Dynamically added partial view with DatePicker not working as expected

I have a Partial view (_SubView) which is having multiple controls
<script type="text/javascript">
$(document).ready(function () {
$(".datepicker").datepicker({
showOn: 'both',
dateFormat: 'dd-MM-yy',
buttonImage: "#Url.Content("~/Content/Images/Icons/Calendar.png")" , //"../../Content/Images/Icons/Calendar.png",
buttonImageOnly: true,
changeMonth: true,
changeYear: true,
//altFormat: 'yymm',
onClose: function (dateText, inst) {
$(this).datepicker();
$(this).change();
}
});
$(".datepicker").datepicker().keydown(function (e) {
e.preventDefault();
// TAB: 9
// LEFT: 37
// UP: 38
// RIGHT: 39
// DOWN: 40
// IE OTHER
var code = e.keyCode || e.which;
DatePickerKeyDownEvent($(this).val(), code);
if (currentDate != null) { $(this).datepicker("setDate", currentDate); }
});
});
</script>
#using(Html.BeginCollectionItem("form")
{
// A set of labels and dropdown controls
#Html.TextBoxFor(x => x.MaturityDate, new { #class = "datepicker", #title = "Enter Maturity Date",id="date-picker" })
}
In main view, I have a button "Add New Item". When ever user clicks on Add New Item, _SubView will be added to the main view dynamically.
Question:
When ever user dynamically add multiple partial views to the main view and try to change individual maturity date , date is changing only in the initially added partial view.
But when user tries to change the date using keydown event, respective date control is changing correctly without any issues.
Can anyone help me where exactly I am doing wrong?
Regards

I believe the problem is happening because you set the input id to "date-picker",
remove id="date-picker"

Link button will not work with JQuery modal form

I have a JQuery modal form with 4 image buttons. When the modal box opens and I click on those buttons then nothing happens. I know that when the box opens it moves outside of the form but I do not know how to get it back. I have tried several variations on the .parent().appendTo($("form")); and have changed that in many different ways with no success. Currently when I use that the box opens up but the entire screen is darkened and I cannot click on the buttons. Here is my JQuery function:
<script type="text/javascript">
$(function () {
$("#Change").dialog({
resizable: false,
draggable: false,
width: 800,
modal: true,
show: { effect: 'fadeIn', duration: 500 },
hide: { effect: 'fadeOut', duration: 300 },
autoOpen: false,
open: function (type, data) {
$(this).parent().appendTo($("form"));
}
});
$("#ui-dialog-title-dialog").hide();
$(".ui-dialog-titlebar").removeClass('ui-widget-header');
$("#openChange1").click(function () {
$("#<%=txtCardChange.ClientID %>").val("1");
$("#Change").dialog("open");
$('.ui-widget-overlay').live("click", function () {
$("#Change").dialog("close");
});
return false;
});
});
</script>
If needed here is my html to call the modal form:
<a id="openChange1" href="#" style="color: Red">Change Card</a>
The html for the modal form is just inside a simple div tag:
<div id="Change">
\\html here
</div>
So, any help would be greatly appreciated. If needed I am using Visual Studio 2012 with .NET 4.0. The code behind the buttons are in C#. Thank you for your time.

I had the same problem I solved as below:
<script type="text/javascript">
$(function () {
$("#Change").dialog({
resizable: false,
draggable: false,
width: 800,
modal: true,
show: { effect: 'fadeIn', duration: 500 },
hide: { effect: 'fadeOut', duration: 300 },
autoOpen: false,
appendTo: "form"
});
$("#ui-dialog-title-dialog").hide();
$(".ui-dialog-titlebar").removeClass('ui-widget-header');
$("#openChange1").click(function () {
$("#<%=txtCardChange.ClientID %>").val("1");
$("#Change").dialog("open");
$('.ui-widget-overlay').live("click", function () {
$("#Change").dialog("close");
});
return false;
});
});
</script>
In jQuery UI v1.10 they added an appendTo property, which seems to do the same thing as calling .parent().appendTo($("form")). The dialog appears on top of the grayed background. And Post back does work.

As you mentioned, JQuery moves the contents of the dialog to a direct child of the page body to solve several rendering issues: http://forum.jquery.com/topic/preventing-dialog-from-rearranging-dom-flow
The problem is that if you move the buttons immediately back, the 'overlay' div that is used to darken the rest of the screen and make the dialog modal (ie eat click events) prevents your button clicks from happening in the original location.
One solution is to use a clone of your Change div for the modal and bind click handlers that call click() on the original buttons.
Another option is to have the buttons call .NET's postback methods instead of letting the normal HTML form do the submit:
__doPostBack("ctl00$button_name_here");

<asp:LinkButton runat="server" id="openChange1" onclientclick="openChange1Click()" />
<script type="text/javascript">
function openChange1Click () {
$("#<%=txtCardChange.ClientID %>").val("1");
$("#Change").dialog("open");
$('.ui-widget-overlay').live("click", function () {
$("#Change").dialog("close");
});
return false;
}
</script>

