Current when using the HierarchicalDataSource you can only load one level of data at a time. I would like to be able to pre-populate the entire tree (but have the ability to refresh it via remote data, should I so need).

@Html.DevExpress().ComboBox(
    settings => {
        settings.Name = "comboBox4";
        settings.Width = 180;
        settings.SelectedIndex = 0;
        settings.Properties.DropDownWidth = 550;
        settings.Properties.DropDownStyle = DropDownStyle.DropDownList;
        settings.CallbackRouteValues = new { Controller = "Editors", Action = "MultiColumnComboBoxPartial" };
        settings.Properties.CallbackPageSize = 30;
        settings.Properties.IncrementalFilteringMode = IncrementalFilteringMode.StartsWith;
        settings.Properties.TextFormatString = "{0}";
        settings.Properties.ValueField = "CustomerID";
        settings.Properties.ValueType = typeof(string);

        settings.Properties.Columns.Add("ContactName", "ContactName", 130);
        settings.Properties.Columns.Add("CompanyName", "CompanyName", Unit.Percentage(100));
        settings.Properties.Columns.Add("Country", "Country", 60);
        settings.Properties.Columns.Add("Phone", "Phone", 100);
    }
).BindList(ViewData["Customers"]).GetHtml()

We need the bar of series to be draggable and also its value can be changed on drag.
For example, a user is given a chart like below link:
http://demos.kendoui.com/dataviz/bar-charts/column.html.
Below the chart, a table is given for data. Chart is loaded with false data. User is expected to plot the correct graph based on the table data given. For this, user will drag the bar in up/down direction to set it to the desired value.

It would be nice to have onClick callback as a part of drawing props in spreadsheet.
Scenario:
When I have more than one image on a spreadsheet, on click of those images I want to get info about the image more specifically range of the topLeft cell the image is attached to.
I have explained a lil bit more here, and I also have a work around here for now but if we have onClick call back it will give us bit more control over the images in spreadsheet. 

It would be nice that export-to-excell feature supports the text orientation which is supported by MS Office and Open Office. This feature lets the user to have vertical text in the worksheet.

It would be beneficial to add additional support for tooltips natively on the Bubble Layer in RadMap

Merge ListView and MobileListView implementations to have a single ListView with support for Grouping, PullRefresh, Infinite Scrolling etc.

For ex. Using a MobileListView with a single item per row on an ipad pro is a waste of space. But there is no support for applying grids ( purecss or bootstrap ) to the mobile listview. This is possible with the web listview but then you lose features like grouping, infinite scrolling, load more, etc.

Hence please make a single SuperListView with wider functionality support. 

It would be nice to have navigation methods like 'nextRecord', 'previousRecord' to select grid records. These methods must  take care of paging issues and load next/previous page automatically and select the correct record afterwards. I've implemented these methods on my side nut it would be easier to have them natively as part of the grid implementation.

Provide or change the current default value of Aggregation from 'Max' to 'None', so that user can select his desired aggregation from UI.

Implement an option to preload some data for mobile list view in endless mode. This would increase UI time because there is allready data defined in HTML to view, the user must not wait for a datasource to load

I love your controls except Validator. I have finally made my own, where I can write multiple functions to evaluate each input just like this in typeScript:
new Helpers.Validate([
                { name: 'postId', test: [(e) => { if (e == "") return "Chose a post."; }] },
                { name: 'creditor, test: [(e) => { if (e == "") return "Chose a creditor"; }, ] },
                { name: 'description', test: [
                    (e) => { if (e == "") return "Make a description"; },
                    (e) => { if (e.length < 15) return "Your description are to short "; },
                ]
                }, ]);
It is now a pleasure to make forms and perhaps you will consider to reevaluate the structure of your Validator that I have been struggling with workarounds on for so many hours the last two years.

Expand your Moonlight theme for use with the Mobile UI

when the mobile view uses a header, containing a toolbar as header it would be nice to be able to have a view title like in the navbar.

Box Plot (Box and Whisker) works great but would like to have Vertical instead of horizontal.

If we need to run some code in all of views, there is no way to do it besides add the call to each and every view in the project. In a large scale project that might have 100 views in many seperate folders and sub folders - this become a nightmare.

You should add the ability to add a generic event to all the views (kind of a "base class" for view) or by implementing the attached event via the application definition [var app = new kendo.mobile.Application()...]

Thanks,

What control would I use for an 'Infinite' data scroller?

Where you have a horizontal div that is loaded initially with 4 divs, 2 of which are viewable in Portrait mode and more in landscape mode, but when you pull from the right, flicking to the left to get more content an ajax call get more.

This example is common on Amazon product pages of related products, but there you have to tap on the right  cheveron/arrow to fetch more, where as a smoother approach is to load more into the non-visible part.

I have only seen examples so far of infinite scrolling from the bottom in jquery.

I imagine that you would have got this solved already, so can you give me an example of I guess your data source component feeding a div with extra divs from the right. There must be a suitable trigger point so the spinner is not going forever due to a slow load. So I guess when a 

I am trying to work out what divs need to be in the page preloaded, and what can be fetched from the server.

Enable chart interactive features with Canvas rendering.

I would like to the see a feature wherein I can set additional target lines for a bullet chart. This is helpful in scenarios where I need to indicate a target and benchmark. I was able to see similar questions in your forum http://www.telerik.com/forums/set-target-range and also one on stack overflow http://stackoverflow.com/questions/25303748/kendo-bullet-chart-with-two-target-lines 

I've been trying out your new Drawer feature (which is awesome to have), but I've had to go back to the one I already coded because of a couple of missing features, that I find to be part of the standard usability of the native drawers:
* There's some quirkiness when I click on the button to expand; sometimes it registers two clicks and immediately closes the menu.
* If I open the drawer, and I'm already on a section (e.g. Settings), if I click on Settings again, I want it to close the drawer. Right now, since it is not navigating to a new view nothing happens. In my code I like to register any click on the drawer as a closing action, though I recognize that this may not work for everyone.
* I use a listener so that whenever the view changes in the application the drawer is also closed. This handles the case where some button on the drawer may do some processing, and may or may not change the view, but if it does, I'm ready to use that view, and should now be taken directly to it. For example, a Facebook login button. If the app is already authorized, and the user logged in, clicking a "Connect" button in the drawer may run background code and just change the button text from "Connect" to "Logout". But, if the user is not logged in, then it closes the drawer and shows the login screen.
* I like to tie the Android menu button to the menu toggle function with onDeviceReady and the Cordova "menubutton" event.
* I also like to tie the Android back button to first check if the drawer is open. If so, it closes the drawer and does nothing more. If the drawer is closed instead, then it allows the action to carry on to the next handler.
* The last point is personal preference (and I wouldn't care if the other features above existed), but I prefer that the titlebar stays in place, and the drawer slides out underneath of it, only covering the .km-content and .km-footer areas, and not .km-view-title.
