[Solved] Checkboxes with CheckChildren gives poor performance

Hi there,

I've created a TreeView with checkboxes and CheckChildren set to true. When I check one of the higher level nodes (with around 100 children total) it takes several seconds to check them. Am I doing something wrong or is the JavaScript for this not very performant? I've managed to replicate the problem by simply increasing the number of nodes in the demo cshtml. A very simple jQuery command to check all of the checkboxes is lightning fast, so it doesn't look like a browser performance issue.

Many thanks,
Chris

Vertical scrollbar in hierarchy grid not activating when row virtualisation turned on

Hi,

This looks like a bug in Kendo UI Grid. Please try the following:

a) On the hierarchy example, turn off paging and turn on scrolling, but set the Employees grid to be scrollable. The scroll bar will then correctly take account of the child (orders) grid.

b) Now set .Scrollable(scrollable => scrollable.Virtual(true)) in the parent grid. The vertical scroll bar is no longer active, making scrolling in the child grid impossible.
Please advise,

George

[Solved] column.command.className breaks clickability of command button in grid

When I add the className property to a command in a grid I no longer receive the confirmation dialog. It seems the clicking is broken.

Here is the jsBin

Jon

Update:
The class on the anchor tag that received the className is "k-button k-button-icontext unassign k-grid-destroy k-grid-destroy"
The class on the anchor tag without the className is "k-button k-button-icontext k-grid-delete".

Why did k-grid-delete change to k-grid-destroy?

I'm using IE9 on Win7.

Android Holo Theme

Does the Kendo UI team plan on adding support for more of the Android Holo theme, for example the Action Bar and the Navigation Drawer? Also, any chance for a pre-build "Holo Light" theme? Thanks.

Range ("slider") Documentation / Examples?

Hi,
I'm wondering if there are any examples or documentation for the events for the range input control for mobile. I want to be able to update a label that shows the current value of the range control as it is slid, but a lot of googling later I only seem to find articles about the desktop kendo controls.

What events are fired by the control?
What are are the properties of the event parameter they generate?

Thanks

Bind RowVersion field to popup editor (byte[])

I have a need to allow the user to chose what action to take when a concurrency error occurs, I'm wondering how exactly I'd bind a RowVersion column to the Grid popup editor so it posts the timestamp back to my MVC action method? I was hoping I'd be able to simply designate it as a string in the data source model schema but I'm getting the error "The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters."

Has anyone else run into this issue? How did you resolve it? I'm guessing that javascript appends a "\0" when it converts the byte array to a string, so I (think) the work-around is to strip off the terminator character and convert the string back to a byte array in the grids...Save event?

Grid parameters to URL

Hello,

I'm new in KendoUI and I have one small question.
Is there any way to get Url paramters from Grid paramters? What I need to do is to catch each user action on a KendoUI Grid (actions like sorting, grouping and filtering) and replace the current page Url without refreshing. In this case, users can then easily share their views.

Can you please let me know if you have any recommandation, or native feature to help me doing that.

Thanks & regards.

Stack bar chart legend color issue

Hi,

I am looking for a way to assign color to a legend field. Please take a look at http://jsfiddle.net/ashriva/Cke4n/3/
In the above example I am trying to assign green color to the "Short" legend element to match its value field; similarly "Long" should be blue and "Flat" red.

Any help is greatly appreciated.

Thanks!
