Yes, that should be possible. But the effect of clicking on a field depends on the type of data in the relevant field. But one click on a text field or number field should be sufficient to edit the value, if you have enabled inline editing.
Perhaps you have selected the use of the popup editor? From the manual:
There are two ways inline editing can be done – using the standard editor and using the popup editor. The standard editor lets you edit each cell individually while the popup editor displays a popup window for the entire row. With the standard editor changes are saved after the user leaves the current cell and with the popup editor the changes are saved only when the user clicks on the Update button for the entire row.
To have single-click editing, the popup editor must be switched off.
Note that the Kendo UI documentation refers to 3 supported editing modes: "incell", "inline" and "popup". What AIM calls "inline" editing is actually incell editing if the popup editor is switched off.
