I'm trying to create a drop down list with grouping where I custom sort the data by group in a non-alphabetical way.  I've created a sort function that I run on the data before I pass it to the Kendo DataSource and if I output the array to the console at that point the data is in the correct order.  Once I create the Kendo DropDownList though it seems to break the sort and puts back to alphabetical order.  I further tested things by turning grouping off on the drop down and in that case the drop down displays the data in the correct order as sorted by my sort function.  Any ideas?

 The data is an array of objects that look like:

The sort function is

The function to build the drop down is

 which is then called by

Hi, Kendo newbie here,

I've been evaluating whether the Grid control or the spreadsheet control is best for my application requirements.  I'm leaning toward the Grid, but I'd like to get a second, third, nth opinion.

In general, I think the Spreadsheet is overkill, and I like the aesthetic of the Grid much more.  However, here are some features I need that I don't see in the Telerik demos.

I'd like my user to be able to easily duplicate one or more rows:

- Either by checking off the rows with shift-clicks, or in some other way highlight and select multiple rows.

- duplicate the selected rows with a button and/or keystroke

Thoughts?

Thanks in advance.

Hi,

I want the grid to fill the available space and have virtual scrolling so I'm using a flex layout with the grid set to 100% and it sits in a div with style:

  flex: 1 1 auto;

Its almost working except the horizontal scroll bar that appears at the bottom of the grid overflows the containing div and hence causes a scroll bar on the browser.  It looks like the border on the horizontal scroll bar is at least part of the problem.  If you look at the attached image from the bottom left of the window you can see that in the red rectangle that I've added it shows a grey bar which is not part of the enclosing div. Do you have an example with: virtual scrolling, a horizontal scrollbar, and the grid filling the available space using flex?

Thanks,

We are currently re-assessing our usage of the Kendo Map in our web application. While our needs have been fairly basic until now, in the near future we will require more advanced features.

Reviewing the  Release notes it appears that aside from bug fixes, little has been done to the map control since Q2 2014 or Q1 2015 if you count exporting via drawDOM as significant.

Looking at the Roadmap (http://www.telerik.com/support/whats-new/kendo-ui/roadmap) there is nothing relating to the map.

http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback has many feature requests that would make a big difference to the map, but virtually none of them have been implemented. For example (http://kendoui-feedback.telerik.com/forums/127393-kendo-ui-feedback/suggestions/5905068-marker-clustering-support-on-kendo-ui-map)  has a large numbers of votes and has been around for over 2 years 

Given the above, from my perspective it looks like functionality wise the map control is stagnant. Therefore we are not filled with confidence in using it in our map-centric application.

Can you offer any insight into whether or not this is a valid conclusion, and also into relevant future plans (if any)

Thanks

When trying to input some data into the field in the filter menu from the column menu, the menu collapses making the filtering totally unusable.

This bug can be seen on the Kendo UI demo pages

I have created a screen recording showing the issue.

I am using Windows 10 latest + Chrome latest

Hi Team,

In a locked column in grid, When tablet orientation change continuously multiple times with some fast speed, the selected row is dividend in different selected row for locked and unlocked column. This is a intermittent issue. While moving in slow pace this issue may or may not occur.

I've configured my kendo grid to call a custom service upon clicking "Save Changes" button.  Function call is as follows:

Does calling preventDefault() prevent the grid from resetting the return value of hasChanges()?  When I make a change the value is true.  I was hoping that after clicking "Save Changes" it would revert to false, but it does not.  I tried adding a line after the grid refresh to manually run the cancelChanges() method, but that undid the changes in the grid display.

Is there any other method to take the grid out of edit mode?

Thanks in advance

Hello,

I'm using scheduler in a very simple mode - a read-only month view. I'd like to read from the server every time the user navigates. I have found some sample code on this forum from 2013, however the latest library code is a bit different.

Anyway, I have an ALMOST working solution. I have serverFiltering = true, and my Controller method is set up to work with DataSource filtering:

public virtual JsonResult HistoryData(Guid id, [DataSourceRequest] DataSourceRequest request)

However, the scheduler JS library fails because it expects the data to some back in a simple list format. The controller is obviously returning a "filterable" format like so:

Data->

    Total:1

     Filters: ...

     Errors: ...

     Data: [...]

So my question is, if we're using serverFilterable flag to force the reads, shouldn't I be able to use [DataSourceRequest] in my controller?
Could you please provide an up-to-date MVC project sample for this scenario?

Many thanks.
