Hi Expert,
We are looking to use the Treeview Drag & Drop but would like to add some constraint, I am wondering if the current Kendo UI support what we're try to accomlish.

• Can we limit the child level of the parent tree?  We want to only allow 1 child per parent?
• Can we restrict user from creating the Top Level? 

We we try to accomplish is that we have a static list from the left hand side and we have 2 static parent on the right.  User must drag fromof the parent from the left.  The only condition is each of the level can only have 1 child node.
e.g.
Allow:
A
|---B
    |---C
        |---D
It cannot be where C&D is a child of B.  Can we prevent this?  TIA
A
|---B
    |---C
    |---D

Kendow UI Tree View 

When the ModelState returns errors to the datasource object, how does one find the grid row where the error occurred and then set it to edit mode? Thanks for any help.

With reference to the Kendo Code Library post titled Submit form containing grid along with other input elements, located here, I've found that "out of the box" it does not work in IE (I'm using v9), while it works perfectly in Chrome and Firefox.  I've experienced similar behavior when applying this sample to a project I am working on.  Any idea why this would be?  I thought all mainstream browsers are s'posed to handle Kendo UI without any issues?

EDIT:
I've found that if my move the Submit button's HTML so that it is BEFORE the Kendo Grid declaration, then it works in IE.  Why is this?

Selectors are not displaying down arrows, and the date picker, while usable, is not visible, on my PC.

If I publish the website from my PC, the problem appears on the live version - then another developer has to get the latest version and publish it to restore the appearance of the controls.

The attached image shows a browser with the controls working overlayed by a browser showing the same page on my PC.

I am using the same version of the MVC controls as they are. Here is a listing of my project bin directory:

Hi Everyone,

Here is my code snippet....
I need to know how to load the series data from information in the controller.

Hi, I'm trying to create a Grid with Filterable option but the Icon does not showup in the column, looks like it is invisible and when I click in the corner the menu pops.  What am I missing?

Currently we use a grid in batch edit mode.  When we click save changes, then the controller's Update method is called passing it all the updated rows.  Then the controller's Create method is called, passing it all the added rows.  Then the controller's delete method is called, passing it all the deleted rows.
Is it possible to, ( or if not, would you consider adding the feature) to configure the datasource to call a single "SaveAllChanges" controller method instead, which contains 3 parameters, one for the changed rows, one for the added rows and one for the deleted rows?
This is to enable scenarios in which the collection of rows needs to have validation applied that takes all rows into account.  For example, the items in the collection may not exceed a certain total Qty.  So if a user deletes one row, and adds another row, the controller will execute the Create method first, and this could cause a failure of the validation because of a defined Max Qty for all rows being exceeded; meantime the removal of the deleted row will actually cause validation to pass, but the Create method of the controller cannot know that when processing its validation.

Hi 

Im using kendoui 2012 q2.

Im trying to open a sub menu but it doesn't open when i hover over it.
Only when i define 

.OpenOnClick(true)
then when i click it, it's ok.

Thank you

I need to check whether the user can see the column or not. I need to hide a column if the user has no permission

The sort, group, and page functions are not working on my grid.  I have the code below and attached a picture of what happens when I try to group.  It's probably something simple but I'm not seeing it.
