I have a Kendo UI Grid on my Razor Layout which fetches data from the controller.
In this grid I wish to have a set of 3 DropDownLists which are:
ProductGr
The easiest way would be to use the cascading dropdownlists: http://demos.kendoui.com/web/dropdownlist/cascadingdropdownlist.html inside of the editor templates for each of these columns.
If you are using popup editing you might consider customizing the popup menu like here: http://www.kendoui.com/code-library/mvc/grid/custom-popup-editor.aspx
If you are using InLine editing you should use this approach to customize the editor templates: http://docs.kendoui.com/documentation/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/editor-templates
If you are using InCell - lets just say its not possible.
