Accessing Controls Created Dynamically (c#)

Jun 5, 2010

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)

"test1" and "test2" dont show up in my page. That means something is wrong with this logic.

VS 2010 - Accessing Dynamically Created Server Controls

Jun 8, 2012

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?

VS 2010 - Accessing Data From Dynamically Created DropdownLists

Dec 20, 2012

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).

How To Use JQuery On Dynamically Created Textbox

Sep 27, 2011

i am creating Textboxes at Runtime with something like this

Dim cnt As New TextBox
cnt.ID = "cont_" & x
If multiline Then
cnt.TextMode = TextBoxMode.MultiLine
End If

These are dynamically created fields. so what i want to do is to use this following JQuery on this textbox

$(document).ready(function() {
$("#contentbox").keyup(function() {
var box=$(this).val();
var main = box.length *100;
var value= (main / 145);
var count= 145 - box.length;
if(box.length <= 145) {
$('#bar').animate({"width": value+'%',}, 1);
return false;

and what this function does it count the number of Characters that have been typed in a Textbox. so i am displaying the remaining characters. So that is working fine on my example because the Element is known at Early Binding. Now my question is what if the textbox is created dynamically ?



this is the name of the Textbox in my example. how do we use a J Query in Dynamically created Textbox.

Jquery - Access A Dynamically Created Control Through Javascript?

Sep 25, 2010

I've a JavaScript function in my page through which i make some elements in the page as 'JQuery UI droppable'.

function setDroppableTargets()

But the elements with the class cssDockZone is created dynamically upon user interaction. So in the code behind i create the control first and finally at the end i register a scriptblock which calls setDroppableTargets().

//set droppable targets ClientScript.RegisterClientScriptBlock(this.GetType(), "setDroppableTargets", "setDroppableTargets()", true);

But the javascript function is invoked before the controls are created eventhough i register the script at the end (after creating the controls) and i cross checked it by getting the elements with class name '.cssDockZone' and i getting it as 0.

Web Forms :: Use Dynamically Created Controls Such As A Checkbox List And Fill The Values Dynamically?

Sep 28, 2010

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.

Dynamically Created Controls And Postback

Nov 18, 2010

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">


In the aspx.cs:

protected void Page_Init(object sender, EventArgs e)
LinkButton lb = new LinkButton(); [code]....

Web Forms :: How To Use AddHandler To Dynamically Assign Events To Dynamically Created Buttons

Feb 14, 2011

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.
Dim accountLink as Button = tblAccountList.Rows(x).Controls(0)
Addhandler accountLink.Click, AddressOf Me.PermissionViewCheck
Catch ex as InvalidCastException
Continue For
End Try

I don't have any code checking for postbacks or anything like that, but the "PermissionViewCheck" event never fires and just reposts the page.

Web Forms :: Want To Put Code In Dynamically Created Controls?

May 28, 2010

I need to create web controls (e.g. label etc) dynamically.The problem is that for example,

on my onload event, I create a label. The text of the label is read from one line of a xml file.

But sometimes the text should be like " Messages (4)", in which the message count is something not generic and need some logic to calculate. I tried to put things like "Message (<#% MessageCount %>) " in my xml file, but the displayed text label is:

Message (<#% MessageCount %>) instead of Message (4 ).
