How to Send Data to KendoWindow Close Event

I'm trying to open a Kendo UI kendoWindow from within an MVC View. I also use a Partial View as the content of the kendoWindow. Moreover, I use the Kendo UI MVVM pattern to bind my elements.
First let me to show you my main View and my pop-up Partial View (kendoWindow).
The important part of my main View (Parent) is as follows:
#{
ViewBag.Title = "My Main View";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<script src="~/Scripts/ViewModel/main.js"></script>
<script src="~/Scripts/InitView/main.js"></script>
<script type="text/javascript">
var viewModel;
$(function () {
viewModel = initVm({
GetPartialContent_Url: '#Url.Action("GetPartialContent")'
});
initView(viewModel);
kendo.bind($("#container"), viewModel);
viewModel.Onread();
});
</script>
<div id="container">
<div id="Window-box"></div>
// Some other elements like the button which opens the kendoWindow are defined here.
</div>
My initVm is as follows:
function initVm(arg) {
var vm = kendo.observable({
onOpenKendoWindow: function () {
$("#Window-box").kendoWindow({
iframe: true,
content: arg.GetPartialContent_Url,
title: 'Some Title',
width: 500,
height: 'auto',
close: function (e) {
//Is it possible to get some data from kendoWindow (Partial View) here?
}
});
var dialog = $("#Window-box").data("kendoWindow");
dialog.maximize();
}
});
return vm;
}
Until now, I showed you the important parts of my main View. Now I want to show you the important parts of my kendoWindow (Partial View).
My Partial View which is used as the content of the kendoWindow is as follows:
#{
Layout = "~/Views/Shared/_PartialLayout.cshtml";
}
<script src="~/Scripts/ViewModel/partial.js"></script>
<script src="~/Scripts/InitView/partial.js"></script>
<script type="text/javascript">
var partialVM;
$(function () {
partialVM = initPartialVm({
GetTransactions_Url: '#Url.Action("GetTransactions", "Account")'
});
initPartialView(partialVM);
kendo.bind($("#container"), partialVM);
});
</script>
<div id="container">
<div id="gridTransactions"></div>
</div>
And my initPartialVm is as follows:
function initPartialVm(arg) {
var vm = kendo.observable({
onSelectTransaction: function () {
// KendoWindow should be closed here and passing some data from here to main View (close event of kendowWindow);
}
});
return vm;
}
Note: The 'gridTransactions' is a Kendo UI GridView (inside of kendoWindow - Partial View). Each rows of this grid has a select button and the 'onSelectTransaction' function is fired when each of these select buttons is clicked.
And finally, the main question is that, how can I close the kendowWindow by clicking each select button of the GridView and pass some data to the close event of the kendowWindow?

Yes it is possible. I found it much easier and a bit cleaner to wrap all the dialog functionality up into a dialog controller and extend it a bit in javascript.
Once the .js part is done it makes for a cleaner use. If you don't prefer to do this then look for the findDialog function below (it shows how get a handle to a dialog and call the close method on it).
As far as sending data on close, It would be easy to add a callback in the dialog to be called when the dialog is closed, supplied on invocation, then add a property in the widget to set the custom data to pass through in the dialogs close() back to the consumers event handler.
Also, please note I am no javascript expert, it took me longer than I would like to admit to work the bugs out of this but it has held up solidly for about 6 years. Feel free to offer suggestions.
In Bundle Config:
bundles.Add(new ScriptBundle("~/bundles/myCustom").Include(
...
"~/Scripts/MyCustom/MyCustomDialogs.js",
...
));
Where you register scripts:
#Scripts.Render("~/bundles/MyCustom")
In your index view or parent view :
<div id="_applicationDialogs"></div>
<div id="_mainAppContentLoadsHere"></div>
var _mainDialogController;
$(document).ready(function () {
...
_mainDialogController = $("#_applicationDialogs").kendoMyCustomDialogController().data("kendoMyCustomDialogController");
...
}
Where you want to invoke the dialog: SomePartial
function lnkDetailsOnClick(someID) {
_mainDialogController.createDialog({
dialogId: "frmUserDetail_" + someID,
modal: false,
title:"Daily Details",
pin: true,
height: 575,
width: 1025,
actions: ["Refresh", "Maximize", "Minimize", "Pin", "Close"],
url: '#Url.Action("SomePartialView", "SomeController")',
data:{
someID: someID,
dialogName:'frmUserDetail_'+ someID //NOTE : This will come back in the invoked partial as Model.DialogName so it can be dismissed with ease.
}
});
}
Dismissing the Dialog Inside of SomePartial :
#model MyModelThatHasTheDialogHandle
function btnClose_Click() {
var dialog = _mainDialogController.findDialog('#Model.DialogName');
dialog.close();
}
Now for the long .js file :

