Grid editable input type

Is there any option to enter only numbers when entering Grid?

You may try to use the aftereditStart event to get the editor input element and set it’s type to the “number”.
For example:

We updated the numeric editor for the dhx.Grid in the latest dhx.Suite update (v8.3).
Now you can use only the numbers in it:

Please, download the latest available dhx.Suite build from your client’s area to get this fix.
Thank you for your report.
