I'm trying to get a Kendo UI Grid working with AngularJS and a sample of data. I am encountering a generic "Error: Invalid template" error when the grid attempts to display the data. The data I am using is:

I know it's throwing the error on the columns with numbers as headers, because when I take out those columns it works just fine. Also, if I swap those column headers out for letter values, it also renders correctly.

Is this a known issue with the Kendo UI Grid or is there a workaround? I know the data I will be displaying will have numbers as headers often.

Cheers

Hello,

I'm trying to make a filter with two filters inside .. !!

I have a MultiSelect and AutoComplete and I want to take the value of them and put them in a filter...

so what I did is this...

in onChange_MultiSelect I wrote this...

and in onChange_AutoComplete i wrote this ..

so basically what I did is, putting the value in two filters and then push them into a third filter and try to filter the Scheduler... 

but it's not working .. is there another way to approach this goal .. or any tip to make it right ??

Thanks in advance ...

I have a grid containing dropdown column bind to the field named ChartTypeId. It has a custom template which display the ChartTypeName. The problem, it sorts the column by ChartTypeId. How can I modify it to sort by ChartTypeName instead of ChartTypeId?

I'm attempting to update my (licensed) version of Kendo UI for Jquery and AngularJS to the newest release (2020.2.513 at this post). I downloaded kendo.all.js and put it in a new directory, then changed my links to point at the new directory.

Upon logging into my application, I get this trace in my dev tools:

Error: [$injector:modulerr] Failed to instantiate module core due to:
[$injector:modulerr] Failed to instantiate module kendo.directives due to:
[$injector:nomod] Module 'kendo.directives' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

My application worked fine with my previous version, 2016.3.914 and AngularJS 1.5.8, but now has issues. Can anyone assist?

Hi,

I am trying to save and restore settings of table header in kendo treelist. Is there a way to persist treelist as we can do in Knedo Grid (below link shows the example how to persist grid)?

https://demos.telerik.com/kendo-ui/grid/persist-state

As we dont have getOptions and setOptions in Kendo treelist, how can we achieve this feature?

Thanks,

Ramesh

Hi, I try to make dropdownlist create less "DOM" components to keep our app fast, even with lots of dropdown loaded with 100-1000 items.

So, I found that simple quick solution that works very well, I filter data on open / close to release "dom" items when I don't need them.

But, I have an issue when I apply a "contains" search.

Look at this

https://dojo.telerik.com/@foxontherock/OciGurUy/3

Open the combo, search for "trois" using the dropdown search box, then select it.

You will see, the combo re-opens, immediately when I apply the filter on the "filterOnValue" function.

If I don't set any "contains" search, it works well.

*** may I suggest to use that "DOM-trick" using filter on open-close the default behavior for all your components?  We plan to use it in dropdown, treeview, ...

We tried using "virtual", but there's too my bugs with it it never works as expected and it's too complicated. 

hi Kendo UI team,

here is the description of my problem.

Requirement : I need to plot Trendline and Standard deviation lines on a Scatter Chart. 

Problems : 

I tried to achieve this using kendo.draw.Path to draw Trendline and SD lines

But the problem is

1. kendo.draw.Path considers whole canvas as the plottable area with top-left corner as origin (0,0)
2. Scatter chart has origin at left-bottom with some margin based on axis labels
3. I could not figure out the mapping between chart coordinates & path coordinates 

Questions:

1. How to get the boundaries of Chart Area in coordinates?
2. How to get mapping between Charts data points and Path w.r.t. coordinates? i.e. the x,y coordinates of  the data (1023, 3250) is (150, 320)

The data for Scatter Chart varies from decimal points to 1000s (on both the axes) based on the user selection. Hence knowing the mapping between the actual coordinates and the data points only solves the problem.

thanks,

Srinivas

Hi and happy new year!

I have strange behaviour on my gantt datasource occurring when read request returns error 500. (i am stuck with specific endpoint which returns 500 instead of 404 when requested item is not found).

- I instantiate gantt widget and set all required options and datasource(s).
- Under read request specific project id is passed to the server. 
- Server responds with 500 and I catch it with error: function (e) {
return myErrorHandler(e, $scope); }, //Handler basically reads error and displays adequate message
- Gantt is rendered but it is empty as expected.

- I use my project selector and chose another ID that 100% exists. 
- I reset my datasource using new ID and use gantt.setDataSource to update gantt.
- Data is read from the server, no error.
- Schema: Parse is completed successfully with data. But no dataBound or anything else happens after and widget gets stuck on loading spinning wheel and doesn't populate data.

If first step is performed with correct ID (no error) widget is rendered correctly and then second step (opening other project) is working perfectly fine.

I tried with sync, refresh, read afterwards on the widget, but no success. I tried commenting out error handling implemented, but also no success.

I suspect error caught does something specific to the datasource and/or widget, but I cannot figured it out.

Any help/suggestion is more than welcome.

Thank you and regards,

Vedad

Hello, I am going to build a dashboard and am thinking about using a listview(or multiple) to house widgets/partial views.  I will store the users config in the db so I would like to fetch that and load the widgets dynamically into a kendo listview.  Is that possible?  Any code samples out there?  Is there a better way to do this.  Just trying not to code it all manually and trying to take advantage of drag and drop, sorting/etc...

Thanks
