Error when using logic in ClientRowTemplate

I meant ClientTemplate. It won't let me edit the title of this post.

columns.Bound(t => t.IsOpen)
.Title("Status")
.ClientTemplate(
"# if (#=IsOpen# == 'True') { #" +
"something" +
"# } else { #" +
"something else" +
"# } #"
);

Uncaught Error: Invalid template:'<tr data-uid="#=uid#"><td ># if (#=IsOpen# == 'True') { #something# } else { #something else# } #</td></tr>' Generated code:'var o,e=kendo.htmlEncode;with(data){o='<tr data-uid="'+(uid)+'"><td >'; if (;o+='=IsOpen'; == 'True') { ;o+='something'; } else { ;o+='something else'; } ;o+='</td></tr>';}return o;'

Problem when closing modal window

I need to create a scheme where my pages open windows within the iframe contained in KendoWindow.
To establish a modal window I need to create it from within my home, because if you create it within a modal child page to only cover the child page.
I'm having to develop a scheme for windows like a desktop application.
Below is the JavaScript library I wrote to do this for me:

var kendoWindowFactory = new function () {

var __modalKendoWindow;

var __functionCallback;

this.createKendoWindow = createKendoWindow;

this.createModalKendoWindow = createModalKendoWindow;

this.modalReturn = modalReturn;

function createKendoWindow(element) {

var frameId = "___kendoWindow_" + element.id;

var LINK = element.href;

var TITLE = $(element).attr("data-title");

var WIDTH = $(element).attr("data-width");

var HEIGHT = $(element).attr("data-height");

if (!(parseFloat(WIDTH) > 0)) {

WIDTH = "50%";

}

if (!(parseFloat(HEIGHT) > 0)) {

HEIGHT = "50%";

}

var kendoWindow = document.getElementById(frameId);

if (kendoWindow) {

$(kendoWindow).data("kendoWindow").toFront();

}

else {

kendoWindow = $("<div />")

.attr({ id: frameId })

.appendTo("body");

$(kendoWindow).kendoWindow({

title: TITLE,

modal: false,

width: WIDTH,

height: HEIGHT,

content: LINK,

visible: false,

deactivate: function () {

this.destroy();

},

}).data("kendoWindow").center().open();

$(kendoWindow).css({ overflow: "none" });

}

return false;

}

function createModalKendoWindow(element, functionCallback) {

var frameId = "___kendoWindowModal_";

__modalKendoWindow = null;

__functionCallback = functionCallback;

var LINK = element.href;

var TITLE = $(element).attr("data-title");

var WIDTH = $(element).attr("data-width");

var HEIGHT = $(element).attr("data-height");

if (!(parseFloat(WIDTH) > 0)) {

WIDTH = "770px";

}

if (!(parseFloat(HEIGHT) > 0)) {

HEIGHT = "470px";

}

var kendoWindow = document.getElementById(frameId);

if (!kendoWindow) {

kendoWindow = $("<div>").attr({ id: frameId }).appendTo("body");

}

__modalKendoWindow = $(kendoWindow).kendoWindow({

title: TITLE,

modal: true,

width: WIDTH,

height: HEIGHT,

visible: false,

deactivate: function () {

this.destroy();

},

}).data("kendoWindow").center().refresh(LINK).open();

$(kendoWindow).css({ overflow: "none" });

return false;

}

function modalReturn(value) {

__modalKendoWindow.close();

if (value) {

if (__functionCallback) {

__functionCallback(value);

}

The application is being written with Visual Studio 2012 with a WebForms application.

So I set my menu to open the windows. This is the main page:

<script>

$(function () {

$('#tabMenu a').click(function (e) {

e.preventDefault();

kendoWindowFactory.createKendoWindow(this);

});

$(document).ready(function () {

$("#tabMenu").kendoTabStrip();

});

</script>

So I set the child pages (which are opened within kendoWindows using iframe) to open a modal window.
Fits a search window, for example:

<script type="text/javascript">

function returnValue(value) {

document.getElementById("<%= txtCodigo.ClientID.ToString() %>").value = value;

__doPostBack("Municipio.aspx", "txtCodigo_TextChanged");

}

$(function () {

$("#<%= btnConsultar.ClientID.ToString() %>").click(function (e) {

e.preventDefault();

window.parent.kendoWindowFactory.createModalKendoWindow(this, returnValue);

});

</script>

Every kendoWindow is created and removed dynamically.

To return a selection made in the modal window use this code:

<script type="text/javascript">

$(function () {

$("#grvMunicipio").kendoGrid({

columns: [

{ field: "Codigo", title: "Código" },

{ field: "Descricao", title: "Município" },

{ field: "Uf", title: "Estado" }

],

dataSource: {

pageSize: 15

},

sortable: true,

selectable: true,

pageable: {

refresh: true,

pageSizes: true

}

});

$('#grvMunicipio').dblclick(function () {

var Grid = $("#grvMunicipio").data("kendoGrid")

Grid.select().each(function () {

var dataItem = Grid.dataItem($(this));

RetornaValor(dataItem.Codigo);

});

</script>

I use a callback routine passed as a parameter to the main page, the JavaScript function created, which is to destroy the modal window and return the value to the desired field.

