Hi,

How can we export a grid data to excel using Kendo grid for Angular?

Hi,
Is the option available to show an upload control inside a Grid cell? if not, that is doable through editing template. However, when submitting the data, how will the DataSource handle that?

Thanks

We are building a complex application that utilizes AngularJS for our Javascript and SPA framework, and using the Kendo UI controls for rich UI. Obviously, we are using the built-in AngularJS directives to render the Kendo components.

The problem is that we are encountering memory leaks when switching between views in the SPA, and these seem to be related to Kendo. The heap size keeps growing after every page that is navigated to, meaning that the components aren't being completely cleaned up when the view (and $scope) is being destroyed. 

For example, if we start at page A, navigate to page B, and then back to A, we can see in Chrome's Memory Heap Profile that Kendo is leaving behind a Detached DOM Tree for components in page B (see http://i.imgur.com/S2BlbKT.png). If I drill down into one of these trees, you can clearly see that these are Kendo widgets which are being left behind because of javascript references which are left behind (see http://i.imgur.com/tQ96CAz.png).

Further, looking at the page HTML, we can see that for widgets such as the Combobox and DatePicker, Kendo is leaving behind "k-list-container" divs in the DOM which are accumulating at the bottom of the SPA's html and are not being removed when a view is being unloaded / $scope is being destroyed (see http://i.imgur.com/hJWxlAq.png).

We've tried manually calling kendo.destroy(angular.element('#container')) when the $scope is being destroyed, however this doesn't seem to help at all with getting rid of the extra DOM elements or with freeing up the Javascript references to the widgets.

Aren't the widgets, when used in conjunction with the AngularJS directives, supposed to automatically clean themselves up when the $scope is destroyed?If not, please let me know how we can effectively unload the widgets so that we don't have traces of them left behind when we navigate from page to page.

I followed the instructions here:
http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/introduction

But, I am still getting the following error:
0x800a01b6 - Microsoft JScript runtime error: Object doesn't support property or method 'kendoDatePicker'

I think the problem is related to something VS2012 does when creating a Web Application for Mobile devices.

Here are the basic steps I followed:
Open VS 2012 > New Project > ASP.NET MVC 4 Web Application > Mobile Application > Then followed all the MVC 4 steps here (http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/introduction)

Any help will be appreciated. My code is below.

Hi,
We are hitting a scenario where the validation messages for an input field in a grid popup editor is not being removed when a valid value is entered. This can be replicated using the standard popup demo.

Popup editing demo

To replicate this you
- Click on add new record
- Delete the Units in Stock and press tab (you get the UnitsInStock is required error)
- Set the Units in Stock back to 1 (the default value) and press tab

The validation message is still shown even though the value is now correct. This only seems to happen if you set the value back to what it was before you deleted it. If you do the same steps above but change the number to 2 in the third step the message is removed correctly.

Is this a bug or is there anything we can do to force the validation to execute again and clear the message?

Hello, how do you select the next node, given that you have the selected node?  How do you select the previous item?

The treeview is loaded from a HierarchicalDataSource.

I get the selected node like this:

any help is appreciated,

Thanks.

Hello all,

I'm trying to bind my data (web api using entity framework 6) but still the generated chart shows no data only title and chart area.

I have something similier to this code:

<script type="text/javascript">
function createChart() {
$("#chart").kendoChart({
dataSource: {
transport: {
read: {
url: "http://localhost:*****/api/ISLFWs",
dataType: "json"
}
},
sort: {
field: "Year",
dir: "asc"
}
},
title: {
text: "Test"
},
legend: {
position: "top"
},
seriesDefaults: {
type: "column"
},
series:
[{
field: "ActualPSE",
name: "Actual PSE"
}, {
field: "TargetPSE",
name: "Target PSE"
},

{

}],
categoryAxis: {
field: "Year",
labels: {
rotation: -90
},
majorGridLines: {
visible: false
}
},
valueAxis: {
labels: {
format: "N0"
},
majorUnit: 10000,
line: {
visible: false
}
},
tooltip: {
visible: true,
format: "N0"
}
});
}

$(document).ready(createChart);
$(document).bind("kendo:skinChange", createChart);

</script>

Hi,

Is there a way to make one or more columns uneditable/readonly on an Grid that already has editable option enabled, and that it when trying to edit a row?

Your help is much appreciated.

In version 2014.3.1119 of Kendo UI I have a problem passing date value from view to controller, the  value passed to controller is {01/01/0001 12:00:00 a.m.}, however with the previous (2013.3.1119) version works as expected.

this my code inside parameterMap

for (var member in KPIDataEntry) {
          if (member == "Date") {
               result["KPIDataEntry[" + i + "]." + member] = kendo.toString(new Date(KPIDataEntry[member]), "G");
          }
          else {
              result["KPIDataEntry[" + i + "]." + member] = KPIDataEntry[member];
         }
}

thanks in advanced, and sorry about my english

Hi,

we're having trouble rendering nice Candlestick chart in some cases.

Specifically, for some values passed, chart is not "zoomed" in to better see difference between points but rendered from the '0' on value axis instead. For other cases, it's behaving as expected. To better illustrate, please see following dojo: http://dojo.telerik.com/AnOhe and see that value axis starts from '0' where it could start from '18' for example.

Is there a way to force chart to do this, instead of calculating valueAxis.max and valueAxis.min manually?

Thanks,

Dragan
