Hi Vinod, I have recently upgraded from version 3.8 to 4.4.5 and have de same problem as you.

I use exactly de same method, loading from jason with loadonce activated, so page resizing and sorting is made client side.

When editng rows with form, the grid does not reload the modified data.

I think this is either a bug or a change of behavior, I couldnt find any documentation on this.

Even using the edit option reloadAfterSubmit:true does not refresh de grid.

I think it could be because of datatype is set to local when using loadonce and in previous versions this setting was ignored and performed the ajax request.

The solution I found is to override afterComplete in editing options and trigger the reload manually.

Did you find any other way to do it?

Bye
