loaded. They are contained within a DataList control. I have the "GroupName" property set for each of the groups, however, I am still able to click on more than one rdo within each group. I've set the "GroupName" property within my HTML markup.
View 8 Repliesis it possible to dynamically create radio button options that are dependent on a value within a database? For example 'b' is stored in a field so then 'a' will also be a radio button option, 'd' is stored in a database field so then the other radio button options will be 'a', 'b', 'c'....the radio button list will change depending on the value stored in the database field.
View 1 RepliesI am using Radio buttons inside a panel in a web page. (Since group boxes are not there). But when I click on each radio button they all are checked. They are not acting as a group but single units.
View 3 RepliesI'm trying to implement accessibility (keyboard only) ability on my site, but I'm having problems with Radio Button lists. When using radiobuttonlists, when initially, none of the radio buttons is selected, I am able to tab through every single value and select one upon hitting "enter". However, after a value is selected, I can only tab to the selected values, which presents a problem if I want to change the selected value.
From what I understand, radio buttons are grouped at the container controller level, thus when it is considered a group, only one can be selected at a time.
I am dynamically creating radio button within code behind in ASP.Net, how do I add the controls so they appear vertically instead of horizontally?

I am having a problem with setting up radio buttons within a datalist, ive never done this and i know they require unque names.
It is to be 4 radio buttons per question where only one can be select, i know how to group just not via a datalist with unique names
I have a set of radio buttons (individual buttons) in asp.net. These buttons have a group name (if that matters). What I need to happen is, anytime a user selects a radio button, I need some jQuery to be called. I am not doing a page refresh when the user selects the radio button, so I need this to be done on the fly. I have tried a "CheckedChanged" event in asp.net and can not get it to fire. I have also tried:
if ($('input:radio').attr('checked') === true) {
var checked = $('input:radio:checked').val();
}
however it only works the first time the page is loaded, not when a user selects something other than the default. What Can I do to fix this?