jquery fire event in dialog

How can I keep event of change of select into dialog that don't fire?
my HTML:
<body>
<div id="dialog_message"></div>
</body>
my JAVASCRIPT:
var titolo = 'my dialog';
var s="<select id=\"MYSEL1\" name=\"MYSEL1\"><option value=\"A\">opt A</option><option value=\"B\">opt B</option></select><br><select id=\"MYSEL2\" name=\"MYSEL2\"></select>";
$( "#dialog_message" ).dialog({
resize: 'auto',
draggable: true,
resizable: false,
closeOnEscape: false,
open: function() { // open event handler
$(this).parent().find(".ui-dialog-titlebar-close").hide();
$(this).html(s);
},
buttons: {
Annulla: function() {
$( this ).dialog( "close" );
}
},
title: titolo
});
$("select").selectmenu();
$("#MYSEL1").on("change", function() {
var n=$(this).attr("id");
var dd = $("option:selected", this);
var d = $(this).val();
alert (d);
$("#MYSEL2").empty(); // remove old options
if (d=='A') {
$("#MYSEL2").append('<option value=\"AA\">opt AA</option><option value=\"AAA\">opt AAA</option>');
} else {
$("#MYSEL2").append('<option value=\"BB\">opt BB</option><option value=\"BBB\">opt BBB</option>');
};
});
You can find in jsfiddle at: https://jsfiddle.net/t0L915po/5/

You will need to add the event to select element after the dialog box opens. Use the below code:
var titolo = 'my dialog';
var s="<select id=\"MYSEL1\" name=\"MYSEL1\"><option value=\"A\">opt A</option><option value=\"B\">opt B</option></select><br><select id=\"MYSEL2\" name=\"MYSEL2\"></select>";
$( "#dialog_message" ).dialog({
resize: 'auto',
draggable: true,
resizable: false,
closeOnEscape: false,
open: function() { // open event handler
$(this).parent().find(".ui-dialog-titlebar-close").hide();
$(this).html(s);
$("#MYSEL1").on("change", function() {
var n=$(this).attr("id");
var dd = $("option:selected", this);
var d = $(this).val();
alert (d);
$("#MYSEL2").empty(); // remove old options
if (d=='A') {
$("#MYSEL2").append('<option value=\"AA\">opt AA</option><option value=\"AAA\">opt AAA</option>');
} else {
$("#MYSEL2").append('<option value=\"BB\">opt BB</option><option value=\"BBB\">opt BBB</option>');
};
});
},
buttons: {
Annulla: function() {
$( this ).dialog( "close" );
}
},
title: titolo
});
$("select").selectmenu();

Cannot display data in a jQuery UI dialog via AJAX on opening

I just want to display following reviews which I got from my database on the Jquery UI dialog box on loading but it displays nothing:
{"results":[{"review_text":"good"},{"review_text":"not bad"},{"review_text":"great"}]}
Could you please check my code below and help me to find my mistake.
Here is my view:
<?php
$data = array(
'name' => $item_id,
'class' => 'all_reviews',
'content' => 'Reviews'
);
echo form_button($data);
?>
<div id="see_all_reviews">
<div id="load_reviews"></div>
</div>
Here is my JS file:
$(".all_reviews").click(function() {
var self = this;
var id = $(self).attr("name");
$.post('filter/get_reviews', { id: id }, function (data) {
var my_obj_review = data;
$.each(my_obj_review, function (i) {
var reviews_text = my_obj_review[i].review_text;
$("#load_reviews").text(reviews_text);
});
}, "json").error(function() { $( "#load_reviews" ).text(data.message);
});
$( "#see_all_reviews" ).dialog({
autoOpen: false,
title: "Reviews",
modal:true,
draggable:false,
width: 600,
height: 600,
close:function(){ $(this).dialog('destroy'); }
});
});

You primary issue is that your AJAX call is returning a data object not a data list. Replace:
var my_obj_review = data;
with:
var my_obj_review = data.results;
Additionally, this:
$(self).parent().find("#see_all_reviews").text(review_text);
can be replaced with this:
$("#see_all_reviews").text(review_text);
In either case, your each loop is going to replace that element with the last item in the list. Are you trying to append reviews to that div?
Finally, you may need to initialize your dialogue:
$("#see_all_reviews").dialog({
autoOpen: false,
show: "blind",
hide: "blind"
});
Here's your code refactored slightly:
$(document).ready(function() {
$(".all_reviews").click(function() {
var item_id = $(this).attr("name");
$.post('contr/get_reviews', { item_id: item_id }, function (data) {
$.each(data.results, function (n, result) {
$("#see_all_reviews").text(result.review_text);
});
// Above loop equivalent to:
$("#see_all_reviews").text(data.results[data.length-1].review_text);
}, "json")
.error(function(data) {
$("#see_all_reviews").text(data.message);
});
$("#see_all_reviews").dialog();
});
});

wait till jquery dialog box returns

I need to open a popup window on clicking a button and used jquery dialog for this.
$(document).ready(function(){
$("#dialog-form").dialog({
autoOpen : false,
height : 300,
width : 350,
modal : true,
buttons : {
"Add" : function() {
$("#tag1").text($("#textArea").val());
$(this).dialog("close");
},
Cancel : function() {
$(this).dialog("close");
}
},
close : function() {
$("#textArea").val("");
}
});
});
function openWindow(){
$("#dialog-form").dialog("open");
statement1;
statement2;
}
<button id="add" onclick="openWindow()">Add</button>
problem over here is when i click the button dialog box is opened, but before even i enter some text in the dialog box statement1 and statement2 are getting executed and then focus is coming to the dialog box.
How can i make the statement1 and statement2 to execute only after dialog box returns?
I don't want to add the statement1 and statement2 to the "Add" function. The reason for not adding the statements in the "Add" function is because i have multiple buttons and each of these should first open the dialog box and then will execute different set of statements.