My problem is: When I open the modal window by button link child window, the child window is frozen.
I close the modal and I can no longer use the controls / window elements daughter.
However, when moving the child window with the mouse controls are released.

The child page now has no code in your code behind.

Can anyone help me with a particular problem?

From now on, thank you all!

Kendo UI for WEB

We are very interesting about the telerik products we have gone through the many kendo examples which provided in telerik official website as well as in other forums but we just get the simple staff.

We are planning to start a new web project with the MVVM frame work with Kendo . We are unable to find the complete real example for Kendo UI for web based systems as you have developed it for telerik Ajax(eg : sales Dash Board).

If it is their sample code please be kind enough to send us

We are very much interesting to get you feed back on this

Update Data Source on a button click event

We would like to update a data source when a refresh button is clicked. In my javascript file I have the following declared:

var seriesData1 = [{"UnitNumber":"1010", "percent":85, "PMTYPE":"ODOMETER", "CompCode":"000-003"}, {"UnitNumber":"1010", "percent":75, "PMTYPE":"Days", "CompCode":"000-005"}];

I have this defined in my index.html:

<script>
function createChart() {
$("#chart").kendoChart({
theme: $(document).data("kendoSkin") || "black",
dataSource: {
data: seriesData1

},
title: {
text: "PMs Due"
},
legend: {
position: "top"
},
seriesDefaults: {
type: "column"
},
series: [
{
name: "% Due",
field: "percent"
}
],
valueAxis: {
labels: {
format: "{0}%"
}
},
categoryAxis: {
field: "CompCode"
},
tooltip: {
visible: true,
format: "{0}%"
}
});
}
</script>

When I click on the refresh button I am changing the values as follows in my javascript:

seriesData1 = [{"UnitNumber":"1010", "percent":35, "PMTYPE":"ODOMETER", "CompCode":"000-060"}, {"UnitNumber":"1010", "percent":75, "PMTYPE":"Days", "CompCode":"000-005"}];

$(".chart").data("kendoChart").redraw();

All that has changed is the percent and comp code of the first record .

On first load data is displayed without error however when the button is clicked to redraw the graph, the data is cleared and nothing is updated leaving a blank chart.

Is there anything else that I have to do to update the data source?

Sample with Facebook Login (facebook jsdk + kendoui mobile)

Following is an example of using facebook login for your kendo mobile webapp

http://www.grapto.com/publication/314/416 (web browser)
http://www.grapto.com/mobile/publication/314/416 (mobile)

the workaround on function LogIn() is for iPhone pinned on homescreen webapps. It will ask for login without poping the safari browser.
you may remove this workaround if you don't want to run your app on iPhone homescreen. Keep it if you want to publish with phonegap or other tools.

contact me for any further thoughts or if you need help implementing your own facebook apps with kendoui.

Orphaned elements / Memory Leak in Grid using a filter

Hello, either there is a memory leak with grid's (when used with a filter) or I'm using it wrong. I'm hoping that I'm using it wrong! So I've created a jsfiddle that demonstrates the problem below. The problem seems to be that when i reload the grid (by removing the grid first) it seems to leave the hidden k-filter-menu behind in the dom. If you keep on clicking reload you will eventually run out of memory. You can best see the problem if you load up firefox + firebug. Inspect the grid and click reload, you'll notice the orphaned filter forms keep on adding up.

http://jsfiddle.net/nZ7j3/5/

ps. i didn't bother create a fiddle for it, but the same problem exists for any kendo object that maintains a hidden form element (i'm generalizing but i've definitely seen it on the DropDownList, ComboBox)

KendoUI grid not calling controller on batch save

Hi folks, I have been trying to figure out why my KendoUI grid will not call the controller when attempting to batch save. As part of my troubleshooting, I created a number of ActionResults with different parameters and breakpointing in each one, hoping that I would hit one of these breakpoints. No matter what method that I use in my view to call the controller to save, nothing happens.

I have two cascading Kendo DropDownLists (which work fine), and upon the user selecting an item in the second DropDownList, I populate a KendoUI grid via JSON. The user can then fill in the New Rate field to whatever they want, and finally click a save button to batch update. The user can increase (and later decrease, when I implement it) a percentage across the board via a TextBox and button.

I come from the ASPX and WinForms world, so jQuery and javascript in general are not my strong suits.

Here is the pertinent source code. I added some javascript alerts, to help troubleshoot. Note that the Kendo and jQuery scripts are referenced in a layout page as follows:
<script src="@Url.Content("~/Scripts/jquery-1.8.3.min.js")" type="text/javascript"></script>
   <script src="@Url.Content("~/Scripts/kendo.web.min.js")" type="text/javascript"></script>
