On my server side code I create a list of radio buttons with a loop:
[Code]....
The buttons are set to auto post back.On page_load I can get the ID of the radio button that was clicked with:
[Code]....
Now I would like to reference which list item was selected?
is 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 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.
I have a writing a web page that will use several different types of control. The control types will depend on the data being read from a SQL database. The following is my code that decides what control to add to the page:
Select myReader.GetString(1)
Case "DatePicker"
Dim bdpAnswer As BasicFrame.WebControls.BasicDatePicker = New BasicFrame.WebControls.BasicDatePicker()
bdpAnswer.DateFormat = "dd/MM/yyyy"
divAnswerContainer.Controls.Add(bdpAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "DropDownList"
Dim ddlAnswer As DropDownList = New DropDownList()
divAnswerContainer.Controls.Add(ddlAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "RadioButton"
Dim rbAnswer As RadioButton = New RadioButton()
divAnswerContainer.Controls.Add(rbAnswer)
Answers.Controls.Add(divAnswerContainer)
Case "TextBox"
Dim tbAnswer As TextBox = New TextBox()
divAnswerContainer.Controls.Add(tbAnswer)
Answers.Controls.Add(divAnswerContainer)
End Select
I made a web form in asp.net and I am using loop to add button on the page. But problem is this, I'm not able to handle event of it.
View 1 Repliesm new to .NET. I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button,
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>

I've created an array of buttons like static Button[] myButtons = new Button[3];
and then creating and adding buttons to my panel like myButtons[i] = new Button();
myPanel.Controls.Add(myButtons[i]);
in my code behind.
How can I handle the events that occurs when a user clicks these buttons, like using OnClick="myMethod" with regular buttons?
I created a web site with admin control with C# ASP.Net. Admin can create a new button1 with button2.I did this. but when admin login again the created button is not seen.I guess I should save this created button at SQL Server but how should I do.

Button btn2 = new Button(); btn2.ID = "btnEdit"; btn2.Text = txtKategoriEkle.Text; btn2.Attributes.Add("OnClick", "btnEdit_Click"); btn2.Attributes.Add("onclick", "my_javascript_function"); form1.Controls.Add(btn2);

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 have a link button which i have created dynamically and added it to a div i want to access this link button in some other function in code behind how to do this

I have this LinkButton in the ItemTemplate section... I want to add a jQuery Popup when the user will click on it. The message that will be displayed depends of the value in the label. Is there a way I can do that?
I have it setup so that when a user selects an item from a DropdownList, that some DropdownLists are dynamically created, based on the results from the Database that are returned after selecting the item in the first DropDownList.
Then, I have a button that takes the data and saves it to an object I've created for this, and I try to iterate through the Controls of the Placeholder that I added the DropdownList controls to.
However, the Placeholder says there are no controls in it, when I press the button, but I can obviously see them there.
Here is some code:
When a "Pilot" is selected, I get all of the Upgrade Types that that "Pilot" has access to, then I create a DropdownList for each type of Upgrade with all the actual Upgrades of that Type:
VB Code:
For Each u As UpgradeTypeList In upgrades
Dim lbl As New Label
Dim ddl As New DropDownList
ddl.AutoPostBack = False
[Code] ....
Then, when the "Add Squad Member" button is pressed, I am trying to iterate through the controls, pick out any DropdownLists and get the values from them and add them to a List Of in an object for the Pilot info:
VB Code:
Protected Sub btnAddSquadMember_Click(sender As Object, e As EventArgs) Handles btnAddSquadMember.Click
For Each c As Control In rowUpgrades.Controls
If TypeOf c Is DropDownList Then
Dim DoesExist As Boolean = False
[Code] ....
But, the controls supposedly don't exist and no values get added to the List(Of).
I am dynamically creating controls from javascript. Now i want to access this is server side.
I assigned all the control values from dynamically created controls to hidden field and accessed that in server side. For this i need to create many hidden fields as much as dynamically added controls.
Ok, so I'm dynamically adding <input type="File" />'s to the page via button click, client-side via Javascript.
Now when I click the upload button I can access the PostedFiles server side, but I also have radio button lists that I've created dynamically as well with no runat="server".
If I were to .setAttribute("runat","server") for the radio lists I create, is there a way to access that client-side created server control, from the server side?
I have a page where i am creating a number of <span> elements using clientside code.
I am creating the elements using jquery like this
[Code]....
But this returns a null object everytime. I have tried this code on a span that is on the page at the beginning and it works so i guess its something to do with how im creating the control dynamically.
i have a table which looks something like the following
<table id="Table1" border="0">

<asp:Table ID="Table1" runat="server">

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.

View 8 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.
