I 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.

validate the text boxes which are created dynamically?
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 am trying to figure out how to get the text value from each textbox on a page that has a dynamically created number of text boxes. I need to store that value in a database row. I guess what i need is to be able to store the text box values in a collection or arrary of some sort and then be able to use textbox(i).value or something of that nature. Not really sure where to begin.
View 5 RepliesI am validator controls to validate all of the my inout controls.
My requirement is i need to validate all of the inputs before saving and updating. I have no problem in that because by default all of the input conrols are validating based on the validation rule.
I have the Copu flag option in dropdown, when i am in the the Copy option i dont need to validate some of the input controls or dont need to validate all of the input controls when i clicked Save or Update button.
How can I add the dynamically added control to validation?

the client-side validations kicks-in. Is there a way to explicitly include the deferredly-created inputs to validations?
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 ?

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'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.

how to set text property assigned to the control created dynamically usiong reflection?
Type type = Type.GetType(strFullName);
object instance = Activator.CreateInstance(type);
ctrlTemp = (Control)instance;

i can add the dynamic textbox in dynamically created html but can not get the value of dynamically added textbox.
there is code what i do
protected void txtNoOfTypes_TextChanged(object sender, EventArgs e)
{
int n = Convert.ToInt32(txtNoOfTypes.Text)+1;
for (int i = 0; i < n; i++)
{
Label MyLabel = new Label();
MyLabel.Text = "Type" + " " + ViewState["num"] + i + " " + ":" + " ";

Let's say I have some HTML and Javascript which adds text fields dynamically to a form:

What might the ASP.NET code for capturing the data from these dynamically created text boxes look like?
I would like to know how to use jQuery's Validate plugin to add rules to validate controls in ASCX custom user control?
View 4 Repliesdo have a very particular question and if you want to answer it go straight to the end. But I do welcome comments and advices hence the lengthy post. we deal with a lot of forms and some of these forms are quite lengthy and have many fields. We also have a requirement - in addition to top level fields - to be able to have variable number of repating rows - as we call them. For example, let's think of a customer which has name, surname and age while it can have zero or many addresses (say 0 to 10) so the user must be able to add or remove contacts from the form while filling it in.
View 4 RepliesI am trying to send data from text fields created on the client side (via jquery). The problem is the data from those text boxes is not being post back ( I'm using asp.net webforms)
I have used fiddler to view the post back data and it isn't there for those generated text fields.
I'm surprised no one figured it out. I was switching from server to non server controls I forgot to give the non ones a name field..........
// Add answer field
$('#addAnswer').click(function ()
{
count++;
var html = '<p>' +
'<input id="answer' + count + '" type="text" maxlength="255" runat="server" />' +
'<a id="removeAnswer" class="removeIcon" href="#"><img class="removeIcon" src="/Content/images/minus.gif" /></a>' +
'</p>'
$(html).appendTo('#answers');
return false;
});
I need to save all the inputs to my MS SQL DB from the ASP.Net page inputs...
When i save this information, It has to check whether exists or not...
If its exists then it shows The Customer already exists..
If it does not exists it needs to show like , Thank You for register with us.. , and after 5 secs it automatically redirect to some other pages...
This all can be done under update panel...
Here i am using,
tr_exists.InnerHtml = "Thank you for register with us..";
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.
My web page has two ways of displaying a particular content. 1. When the page is loaded, the items ( images with anchor tag) are generated using ASP Repeater. 2. When user perform some Ajax action, the images are returned as JSON and I use jQuery for creating the a & img tags.In both these methods, the anchor tags with images are displayed with width 60px. There is no CSS class applied. But strangely the display is not consistent. Here is the both displays:I wonder why this difference occur. I check this with all browsers ( IE,FF& chrome) and all behave the same. Here is my jQuery code:
$('<a>').attr({ href: '/Detail.aspx?id=' + result.it[i].pid, title: result.it[i].nam }) .html("<img src='" + result.it[i].url + "' title='" + result.it[i].nam + "' alt='" + result.it[i].nam + "' width='60px' />").appendTo("#SummaryDiv");
Any idea why this behaviour occurs? I also checked the css applied to these elements in chrome and FF.. they seems to have all the same CSS attributes.
To prevent my application from crashing with the error "A potentially dangerous Request.Form value was detected...", I just turned page validation off. I want to revisit this and solve it correctly. Is there a good strategy for this? If people are entering '<' and '>', I think the only way to save their data is to encode it via Javacript. I have tried catching it in the code-behind, but it becomes too late. I am thinking of inheriting the textbox and auto encode/decode the input with client scripts. I also have to think of all the angle brackets that are already saved in my database.
