Pie Explode

Hello...I'm using the Razor syntax for creating my pie chart and am having problems figuring out how to explode a slice using a databound pie chart. Here is the code that I thought would work...the object that is feeding the Pie has 2 attributes: Label holds the name and Value holds the value.

@(Html.Kendo().Chart<InfoSource.Requests.Models.Graph>()

.Name("myallocation")

.Title(title => title

.Text("MY ALLOCATION")

.Font("16px Oswald")

)

.Theme("Silver")

.Legend(legend => legend

.Visible(false)

)

.ChartArea(chartArea => chartArea

.Background("transparent")

)

.DataSource(ds => ds

.Read(read => read.Action("dMyAllocation", "Dashboard", new { area = "InfoSource.Metrics" }))

)

.Series(series => {

series.Pie(model => model.Value, model => model.Label, null, model => model.Label == "Unassigned" ? true : false)

.Labels(labels => labels

.Template("${dataItem.Label}")

.Visible(true).Position(ChartPieLabelsPosition.InsideEnd)

);

})

.Events(events => events

.SeriesClick("myallocationClick")

)

.Tooltip(tooltip => tooltip

.Visible(true)

.Template("${dataItem.Label} - ${value}%")

)

.HtmlAttributes(new { style = "max-height: 300px;" })

)

From what I can understand, the series syntax includes on option for true/false if the pie should explode or not. I have set mine up using the Label text so that if the Label text is "Unassigned", the pie piece should explode. This is not happening however.

Can you let me know if my syntax is correct or not? Thanks.

Problems with the Grid and MVVM

Hi,
I'm very new to the MVVM framework and I'm running into problems with the grid. If I set a static height for the grid the content area including the scroll bar does not respect the height. The outline of the grid is correct. I thought at first it was an issue with the parent div being set to display:none but I removed that and it still happens. When I first load my grid it is loading one record and the scroll bar appears just slightly larger than that 1 row. When I click the checkbox above it forces it to load 3 records and the content area/scroll bar remain at the same height and you can scroll it. If I remove the static height the grid grows as more records are loaded which make the scroll bar useless because the grid is always showing all the records loaded. I have attached a couple of screen shots. Am I the only one having this issue?

Thanks for any help that can be provided,
Casey

This is a single page app so each page starts off as it's own Div

<div id="CustomerListPage" style="min-width: 500px">

<div style="width: 600px; margin-left: auto; margin-right: auto; text-align: right">Include Inactive?<input id="IncludeInactiveCheckBox" type="checkbox" data-bind="checked: includeInactive, events: {click: includeInactiveChanged}" /></div>

<div id="CustomerListGrid" style="width: 600px; height:300px; margin-left: auto; margin-right: auto; margin-top: 10px" data-role="grid" data-selectable="row" data-columns=

'[{"field":"id", "title":"ID", "width":50}, {"field":"FullName", "title":"Name"}, {"field":"MailingAddressCity", "title":"City", "width":150}, {"field":"MailingAddressState", "title":"ST", "width":50}]'

data-bind="source: customers"></div>

</div>

Here is the view model that controls that page

var CustomerListViewModel = kendo.observable({

// properties

customers: [],

includeInactive: false,

includeInactiveChanged: function (val) {

this.load();

},

load: function () {

var self = this;

var dto = new DTO(true, '', new Object({ includeInactive: this.get("includeInactive") }));

$.ajax('SysUserWebService.asmx/GetCustomerList', {

data: JSON.stringify({ dto: dto }),

type: 'post', contentType: 'application/json',

success: function (result) {

if (result.d.success) {

self.set('customers', result.d.payload);

} else {

alert(result.d.message);

};

}

});

}

});

My binding occurs with the page's hash change

// routes the application based on hash changes

var HashChange = function () {

HideAllPages();

var query = location.hash.split("?");

var hash = query[0];

switch (hash) {

case '':

location.hash = '#MainMenu';

break;

case '#MainMenu':

$('#MainMenuPage').show();

break;

case '#CustomerList':

$('#CustomerListPage').show();

kendo.bind($('#CustomerListPage'), window.CustomerListViewModel);

window.CustomerListViewModel.load();

break;

case '#CrewList':

$('#CrewListPage').show();

break;

case '#History':

$('#HistoryPage').show();

break;

};

[Solved] Second elment no binding in template

I was playing around creating a template and came across this problem. The template has two element, first with data-role of numeric text box, the second with grid. The first element binds correctly, but the grid does not show up.

I created a jsFiddle that demonstrates the behavior. I had also tried making the items array an observable with no luck.

Default column grouping name

I have a grid setup with one of the columns as : {title:"First Name", field:"FIRST_NAME", sortable:true}

When I drag this column up to the "grouping" section, it displays as "First Name" which is expected. Now if I add the option "hidden:true" to the above column and set a default grouping on this field, it displays "FIRST_NAME" instead. Is there something I'm missing to get hidden columns that are in a default grouping to display as their title and not the actual field ?

[Solved] Infinitely Growing ActionSheet

Here's an example of what I mean. Just open and close the actionsheet several times.
http://jsfiddle.net/RodEsp/r5eCm/

As far as I can tell this behavior can go on forever. I don't know if I'm doing something wrong.

Anyways, I noticed that the issue is that the width of the .k-animation-container grows every time it is opened and closed. I think it might have something to do with the "left:" css style that also changes when the container is opened and closed.

An easy way to see this is by opening the actionsheet, right clicking on the title and inspecting the element. Then just find the div with the .k-animation-container class above actionsheet <ul>. As you open and close the sheet you'll see the width of the container grow.

It is possible to fix this by setting .k-animation-container { width:100% !important; height:100% !important; } (In non iOS platforms the height also grows). But this breaks other elements that depend on the .k-animation-container such as comboboxes.

Hope you guys can help me out with this one!

kendoWindow custom action button click triggers browser window popstate handler

Hello,

Can anyone confirm the kendoWindow custom action, as shown below, triggers the browser window's popstate event handler?

 $("#window").kendoWindow({
      actions: ["Custom", "Minimize", "Maximize", "Close"],
      title: "Window Title"
  }).data("kendoWindow").wrapper.find(".k-custom").click(function(e) {
      alert("Custom action button clicked");
      e.preventDefault();
  });

It does in my case. Here's the relevant popstate code:

function popStateHandler(e) {

var State = e.state;

if (State != null) {

console.log(State);

switch (State.stateTitle) {

case "Landing Page":

console.log('transitioning to landing page ...');

// show the content div and hide the hide the login panel

//

Transitions.PrimaryElementTransitions.HideLoginPanel();

break;

default:

break;

} // end switch ...

} else if (window.processingLogin == true) {

console.log('Processing login flag is true.');

window.ProcessingLogin = false;

} else {

console.log('transitioning to login state ...');

// show the login panel and hide the content div

//

Transitions.PrimaryElementTransitions.ShowLoginPanel();

}

// Attach the window.history popstate event handler defined above.

//

window.addEventListener("popstate", popStateHandler, false); // end function definition and addEventListener method invocation ...

Thanks,

Dan

MVVM in templates for ListView and Grid editing

Hello,

I use MVVM style databinding in my templates for the ListView and Grid widget (in case of the Grid I have a template per column).

That works fine, also when switching to edit mode.

The problem is that when I switch back from edit mode to readonly. I can see in the debugger that the template is applied again, but the MVVM binding is not done, so no data is displayed. Using a regular template (no MVVM) would work fine.

(Using Kendo version 2012.1.710)

Regards, Jaap