Got it, thanks for the help, it steered me in the right direction.
$(function () {
$("#Change").dialog({
resizable: false,
draggable: false,
width: 400,
modal: true,
show: { effect: 'fadeIn', duration: 500 },
hide: { effect: 'fadeOut', duration: 500 },
autoOpen: false,
open: function (type, data) {
$(this).parent().appendTo("form:first");
}
}).parent().css('z-index', '1005');
$("#ui-dialog-title-dialog").hide();
$(".ui-dialog-titlebar").removeClass('ui-widget-header');
$("#Change").hide().show();
$("#openChange1").click(function () {
$("#<%=txtCardChange.ClientID %>").val("1");
$("#Change").dialog("open");
$('.ui-widget-overlay').live("click", function () {
$("#Change").dialog("close");
});
return false;
});
});

Display panel over another panel for web app

I was looking for an answer, but could not find anything helpfull yet.
I have a gridview with some data (from SQL database) and an option to delete a row. Before deleting the row I want the user to confirm the delete (pupup window). I know how to create a popup with javascript, but I don't like the apperance of that popup. I would like to make ky own "popup".
I was thinking of overlaying one panel (where I put text (Label) and some buttons (OK, Cancel)) over the panel where I have the gridview. Something like in the picture. How would I accomplish something like that?

How about using the Ajax control toolkit popup?

This seems to do exactly what you are looking for for you.

What about JQueryUI dialog with custom styling?

Use the jQuery UI dialog
Example:
<script type="text/javascript">
$(function () {
var $dialog = $("#dialog");
var $foo = $("input:submit[id$=foo]");
var confirmed = false;
$dialog.hide();
$dialog.dialog({
width: "300px",
modal: true,
autoOpen: false,
buttons: {
OK: function (e) {
$dialog.dialog("close");
confirmed = true;
$foo.click();
},
Cancel: function (e) {
$dialog.dialog("close");
confirmed = false;
}
}
});
$foo.click(function (e) {
if (!confirmed) {
$dialog.dialog("open");
}
return confirmed;
});
});
</script>

Using Asp button in jquery dialog

I have a problem in my code when I'm using an Asp button in a jquery dialog where modal is set to "true".
Here is my code :
Js
$(document).ready(function () {
var dlg = $("#mws-jui-dialog").dialog({
autoOpen: false,
title: "Delete",
modal: true,
width: "640",
minHeight : 160,
minWidth : 170
});
dlg.parent().appendTo(jQuery("form"));
$("#btnDelete").bind("click", function (event) {
$("#mws-jui-dialog").dialog("option", { modal: true}).dialog("open");
event.preventDefault();
});
$("#btnClose").bind("click", function (event) {
$("#mws-jui-dialog").dialog("close");
event.preventDefault();
});
});
On my aspx page :
asp:Button runat="server" ID="bidon" CssClass="mws-button green" OnClick="DeleteButton_Click" Text="Yes"
And on my cs :
protected void DeleteButton_Click(object sender, EventArgs e)
{
Response.Redirect("mypage.aspx");
}
When i set modal to false it's working fine but as i've understood that modal disable items on my page, i'm looking for a way to use my asp button when modal is at true (or just a another way to fix it).

I know your question is a few months old but if I understand it correctly... In your mws-button green CSS class. Include the z-index: property and set it too 1000. This will ensure that your button sits on top of the modal bkgd.
.mws-button green
{
z-index: 1000;
}
Let me know if this helps.

How to call a javascript function from a control within a masterpage?

I have a masterpage with a Login Control in it. When the Login button is clicked, I would like for a JQuery Dialog to popup if the user's membership is about to expire within 30 days, else it will just log them in as normal. I can't figure out how to do it. I wll post parts of code:
Here is the javascript:
<script type="text/javascript">
function showjQueryDialog() {
$("#dialog").dialog("open");
}
$(document).ready(function() {
$("#dialog").dialog({
autoOpen: false,
modal: true,
buttons: { "Renew Membership": function()
{ $(this).dialog("close"); } }
});
});
</script>
The login button is called ibtnLoginButton and here is part of the code:
//Grab the user profile.
UserProfiles userProfile =
UserProfiles.GetUserProfiles(txtUserName1.Text);
//Calculate the Time Span
TimeSpan timeSpan = userProfile.Expiration.Subtract(DateTime.Now);
if (timeSpan.Days < 30)
{
//Show JQuery Dialog Here
}
else
{
//Continue with Login Process.
}

how about this?
if (timeSpan.Days < 30)
{
//Show JQuery Dialog Here
ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "showExpiration", "showjQueryDialog()", true);
}

If, as you've said you've got this jQuery dialog to appear when clicking an asp:Button, why not just hide the button and change your javascript to just press the button once the page has loaded?

Why not always call the jquery method when the button is clicked, and then determine within the javascript method whether or not you want to show the dialogue? If not, just don't do anything. Since you're just checking whether ExpirationDate is smaller than now + 30 days, you can do that calculation just fine in javascript.
Edit:
I can't provide you with the exact solution, but here is some pseudocode to get you on your way.
First make the user profile's expiration date need available in javascript:
<script>
var userProfileExpiresOn = "<asp:Literal ID="userProfileExpiresOn" />";
</script>
Then edit your method so that it does the logic you're currently doing server-side for you:
<script>
function showjQueryDialog() {
if (userProfileExpiresOn < (now + 30 days))
$("#dialog").dialog("open");
}
</script>
You can find some documentation on how to work with dates in Javascript at W3schools.
