I use a timebar + sparklines in all our dashboards. 

http://demos.telerik.com/silverlight/#TimeBar/FirstLook 
http://demos.telerik.com/silverlight/#Sparklines/Gallery

would be great to see an html5 version of the executive dashboard

Example: https://dojo.telerik.com/uqajAsas

Check the "foo" node. The change event fires for every checked node. It would be better if it fires a single time after all nodes have been checked.

On line 157 of kendo.aspnetmvc.js:

return 'datetime\'' + kendo.format('{0:yyyy-MM-ddTHH-mm-ss}', value) + '\'';

As far as I know this format is non compliant with any standard format.
Could this please be compliant with ISO-8601 standard so that its more universal for APIs to be able to handle?

Look at the emerging WASM projects such as Blazor or Ooui.  The obvious path seems to be to have a strong HTML based suite, i.e Kendo, ported to Blazor.  However another option would be to improve the Xamarin forms components to have comparable functionality to their desktop counterpartys so they can be used in LOB applications under Ooui.  The current Xamarin components are too mobile centric.  A third option, which admittedly seems like a bit of a long shot at present, would be to take Moonlight, strip out the plugin stuff, strip out all but the layout code, and redo that to write to an HTML Canvas.  Now that's probably outside your scope although in my opinion its the most attractive of the 3 options.  In summary I suggest you look at providing a full featured UI component suite that runs under wasm.

Dojo example.

1. Resize the browser window so that its height is smaller than the DropDownTree's popup height.
2. Click the DropDownTree to open its popup.
3. The popup opens and then auto-closes

Buttons that works like checkbox. First click it is on an highlighted second click it is off

<div class="filterField">
    <label for="filterTags">Tags</label><br/>
    <div class="filterFieldBody">
        <input id="filterTags"/>
    </div>
</div>
 
$( document ).ready( function ()
{
$( "#filterTags" ).kendoMultiSelect( {
    placeholder: "Select Tag(s)",
    autoClose: false,
    dataTextField: "text",
    dataValueField: "value",
    autoBind: false,
    dataSource: [
        { text: 'Summery Love Campaign', value: '1' },
        { text: 'Melbourne Cup', value: '2' },
        { text: '2018 Formals', value: '3' },
        { text: '2018 Schoolies Dance Club', value: '4' },
        { text: '2018 Schoolies Beach Fun', value: '5' },
        { text: 'Bridesmaids', value: '6' },
        { text: 'Wedding', value: '7' }
    ],
    //value: [], without value set to an empty array kendo ui assumes value:[''] but with an array count of 0
    // which causes all kinds of issues most especially when deleting
    change: function ( e )
    {
      tagIds = this.value();
      alert(JSON.stringify(tagIds));
    }
} );

} );
                    

Non-date values don't trigger change events...so I can't remove\fix non-date values

If you're gonna do that, then please at least make it so it ONLY accepts dates, like wipe the text if some non-date value is in there.

What you're doing to me is making me need to write my own blur\change for every date picker I use...ever...in anything

You've already got two "Material" themes, but they don't really seem to match the Google Material Design guidelines (http://www.google.com/design/spec/material-design/introduction.html). Would it be possible to add a new theme that accurately tracks the Material Design guidelines?

Reopen from http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback/suggestions/10600184-grid-in-combobox
Details about this widget were described in user comments.

Automatically add page breaks to PDF export, currently if exporting contents with very long contents it exports as one single long page, the page break should happen based on the Page size for example "A4"

That would be great if you create UI element Ribbon. With automatic buttons scaling on window resize.

A TreeView in ComboBox would be most helpful as both a stand-alone control and when editing within the Grid.

 something like this: http://www.brad-smith.info/blog/archives/193 (example from .NET Windows forms world)

* Used for relative small tree data structure.
* User may select one (many) item(s), without _loosing context_ (no interrupting dialog box, 'flat' interface).
* User may accept selection by click on item, or pressing 'enter'.
* User may cancel (hide) popup when click outside control/popup (ie in another control, that received focus) or pressing escape - like in combobox/dropdown.
* It will be nice if user can select items using keyboard arrows.
* After opening popup or selecting item, widget still has focus
* When user types in combo (with open popup), data should be filtered.
* No additional 'ok' or 'cancel' buttons to accept/dismiss selection.

I have a bar chart for which I wish to show the pointer cursor when hovering over the bars on the chart.  When moving off the bars in the chart the cursor should return to the standard arrow pointer.  I noticed that the cursor turned into the text cursor when hovering over the axis labels (left, right, and bottom) and on the legend.  So in addition to the above I would like the cursor to remain the standard cursor (arrow) when hovering over the axis labels and legend (since you cannot edit these).  I would also like the cursor to switch to the pointer cursor when hovering over the x-axis (bottom) labels.  

The reason for showing the pointer cursor for the bars and the x-axis label is to clue the user in that he can click on this area to show additional "driill-down" chart(s) when the particular bar or x-axis label is clicked.

Make it easy to add Kendo UI to ASP.NET projects and provide a NuGet package.

Kendo not support in Chrome latest version. it get flickering

Google Chrome is up to date
Version 61.0.3163.100 (Official Build) (64-bit)

I've been using the kendo.all.d.ts TypeScript definitions file from the beginning. While its quality has increased significantly overtime, it continues to have a lot of errors and omissions. I understand the Kendo UI TS definitions file is generated from the Kendo UI documentation. So the quality of the TS definitions file is only ever going to be as good as the documentation. And that's where the errors and omissions come from. Not everything is documented or documented correctly. I think the best Kendo UI TS definitions file can only be created when the Kendo UI source code itself is migrated to TS. Now that TS version 1.0 has RTM'ed it is time to do this. Spend an entire release doing this if you have to. Who knows how many bugs TS may expose and help to fix.

If there is a way that we can lock the top row of our grid and still use the browser scroll instead of their grid scroll? Right now we lose that top header row and it’s making everyone crazy. 

Currently in Kendo UI if a user sorts a grid column and leaves the page, when they come back the sorting has been reverted. I think there should be a way to automatically save the grids sorting state (potentially in cookies) so that when a user leaves the page and comes back, the state is how they left it.
