here's what I mean:
I have a few controls, for example,
<asp:DropDownList ID="ddlDate1" runat="server" />
<asp:DropDownList ID="ddlDate2" runat="server" />
<asp:DropDownList ID="ddlDate3" runat="server" />
in my javascript, I want to do something like this:
for (i = 1; i <= count; i++) {
something[i] = document.getElementById("<%= ddlDateRange" + i + ".ClientID %>");
}
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.
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.
My aspx has a placeholder I am dynamically loading a user control into the placeholder
like this:
Control dynamicControl = Placeholder1.Page.LoadControl("~/SiteUserControls/Message/MessageInbox.ascx");
I have a GridView:

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 created a web user control (MemberDetails.ascx) which is loaded dynamically on a page (Member.aspx) for my website. The control has some TextBoxes. I want to store the values inputted by a user in these TextBoxes to a database on the click event of a button that is on the Member.aspx page (i.e. not a part of user control).
I'll use a small code for example.

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 want to create custom control (let's name it DesignPanel) that will allow user to design his own webpage structure that would be stored in a sitemap file. This Design Panel will have child controls inside ( SiteElement). User will build page strcture by connect Site Elements, customize them ( like change name) and add new ones.
This last point is main issue for me. Should I add those Site Element controls dynamically like DesignPanel.Controls.Add(new SiteElement()) in UpdatePanel control or there is better approach ( adding them to DOM structure by javascript, something diffrent)?
I have a GridView with a column of checkboxes. I also have a panel pnlSubmitOffer which serves as a modal dialog with ajaxToolkit:ModalPopupExtender:
[Code]....
I need a set of controls (text boxes and datetimepickers) to appear on the modal dialog based on how many checkboxes in the GridView are checked, i.e. a set for each checked record. Thus the controls should be added to the panel dynamically. But I don't know how to do it, as btnSubmitOffer click is not handled, because the modal dialog appears first. I was told that the controls can be added dynamically using javascript, but my knowledge of it is not enough.
I'm creating an ASP.NET control dynamically based on a value selected in a dropdown; for instance the field can be a textbox or a checkbox (for now), and then it gets added to a placeholder control. However, I'm unsure how to retrieve the value - using the placeholder's FindControl method returns null although I'm specifying the ID when I create the control.
Here's my code:

I am writing a survey generating system in asp.net. i asked an ealier question about the best way to create controls that can be passed about as variables. This was problematic with user controls so i was advised to use custom controls and a quick way to do this was to inherit from the panel control and just add a bunch of standard controls the the controls collection by overriding the CreateChildControls method. This way i could create my "survey" controls,which are basically Questions in the survey. THe question controls are then dynamically added to the page. This all works well but know i have come to the point that i want to try and retrieve the values from these controls and i seem to be lost in a nether world of of viewstates and page lifecycles. I can ensure that the dynamically added text boxes have a known ID, however even if i add the parent control in the page init handler the CreateChildControls method does not run until after until after the viewstate is loaded. I cannot work out how to retreive the values from these text boxes.
View 2 RepliesI 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).
Is there a way to add asp.net server side control dynamically on the webpage without causing postback. Like can I add a calender control dynamically on a button click and handle calender events to do some other work....
View 1 RepliesI 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've tried creating checkboxes, literalcontrols and textboxes. I need to generate checkboxes dynamically, depending on how many types of <whatever> the user has put in. I know how to do this (I think), but the problem is the controls don't work as they should.
If I create server controls, then for some reason I can't change the value with javascript. If I create client controls, then something appears to happen with the id so the server can't fetch the value (it doesn't recognize the id, allthough it's there in the html)
I can't use a regular checkbox with autopostback because there is to much happening at page load. On other pages on the site, this works, but on those pages the controls are not created dynamically.
I have ArrayList in my Model and want to iterate through it in my javascript. I am using following code but its giving me error : CS0103: The name 'i' does not exist in the current context

{
alert('<%=Model.KeyList[i]%>');
}
How to get rid of this?

How to maintain view state for the dynamically added html controls to a table using javascript(Below is the javascript which I am using to add HTML Controls Dynamically"). Because during the postbacks if I found any error while validating the data present in the dynamically added html controls, the controls are loosing their state and again I need to start adding rows and add data.
[Code]....
I have a small form with some static elements that I am able to access with javascript the bring up a popup. 4 textboxes are generated and attached to a updatepanel. I've been trying various methods of validating the contols without generating postback.
I found anytime i registered a javascript to the scriptmanager the page must refresh.
Is there anyway it can be done?

I'm working on an ASP.NET app.I'm using a UserControl for a year calendar.This UserControl has 12 asp.net calendar controls (for the 12 months of a year)
I'm trying to build a jscript function that can access to one (or more) of the 12 month calendar, but I can't access them.
example:
"<asp:Calendar ID="CalendarJanuary" runat="server"></asp:Calendar>"
here's my function
function SetCalendar(controlId) {
document.getElementById(controlId+'_CalendarJanuary').VisibleDate = somedate
}
but this is allways throwing an error:'Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object'
it seems is not finding the calendar and I'm sure i'm passing the right controlID
