Explain to me how I can work with the Selectable option.  I have 2 controls on a page.  On the left, I have a TreeList and on the right I have a Grid.  The TreeList contains a hierarchical list of groups for which the user is authorized.  I'm going to use this group selection to "filter" the data that will be displayed in the Grid control.  So, I need the selection of a group in the TreeList to prompt the refresh of the Grid which then must use the groupId of the selected TreeList's node.

1. On load, how can selection of a TreeList Node be set to a default group from a MVC Action? 
2. On selection, how can this value fire an event that will reload the Grid?

An example would be appreciated.  Thanks for your help,

Joel

Hello,
I am trying implement controls combo between TreeView and ListBox.
The available actions are Add - from TreeView to ListBox and Remove - only remove from the ListBox.
I am using simple buttons from both actions.

The problems after call ListBox.remove(..) are two:
1) the collection listBox.dataItems() remains the same - i.e. the item is deleted only from UI
2) the underlying select HTML controls remains the same - i.e. the MVC/Kenod validators validates the page even the ListBox seems empty

Here is my remove button handler:

I've recently started working on a new ASP.NET Core project and one element I've been working on is using a Kendo UI grid with a custom button with a text of "Approve". I'm using the Kendo Bootstrap-v4 style but this seems to be causing issues with the button icons. In my grids the standard edit and delete buttons show with the correct icons but if I set my "Approve" button to have a .IconClass("k-i-check") I actually get the download icon. If I choose the "k-i-edit" .IconClass instead then i seem to get k-i-check. If I choose "k-i-checkmark-outline" I seem to get "k-i-email". Is this something I'm missing or an issue with the latest version of the files I have in place? I'm using "Kendo UI v2019.1.220". This is only on my development machine currently.

Css reference as below:

Grid column

Thanks in advance for any advice.

Hello,

I have a requirement where the user needs to be given the ability to enter custom text inside a ComboBox if the value is not already there.  The ComboBox is bound to a model.  I'm not sure what is the best way to accomplish this.  Currently, in my controller I check to see if the Id of the entered text is equal to 0, and then I update the model data.  I am able to add the new value to the database, afterwards however, I don't know how to refresh/rebind the combobox to show the newly entered data.

Here's my Html-Helper code for the ComboBox:

Here's the code in my Controller to add a new value:

Any help is greatly appreciated.  Thanks.

For some reason the grid column headers have started to size larger than the default.  I just commented out any styles for the grids in this application that I declared overriding the default and the issue remains.

I can use this style to change the background color but the height has no effect :

.k-grid-header .k-header
    {
      background-color: red;
      height:20px;
    }

Please see attached.

the telerik asp.net mvc grid has the @item to access the bound item  inside a  .Template . There seems to be no documentation on what the replacement is for asp.net core grids . How do we accomplish this? Can you give an example of a .Template that uses a value from the data  

I've got a grid with InCell editing and I have only the Add and Save buttons in the header. The grid is in an iframe. The trouble I am having is when I click the batch save button the controller action in the Datasource is not getting called.
