To better explain what I'm looking to do I adapted a sample from the cascading dropdownlists. View JSFiddle example  The issue is with the data format...

Work flow is that we have selected a town. Then all the streets in that town are populated in DDL. Once street is selected, then all the street numbers on that selected street are populated in the last DDL.

Note: The mock data is a sample of the real data with much less. Code from the existing REST endpoint creation can be viewed in here: REST C# endpoint

What tweaks do I need to make to take advantage of this perfect example for a cascading dropdownlist?

Thanks in advance!

Hi,

Kendo Web 2013.2.918 no longer has the DropDownList.enable(enabled) function.  It appears that this has been removed from your documentation as well.  But, interestingly, it is still in the demos on your website.  Did you remove this?  Why?  Now I have to use readonly and then set the disabled styling manually which is doable but what a hassle for people upgrading.

Hi Kendo team,

I have a problem with reading the datasource. 

 data = new kendo.data.HierarchicalDataSource({
//----i am using this one---
                //transport: {
                //    read: function (options) {
                //        $.ajax({
                //            url: '/Inventory/GetcategoryTree',
                //            type: "GET",
                //            dataType: "json"
                //        });
                //    }
                //},
//-----or this one------
                transport: {
                    read: {
                        url: function () {
                            return '/Inventory/GetcategoryTree';
                        },
                        create: {
                            dataType: "json",
                            type: "GET",
                            cache: true
                        }

                    }
                },
                schema: {
                    model: {
                        id: "Id",
                        children: "Children"
                    }
                },
                scrollable: true,
                sort: { field: "CategoryName", dir: "desc" }
            });

Then i add the DS to the tree:


    var treeView = $("#treeview").kendoTreeView({
        dataSource: data,
        scrollable: true,
        dataTextField: "CategoryName",
        select: function (e) {
            this.expand(e.node);
        }
    }).data("kendoTreeView");

So now the problem is, when i call the treeView.dataSource.read() nothing happens and in debugger i see that the read() is undefined.(cant see it in the list of methods too)

Do you guys now when this ca occur, and under what circumstances. Is it the HierarchicalDataSource? I can see that the data source is there and i see the data too. However on break point in Chrome the dataSource is "B.extend.init"  

I want to collapse the node on single click. To do that i need to know if the node is expanded so i can call collapse(e.node)

Thanks a lot team

Hi !

i've got a problem to make my filter works,.
i'm doing a request to a file that contains some json code see below:

and here is my request :

when i'm using this function without any filter, it works perfectly.
i read the doc and i did try to add some filter by the same way and i get an object but without my data ...
by the way the 'fl' parameter i use as filter is a number (058500).
am i doing something bad ? 
thanks for reading and answering,
best regards :)

Hello,

I want to render schedule in a day view but time line should be rendered horizontal. All of the demo examples include timeline in vertical orientation which seems default. Any help is appreciated?

thanks

I have an autocomplete textbox working with an odata endpoint. In addition to the $filter that kendo generates I'd like to add an additional filter to eliminate "deactivated" items.

The approach shown in the code below works for grids, but (understandably) kendo uses its own $filter and ignores mine (in particular below, see $filter: "Hidden -eq false" bit):


Is there a spot in the autocomplete or datasource API where I can inject custom filtering? Alternatively I suppose I could create a special ODataController for ProductLines that only shows active items, but it seems "nicer" to just have a single ProductLines OData endpoint and let the clients describe what they want.

Hi!

I'm struggling a bit with recurring events again. This time, I'm trying to set up a monthly event to occur e.g. every first Wednesday. The event is rendered for some months, but not all. Also, the rendering does not seem to be consistent between views; e.g., the event might show up in Day View but not in Week View and so on.

The problems I reported earlier re. recurring events (which you fixed!) seemed to be related to a localized (Norwegian) setting, but this one also occurs in the online demos, e.g. the one at http://demos.kendoui.com/web/scheduler/index.html

Best regards,

Attached is the latest UI i'm developing to manage our attachments.

UI Description:
The UI is not wrapped in a form element.
'Select file' is a custom command on the toolbar on the Grid with a custom template being the kendo upload control. (autoUpload=false)
The Grid is grouped by 'Component Type'.
Reset and Save Changes are working buttons that work with our model to ensure validation.


Once we attach a file the generated kendo button $(".k-upload-selected") when manually clicked Calls our onUpload method.
When we try to wrap it behind Save Changes button like in our UI - onUpload is not called when invoked with
$(".k-upload-selected").click();  

So how can i make it work when invoked through javascript?
$(".k-upload-selected").click();   what am i missing?

Hi there,

I have a grid with a field with a custom editor.  This editor consists of an input field, and I have applied validation to this using the HTML5 attributes (required, min, etc). The field uses data-bind syntax to get/set the data.

This works correctly and I get an error message when updating the field with invalid values.  
However there appears to be a big flaw to how this works, the data-binding occurs BEFORE the validation it would seem.

Even if I enter an invalid value. the change event still fires on the dataSource and the new invalid value is set.  
This seems to me to be unwanted behaviour, if there is an invalid value I do not want this set in the datasource.

Is this by design? How can I stop the data source updating on a validation failure?

Thanks in advance,
David Asbury.

ps.  It is also possible to bypass the validator simply by pressing the escape key.  This kills the validation message and removes focus from the invalid control.   This also seems like a bug.
