Using the HTML5 verison of Kendo UI in a grid. Many grid cells need a DropDownList, which I can populate with data no problem.

I cannot however filter the second DropDownList based off the first one. I have been through all the examples but nothing works.

I need to understand why my second dropdown is not filtering from the first one. What am I doing wrong?

I'm having trouble getting the read using a POST in a kendo.data.DataSource working.  It works fine for me using jQuery's $.ajax function, but not in the transport.read of Kendo's DataSource.

Here is the code running:

http://jsfiddle.net/jmowox1k/1/

It makes two Ajax calls, the first using jQuery way and the second using the Kendo way.  It sends the data as "application/x-www-form-urlencoded; charset=UTF-8".

The submitted form data is:

PropertyNumber=123&Address=1313+Mockingbird+Lane&AtRisk=Yes&FuelFacility=No&PropertyName=The+Munsters&City=Los+Angeles&Rec=Yes&DryCleaner=No&DCType=2&State=CA&OngoingEnv=1&ProjectType=2

I've attached two screenshots of Chrome's Developer Tools.  Using jQuery, it looks perfect, but using the Kendo DataSource, it's all mangled.

I guess I can just use the jQuery way and everything would fine, but I want to understand why recommended way doesn't work.

What am I doing wrong?

Using even the published demo code at demos.telerik.com, I cannot shift-tab out of a toolbar control.  This can be reproduced at http://demos.telerik.com/kendo-ui/toolbar/index:  get the focus inside the toolbar and press tab to go forward through the buttons, eventually exiting the toolbar and on to other items.  Again, put the focus in the toolbar and use shift-tab to move backwards through the elements.  The focus reaches the first button and stops - it won't shift-tab out.  

In my product's code, I experience almost the same, except the shift-tabbing seems to stop at the second button in the toolbar, not the first as seen in the demo.

Hi,

I am looking for an example on the syntax of a  kendo mvvm dependant(computed) observable when used in type script. 

Have not been able to find this anywhere.

Best regards

Ole

This started sometime late 2015 from what I can tell on the dojo page. It doesn't make sense and looks strange.

I have a html/javascript chart which I populate via an ajax call. On dataBound, i resize the chart xAxis max and draw plotbands based on the values bound to the grid. Unfortunately, the setOptions call seems to then fire the dataBound event again... and around and around it goes in an endless loop. I got around this by setting a flag so that it only processes the first time. However, the issue I now face is that when I pull new data into the chart later (say because the user expanded the data ranges), i cant reset that flag and let it fire the code in the dataBound event. So, when the user expands the date ranges there is a good chance that my poltbands and axiscrossing settings will be wrong. Any advice?  See below for code...

$.ajax({
        type: "POST",
        data: JSON.stringify({
            startDate: $('#txtDateRangeFilter').data('daterangepicker').startDate,
            endDate: $('#txtDateRangeFilter').data('daterangepicker').endDate
        }),
        url: "/User/EChart",
        contentType: "application/json",
        dataType: 'json'
    })
        .done(function (data) {
            var plotbandloaded = false;

            $('#currentDuration').text(Math.round(data.userGoalDetails.DurationHours * 100) / 100 + " hrs");
            $('#goalDuration').text(Math.round(data.userGoalDetails.Goal * 100) / 100 + " hrs");
            $("#chartE").kendoChart(
            {
                dataSource: {

Hi, 

I have been using the column menu to filter/choose columns to display in my grid and have been greatly pleased with the results.  However, I would like to add a second custom menu item to the column menu that has the functionality of the column menu, but the choices are determined differently...

so say my columns are human names, Aaron, Andrew, Dave, Dorothy, Evan, Eric.  Currently in the "columns" section of the menu, I can select which of those 6 I would like to display.  Is it possible to add a second menu item that will contain choices 'A', 'D', and 'E' as checkboxes and will display those columns starting with the respective letter? 

Hopefully that was clear enough.  Thanks for the help!

I am using the kendo UI with the following version Kendo UI v2016.2.714.

I have a kendo grid with add, update and delete buttons, these functionalities are working fine in all the latest browsers except IE11.

Do i need include anything to make it work for these button events or any other ways to get this done.

Hi,

Is anybody seeing the "blank context menu issue" in the spreadsheet? The menu contains 4 items (Cut, Copy, Paste and Merge) but they are not visible unless you hover over them

And the Cut, Copy and Paste commands don't work anyway, they cause a "do not use this function" message. See http://screencast.com/t/lsHfeO8FT

This is happening with the Q3 2016 release in Chrome, Edge and IE 11.
