Editable Grid manual dataItem.set() for checkbox binding is slow/delayed

As I have posted here I have a problem with setting dataItem.set() manually.

I have an editable Kendo Grid that may have a column with a checkbox to change a boolean value. I have used this solution proposed by OnaBai that is working perfectly!

The only problem is that the checkbox value change is too slow. When user clicks it, it takes about 1 second to change. I realize that the dataItem.set() method is responsible by this delay.

My grid has a considerable amount of data. About 30-40 columns and 300+ lines. It is defined as follows:

$("#mainGrid").kendoGrid({

dataSource: dataSource,

pageable: false,

sortable: true,

scrollable: true,

editable: true,

autoBind: false,

columnMenu: true, // Cria o menu de exibição de colunas

height: getGridHeight(),

toolbar: [/* hide for brevity */],

columns: [/* hide for brevity */],

dataBound: function() { /* hide for brevity. */},

edit: function() { /* hide for brevity. */}

});

Another detail is that, when dataItem.set() is called, it calls dataBound() event but that is not causing the delay. Grid's edit() method is not being called on this process. I don't know if worths to post dataSource code.

Any help will be very appreciate. Thank you in adv.

Bug report, in categoryAxis.maxDateGroups

Let's say I have maxDateGroups set to 10. If I have data going from January 20 to November 15, this data covers less than 10 months, however my chart will display 11 bars, one for each month from January through November. Same behavior with weeks, and probably all the other baseUnits.

[Solved] MVVM - Multiple Series with category axis

I have a chart with multiple series (See attached).
I want to list the dates from the series available in the same data.
The problem im experiencing is selecting a category axis value. Setting it on any of the series causes all of the series to not show, but the dates do for all rows.

Json data:

01.[{

02."InStore":{"OrderCount":0,"Sales":0,"Canceled":null},

03."Collection":{"OrderCount":31,"Sales":28290,"Canceled":null},

04."Delivery":{"OrderCount":10,"Sales":15883,"Canceled":null},

05."Combined":{"OrderCount":41,"Sales":44173,"Canceled":1},

06."Date":"\/Date(1381964400000)\/"},

07.{"InStore":{"OrderCount":0,"Sales":0,"Canceled":null},"Collection":{"OrderCount":49,"Sales":31990,"Canceled":null},

08."Delivery":{"OrderCount":18,"Sales":36463,"Canceled":null}

09.…

10.}]

Within this data the chart has 4 series:
Combined.OrderCount;
Collection.OrderCount;
Delivery.OrderCount;
Combined: Sales

for those series I want to use the 'Date' field.
The HTML looks like this:

01.<div class="chart-wrapper" data-role="chart"

02. data-title="Order Details"

03. data-theme="bootstrap"

04. data-legend="{ position: 'bottom' }"

05. data-series-defaults="{ type: 'line' }"

06.@* data-category-axis="{

07. field: 'Date',

08. baseUnit: 'day',

09. type: 'date',

10. labels: {

11. rotation: -90

12. },

13. majorGridLines: {

14. visible: false

15. }

16. }"*@

17.@* data-category-axis="{

18. categories: [1,2,3,4,5,6,7]

19. }"*@

20. data-category-axis="{

21. labels: { rotation: -90, template: 'Hello' }

22. }"

23. data-value-axis="[

24. { name: 'orderCount', title: { text: 'Orders' } },

25. { name: 'sales', title: { text:'Sales' } }

26. ]"

27. data-tooltip="{

28. visible: true,

29. template: '<div>#: kendo.toString(dataItem.Date, \'dddd\') # #: kendo.toString(dataItem.Date, \'d\')#</div><div>Order Count:#: value #</div>'

30. }"

31. data-group="{field:Date}"

32. data-series="[

33. { 'name': 'OrderCount', 'field': 'Combined.OrderCount', 'axis': 'orderCount' },

34. { 'name': 'Delivery', 'field': 'Delivery.OrderCount', 'axis':'orderCount', 'type': 'column', 'stack': 'true' },

35. { 'name': 'Collection', 'field': 'Collection.OrderCount', 'axis': 'orderCount', 'type': 'column', 'stack': 'true' },

36. { 'name': 'Sales', 'field': 'Combined.Sales', 'axis': 'sales', 'type': 'area' }

37. ]"

38. data-bind="source: dataSource">

39. </div>

Any ideas? Setting the categories manually works but I don't want to do it this way as it will be more to maintain and more effort over more charts.

