I'm using a Kendo UI Bar chart and a json file with some dummy data (see attachment)
I needed to group this data, but I repeat this graph for each group, and I will show only the chart of that group.
a picture is added to make it more clear.
Is this possible to do this with Kendo UI or is there another way to do this?

(Crosspost from https://stackoverflow.com/questions/23188715/getting-list-of-dates-in-view-for-kendo-ui-calendar)

How can I get a list of the dates currently visible in Kendo UI Calendar? For example, the view for April 2014 includes dates from 30th March to 10th May, and I need a reliable way to get a list of those dates, even when changing month to June, for example.

Is it possible using the multi select dropdown list to select multiple items at once by pressing and holding the "ctrl" key on the keyboard and selecting items from the drop down at once?

If yes, can you please share a small code snippet?

Thanks in adv.

Hi,

Kendo Menu stop working after upgrading Kendo from 2013.3.1119 to 2013.3.1324.
Please go through plunkers and try out. Some times you'll observe that sub menu not displayed on hovering when we clicked on parent menu.
1. http://plnkr.co/edit/JW0rn48s6AAJPgUPlAmr?p=preview - Not working on version 2013.3.1324
2. http://plnkr.co/edit/uhdwCUbIjONQcOKNq56A?p=preview - Working on version 2013.3.1119


Please let me know if we have any workaround to fix this issue on 2013.3.1324?

Hi,

I am trying to work on the grid like below,

 basically i give a checkbox to user, when it is not checked, the grid only display data from URL1,
but if the checkbox is checked, it merge 2 json data and display the comparison of URL1 and URL 2

<label><input type="checkbox" name="compCB" id="compCB">Enable Compare</label>
<div id="grid" style="height: 365px"></div>
<script>
$(document).ready(function () {
  var url1="http://XXXXXXXXX/clients/1";
  var url2="http://XXXXXXXXX/clients/2";
  var J1=null;
  var J2=null;
  var Jdata;
  var toCompare;
  loadData('init');

  function loadData(act){
    toCompare =$('#compCB').is(':checked');
      if(act=='init'||act=='reload'){
        $.getJSON(url1, function(jd) {
          J1=jd;
          meargeData();
        });
      };
      if(toCompare){
        $.getJSON(url2, function(jd) {
          J2=jd;
          mergeData();
        });
      }else if(act='toggle'){
        J2=null;
        mergeData();
      };
    };
    function mergeData(){
      if(J1!=null&&(J2!=null||!toCompare)){
        if(!toCompare){
          Jdata=[{
            clientId: J1.clients[0].clientId,
            name: J1.clients[0].name,
            status: J1.clients[0].status
          }];
        }else{
          Jdata=[{
            clientId: {
              C1: J1.clients[0].clientId,
              C2: J2.clients[0].clientId
            },
            name: {
              N1: J1.clients[0].name,
              N2: J2.clients[0].name
            }, 
            status: {
              S1: J1.clients[0].status,
              S2: J2.clients[0].status
            }
          }];
        };
        genGrid();
      };
    };
    function genGrid(){
      if(!toCompare){
        RT='<tr data-uid="#= uid #"><td>#: clientId #</td><td><strong>#: name #</strong></td><td style="text-transform:lowercase;">#: status #</td></tr>';
        ART='<tr data-uid="#= uid #" style="background-color:rgb(255,200,255)"><td>#: clientId #</td><td><strong>#: name #</strong></td><td style="text-transform:lowercase;">#: status #</td></tr>';
      }else{
        RT='<tr data-uid="#= uid #"><td>#: clientId.C1 #<br/>#: clientId.C2 #</td><td><strong>#: name.N1 #<br/>#: name.N2 #</strong></td><td style="text-transform:lowercase;">#: status.S1 #<br/>#: status.S2 #</td></tr>';
        ART='<tr data-uid="#= uid #" style="background-color:rgb(255,200,255)"><td>#: clientId.C1 #<br/>#: clientId.C2 #<br/></td><td><strong>#: name.N1 #<br/>#: name.N2 #</strong></td><td style="text-transform:lowercase;">#: status.S1 #<br/>#: status.S2 #</td></tr>';
      };
      $("#grid").kendoGrid({
        dataSource: {
          type: "json",
          data: Jdata,
          pageSize: 3,
        },
        groupable: true,
        sortable: true,
        resizable: true,
        columnResizeHandleWidth: 6,
        pageable: {
          refresh: true,
          pageSizes: true,
          buttonCount: 5
        },
        columns: [{
          title: "ID",
          width: 200
        }, {
          title: "Client Name",
          width: 250
        }, {
          title: "Status"
        }],
        rowTemplate: RT,
        altRowTemplate: ART
      });
    };
    $('#compCB').change(function(){
      loadData('toggle');
    });
  });
</script>

Now, I am trying to do it in the MVVM structure, the first problem I face is how do I change the  rowTemplate and altRowTemplate dynamicly?


 

Hi!
I have a listview containing a template with a sparkline in.
I have around 15 items in the listview and it takes about 8 seconds to load the page and create all the sparklines.
Today, nothing is shown before all sparklines are created (i'm using the data-init event).
It feels like the application has stoped responding so I want to change this behaviour.

I want the page to load faster and after it has finished loading, it start to create the sparkline asynchronisly (like ajax updates)
Is this possible?

Regards,
Per

I have a view which has a listview inside. When I click on an item a ModalView which shows the detail is opening. When I click remove, the item is being removed. 

My problem is, when I click on an item inside the listview, the dialog is openning again with the related data but the button is not enabled.

What am I doing wrong?

function closeModalViewRemove() {
   
  $("#modalview-app-remove").kendoMobileModalView("close");

};


function deleteFromJson() {
 
  var $app_list = localStorage.getItem('LsAppList');
  var AppListJson = JSON.parse($app_list);

    jQuery.each(AppListJson, function(i, val) {
                                         if (AppListJson[i].extapp_id == appdetail.get("addAppId"))
{    
    AppListJson.splice([i], 1);
$app_list = JSON.stringify(AppListJson);
localStorage.setItem('LsAppList',$app_list);
closeModalViewRemove();
 
}
}); 


}

Hi,

I am trying ‘Save all changes with one request’ (http://www.telerik.com/support/code-library/save-all-changes-with-one-request) solution. I modified UpdateCreateDelete() method to return  modified data as response to the request. Now I want to make datasource and grid update
themselves smoothly without the additional roundtrip caused by calling read().

Please suggest how I may do this.


 

Hello
I know there is currently no clustering support for DataViz Map.

I would like to ask about possible solution to use 3rd party library like Leaflet or OpenLayers. I've tried to find in documentation place where I can put my code to display cluster. I cannot find dataBound event like in other controls to make operations on data source.

To clarify. I want to use DataSource to download remote data necessary to display complex tooltip and cluster. So I need the place on map widget where I can start rendering such data using 3rd party library.

Kind Regards
Marcin

Hi all,

I am using the Kendo controls in a MVC4 project. In one of the pages I'd like to get drag and drop functionality just exactly like in this Kendo ASP.NET Control:
https://demos.telerik.com/aspnet-ajax/listview/examples/itemdragdrop/defaultcs.aspx


Have anyone implemented something similar??

Cheers
