Feb 24, 2010A new route to an old problem for me... I'm creating radiobuttonlists and adding them to an update panel dynamically using this code:

I'm wanting to get the selected radio button value whenever a button on the page is pressed, however (and this is my old problem) I cannot retrieve that value. What I'm wanting to try is to add an event that will record the chosen radio button whenever the selected value has changed and store it into an array.

On the save button event i want to access the data of the row and save the data in DB with which ever radio button is selected.I tried different things but all in vain.

Get Value Of Dynamically Created Radiobuttonlist?
May 24, 2010I'm trying to get the value of a dynamically created radiobuttonlist via javascript to call a pagemethod.
This is how I'm creating the rbl:
rbl.Attributes["onclick"] = "javascript:preview('" + rbl.ID + "','" + rbl.ClientID + "');";
And this is the javascript:
function preview(controlid, clientid)
{
var radio = document.getElementsByName(clientid);
var answer = "k";
for (var ii = 0; ii < radio.length; ii++)
{
if (radio[ii].checked)
answer = radio[ii].value;
}
PageMethods.SaveAnswer(controlid, answer);
}
The problem however is that I want to get the groupname of the radiobuttionlist so I can use getElementsByName, but i have no luck so far.

Dynamically Generate Multiple RadioButtonList And Capture Their Values?
Oct 12, 2010I have a situation where I need to generate multiple sets of radio buttons. These radio buttons display One to Many relationship data.
I know how to get it to work with a workaround that I used back in Classic ASP days ... in which I essentially just spit out the HTML dynamically and keep track of my controls using systematic IDs. Which is nothing more then an Primary Key appended to a string constant i.e. String.Format("Dynamic_{0}", myChildRecordPKValue) so my HTML looks like this:
[Code]....
Note that I am using a javascript function which updates a hidden field with the selected value (Each parent record has a corresponding hidden field). So after making selection user will hit the submit button and I get my values using Request.Form[myHiddenField1] and so on ...

Jun 10, 2010I have a radiobuttonlist control on my control, where the datasource is a collection, and I am using the DataTextFormatString to set the text field to a hyperlink. All this bit works, but where I am struggling to work is to add to the url path the value from the datavaluefield. Nothing I try works! Does anyone know how to set the datavaluefield into the url? Further, and one last question, my radiobuttonlist control is in a wizard step, and when the user clicks on a hyperlink, I want it to go on to the next step, all that is happening is that the link is going back to the first step.

Dec 23, 2013I have added a RadioButtonList inside a repeater as follows:
(.aspx file):
<asp:Button ID="Button1" Text="Add Comment" runat="server" />
<asp:Panel ID="pnlPanelDemo" runat="server" CssClass="modalPopup" ViewStateMode="Disabled">

Now suppose if 3 questions are displayed on the webpage then 3 radiobuttonlists are displayed. I need to send the selected text of radiobuttons separately in my table in SQL Server on a button click event.
Suppose if selected answers are Very Poor, Average and Good then database entry should look like:

2Â Â Â Â Â Â Â Â Average
3Â Â Â Â Â Â Â Â Good

Web Forms :: DropDownlist Selecteditem Not Updateing?
Mar 29, 2011I have a dropdownlist in a Usercontrol defined in a table as:
<asp:DropDownList
runat="server"
id="lstDIDFCM"
Width="135px"
AutoPostBack="true"
></asp:DropDownList>
i have the AutoEventWireup="True"; I have a breakpoint in the code behind on the SelectedIndexChange event.
The event does fire but the index is not changing. No matter what item in the list I select, the SelectedIndex always = 0. The list is bound to a dataset and the DataTextField and DataValueField are both set to the same value. Why is the index and SelectedValue not updating?
Web Forms :: FindControl SelectedItem In Dynamic DropDownList
Jun 5, 2010 First post here, I usually try not posting until I am completely lost. I have a webform that gets a dynamic dropdownlist added to a placeholder in a method during pageload. During a submit of the page, I want to be able to get the selectedItem in the DropDownList that was also added dynamically from a DB. I know the ID of the DropDownList, and I know the Value of all the ListItems. Although when I am trying to use FindConrol(ID), and assign it to a DropDownList, the Control comes back Null and I get an error saying "Object Reference not set to and Instance of an Object", I believe because its not finding the control.
[Code]....
Can anyone show me how to use this to get access to the properties of the dynamic DropDownList properties, especially the ListItems within.
Forms Data Controls :: How To ListView SelectedItem SelectedItemChanged
Apr 11, 2010I give up. After many hours of scouring the internet, cannot find a simple example of binding a simple object to a ListView and figure out which one is selected in the SelectedIndexChanged event.
Many people talk about the SelectedItem and SelectedItems properties; which somehow, according to intellesense, do not even exist on my ListView. I must have a "special .Net build" :)
If I have a collection of "Books" bound to a ListView. How do I get the "selected book" in the SelectedIndexChanged event? (Multiselect = false)
I would think it's something like:
Book MyBook = (Book)ListView1.SelectedItem
I'd even settle for
Book MyBook = (Book)ListView1.SelectedItems[0]
No such luck. My very special ListView does not seem to have either property.
