I have the issue in my code, but I also tested it in your demo site and it has the same problem.

I have uploaded a screen dump of the error output from Chrome.

It is in or after the DataBinding event (Comming from Create action), the the error occurs, thus causing the Delete action and refresh of the UI to never occur.

The bug occurs in both Chrome and IE Edge.

Please fix the bug.

Bug report

In FileManager read request is triggered twice when navigating to a parent folder that has a nested folder. The issue does not occur if the folder contains only files without a nested folder.

Reproduction of the problem

1. The issue can be replicated if a nested folder is created in the demo service. The screencast here demonstrates the issue.

Current behavior

Two identical requests are sent when the parent folder is selected.

Expected/desired behavior

There should be a single request when navigating to a parent folder, even if it has a nested child folder.

In our use case, we have linear gauges that show different colours depending on the time of day.

Our users need to be able to move the pointer up and down to view the corresponding values. 

As you can see in the below image, currently we have a workaround to show a slider above it and then move the pointer up and down accordingly, as the slider is moved. However, this does not always work perfectly, and sometimes the slider doesn't line up.

It would be nice if there were an option on the linear gauge to make the pointer moveable (false by default) and then also have corresponding events e.g. when the movement starts/stops.

Incorporate page breaks into the Gantt PDF Export and include option to repeat column headers on each page.

The DropDownList's Keyboard Navigation Docs specify that the arrow keys move the highlight in the dropDownList, while Enter selects the highlighted item.

However, in reality, the arrow keys already select items. Via keyboard, it is not possible to select e.g. the third item in the list without selecting the first and the second item first (by pressing the down arrow).

E.g. the docs for Angular describe a different behavior.
