No parameterless constructor defined for this object

Hi

We are getting the error "No parameterless constructor defined for this object" when we try to bind collection to the Kendo grid and obviously the business objects that we have in our business layer has private constructors and it worked fine with Telerik.

Here is the stack trace of the error

Line 171:    {

Line 172:        //@(Html.Kendo().Grid<City.Australia.Framework.BL.UserInfo>()

Line 173:        @(Html.Kendo().Grid(Model.Users)

Line 174:            .Name("UserGrid")

Line 175:            .EnableCustomBinding(true)

Source File: d:\Development\City.Australia.Admin\City.Australia.Admin\Views\User\Search.cshtml Line: 173

Trouble using buttongroup to switch between two views

I am trying to use the buttongroup to switch between two views that contain charts on mobile device. However, my code is not working. All that is rendered are the two buttons and the nav bar at the top. The charts are not showing up. I tried the code for drawing the charts in stand alone views and that worked fine. I am attaching my code snippets. Please let me know what is the best approach for this.

Thanks,
Anu

Kendo UI Grid Filter not working

I am just starting with Kendo UI. I have a .NET MVC Razor project that will include a Kendo Grid. My page loads fine and looks good-the data is in the grid, but I have two issues:
(1) when I click the "filter" icon, nothing happens (no pop-up, nothing)
(2) when I run the page I get an error in visual studio inside the kendo.all.min.js file (Error: Microsoft JScript runtime error: Object doesn't suport this action. Code highlighted reads "d.transport=new n.data.transports[a.type](c(h,{data:i}))" Running in firebug gives this error: "n.data.transports[a.type] is not a constructor"

I am using a Model that is of type List<CustomViewModel>. I have added the following scripts and css to my _Layout partial view:
    <link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
    <link href="@Url.Content("~/Content/kendo.common.min.css")" rel="stylesheet" type="text/css" />
    <link href="@Url.Content("~/Content/kendo.default.min.css")" rel="Stylesheet" type="text/css" />

    <script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/modernizr-1.7.min.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/jquery.min.js")" type="text/javascript"></script>
    <script src="@Url.Content("~/Scripts/kendo.all.min.js")" type="text/javascript"></script>

(I tried using "kendo.web.min" and "kendo.aspnetmvc.min" in the place of "kendo.all.min" and I get the same result, but the error is in kendo.web.min.js)

My page looks like this:

@model List<CustomViewModel>
...
@(Html.Kendo().Grid(Model)
    .Name("applicantGrid")
    .Columns(columns =>
        {
            columns.Bound(p => p.ApplicationID);
            columns.Bound(p => p.FirstName);
            columns.Bound(p => p.LastName);
        })
    .Sortable()
    .Filterable()
    .Pageable()
)

My View Model looks like this:

    public class CustomViewModel
    {
        [ScaffoldColumn(false)]
        public Guid CustomViewModelID { get; set; }

        [Display(Name = "First Name")]
        public string FirstName { get; set; }

        [Display(Name = "Last Name")]
        public string LastName { get; set; }
    }

No records display message

Hi,

If a grid has no records I do not want to display the grid at all (including the headers) but would like to display a text message instead. Is this possible using Kendo?

Thanks

Grid List?

I am creating an application that needs to have multiple "image buttons" that fills the screen and looks like the Andriod Grid List. When the user clicks the image, it goes to another page. What is the best approach to creating this functionality using Kendo controls?

Thanks!

[Solved] New Grid Features in 2.710?

I upgraded to 710, and I see some changes to the page turners, but I have not figured out how the USER is able to do these new features:

Implement "Refresh" button in the pager
Allow the user to change the page size of the grid
Ability to change the current page by typing it in a textbox

I also an very intrigued by this feature, can you explain what it is (I am already adding double click to the rows by:

Ability to attach click handler to custom commands

$('#gridWidget tbody > tr[data-uid]').dblclick(DisplayItemDetails);

Finally, I was given this code by Telerik for collapsing all the groups and expanding them. It stopped working in 2.710, I can fix it, but is there a way that will be a safe fix for future versions?

function collapseAll() {

$("#gridWidget").find(".k-icon.k-collapse").trigger("click");

}

function expandAll() {

$("#gridWidget").find(".k-icon.k-expand").trigger("click");

}

remote xml datasource (prestashop webservice)

Hi, i'm new to this forums, and i'm testing your fantastic jquery library.
i've looking for a solution in the forums, but no one found.
I'm using prestashop webservices and i have this code:(modified from one sample)

<!DOCTYPE html>

<html>

<head>

<title>Binding to remote data</title>

<link href="../../content/shared/styles/examples-offline.css" rel="stylesheet">

<link href="../../../styles/kendo.common.min.css" rel="stylesheet">

<link href="../../../styles/kendo.default.min.css" rel="stylesheet">

<script src="../../../js/jquery.min.js"></script>

<script src="../../../js/kendo.web.min.js"></script>

<script src="../../content/shared/js/console.js"></script>

</head>

<body>

<a class="offline-button" href="../index.html">Back</a>

<div id="example" class="k-content">

<div id="grid"></div>

<script type="text/javascript">

$(document).ready(function() {

$("#grid").kendoGrid({

dataSource: new kendo.data.DataSource({

transport: {

// specify the XML file to read. The same as read: { url: "books.xml" }

read: "http://mykey@localhost/orion/api/customers/1"

},

schema: {

// specify the the schema is XML

type: "xml",

// the XML element which represents a single data record

data: "/prestashop/customer",

// define the model - the object which will represent a single data record

model: {

// configure the fields of the object

fields: {

// the "title" field is mapped to the text of the "title" XML element

elid: "id/text()",

// the "author" field is mapped to the text of the "author" XML element

nombre: "firstname/text()",

// the "url" field is mapped to the text of the "url" XML element

apellidos: "lastname/text()",

}

}),

scrollable: false,

sortable: true

});

</script>

</div>

</body>

</html>

and does not work, the screen is blank, but if i change:

read: "http://mykey@localhost/orion/api/customers/1"

with:

read: "1.xml"

that contains de content of "http://mykey@localhost/orion/api/customers/1", that's:

<prestashop>

<customer>
