I ran into the same problem illustrated here: https://www.telerik.com/forums/inline-cell-edit-functional
However the solution is unusable with large lists (even with paging) due to the obvious iterations, the lag between character inputs is horrendous. This is not an issue with other inputs such as the number input editor, only the text editor. Has there been any discussion surrounding this, the input control should keep track of this independently instead of needing to cycle through the entire data list on every keystroke.

We have introduced a new property of the Grid, dataItemKey:
Could you try using it, as it should improve the performance and remove the lag?
Please let me know whether this solves the issue or if you need further assistance.

Hi Krissy - I am using the dataItemKey, however this is in regards to in cell editing, as described in the referenced post. The text editor for in cell editing has some severe limitations (see original post).
The way the item changes are handled is up to the developer.
Hope these resources are helpful.

Thanks for the response, what I was more concerned with is the actual implementation of the default cell text editor, it seems like it should be handling its own edit state while in edit mode instead of requiring the calling code to update changes on every single keystroke. For anyone else who runs into this problem, this is what I used:
Thank you for sharing your solution, it looks great.
The reason why the default cell text editor behaves like that is due to the fact that we do not know whether the developer would like their application to be statefull or stateless and we do not want to cause further complications.
