Hi,

I am using an endless scrolling list view in my app. Recently added the ability to scroll to the top of the page, but the performance is really bad. Most of the time I simply get a blank page and I have to scroll up and down to see anything. It can be easily reproduced in your demo:
http://dojo.telerik.com/OqEGI  (original - http://demos.telerik.com/kendo-ui/mobile-listview/endless-scrolling#/)

Just change the header to this:    <span data-role="view-title" onClick="app.view().scroller.scrollTo(0, 0);"></span> 
How can I workaround this bug?

Hi.
Hoping you can help.

I have been using your demo at
http://demos.telerik.com/kendo-ui/mobile-listview/hierarchical-databinding#hierarchical-view?parent=2  in order to learn how to bind to hierarchical data.

In my data, (outline structure below), you'll see that the elements with children are called 'ChildNodes'

How do I build the list, as per your example, so that the ChildNode elements appear ready to load in their data?

Tree struct:
--Root level
----ChildNodes
----Active (bool)
----num (int)
--------Active (bool)
--------ChildNodes
------------Active (bool)
------------num (int)
----------------ChildNodes
--------------------Active (bool)
--------------------num (int)
------------------------Active (bool)
------------------------ChildNodes: []
--------------------Completed: int
------------------------Description: string
------------------------ElapsedSeconds: int
------------------------Guid: string
------------------------Id: int
------------------------NodeType: int
------------------------ParentId: int
------------------------PersonId: int
------------------------Project: string
------------------------ProjectId: int
------------------------State: string
------------------------WorkItemType: string
--------------------...
--Completed: int
--Description: string
--ElapsedSeconds: int
--Guid: string
--Id: int
--NodeType: int
--ParentId: int
--PersonId: int
--Project: string
--ProjectId: int
--State: string
--WorkItemType: string

Many thanks in advance.

Hello,

I have created Numeric textbox in Grid. I Don't want it to accept decimal. Why does it accept decimal? I dont want to use custom editor to specify decimal places.

dataSource = new kendo.data.DataSource({
            data: myArray, //empty data
            schema: {
                model: {
                    id: "id",
                    fields: {
                       
                        MINUTES: {
                            type: "number", validation: {
                                decimals: 0,
                                required: true,
                                min: 0
                            }, format: '0.'
                        },

It should accept only number. Please help.

Hi.

I've noticed that when uploading multiple files in async mode the progress bar reaches 100% and then starts over again. This goes for about 3 times. It happens specially when uploading big files (over 100 Mb). I've register a handler to the progress event and log to the console. In the extract below from chrome browser you may see how the file.004 reaches 100% and then starts a 1% again.

I'm using NTLM for authentication and I've noticed the has header WWW-Authenticate: NTLM message everytime that the progress bar goes from 100% to 1%. I think that the file payload is sent 3 times for every http request of the NTLM handshake which is really bad.

Is there a way to solve this?

I've also noticed that the upload component starts the upload of all the files at the same time. In our case the user may salect to upload thousands of files so I would be better to have the control to send only 4-6 files simultaneously, or even being able how many.

Attached is the full log for an upload of 6 big files. Because of implementation issues I can only test the upload in Chrome.

Thanks

Hello,

Is there currently a supported way of adding new elements to the diagram using the ShapeOptions type that also provides the underlying dataItem? Currently I can do diagram.addShape(shape, options) to pass in a ShapeOptions object, or diagram.dataSource.add(dataItem) to provide the dataItem and rely on the shapeDefaults. I would like the ability to combine this functionality by either passing the dataItem as part of the ShapeOptions object or as a parameter to a method with the ShapeOptions.

Thanks

I'm trying to dynamically populate the dropdown list on the grid filter popup. A sample of my approach so far.


This seems to be working to update the list just fine. However, the height of the dropdown is getting messed up after subsequent updates. The first time it opens, a scrollbar is correctly shown. Each time thereafter, the height is 'auto' and no longer shows a scrollbar. I believe I've isolated the cause down to the popup deliberately calculating height on first open but never again after.

Changing the .one() call to a .bind() fixes the scrolling issue but I'd like a solution that doesn't involve manually tweaking internal Kendo UI code. Is there a better workaround that will force the popup to recalculate its height on open?

Hi,

I want to know if there is a manual way to commit changes in Data Source for specific rows only and not all data. Is that possible?

Thanks

Hi,

I am creating records in batch using Grid / External Form.

Is there a way to commit changes on records inside Data Source manually? i.e. newly  created becomes existing records and those updated becomes updated and committed?

Thanks

In one of our editable fields, I've changed it to a readonly textarea for display - because there's sometimes quite a bit of text, how can I change the container for editing that data in to a textarea?

Thank you very much for your time!

I'm having a hard time getting a model property of type 'date' to bind to inputs of type 'date', 'datetime', or 'datetime-local'. I think the problem is that these inputs require value to be in a particular format or it gets ignored, but the binding isn't formatting the date properly.
<input type=date> requires 'YYYY-DD-MM'
<input type=datetime> requires 'YYYY-DD-MMTHH:mm:ssZ'
<input type=datetime> requires 'YYYY-DD-MMTHH:mm:ss'

Also I can't tell if it's properly parsing the value from the different types once a date is selected.
