I am using AngularJS Directives for Kendo UI 2014.3.1119, using ASP.NET Web API on .NET 4.5.2.
The Kendo UI Demo page for TreeList with AngularJS does not seem to fit in my scenario.
I've an AnguarJS SPA that uses Kendo UI Directives.

I've an existing HTML page containing a simple HTML table powered by ngRepeat.
This HTML is bound to an existing AnguarJS controller.

Until now, I have been using standard AngularJS $http Service like below that I'd use to get data from server : ( not OData, just regular JSON )

My goal :
========

Was to actually enable grouping in the table, and looking that the demo TreeList control seem to be the one I wanted to use, as I the records are read-only.
At the end of the post I've also posted the code that I've tried so far and it did seem to hit the server


but I am getting the error in browser console which reads :


"TypeError: Cannot read property 'toLowerCase' of undefined"


ng Controller :



ng Service :


Here is what I've tried so far :

I do not prefer re-creating a new service file for an existing service but I created one for test anyway. Below is how it looks :


Then in my controller :


And finally in my HTML :



My Questions :

1. How can I fix this ?
2. What is the most elegant solution ?
3. Would not that be possible to reuse the existing Angular Service that I've ?

i am using binding to local data of Grid widgets. i need to add functionality for click event in table cell like open a pop-up window on clicking the cell. so I like to assign class or id to dynamically created table rows and columns. How to i do this?
Thanks - Khara

Every time I do a paging request, I get this in the console:

Hi,

I have successfully implemented the Scheduler in an application with the use of the online examples. After running it for a few weeks, the customer requested a new overview of all scheduler events.

Therefore I have created a simple Kendo gridview that lists all user events, with a toolbar that contains the CRUD commands.
When the user clicks the edit button, a popup appears and the same (custom) schedule edit screen from the schedule page is shown. However, if the user clicks the save/update button, the recurrencerule property from the object is always null when sent to the server. All other properties are filled in.

Since I'm reusing my customeditortemplate I thought it would work without modification, but it appears I'm missing something.

I've found a small bug in the grid which has an impact on sorting.
To reproduce this issue, execute the following:

Create a grid that allows SingleColumn sorting. DO NOT SET the following:

JavaScript
sortable: { mode: 'single' }

If configured like above, you won't be able to reproduce the bug.
It should be configured the following way:

JavaScript
sortable: true

If you configure the Grid with the MVC HtmlHelper (.Sortable(a => a.SortMode(GridSortMode.SingleColumn)), you will get the sortable: true as Javascript output.

- Enable the column menu
- Sort a column
- Sort another column by using the column menu (use the small arrow).

You have now achieved multi-column sorting while only a single column should be able to be sorted (default value of sortable is single!​).​
If you have server side sorting on, you will notice you will receive 2 objects in the sorts object.

Hi,

I use Cascading DropDownList (with data from service) on my page. Control is default hidden(in div with style="display:none"), and becomes visible on click to proper button.

It is possible to load data on page load? By default data were loaded when control becomes visible..

Thanks

I have a mobile listview configured and working correctly to display a list of items that a user can select. They can select multiple items. When the user selects an item I simply add/remove the item from an array. The problem is that if they click the same item too fast then code code does not see the item in the array because the first pass through the click function hasn't finished when the second click happens. 

Is there a way to handle this type of situation

$("#selectList").kendoMobileListView({
        dataSource: ViewModel.get("itemsource"),
        template: $("#tmpl-selection-list").text(),
        pullToRefresh: false,
        click: ViewModel.itemSelected
});

itemSelected: function(e){
            var item = e.dataItem, addIt = true, currentItems = [];              
            currentItems = ViewModel.get("itemsource");
            if(item !== null){
                $.each(currentItems, function(s, _item){
                     if(item.blog_id === _item.blog_id){
                        addIt = false;
                }
             });
                    
             if(addIt){
                 currentItems.push(item);
             } else {
                 currentItems = $.grep(currentItems, function(o) {
                   return o.blog_id !== item.blog_id;
              });
            }
            ViewModel.set("itemsource", currentItems);
        }
 },
        

Hi all;

Just wondering if there's a way using Kendo on a mobile device to target a specific keyboard?  For example, some Apple apps I've seen with automatically default to the numeric keyboard or the phone dialer....

Thanks,
Jason

Hi,I am trying to populate a grid with remote data. All data, grouping, filtering, sorting is done on the server. Everything works smoothly when using aggregate data in the headers. But I want aggregate data in the footer as well. I came up with the following somewhat funky solution to display the aggregate count in the footer. This works ok with 1 level aggregation (allthough the solution is a bit ugly to me). But when I apply a 2nd level of aggregation this solution won't work. The 2nd level show the right count, but the 1st level just shows the count of the latest 2nd level aggregation. 

It may be of use to state that users will be able to define their own grouping by using the drag & drop feature of the grid.

I have attached a screenshot of the result of the current solution. The part in the red circle is what's wrong. I would want to have 2 rows with a count of 1 and 4 respectively.

Hi,

I am working on a nested grid and have a requirement to make the first column of the outer grid an "autocomplete" column.  Could you please point me to how I could accomplish this with the Kendo Grid?  Any and all help is appreciated.

Thanks,
Tom
