Web Forms :: Add Eventhandler To Radiobuttonlist Dynamically To Retrieve Selected Value?
Feb 24, 2010
A new route to an old problem for me... I'm creating radiobuttonlists and adding them to an update panel dynamically using this code:
[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.

How can I get the selected value of a radioButtonList if this is created dynamically? I know that a dynamic control must be recreated on each postback but, is there a trick to solve this scenario?

the database has two columns one for questions and the other is for choices , for the first question with id lets say 1 there are 4 choices, when the radiobutton is binded the result appears to be 4 times duplicated ?

I am banging my head with gridview at the moment. There's a problem I just can't get my head around. I'd be very greatful for any advice given. I have a function that creates a DataTable with three columns and four rows. In each of the cells I set the text to a random number through RowDataBound event. I would like to just make the cell clickable and have a code-behind function that gets the position of the cell (column, row) and the value of the cell when the user clicks it.

The scenerio is I have a UserControl. This user control will create dynamically ListBoxes if the given List's count > 0. The controls are adding dynamically, there is no problem with adding them, but the event handler is not adding. If I select an item in first listBox, the secondListBox will be added dynamically, and items will add dynamically too. First listBox appears, but the selectedIndexChanged event handler doesn't work. What can be the problem with my code?
EDIT: I tried to add
li.Attributes.Add("onselectedindexchanged","selectedIndexChanged");
or
li.AutoPostBack = true;
but still not firing...
private List<string> myList = new List<string>() { "Serkan", "Kadir" };
private List<string> mySecondList = new List<string>() { "Istanbul", "Ankara" };
protected void Page_Load(object sender, EventArgs e)

I´m using a Repeater to generate Items out of a Database. Each ReapeaterItem should include an UpdatePanel, because i have to Update the Controls inside the UpdatePanel and do not want to reload the complete page. Inside these dynamically generated UpdatePanels (each RepeaterItem has one) i´m adding up to three Checkboxes dynamically (based on the Database). These Checkboxes need to fire the "CheckedChanged" event, because on some conditions i want to enable/disable/check/uncheck Checkbox1, 2 or 3 based on business logic. ... Hope you got this so far. I´m adding all Controls and have the EventHandler Added. But the generated Code does not reflect the Event Handler. I tried OnItemDataBound, OnItemCreated, PreRender, ... Events to add the Eventhandler too, but i was not able to find the CheckBox-Control with the ID.
I´m totally lost with this and on the way to use Buttons instead of Checkboxes. From what i read so far is that with Buttons i can use the CommandName from the Button and the ItemCommand-Event from the Repeater to get a workaround, but then i need to reflect the "Check" on the Page in some way. btw, every Repeater (8) sits inside an ajaxtoolkit-accordion control. Here i give you some Code:
aspx-Page
<asp:Repeater ID="RepeaterAccordionPane2" runat="server">
<ItemTemplate>
HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Header")%>HTML Stuff<%# DataBinder.Eval(Container.DataItem, "Beschreibung")%></td>
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode=Conditional>
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
HTML Stuff
</ItemTemplate>
</asp:Repeater>
Here is the Page_Load Part
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dvAlleArtikel = new System.Data.DataView(...Database...);
[... some other code here ...]
RepeaterAccordionPane2.DataSource = dvAlleArtikel;
//RepeaterAccordionPane2.ItemCreated +=new RepeaterItemEventHandler(RepeaterAccordionPane2_ItemCreated);
//RepeaterAccordionPane2.PreRender +=new EventHandler(RepeaterAccordionPane2_PreRender);
RepeaterAccordionPane2.DataBind();
int nUpdatePanelIndex = 0;
foreach (Control crInRepeater in RepeaterAccordionPane2.Controls)
{
if (crInRepeater.GetType() == typeof(RepeaterItem))
{
foreach (Control crInRepeaterItem in crInRepeater.Controls)............

how to get Radiobuttonlist selected value in a repeater

I 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">
<cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</cc1:ToolkitScriptManager>
<asp:Repeater ID="rptComments" runat="server">
[Code] ....
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:
1Â Â Â Â Â Â Â Â Very Poor
2Â Â Â Â Â Â Â Â Average
3Â Â Â Â Â Â Â Â Good
(.aspx.cs file)
protected void AddComment(object sender, EventArgs e)Â {Â Â Â Â Â Â Â Â Â Â Â
string constr = System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
string sqlStatment = "INSERT INTO FeedbackResponse(QUESTION_ID,RESPONSE) values(@QID,@RESP)";Â
using (SqlConnection con = new SqlConnection(constr))Â {Â
using (SqlCommand cmd = new SqlCommand(sqlStatment, con))Â {Â
con.Open();  cmd.Parameters.AddWithValue("@RESPONSE",this.rptComments.  Â
cmd.ExecuteNonQuery();Â con.Close();Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
} }
I am not sure what to do in the bold line.