Additionally - why does the legend disappear after the chart gets its data?

Thanks, Matt

Kendo Grid Selectable not working when using Chart on same page

I have a very silly problem.

I have a Kendo Grid with Detailed View that can expand/collapse, it works flawlessly and looks good. The problem is that as soon as I insert a Kendo Line Chart to the page the rows in the Grid can no longer be selected, also not expanding. I t works well without the Chart within the same page.

I´ve checked the console of Firebug and that does not display any errors. I also can not detect any events when clicking row within the grid. It simply will not work.

Do you have any thoughts? Does Kendo Grid and Chart not work when used on the same page?

Thank you.

Possible to Post Files to Controller via jQuery instead of through the .Save Action?

Hi,

I'm looking to use the Kendo Upload control to Import vCards onto a Contact Creation page. Since I want to return a PartialView, and populate a Div's .html attribute, I'd like to do this as a jQuery Post like I've outlined below:

@(Html.Kendo().Upload()

.Name("vCard")

.Async(a => a

.Save("UploadContact", "Contacts") /*Don't really need this if I can post via jQuery */

.AutoUpload(true)

)

.Events(events => events

.Select("onSelect")

.Upload("onUpload")

)

.ShowFileList(false)

.Multiple(false)

)

function onUpload(e) {

var upload = $("#vCard").data("kendoUpload");

var files = upload.files;

var serialized = "vCard=" + files;

$.post("/Contacts/UploadContact/", serialized, function (returnHtml) {

//alert(returnHtml);

$("#ContactContainer").html(returnHtml);

});

My issue is that I am constantly getting a null object when posting to /Contacts/UploadContact using jQuery.

Is there any way to pass the entire file list (including FileStream) back to the controller from jQuery like I've outlined in the "onUpload" method?

Any help would be greatly appreciated.

Thanks,
Landon

Upgrade Changelogs?

I tried to upgrade from v2013.2.716 to v2013.2.918 (kendo.all.min.js) and ran into a few issues. My general question is whether there is a doc that provides more detail on the changes made, outside of the readme that just lists that a fix was applied with not much detail on how. Here are the two major issues I've seen and I've since rolled back to 716 since I don't have time to troubleshoot the issues right now.

View events:event objects always return empty objects. event.view and the other framework params are undefined in the show, init, and hide callbacks.
Mobile Listview: I have a detailbutton in my template and there an extra icon span with the same detail icon is being added to my li. Below is my template

01.<script id="tmp-favorite" type="text/x-kendo-template">

02. # var bool = category.toLowerCase().indexOf("documents")<0 #

03.

# var path =  !bool && ThumbnailImage && ThumbnailImage.indexOf("data:")<0?"data:image/jpeg;base64,"+data.ThumbnailImage:data.ThumbnailImage #

04. <img src="#: path #"/>

05. <div class="li-text">

06. <p class="li-title">#: t # (#: FavoriteName #)</p>

07. <p class="li-desc">#: FavoriteType #</p>

08. </div>

09. <span data-role="detailbutton" data-icon="isfavorite" class="item-favorite-status alt-btn right-1"></span>

10. </script>

[Solved] Avoid a tabstrip to be active, or make one active

Helly Guys,

I have two tabstrip, but I want the first one to always appear as active. Here is the excerpt of the code below (that doesn't work).

<div data-role="footer" data-align="left">

<div data-role="tabstrip" data-align="left">

<a href="#results" data-icon="globe" data-transition="slide:top" id="resultstab"><div id="results_count_display" style="color:white" class="km-text">Loading..</div></a>

<a href="#filter" data-icon="settings" data-transition="slide:top" id="settingstab"><div class="km-text" style="color:white">Filter</div></a>

</div>

<script>

$('#settingstab').bind('click', function () { $('#settingstab').removeClass('km-state-active');$('#resultstab').addClass('km-state-active'); });

</script>

</div>

I want that when "settingstab" is clicked on: the "resultstab" flips back to active.

Thanks.
