jQuery Grid Plugin - jqGrid

Hi everyone,

I'm using a custom formatter to display an image depending on the data contained in 2 hidden columns of my grid.

After some user action in an independant dialog, the data in those hidden columns is updated.

I would like to know if there is any easy/efficient way to update the formatted column accordingly to those updated values? When the data changes, the formatted column doesn't update automatically...

Even if I've never managed to make the unformatter work for me, I've found various ways to update the column "manually" (remove then add row, or directly change the column's class for the chosen row, ...)

My problem is when I have many rows to update at once (using the multiselect mode), those looped manual actions take an awful lot of time.

I'm trying to avoid reloading the entire grid.

Can anyone think of any way to do update only the formatted column?

For instance, can the formatter function be called independantly, when the grid has already been built?
