How to make the below snippet to work? Null is making the problem, but I need both combo and to allow null values in the column.

Hello,


try to set “null” as a string:


mygrid.parse([[1,“a”], [2,“null”]], “jsarray”);

#3

If by null you mean the empty value, you can also try to use

mygrid.parse([[1,“a”], [2," "]], “jsarray”);

Thanks for prompt reply.

Actually the data in array comes from the database and it would be odd to have to replace all null values (which is common in databases) to empty strings manually and then to revert all “” to nulls to post back the changes. I think it is a quite common case and thus it should be handled by the library out of the box. If it’s not supported how should I do it? Implement grid._process_custom_jsarray_row and call  grid.load(url,“custom_jsarray”)? Is there a hook for reading values from the row to replace “” with nulls automatically?
