Uncaught TypeError: Cannot read property 'get' of null

Hi,

I'm building a SPA with Angular JS and Kendo UI Widgets. On page load i got the following error in the console, but I don't really know where it comes from (but everything seems to work without problems):

Uncaught TypeError: Cannot read property 'get' of null

makeWidgetInfo @ VM4882:94
(anonymous function) @ VM4882:507

Does anyone have an idea how to fix this?

Thanks!

Gantt : with more than 10 tasks, Chrome reorders, (IE and FF are fine)

Hi,

I'm using the Kendo UI Gantt widget (the latest version).

When I add more than 10 tasks, only with Google Chrome, the tasks are not in the correct order.

I have attached a test project and 2 screenshots of the bug.

[Solved] Custom popup editor AngularJs Validation DropDownList

Hi,

I read many threads about validation in kendo UI, but I don't find what I'm looking for. I have a grid with Custom Popup Editor and AngularJs like this example. When I add a validation in the schema for my grid data source, User cannot save. Because it is a dropdownlist with a default value, required validation does not work. I tried this example for custom validation, but message is not shown. I added this line in the template for popup editor:

<span class="k-invalid-msg" data-for="AssignmentType"></span>

It works for a simple textbox, but not for a dropdownlist.

Any ideas?

Note to Telerik Team: There is many documentation everywhere very nice, but when we use dropdownlist in a grid, it is difficult to find the right way to go.

My two cents

Thank you

[Solved] How to set SubGrid data binding conditional?

Hello:

I've followed the demo to setup the master/detail grids (or hierarchy grids), they works fine as intended.
However I'd like to make improvement by asking how to make SubGrid data binding conditional.

By default if the MasterGrid returned 10 rows, then the data binding to the SubGrid, which is the url to Controller/Action, were called 10 times, with each one pass in the different ID from MasterGrid.

In my case I only need to call the data bind to SubGrid when a value in MasterGrid has met the requirement.
i.e. for each row of MasterGrid returned, only if the column MyFlag=1, then I need to call the SubGrid.
So out of 10 rows turned, if only 3 rows has MyFlag=1, then the data call to SubGrid only need to be 3 times, instead of 10.

I am not sure how to do that, please advise.

Thank you,
