I'm trying to use the following loop to loop through dynamically created controls on my web form:
for(x = 0; x <= count; x++) {
Stmt += $("#DDLColumns" + x).val();
switch($("#DDLConditional" + x).val()) {
[code]...
Say for example, I have script like below whereby everything is same except the table name and each table name will append an incremental number, is it possible for me to have a for loop to dynamically add the incremental number?
CREATE TABLE Persons1

P_Id int,

A short background about this project: I'm creating an image gallery where images are uploaded and sorted into a category and then a subcategory, eg. "Vehicles" and "Cars". Every subcategory has a variety of tags to further categorize the picture, eg. color and make in the cars subcategory.
These tags (named "Criterias") are listed as DropDownLists through the following piece of code:
[Code]....
My problem now is that I can't figure out how to loop through them to find what criteria values to tag the image with.
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 am creating Textboxes at Runtime with something like this
Code:
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
Code:
$(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) {
$('#count').html(count);
$('#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 ?
Code:
contentbox
this is the name of the Textbox in my example. how do we use a J Query in Dynamically created Textbox.
in an aspx pege, on Page PostBack we generally get thsoe control that were created either in aspx or code behind (dynamic controls ). But in jQuery its common practice to craete new set of controls on the fly. Supose i have created 10 spans with some id and text . So, can we get these spans on server side on Page PostBack ?
View 5 RepliesI am trying to validate dynamically created text inputs. I have been following tutorials about how to do jquery validation using the validation library, but I cannot seem to get this to work.
Heres the code where I generate the inputs.

I've a JavaScript function in my page through which i make some elements in the page as 'JQuery UI droppable'.
function setDroppableTargets()
{
$(.cssDockZone).droppable();
}
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.
$(.cssDockZone).length
I've created a bunch of asp:hiddenfields dynamically at runtime in an asp.net page.
My question is this:
How do I find those hidden fields?
I have an event attached to a control that fires a javascript function, and that's where I am attempting to use JQuery to find the hidden field associated with that control.

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 would like to find out if there is anyone who would know how to read from a database then returns the same number of records that a stored procedure returns and display those records on the webpage there after pass the ID of the record to a variable to another stored procedure that displays the data related to the record that was clicked, I tried doing this in a asp.net repeater but I can't seem to be able to reference the controls inside the repeater.

I have a tree view with checkboxes for leaf nodes. If i click on checkboxes, I am creating some html controls dynamically. And in other static button click event I need to get an ID's of those dynamically created controls.
My Code is:
.aspx
<asp:Panel ID="pnlOuter" runat="server" Visible="false" Width="650px">
<table>
<tr>
<td>
<asp:Label ID="lblQtnrName" runat="server" Text="Questionaire Name"></asp:Label>
<asp:TextBox ID="txtQtnrName" runat="server"></asp:TextBox>...
I will have to retrive data from database assume this is the data I got
|No | Name|
46 ANN
24 LISA
20 JOAN
41 JACK
and so on. I will have to create checkbox dynamical by these data like this
checkbox ANN checkbox LISA checkJOAN
checkbox JACK
I will create a container and then create checkbok , then add control to container.. my problem is how to give it a break each 3 controls? and how to format them like this
<TR>
<TD width =33%>
checkbox ANN
</TD>
<TD width =33%>
checkbox LISA
</TD>
<TD width =33%>
checkbox JOAN
</TD>
</TR>
<TR>
<TD width =33%>
checkbox JACK
</TD>
</TD>
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 want to preserve the dynamically created control when postback occurs .
protected void Page_Load(object sender, EventArgs e)
{
} It can be achieved by calling CreateTable() in Page_Load. Is there any alternative way to preserve the control

How I can determinate width of some asp.net control, that was created dynamically?
For example I have such code:
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
<encosia:HighslideManager ID="HighslideManager1" runat="server" FadeInOut="true"
OutlineType="RoundedWhite" ControlBar="false" />
<table style="width: 100%; padding-left: 15px; padding-right: 15px;">

I need to calculate width of imageTD. I've trying to calculate its width in pages events, but this property also like other styles property is empty.
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.
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 ).
I have a control declared with PartialCaching attribute, like this:
[PartialCaching(60 * 60 * 12)]
public class MyControl : Control {
// control contents ...
}
but I create it in code, using new keyword. The problem is that if the control is in cache I must not create the control again the next time, but I need to add the control to the page hierarchy, otherwise nothing is going to be rendered. What I need in pseudo-code is something like this:
if (myControlIsCached) {
var ctl = ???; // something that represents the cached control
// e.g. could be: new LiteralControl( myControlCachedData ) [code].....
i wrote a function to create dynamic table in code behind on selectedindexchanged of checkbox,that is when user will check 2 checkboxex 2 tables will be generated with textboxes,Then on button click i want insert values of these textboxes in database,for that i want to find textbox using findcontrol,but i could not find it,
So i called same function of table creation on page load,but then it shows error that textbox is having duplicate id
I have a set of dinamically created User Controls on the page. They are pretty small 170X120 px in size, but when the page is displayed, they are all one under the other. All styling is default, which means they should be positioned in normal flow. Is there any way to place them next to each other. This is not a problem when I dinamically create for standard controls, like a button or an image. Why the user control is different. This is the markup behind the control:
[Code]....
and this is how I create them:

I was looking through my transcender exam kit for 70-562 and they say load dynamically created controls in the loadviewstateEvent. This should be CreateChildControls() instead, no?
