Issues with Grid Multiselect Editor Function using knockout bindings

So I've got a model passed in like so:

public class MainViewModel{

public IList<SubViewModel> SubViewModels;

}

public class SubViewModel{

public Guid Id;

public string Name;

public IList<Guid> CategoryIds;

public IList<CategoryType> CategoryTypes;

}

public class CategoryType {

public Guid Id;

public string Type;

}

Now in my javascript I take my model and convert:

var initialData = @Html.Raw(JsonConvert.SerializeObject(Model, new JavaScriptDateTimeConverter()));

var mainViewModel = new MainViewModel(initialData);

function MainViewModel(data) {

var mapping = {

'SubViewModels':

create: function(options) {

return new SubViewModel(options.data);

}

ko.mapping.fromJS(data, mapping , this);

}

function

SubViewModel(

var self = this;

ko.mapping.fromJS(data, mapping , self);

self.CategoryMultiSelect: function (container, options) {

$('<input data-bind="value:' + options.field + '"/>')

.appendTo(container)

.kendoMultiSelect({

autoBind: false,

dataTextField: "Type",

dataValueField: "Id",

dataSource: options.model.CategoryTypes

});

}

}




ko.applyBindings(mainViewModel, $("#MainViewModel")[0]);

Now when I call the editor function in the grid:

<div id="subviewModelGrid" data-bind="kendoGrid: {

data: $data.SubViewModels,

sortable: true,

scrollable: false,

           editable: true,

pageable: { pageSize: 10, input: false },

columns: [{

field: 'CategoryIds',

title: 'Categories',

width: '300px',

editor: $data.CategoryMultiSelect

}]}"/>

After click on the column I get the following error:

Uncaught TypeError: Object f7ae02dc-c8a7-f112-e043-991018ace7d8 has no method 'get' kendo.web.min.js:12

S.widget.value.m.extend.refresh kendo.web.min.js:12

r.incell.r.update.n.wrapper.on.on.n.timer kendo.web.min.js:17

p.event.dispatch jquery-1.8.2.min.js:2

g.handle.h

Which is referring to the only id in the array of 'CategoryIds'. I'm putting this question in Multiselect because I am using editor functions for several other columns and not having this issue. Any thoughts?

Binding ListView directly to a list of objects

I am trying to use the MVC extensions to bind directly to a list of objects. The data is part of the model that is passed to the view. I don't want the list view to make an extra call just to get data that is already available. I am trying to use a combination of BindTo() and ClientTemplateId(), but the resulting list is always empty.

Checkbox on IE8,9 and 10

Hello,

We are having some issues with checkbox on IE. (working correctly on Chrome and FF)

When we use IE, it always says that the "checkbox" is mandatory, as soon as we check/uncheck it.

Here is the code :
$("#grid2").kendoGrid({
dataSource: {
error: errorHandler,
transport: {
...
parameterMap: function(options, type) {
return JSON.stringify(options);
}
},
schema: {
data: "data",
total: "total",
model: {
id: "id",
fields: {
initials: { type: "string",
validation :{
required: true,
pattern : "\\w{0,5}",
"data-pattern-msg": "Maximum 5 chars"
}
}, active: {type: "boolean", defaultValue: true},
....
columns: [ {
field: "initials",
title: "${user_list_initials}",
width: "10%"
}, {
field: "active",
title: "${user_list_active}",
width: "10%",
template: "<input type='checkbox'#= active ? 'checked=checked' : '' # disabled='disabled' /> "
},

This happens with the JSP Wrapper, or when using javascript aswell.

Any hints why it does that ?

The only difference compared to one demo I've seen is that I override the template to display it as a read-only checkbox.

Thank you in advance

Navigator display problem with negative values

Hi there,

I'm using he StockChart for displaying a line chart on top of the navigator. It generally works well, but when there are negative values within my Json data, the navigator doesn't mask the unselected data correctly and it overlaps the labels below. What can I do about it? Please see the attached images for an example.

Regards,
Robert

Hiding empty menu items

Hi,

I'm using the Kendo.Mvc.Menu with a site map and security trimming.
My problem is that when all sub items of a menu item are trimmed, the parent item is still being displayed.

I've found an answer to a similar question regarding the Telerik.Menu, on this thread.
However, I could not find the equivalent in the Kendo framework to this line:

<% var navAuthorization = Telerik.Web.Mvc.Infrastructure.ServiceLocator.Current.Resolve<Telerik.Web.Mvc.Infrastructure.INavigationItemAuthorization>(); %>

Best regards,

Assaf

Add a corporate logo to navbar

Hi - I have a requirement to show our corporate logo from every view, and their preference is to show it in the left-side area of the navbar. I have it showing up, but it is not vertically centered, and I have tried a number of things. I've tried vertical-align:middle, and margins:auto, but neither have worked so far:

<header data-role="header">
<div data-role="navbar">
<img id="corp-logo" src="images/app/corp-logo.png"
data-align="left" style="width:120px;height:30px;vertical-align:middle;"/>
<span data-role="view-title"></span>
</div>
</header>

and...

<header data-role="header">
<div data-role="navbar">
<img id="corp-logo" src="images/app/corp-logo.png"
data-align="left" style="width:120px;height:30px;margin: auto .3em auto .3em;"/>
<span data-role="view-title"></span>
</div>
</header>

What would be preferred approach approach for vertically aligning a logo image within the navbar area?
Thanks, Jim Wangler

Edit button returns json but popup edit isn't working?

Hi all. I'm new to the JS/JQuery/AJAX world & new to Kendo controls as well.

Not sure what's going on and would appreciate any help. My grid displays with an edit and delete button. Both buttons hit the controller actions as expected and the delete does, in fact delete. However it, it returns to a blank page instead of a refreshed grid, and my edit button returns raw JSON to an empty view. I'm guessing I don't have the grid wired correctly so that it know's how to catch the pass. Here's the code in my partial view. I commented out some columns that I don't need to see until the edit screen.

Any ideas? TIA

Show multiple series value in a CategoryAxis CrossHair Tooltip.

Hi,
I've been able to create a chart that fits my need except for one requirement which is to show all the series value in a single tooltip (CategoryAxis CrossHairToolTip).

I have 4 series (Weight1, Time1, Weight2, Time2) and 1 category (Period). By default i can easily show the CategoryAxis value in the CategoryAxis CrossHair Tooltip, but what i want to do is show the value of Weight1, Time1, Weight2 and Time2 in that tooltip.

Here is the code that show the Category value. and in comment what i would like to show instead.

Thanks in advance for your help.

<%: Html.Kendo().Chart<Data.DonneeChart>()