Easy fix would be to use the close callback:
$(document).ready(function () {
$("#dialog-form").dialog({
autoOpen: false,
height: 300,
width: 350,
modal: true,
buttons: {
"Add": function () {
$("#tag1").text($("#textArea").val());
$(this).dialog("close");
},
Cancel: function () {
$(this).dialog("close");
}
},
close: function () {
$("#textArea").val("");
//statement1 -- won't fire until dialog is closed
//statement2 -- won't fire until dialog is closed
}
});
});
function openWindow() {
$("#dialog-form").dialog("open");
}
Another thing to consider would be $.Deferred

I have an example for you:
$(".selector").click(function () {
var dialog = $('<div title="Title"></div>').dialog({
open: function (event, ui) {
$.ajax({
url: 'www.google.com.br',
cache: false,
success: function (html) {
$(dialog).html(html);
},
error: function () {
$(dialog).remove();
alert("Some Error MSG");
}
});
},
close: function () {
$(dialog).remove();
},
resizable: false,
width: 500,
modal: true
});
});
In this case, the dialog is receiving the HTML result, only after it opens.

This can be achieved by the following way:-
$('#mydialog').dialog("open");
$('#mydialog').load('serverURL',server_data_variable, function() {
myfunction();
});
This will execute the function once the dialog loading is done.It will register the callback to be executed post dialog done.The variable server_data_variable is optional and is supposed to be used only if user wants to send some data otherwise it can be skipped as.well.

Solution 1: (same as solution from Aaron Blenkush)
$("#dialog-form").dialog({
autoOpen: false,
height: 300,
width: 350,
modal: true,
buttons: {
"Add": function () {
$("#tag1").text($("#textArea").val());
$(this).dialog("close");
//statement1 -- will fire only if "add" button is clicked
},
Cancel: function () {
$(this).dialog("close");
}
},
close: function () {
$("#textArea").val("");
//statement1 -- will fire after dialog is closed
}
});
Solution 2 is to make a promise:
const dialogPromise = new Promise(function (resolve, reject) {
$("#dialog-form").dialog({
autoOpen: false,
height: 300,
width: 350,
modal: true,
buttons: {
"Add": function () {
$("#tag1").text($("#textArea").val());
$(this).dialog("close");
resolve(true);
},
Cancel: function () {
$(this).dialog("close");
resolve(false);
}
},
close: function () {
$("#textArea").val("");
}
});
});
const addClicked = await dialogPromise;

Call callback function after "open" clause in the dialog setup.
modal: true,
resizable: false,
resize: 'auto',
close: dialogCloseFunction,
**open: function(){if(itemid) {showDailogSides(itemid);}** if(!siteParams[3]) {$(".detailSideClass").hide(); $(".addToChartinDialog").hide();}},
//hide: {effect: "fadeOut", duration: 5000}
show: { effect: "fade", duration: 1000 } //drop blind fade fold slide clip

jQueryUI Dialog with Ajax Form Won't Close with $(this).dialog("close");

I have a jQueryUI Dialog loading up a form from an external url, the form renders fine and posts ok but neither the save or cancel buttons seem to close the form yet the dialog close icon does it's job just fine.
Here is my script that spawns the dialog and should handle the buttons:
$(function () {
$('a.modal').on('click', function() {
var href = $(this).attr('href');
$("#modalAdd").html("")
.dialog({
title: $(this).attr("title"),
width: 400,
height: 300,
buttons: {
"Save": function() {
$.post(href,
$("form").serialize(),
function() {
$(this).dialog("close");
});
},
Cancel: function() {
$(this).dialog("close");
}
}
})
.load(href, function() {
$(this).dialog("open");
});
return false;
});
});
The final solution was to declare the variable outside of the scope of the dialog declaration as follows:
$(function () {
$('a.modal').on('click', function() {
var href = $(this).attr('href');
var modal = $("#modalAdd");
modal.html("")
.dialog({
title: $(this).attr("title"),
width: 400,
height: 300,
buttons: {
"Save": function() {
$.post(href,
$("form").serialize(),
function() {
modal.dialog("close");
});
},
Cancel: function() {
modal.dialog("close");
}
}
})
.load(href, function() {
**modal**.dialog("open");
});
return false;
});
});

It's because of variable scope, as soon as you start the call back function for the $.post call, this is no longer the dialog box. Try calling $("#modalAdd").dialog('close'); instead.
If you don't mind expanding your $.post() and $.load() calls, you can set the context of this to a certain element using the full $.ajax() method. See the "context" option in the docs.

this is changed in the ajax callback function, you need to cache to a local variable.
"Save": function () {
var $this = $(this);
$.post(href, $("form").serialize(), function () {
$this.dialog("close");
});
},
