Get Value Of Dynamically Created Radiobuttonlist?
May 24, 2010
I'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.

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?

I am dynamically creating a table which places a dynamically created radiobuttonlist in each row.
I then want to display the results on the page when the submit button is clicked.
I am getting an error message stating that
'question1' is not declared
Why might this be happening?? I've included all my code below.
Code behind:
Sub Page_Load(ByVal Sender as Object, ByVal E as EventArgs)
For i As Integer = 1 To 3
Dim TableRow As New TableRow()
Dim TableRowCell_1 As New TableCell()
TableRowCell_1.Text = i
Dim TableRowCell_2 As New TableCell()
TableRow.Cells.Add(TableRowCell_1)
TableRow.Cells.Add(TableRowCell_2)
QuestionnaireTable.Rows.Add(TableRow)
Dim question As New RadioButtonList
question.ID = "question" & i
question.RepeatColumns = "2"
question.Items.Insert(0, new listitem("", "1"))
question.Items.Insert(1, new listitem("", "2"))
TableRowCell_3.Controls.Add(question)
Next
End Sub
Sub btnSendFeedback_Click(sender as Object, e as EventArgs)
Dim question1 As RadioButtonList = DirectCast(Page.FindControl("question1"), RadioButtonList)
Dim question2 As RadioButtonList = DirectCast(Page.FindControl("question2"), RadioButtonList)
Dim question3 As RadioButtonList = DirectCast(Page.FindControl("question3"), RadioButtonList)
Response.write(question1.SelectedValue & " - " & question2.SelectedValue & " - " & question3.SelectedValue)
End Sub
Body:
<asp:Table runat="server" ID="QuestionnaireTable" />
<asp:Button OnClick="btnSendFeedback_Click" runat="server" Text="Submit..." ID="submitbutton" />

I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.

I have a website that sales associates access to view account information with clients. S.A's can only view information for accounts that they are tied to. Some clients have more than one account, S.A's can be tied to more than one account, but not all accounts of one client need to be tied to one S.A.
On the account info pages, I have account numbers (dynamically displayed labels) displayed of other accounts that the account client is associated with, which the S.A's can see. I'm modding this so that if the S.A has viewing permissions of any of the other accounts on that list of accounts, that instead of a label being displayed, a button directing them to that account page will display instead. In order for this to work, I have to attach a security function to the button, otherwise the page will blow out on the S.A's.
So I'm running a piece that is displaying a button instead of a label, which is working fine. My problem is when I try to attach the security event to the dynamically displayed buttons. It seems that the page just posts back and doesn't execute my code at all.
On my Page_Load, I'm running this after the buttons and labels are displayed:
For x = 0 to tblAccountList.Rows.Count - 1
'use a try to target the button, use catch to handle if it's instead a label, only one cell per row.
Try
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try
Next
I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.

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.

Dynamically populated Radiobuttonlist?
View 1 Replies
Oct 12, 2010
I 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 ...

I have a grid and on each row of grid i generate a radiobuttonlist with 2 items dynamically in rowdatabound. 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. I tried to use hidden field so that whenever any radio button is selected in a row then in javascript i will update the hidden field but user can select multiple rows so this is not a good solution.
Here is my code of dynamic radio button list generation in rowdatabound event.

I'm creating 14 textboxes for every day in a month and user can select the month so i have o create them dynamically. But i can't reach the values in the textboxes.
When i don't create them dynamically like
<asp:TextBox ID= "TextBox1" name="TextBox1"> </asp:TextBox>
I can get the value from the C# side by using the
((TextBox)Page.Form.FindControl("TextBox1")).Text
However this moethod doesn't work for the textboxes that i created dynamically. I'm creating them in a loop it's something like;
[Code]....
Then i add the text box to the necessary places at my table.However i can't reach the textboxes when i use the same method
((TextBox)Page.Form.FindControl("!A uniqe ID!"));
It gave a null value...

In my code behind (c#) I dynamically created some RadioButtonLists with more RadioButtons in each of them. I put all controls to a specific Panel.What I need to know is how to access those controls later as they are not created in .aspx file (with drag and drop from toolbox)?
I tried this:
foreach (Control child in panel.Controls)
{
Response.Write("test1");
[code]....
"test1" and "test2" dont show up in my page. That means something is wrong with this logic.

I know this question has been asked thousands of times, and I've struggled with it before, but for some reason, I can't accomplish what I want to accomplish... I have a dynamically added LinkButton that when clicked will dynamically add a control (in this example, a textbox) to the same panel. The intent is to continuously add on as many controls as times the LinkButton was clicked (i.e. I click it once, one box, then another click will give me 2 boxes, another click adds a 3rd). In the code below, I use the current date and time serialized to create a unique ID for each textbox control.
When I execute the code, clicking "Add Filter" will generate a new textbox, but once clicked again will create a new one, and dispose of the one before it. Instead, I want to persist the previous textbox as well as any data submitted within it.In the aspx:
<asp:Panel ID="pnlFilter" runat="server">
</asp:Panel>
In the aspx.cs:
protected void Page_Init(object sender, EventArgs e)
{
LinkButton lb = new LinkButton(); [code]....

I'm creating textboxes in the Page_Load event and giving them values, however whenever I load the details I am getting the same output. I always seem to get the first output I got, even on subsequent searches.Here's what my code with the irrelevant information missing:
Textbox txtName = New Textbox();
protected void Page_Load(object sender, EventArgs e)

If DropDownList has two values (e.g. "Item 1" and "Item 2") and has autopostback enabled, first time it will generate and show "Item 1" in the textbox (the default value for the DropDownList), but if this is changed and the autopostback fires, the textbox does not change.I've tried getting around this by creating a new TextBox, overriding the "LoadPostData" function to prevent this from loading, which got around the issue there, but then I couldn't view the data afterwards.
Any idea how I could get around this? I may be approaching this in the wrong way.Edit: I've added another item to DropDownList that removes TextBox, so that it can be re-created again. It seems to show the correct data when it is re-created after being removed, but if I'm attempting to just edit it, this isn't updating correctly.Edit2: Here's the rest of the code for this page in case this helps at all. The objects which I'm having issues with are SBUName and SBUComments, which are both TextBoxes. The same issue is also happening for SBUClientDropdown but I believe the resolution will be similar:
DBHandler DBHandler = new DBHandler();
List<string> clients = new List<string>();
List<string> clientGroups = new List<string>();

I am trying to add a unique name to each textbox that I'm adding to a table.
I've tried:
TableRow someRow = new TableRow();
TableCell someCell = new TableCell();
TextBox someTextbox = new TextBox();
someTextbox.Attributes.Remove("name");
someTextbox.Attributes.Add("name",itsId);
someCell.Controls.Add(someTextBox);
someRow.Cells.Add(someCell);
theTable.Rows.Add(someRow);
The html generated includes both my name and the autogenerated name as attributes of the textbox.
Unfortunately, when I run a FindControl, by my name, I get a null reference, even though it still works to find it by the autogenerated name.
What do I need to do to find the control by my name? When / why is it autogenerating names for my controls?
Successful code:
TextBox tb = (TextBox)FindControl(autogeneratedID);
WriteToSomeOtherDiv(tb.Text);
Unsuccessful code:
TextBox tb = (TextBox)FindControl(myId);
WriteToSomeOtherDiv(tb.Text);
